TL;DR: Oral isotretinoin dries out every layer of skin. Here is a six-product, no-active survival routine for the four to six months of treatment, week by week.
TL;DR. Oral isotretinoin dries the skin, lips, eyes, and mucous membranes more aggressively than any other dermatology drug. The right routine is six products and zero actives for the entire course. Skip the retinoids, skip the acids, skip the foaming cleansers. The job for four to six months is moisture, repair, and getting to month seven.
The honest message I give every patient starting Accutane: the routine you are about to run is the most boring routine of your life. That is the point. Save the actives for month seven.
What Accutane does to your skin
Isotretinoin shrinks sebaceous glands by 80 to 90 percent, reduces oil production correspondingly, and changes the structure of the skin barrier itself. The visible result is the famous Accutane dryness: chapped lips, peeling around the nose, dry patches, occasional eczema flares, sometimes nosebleeds and dry eyes. All of it is dose-dependent and resolves after treatment ends.
Tool: chapped lips root-cause tool — finds the actual cause instead of cycling balms.
What it does not do is permanently weaken your skin. The barrier rebuilds within three to six months of finishing. The job during treatment is to support that barrier so it does not crack or get infected along the way.
The six-product routine
The structure: cleanser, lip balm, light moisturizer, rich moisturizer, occlusive, SPF. That is the entire shelf.
A fragrance-free, non-foaming cream cleanser. Morning and evening. Skip every acne cleanser you used to use. Salicylic acid, benzoyl peroxide, foaming sulfates, and any “clarifying” formulation are off the table for the entire course.
A heavy lip balm (Aquaphor, Vaseline, or a similar petrolatum-based product). Reapply every two hours. Lip dryness is the universal Accutane experience and starts within the first two weeks of treatment.
A light hyaluronic acid serum or hydrating toner under moisturizer in the morning. Surface hydration is helpful but does not replace occlusion.
A rich ceramide-based moisturizer twice daily. The BioCell Renewal Cream is the slot for readers who want a barrier-focused, fragrance-free option. Whatever you choose, it should be richer than what you used pre-Accutane.
An occlusive layer at night during the worst dryness phase, typically months two and three. Aquaphor, Vaseline, or a thicker balm patted over the moisturizer locks moisture in overnight. Slugging is genuinely useful here, even for people who normally do not need it. More on slugging.
Tool: slugging decision tool — skin types and routines where it helps vs backfires.
Mineral SPF 30 or higher every morning. Isotretinoin increases photosensitivity meaningfully, and any sun exposure during treatment is more likely to leave lasting pigment. Chemical filters often sting on Accutane skin; mineral is the more reliable choice.
The contrarian take: skip the actives for the entire course
You will read advice online that says you can keep using retinol, low-percentage AHAs, or vitamin C “in moderation” during Accutane. The mainstream dermatology view is the opposite: stop them all. Isotretinoin is already the most powerful retinoid you can use, taken systemically. Layering topical retinoids on top adds no benefit and substantially increases irritation. Acids do the same. Vitamin C is fine in theory but the skin during Accutane is so reactive that the threshold for irritation is much lower than usual.
The dermatologists I respect most are unanimous on this: minimum actives, maximum moisture, see you in month seven.
Week-by-week expectations
Weeks one to two: lip dryness starts, mild facial dryness. Begin heavy lip balm immediately, do not wait.
Weeks three to six: the initial “flare” some patients experience as the skin clears. Existing lesions can worsen before they improve. Do not abandon the routine. Add no new products.
Weeks six to twelve: peak dryness. Eyes may feel gritty, nose may bleed occasionally, eczema-like patches around the mouth or chin are common. Heavier moisturizer, more occlusion, possibly artificial tears for the eyes.
Weeks twelve to twenty: the clearance phase. The skin is dry but acne is meaningfully better. Maintain the routine without adding anything.
Final month: prepare for month seven by talking to your derm about maintenance adapalene. Most patients start it three to four weeks after the final dose.
When to see a dermatologist
You should already be seeing one monthly for blood work and check-ins during Accutane. Between visits, contact your derm if you develop severe eczema that does not respond to moisturizer, mouth sores that interfere with eating, eye pain (not just dryness), unusual mood changes, or significant peeling that exposes raw skin. The dose can be adjusted, the duration can be extended at lower intensity, and most issues resolve with dose modification rather than discontinuation.
The real numbers
A 2018 systematic review in the Journal of the American Academy of Dermatology reported that approximately 95 percent of isotretinoin patients experience cheilitis (lip dryness), 50 to 70 percent experience facial xerosis, and 10 to 20 percent experience eczema-like dermatitis at peak dose. All of these resolve within two to three months of treatment end. The cumulative dose target is approximately 120 to 150 mg per kg of body weight, typically delivered over four to six months of daily dosing.

FAQ
Can I exfoliate at all during Accutane? No. The skin is too fragile and the actives are unnecessary.
Should I wax during treatment? No. Waxing and threading often tear isotretinoin-treated skin. Shaving and tweezing are fine; waxing should wait until six months after the final dose.
Tool: hair removal method picker — matches the right method to hair type + budget + pain tolerance.
Can I use eye cream? A simple ceramide eye cream is fine. Avoid retinoid or vitamin C eye creams during the course.
Why are my eyes so dry? Isotretinoin reduces meibomian gland oil production, which affects the tear film. Artificial tears two to four times daily help. Some patients use omega-3 supplements as adjunct.
When can I start tretinoin? Most dermatologists wait three to four weeks after the final Accutane dose before starting a maintenance retinoid like adapalene 0.1 percent.
