Adapalene
Adapalene is a prescription-strength retinoid — chemically a retinoid, clinically closer to a mild topical medication than a cosmetic ingredient. Skinzy surfaces it for education only: it requires a prescription, and using it correctly (and safely alongside anything else in a routine) is something to work out with a dermatologist, not from a schedule on a website.
How it works
A highly stable, third-generation topical retinoid that selectively binds to nuclear retinoic acid receptors RAR-beta and RAR-gamma. It targets follicular epithelial hyperkeratinization to reduce mature comedones and displays distinct modulation of cellular inflammatory pathways.
In practice, this is genuinely a different category from the rest of this list — it's the reason it's flagged for education, not a buy recommendation.
How to introduce it
Wait about 20 minutes before the next step. Judging Adapalene before week 12 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
Possible purging window: weeks 2–6 — temporary increased breakouts as turnover speeds up, not a sign to stop. A purge shows up as small whiteheads in areas you already tend to break out, and settles down on its own within that window. That's different from a bad reaction, which shows up as redness, burning, or swelling in places you don't normally break out, doesn't improve with time, and is a reason to stop — see below.
- Patch test on the inner forearm 48 hours before first facial use.
- PM only — never apply under sunscreen or in daylight.
- Sunscreen is mandatory every morning after any retinoid night, no exceptions.
- Never combine with AHA, BHA, or benzoyl peroxide in the same session.
- Do not apply to broken, sunburned, or actively irritated skin.
- Buffer with moisturizer underneath if stinging occurs — do not stop the ramp on the first uncomfortable night.
- — Stinging or redness lasting more than 60 seconds after 3+ uses.
- — Visible peeling beyond light, dry flaking.
Who should be careful
Adapalene is rated higher potency — that's exactly why it has a real ramp-up schedule above rather than a "just start using it" recommendation.
Don't combine with
Same-night use can irritate skin or cancel out the active — alternate nights instead of layering them together.

Most people see a fair result around 12 weeks of consistent use — judging earlier usually means judging too soon.
