Chemical Peel Aftercare: A Day-by-Day Guide to Peeling, Redness and Healing

The short version

Expect tightness and redness on day one, the first flaking around day two or three, peak peeling on days three to five, and skin back to normal by day seven. Do not pick, do not exfoliate, do not use active ingredients, and do not skip sunscreen. A superficial peel resolves in three to five days; a medium-depth peel takes seven to ten.

Day 1: tight, red and slightly shiny

Your skin will feel taut, look flushed and have a faint sheen. Some warmth is normal. There is no visible flaking yet — the acid has broken the bonds between dead cells, but they have not started shedding.

Do: rinse with lukewarm water and a bland non-foaming cleanser. Apply a fragrance-free moisturiser as often as it feels tight. Sunscreen if you go outside at all. Don’t: exercise hard, use hot water, or apply anything containing acids, retinol or vitamin C.

Heat is the theme of what to avoid — hot showers, saunas, intense workouts and steam all raise inflammation in freshly treated skin.

Day 2: the tightness peaks

Skin often feels tightest on day two. It may look slightly darker or bronzed in places, particularly where the acid was applied more heavily. That bronzing is normal and precedes shedding.

Fine flaking may begin around the nose and mouth, because those areas move most.

Do: keep moisturising. Sleep on a clean pillowcase. Don’t: help it along. Pulling a flake that is not ready lifts living tissue with it, and that is how peels cause the marks they were meant to treat.

Days 3–5: peak peeling

This is the phase that generates the anxious searches. Skin sheds in sheets or flakes, unevenly, and it looks worse before it looks better. New skin underneath appears pink and shiny.

The unevenness is normal — the face does not shed on a synchronised schedule. Areas with thinner skin or more movement go first.

Do: moisturise generously; hydrated flakes release more cleanly. If a flake is hanging loose and already detached, you can trim it with clean scissors. Keep hands off everything else. Don’t: shave over peeling areas, use a washcloth or cleansing brush, swim in chlorinated water, or wax anywhere on the face.

Not everyone peels visibly, and that does not mean nothing happened. Light peels frequently work with only microscopic shedding.

Days 5–7: back to baseline

Most flaking is done. Skin looks brighter and feels smooth, though it may still be slightly pink and more sensitive than usual for another week.

Do: reintroduce actives gradually — one product every few days, starting with the mildest. Vitamin C first, retinoids last, and only once no pinkness or tenderness remains. Don’t: book another exfoliating treatment immediately. Give a superficial peel two to four weeks and a medium peel four to six.

What not to do after a chemical peel: the full list

•           No picking or peeling by hand — the single biggest cause of post-peel pigmentation and scarring

•           No retinoids, AHAs, BHAs, benzoyl peroxide or vitamin C until skin is fully settled

•           No physical scrubs, brushes or exfoliating cloths

•           No waxing, threading or laser hair removal on treated areas for two weeks

•           No saunas, steam rooms, hot yoga or intense cardio for 48–72 hours

•           No direct sun, and no tanning of any kind, for two weeks minimum

•           No makeup for the first 24 hours, and mineral formulas after that

Sunscreen is not optional, in any month

Fresh post-peel skin has lost its outer protective layer and has less defence against UV. Unprotected exposure at this stage is a reliable way to trigger hyperpigmentation — and to undo the pigment work a peel was often done for in the first place.

This applies through a London winter too. UV comes through cloud, and snow reflects a meaningful share of it back up at your face. Broad-spectrum SPF 30 or higher, every morning, reapplied if you are outdoors for long. On deeper skin tones, a mineral or tinted formula with iron oxides adds protection against visible light, which also drives pigment.

When to call your provider

Most of what alarms people is normal. These are not:

•           Blistering, or any area that weeps

•           Spreading redness with heat and swelling after day three, which can indicate infection

•           Yellow crusting

•           Cold sore outbreaks — peels can trigger reactivation in people with a history

•           Pain that increases rather than decreases after day two

Call rather than wait. Early intervention is what prevents a complication from becoming a scar.

Is it purging or a reaction?

Small spots appearing in the week after a peel are common and usually purging — accelerated turnover pushing existing congestion to the surface, in areas where you already break out. A reaction shows up in new areas and gets worse rather than better. The full diagnostic checklist is here.

How many peels, and how often?

A single peel gives a visible refresh. Meaningful change to pigmentation, texture or acne generally takes a course of four to six, spaced two to four weeks apart for superficial peels. Deeper peels are spaced further and used more sparingly. Where peels sit relative to other exfoliation methods is covered in our comparison of peels, microdermabrasion and hydradermabrasion.

Frequently asked questions

Is peeling after a chemical peel normal? Yes — and so is not peeling. Visible shedding depends on the acid, its strength and your skin. Neither indicates success or failure.

How long does a chemical peel take to heal? Three to five days for a superficial peel, seven to ten for a medium-depth one.

Can I wear makeup after a chemical peel? Wait 24 hours, then use mineral makeup. Avoid heavy or long-wear formulas until flaking has finished.

Can I exercise after a peel? Light walking is fine. Skip anything that raises body heat or produces heavy sweat for 48–72 hours.
