Most people start buying skincare before they understand what their skin actually needs. That's why so many routines fail: the wrong order, the wrong actives, the wrong assumption that more products equals better skin. Skincare 101 fixes that.
This category is the entry point for everyone — whether you're 19 and just figured out moisturizer is non-negotiable, or 38 and rebuilding your routine from scratch after a barrier flare. The articles here give you the working knowledge that turns skincare from a confusing aisle into a small set of decisions you can make confidently.
Long-form, plain-English explainers covering skin anatomy and biology, the four common skin types and how to identify yours, the science of the skin barrier and pH, an introduction to the skin microbiome (the field that's reshaping skincare in 2026), the actual order to apply skincare products, and how to read an INCI label without falling for marketing.
Skincare is built on a small handful of truths. Your barrier is non-negotiable. Sunscreen prevents more aging than every anti-aging product combined. Cell turnover slows with age, and that's the lever almost every active ingredient pulls on. Once you understand these, the difference between a product that helps and a product that just costs money becomes obvious.
True beginners, returners after a long break, and anyone who feels they've been guessing at skincare for years. If you've ever wondered which order things go in, or whether your skin type actually changed when you turned 30, you're in the right place.
