Each one takes 2-3 minutes, costs nothing, and doesn't ask for your email. Built around concerns where the existing tools fail people.

Live
Keratosis Pilaris Body Protocol

Six questions, 12-week personalized protocol for KP (the rough bumps on arms, thighs, cheeks, or butt). Evidence-led ingredient categories, friction triggers to avoid, when to see a derm.

Solves: "How do I actually get rid of these chicken-skin bumps?"

Live
Perioral Dermatitis Trigger Eliminator

Seven questions to rank your most likely triggers (toothpaste, steroids, heavy moisturizers, fragrance) plus a "zero therapy" 4-8 week elimination plan. Anti-product by design.

Solves: "Why does the rash around my mouth keep coming back?"
Open the tool
Live
Skin Bump Triage — DPN, Skin Tag, or Mole?

Eight questions to identify if small bumps on your face are DPN, skin tags, sebaceous hyperplasia, milia, or something needing dermatology eyes. With specific safety notes for darker skin tones — the resource gap most existing tools ignore.

Solves: "What are these tiny bumps and what are my options?"
Open the tool
Live
Honest Acne Face Map Decoder

Pick the breakout zone, get the real dermatology reasons — not the discredited liver/lung/spleen folk theory. The only valid hormonal correlation (chin and jawline in adult women) is called out clearly. Everything else is mechanical and fixable.

Solves: "Why do I always break out in the same place?"
Open the tool
Live
Is My Acne Stress-Related? Quiz

Nine questions, scored across three patterns (stress-driven, hormonal, mechanical). Cortisol-acne is real and biologically distinct — and the protocol is two-front: gentle skincare plus actual nervous-system regulation, not "reduce stress" platitudes.

Solves: "Are my breakouts actually stress? Or is it something else?"
Open the tool
Live
Azelaic Acid Use-Case Finder

Tell us your concern (rosacea? PIH? hormonal acne? fungal acne? melasma? closed comedones?). We tell you whether azelaic acid is actually the right pick, what strength, how to layer it with your current routine, and when AzA alone isn't enough.

Solves: "Is azelaic acid worth adding to my routine, and which one?"
Open the tool
Live
Milia: Leave or Extract?

Eight questions to figure out if those small white bumps are actually milia (vs. whiteheads, sebaceous hyperplasia, syringomas, or xanthelasma), whether to leave them alone, and what extraction options are safe — with specific safety notes for eye-area lesions.

Solves: "What are these little white bumps and should I get them removed?"
Open the tool
Live
Rosacea Subtype Self-Test

Rosacea isn't one condition — it's four clinical subtypes (ETR, papulopustular, phymatous, ocular) that need very different treatments. Nine questions to sort you into the dominant pattern, with subtype-specific next steps.

Solves: "Which type of rosacea do I actually have and what should I be using?"
Open the tool
Live
Tretinoin Results Timeline Calculator

Most people quit tretinoin at week 4 — the worst possible time. Personalized week-by-week timeline showing what to expect for purge, irritation, and visible results based on your strength, frequency, and skin profile. Prevents the early-quit regret.

Solves: "How long until tretinoin actually works for me?"
Open the tool
Live
Rosacea Trigger Avoidance Score

Generic rosacea-trigger lists are useless because individual sensitivity varies wildly. Twelve questions about your lifestyle, climate, diet, stress, and skincare — we score your top 3 personal triggers and rank the changes most likely to actually reduce your flare frequency.

Solves: "Which of the 20 things on every trigger list are actually mine?"
Open the tool
Live
Hidden Fragrance Detector

"Fragrance-free" claims are mostly unregulated. Paste any INCI list — we flag every fragrance, essential oil, masking agent, and the 26 EU-regulated fragrance allergens. Useful before patch testing, mandatory for rosacea, PD, and eczema-prone skin.

Solves: "Is this product actually fragrance-free?"
Open the tool
Live
Closed Comedones Treatment Plan

The flesh-colored bumps that won't pop and don't respond to acne treatment are closed comedones — a specific type of clog that needs specific actives. Personalized 12-week plan using the evidence-led retinoid + BHA + azelaic combinations, including pregnancy-safe options.

Solves: "How do I get rid of these tiny bumps that won't pop?"
Open the tool
Live
Sunscreen Replenishment Tracker

Most people get 25-50% of the SPF they paid for because they under-apply. This calculator checks your real coverage vs the dermatology-recommended two-finger / quarter-teaspoon dose, plus tracks your bottle's 12M post-opening expiry and tells you when to reorder.

Solves: "Am I using enough sunscreen and is my bottle still working?"
Open the tool
Live
Comedogenic Ingredient Checker

Most online comedogenic ratings come from 1970s rabbit-ear tests that don't translate well to human skin. We flag the ingredients with the strongest human evidence (isopropyl myristate, lanolin, certain esters) — and skip the false positives that make every TikTok video panic about coconut oil.

Solves: "Is this product actually going to clog my pores?"
Open the tool
Live
Dark Circle Type Decoder

Under-eye darkness has four distinct causes — pigmented, vascular, structural, and fatigue — each responding to completely different treatments. Six questions plus a pinch test sort you into the right bucket so the eye cream you spend money on actually does something.

Solves: "Why do my eye creams never work?"
Open the tool
Live
Skincare Routine for Men

Tell us your real time budget (60 seconds? 3 minutes? 5?) and your shaving pattern — we build the actual minimum routine that matches your life, with shaving rules and a 3-product floor that handles 90% of dermatology.

Solves: "I have 90 seconds — what actually matters?"
Open the tool
Live
Teen Skincare Readiness Calculator

The Sephora-kids backlash has parents worried. This tool gives age-appropriate routines for ages 9-19 with explicit guidance on what to skip (retinol, eye creams, exfoliating acids) and what teen acne actually needs. Built on AAD 2024 guidance.

Solves: "What does my 11-year-old actually need vs what TikTok is selling them?"
Open the tool
Live
Pregnancy-Safe Skincare Checker

Paste your ingredient list, select your trimester. We flag retinoids, hydroquinone, high-strength salicylic acid, and the rest of the off-limits list — and tell you which pregnancy-safe alternatives (azelaic acid, niacinamide, vitamin C, low-strength glycolic) handle the same concerns.

Solves: "Can I use this during pregnancy?"
Open the tool
Live
Face Redness Reset Protocol

Persistent face redness has five distinct causes — barrier damage, contact dermatitis, over-exfoliation, rosacea, and post-procedure inflammation. Each needs different treatment. We sort which is yours and build a 14-day reset to calm the inflammation.

Solves: "Why is my face always red?"
Open the tool
Live
Scalp Bumps Decoder

Bumps on the scalp are one of the most misdiagnosed presentations. Could be scalp acne, bacterial/fungal folliculitis, or seborrheic dermatitis — and they need completely different treatment. Standard acne products often make the wrong condition worse.

Solves: "Why won\'t my scalp clear?"
Open the tool
Live
Body Acne Zone Protocol Builder

"Body acne" is too broad. Back is mostly fungal acne. Chest is often hormonal. Butt is folliculitis. Each needs different treatment. Pick your zone, get a targeted protocol — plus a possible-HS flag for the conditions that need a dermatologist.

Solves: "Why does my back / chest / butt break out and nothing works?"
Open the tool
Live
Ingrown Hair Prevention Protocol

Ingrown hairs have three distinct mechanical causes — hair texture, technique, friction. Most "prevention" advice mixes them and helps none. Tell us your zone, hair texture, removal method, and severity. We build a targeted protocol with skin-of-color laser-safety notes.

Solves: "Why do I keep getting ingrowns no matter what I try?"
Open the tool
Live
Slow Skincare Routine Builder

The dermatology-evidence alternative to 10-step maximalism. We build your minimum effective routine — the shortest list that addresses your concerns, calibrated to your skin, life, and budget. 3-5 products, $40-80/month. The list most people\'s skin actually needs.

Solves: "Do I really need 10 products?"
Open the tool
Live
Dehydrated vs Dry Skin Decoder

Two completely different conditions that need opposite treatments — and constantly get confused. Six questions sort which is yours. Catches the oily-dehydrated combo most quizzes miss entirely.

Solves: "Why does my moisturizer disappear 10 minutes after I apply it?"
Open the tool
Live
Chapped Lips Root Cause Finder

"Drink more water" doesn't fix chapped lips. Six root causes do — licking habit, mouth breathing, contact dermatitis, medications, angular cheilitis, environmental. Eight questions to sort which one is yours and what stops the cycle.

Solves: "Why are my lips ALWAYS chapped no matter what I do?"
Open the tool
Live
Build a Skincare Routine From Scratch (21-day plan)

For beginners staring at a wall of products with no plan. Three essentials in week 1, one product layered each week. Specific picks at three budget tiers, climate adjustments, age-specific notes.

Solves: "I have no idea where to start with skincare — what do I actually need?"
Open the tool
Live
SebDerm vs Rosacea vs Eczema Decoder

Three look-alike facial conditions that need completely different treatment. Antifungals for sebderm. Vascular and trigger management for rosacea. Barrier repair and topical steroids for eczema. Use the wrong protocol and you flare for months.

Solves: "Is this sebderm, rosacea, or eczema? They all look the same on my face."
Open the tool
Live
Skin Cycling Calculator

Skin cycling done right — adjusted for your experience level. Beginners get a 7-night cycle, not the viral 4-night version. Sensitive skin gets a 10-night cycle. Tretinoin users get a different schedule entirely. Specific product picks at three budget tiers.

Solves: "Should I really be doing the 4-night skin cycle if I've never used a retinoid?"
Open the tool
Live
AM vs PM Layering Order Decoder

"Thinnest to thickest" is half the truth. The actual rules are pH-based and absorption-based. Tell us what you own — we build an ordered AM and PM routine with timing notes, flag conflicting combinations, and add the sandwich method for sensitive skin.

Solves: "Does my vitamin C go before or after niacinamide? Does retinol go before or after moisturizer?"
Open the tool
Live
Skin Barrier Damage Test

Over-exfoliated, retinoid-burnt, or chronically reactive — score severity across the eight markers dermatologists actually assess. Returns a 2-6 week reset protocol with specific product picks and a reintroduction schedule. The hard part isn't fixing it; it's not breaking it again.

Solves: "Why does my skin sting from products that didn't sting before?"
Open the tool
Live
Hyperpigmentation Type Decoder

PIH, PIE, melasma, or sun spots? Four look-alike dark marks that respond to completely different treatments. Brightening serums fade PIH but do nothing for PIE. Tranexamic acid clears melasma but barely touches sun spots. Includes the blanching test that distinguishes vascular from pigmented in 5 seconds.

Solves: "Why don't my brightening serums work on my dark marks?"
Open the tool
Live
Sunscreen for Your Skin Tone

"Mineral SPF" doesn't have to mean ghostly white. The white-cast problem on medium-to-deep skin is solvable with the right tint, particle size, and reapplication method. Specific picks for Fitzpatrick I-VI calibrated for activity, climate, makeup use, and budget.

Solves: "Why does every sunscreen leave me looking gray?"
Open the tool
Live
Retinol Strength Selector

Tretinoin? Tazarotene? Adapalene? Retinaldehyde? Retinol 0.1, 0.25, 0.5, or 1%? Bakuchiol if pregnant? The wrong starting strength is the #1 reason people quit retinoids in a month. We pick the right family, the right strength, the ramp-up schedule, and the sandwich method for your skin.

Solves: "Which retinol should a beginner actually start with?"
Open the tool
Live
Salicylic vs Glycolic vs Lactic Acid Picker

Three of the most-used exfoliating acids — and they target completely different problems. Salicylic dives into oily pores. Glycolic resurfaces aggressively. Lactic exfoliates gently while hydrating. Mandelic for skin of color. PHA for rosacea. We pick the right one and the right strength.

Solves: "Should I use salicylic, glycolic, or lactic acid?"
Open the tool
Live
Slugging Decision Maker

For very dry, retinoid-recovering, or barrier-damaged skin, slugging is a fast track to a softer face by morning. For oily, acne-prone, or fungal-acne-prone skin, it's a 3-day clog factory. Eight questions to sort which side you're on, what product to use, and the morning cleansing protocol nobody mentions.

Solves: "Should I slug my skin or will it break me out?"
Open the tool
Live
Cystic Acne — Should You See a Dermatologist?

Cystic acne scars in 90% of untreated cases. OTC almost never controls true cystic disease. We score severity across the eight markers dermatologists use, identify red flags, and give an evidence-based answer on whether you need a derm now, soon, or whether OTC management is appropriate.

Solves: "Is my acne bad enough to see a dermatologist?"
Open the tool
Live
Whiteheads vs Closed Comedones vs Milia Decoder

Three white-ish bumps that look identical and need opposite treatment. Whiteheads pop. Closed comedones need months of BHA + retinoid. Milia don\'t respond to either — they need extraction. Squeeze a milium and you\'ll just bruise yourself. The right ID saves you 12 weeks on the wrong protocol.

Solves: "What kind of white bump do I have on my face?"
Open the tool
Live
Hair Removal Method Picker

Seven methods, very different outcomes — and the wrong choice for your skin tone, hair texture, or sensitivity profile costs you ingrown hairs for years. Laser doesn\'t work on light hair. Waxing wrecks sensitive skin. We match method to zone, hair, skin tone, sensitivity, and budget — and flag the technique mistakes that cause 80% of post-removal problems.

Solves: "Should I laser, wax, sugar, thread, or just keep shaving?"
Open the tool
Live
Eye Cream — Do You Need One?

"Start eye cream at 25" is the most-repeated skincare advice with the least evidence behind it. For most people, regular moisturizer + sunscreen works on the under-eye exactly as well as a $90 eye cream. We give you a straight answer on whether your concern (dark circles, lines, puffiness, hollows, milia) actually needs a dedicated product.

Solves: "Do I actually need a separate eye cream?"
Open the tool
Live
Dandruff vs Dry Scalp vs Sebderm Decoder

Anti-dandruff shampoo helps two of these and makes one worse. Moisturizing shampoo helps one and is irrelevant to the other two. We sort dandruff, dry scalp, sebderm, scalp psoriasis, and contact dermatitis based on flake texture, scalp oil, antifungal response, and pattern.

Solves: "Why won\'t my anti-dandruff shampoo fix my flakes?"
Open the tool
Live
Niacinamide vs Vitamin C Layering Tool

The "they cancel each other out" myth comes from 1960s research at concentrations modern formulations don\'t use. Reality: most layer fine. Eight questions sort which forms can layer immediately, which need a 5-10 min wait, when an AM/PM split is needed, and what to do during pregnancy.

Solves: "Can I use niacinamide and vitamin C together, and which goes first?"
Open the tool
Live
Tretinoin / Retinol Side Effects Decoder

A real purge, retinization irritation, and true barrier damage look identical at week 6 — and each needs the opposite response. Push through a purge and you reach the good results. Push through barrier damage and you cause months of additional damage. Eight questions sort which is happening.

Solves: "Is this retinol purge or am I actually damaging my skin?"
Open the tool
Live
Skin Type Test (Behavioral)

Self-reported skin type matches dermatologist assessment only 30% of the time. Most people confuse a state (dehydrated, climate-driven, post-routine) with their underlying type. Twelve behavioral questions across multiple time windows triangulate the real pattern — including the most-misdiagnosed oily-dehydrated combination.

Solves: "What\'s my actual skin type — not just how it feels today?"
Open the tool
Live
Glass Skin Routine Builder

Glass skin is real biology, not a filter — but the viral 10-step Korean routine isn\'t one-size-fits-all. Oily skin doing 10 humectant layers gets shiny, not glassy. Dry skin doing 4 lightweight steps stays tight. We build the right step count, textures, and order for YOUR skin and climate.

Solves: "What\'s the actual glass-skin routine for me?"
Open the tool
Live
At-Home LED Mask — Should You Buy One?

LED therapy has real evidence for acne (blue) and aging (red) — but most $200-1500 home masks deliver a fraction of the power used in published studies, and the wrong wavelength wastes the entire purchase. We sort whether your concern responds to LED, which wavelength, what power matters, and FDA-cleared device picks at three tiers.

Solves: "Are LED masks worth the money — and which one?"
Open the tool
Live
Bakuchiol vs Retinol Decision

Bakuchiol is marketed as "natural retinol" — but it\'s ~25% as effective, and it\'s only the better choice for specific situations: pregnancy, breastfeeding, retinoid intolerance, severe sensitivity. For most users with healthy skin, retinol delivers more results faster. Eight questions sort which is right for YOU.

Solves: "Should I use bakuchiol or retinol — especially during pregnancy?"
Open the tool
Live
Castor Oil for Eyelashes — Does It Work?

The viral castor-oil-for-lashes claim is mostly myth — zero clinical trials show castor oil grows lashes. What actually works: bimatoprost (prescription Latisse, 25% longer + 106% thicker), peptide serums (modest evidence), and stopping the things that damage lashes. We sort which path fits your goal.

Solves: "What actually grows my eyelashes?"
Open the tool
Live
Beard Skincare Routine Builder

The beard is the most-neglected zone in male skincare. Beardruff (seborrheic dermatitis), ingrown beard hairs, beard acne, dry skin underneath — each needs different treatment. We build a 3-5 product routine matched to your beard length, the issue you face, and the climate you\'re in.

Solves: "Why does my beard itch / flake / cause acne — and what do I actually use?"
Open the tool
Live
Crepey Skin Treatment Decoder

"Crepey" means structural collagen and elastin loss, not dehydration — moisturizer won\'t fix it. The treatments that actually work depend on body area, age, sun history, and how aggressive you want to be. Topical, in-office, and hormonal options ranked by evidence with tier-by-tier picks.

Solves: "Why isn\'t my moisturizer fixing my crepey neck/arms?"
Open the tool
Live
Sebaceous Filaments vs Blackheads

Most "blackheads on the nose" are actually sebaceous filaments — normal pore anatomy, not clogs. Pore strips and daily BHA clear them temporarily; they fill back up because they\'re supposed to be there. Real blackheads are different — and they respond to actual acne treatment over 8-12 weeks. Eight questions to sort which.

Solves: "Why won\'t my nose blackheads ever permanently go away?"
Open the tool
Live
At-Home Microneedling Decision

At-home microneedling produces real collagen stimulation at the right depth (0.25-1.0mm) with strict sanitation. The wrong depth, sanitation, or active condition produces scarring, infection, and PIH. The decision isn\'t "should I buy a roller" — it\'s "should I do this at home or pay for in-office, and at what depth?" Eight questions sort it.

Solves: "Is home microneedling safe — and which device?"
Open the tool
Live
Pregnancy & TTC Skincare Pause Timeline

Most "pregnancy-safe skincare" guides cover what to avoid once you\'re pregnant. The harder question is when to stop while trying to conceive. Tretinoin clears your system in 3 weeks. Hydroquinone is straightforward. Salicylic acid varies by concentration. Ingredient-by-ingredient pause schedule + pregnancy-safe swaps.

Solves: "Which products do I stop for TTC, and when?"
Open the tool
Live
Skincare on Photosensitizing Medications

Doxycycline for acne, certain antihistamines, blood pressure meds, NSAIDs — over 100 medications photosensitize the skin. Stacked with your retinoid and AHA, you can sunburn from a 15-minute walk. We map which of your meds photosensitize, how to adjust your routine, and how much extra sun protection you actually need.

Solves: "I\'m on doxycycline — what skincare do I have to change?"
Open the tool
Live
At-Home Chemical Peel Decision

DIY peel kits at 30-50% lactic/glycolic/mandelic produce real results — and real chemical burns if you skip neutralization or pick the wrong depth. TCA peels at "home" are dangerous. Eight questions sort the safe path: home peel at the right percentage, in-office for medium-depth needs, or just daily AHA serums.

Solves: "Should I do a chemical peel at home — and which strength?"
Open the tool
Live
Hair Growth Scalp Protocol

For pattern hair loss: minoxidil + scalp microneedling + finasteride (men) or spironolactone (women). Everything else — biotin, gummies, rosemary oil, $100 shampoos — has weak or no evidence. Eight questions map your evidence-ranked protocol with realistic timelines and what NOT to spend money on.

Solves: "What actually grows hair — and what should I skip?"
Open the tool
Live
Period Cycle Skincare Map

Skin behaves predictably across the cycle: clearest in follicular (use strong actives), oilier and breakout-prone in luteal (pull back), inflamed during menstruation. A cycle-aware routine produces better results without more product spend. Eight questions build a phase-adjusted plan.

Solves: "Why does my routine work some weeks and not others?"
Open the tool
Live
Travel & Long-Haul Flight Skincare

Airplane cabins drop below 20% humidity (the Sahara averages 25%). Add altitude UV, recirculated air, time-zone disruption, and you land looking 5 years older. We build a pre-flight, in-flight, and post-arrival protocol matched to your trip type — including a TSA-compliant packing list.

Solves: "Why does my skin look terrible after flying?"
Open the tool
Live
Eyebrow Growth Protocol

Most "brow growth serums" are either marketing or undisclosed prostaglandin. What actually works: bimatoprost (off-label), minoxidil, peptide serums, microneedling. What doesn\'t: castor oil, biotin, $80 brow oils. Eight questions map your safest path — including flagging FFA, thyroid, and alopecia areata that masquerade as plucking damage.

Solves: "What actually thickens overplucked brows?"
Open the tool
Live
Cold Sore vs Pimple vs Perioral Dermatitis

Three lip-area conditions that look similar but need opposite treatment. Cold sores need antivirals. Pimples respond to acne care. Perioral dermatitis needs the OPPOSITE of acne treatment — strip the routine, not add to it. Wrong-pathway treatment can extend a 1-week issue to 3+ months.

Solves: "What\'s this thing near my mouth — and what NOT to put on it?"
Open the tool
Live
Gym & Sweat Skincare Protocol

Sweat doesn\'t cause acne — sweat + sebum + makeup + bacteria sitting on skin too long does. Three-window protocol (pre, during, post-workout) matched to your activity. Detects the fungal-acne pattern (Malassezia thrives in workout sweat) where standard acne treatment actually makes it worse.

Solves: "Why do I break out after every workout?"
