Chemical Peel Aftercare

Keep it simple, keep it out of the sun, and do not pick. Those three things cover most of what goes wrong after a peel. Your provider’s protocol is specific to your peel depth and overrides general guidance, including this page.

What to expect, by depth

Aftercare is not one routine. What is trivial after a superficial peel is a genuine planning problem after a medium one.

SuperficialMedium
Visible peelingLight flaking, days 2 - 4Significant, days 3 - 7
MakeupOften the next dayTypically after peeling completes
Return to workSame or next dayPlan several days
Actives resumeAround a weekPer provider, longer
Sun protectionEssentialCritical

Deep peels are managed by the performing physician and follow a dedicated protocol.

The universal rules

Whatever the depth, freshly peeled skin wants to be left alone. The instinct to help it along is the source of most complications.

DoDo not
Use a gentle cleanser onlyExfoliate, physically or chemically
Use a bland moisturiserUse actives — retinoids, AHA, BHA, vitamin C
Wear broad-spectrum sunscreen dailyGet sun exposure
Let flaking shed naturallyPick, peel or pull at skin
Follow your provider’s product listIntroduce new products
Keep the skin comfortable and hydratedUse hot water or steam

Picking is the main cause of scarring

Skin that is mid-shed looks untidy, and a half-attached flake is almost designed to be pulled. Pulling skin that is not ready removes living tissue underneath, and it is the leading cause of scarring and pigmentation problems after peels.

The practical trick is to make it harder to do absent-mindedly. Keep a moisturiser within reach and apply it when you notice yourself touching your face, keep your hands busy in the evening, and accept a few untidy days. Nothing you do speeds up shedding; you can only slow it down or damage it.

Sun protection is the highest-stakes item

Freshly peeled skin is significantly more photosensitive, and sun exposure during healing raises the risk of post-inflammatory hyperpigmentation — which is far harder to resolve than it is to avoid.

  • Broad-spectrum sunscreen daily, reapplied through the day rather than applied once in the morning.
  • Physical shade where practical — a hat outdoors does more than another layer of product.
  • Avoid deliberate sun exposure entirely during the peeling phase.
  • Remember that windows and overcast days are not protection.
  • Continue past the point where the skin looks normal, particularly after a medium peel.

What to actually put on your face

The goal for the first week is boring. A routine with three items is easier to follow than one with eight, and there is nothing a serum can do during shedding that a bland moisturiser cannot do better.

StageRoutine
Days 0 - 2Gentle cleanser, bland moisturiser, sunscreen. Nothing else
Days 3 - 7Same, applied more often if skin feels tight
After peeling completesReintroduce one product at a time, several days apart
ActivesOnly when your provider says, and one at a time

Reintroducing everything at once is how people conclude a peel "ruined" their skin when what actually happened is that four actives went back on a barrier that was not ready.

See a doctor if

Most peels are uneventful. These are the signs that are not part of normal healing and warrant contacting your provider or a doctor.

  • Increasing pain rather than pain that is settling.
  • Spreading redness, warmth or swelling.
  • Pus or discharge.
  • Fever.
  • Blistering beyond what your provider described.
  • A cold sore outbreak — tell your provider beforehand if you are prone to them.

Planning the first week

After a medium peel, the awkward window is predictable enough to schedule around. Treating it as a known week rather than a surprise is most of the difference between a manageable recovery and a miserable one.

DayWhat to plan for
0 - 1Redness and tightness. Nothing social
2Skin may darken and feel tight before anything sheds
3 - 7Visible peeling. Work from home if you can
7 - 10Peeling completes, pink skin underneath
2 - 4 weeksPinkness gradually settles. Sunscreen throughout

If you have to be seen during the peeling phase, ask your provider what you can wear on your face. The answer is usually "nothing yet", and hearing that from them beats finding out from a foundation that clings to every flake.

Frequently asked questions

Q.How long until I can wear makeup?

After a superficial peel, often the next day. After a medium peel, usually once peeling has completed. Ask your provider for your specific protocol.

Q.When can I use retinol again?

Per your provider — typically around a week after a superficial peel, and longer after a medium one. Reintroduce one active at a time.

Q.Can I pick the flaking skin?

No. Pulling skin that is not ready removes living tissue underneath and is the main cause of scarring and pigmentation problems after peels.

Q.Do I really need sunscreen?

Yes. It is the single most important aftercare step, because sun exposure during healing raises the risk of hyperpigmentation.

Q.What if I get a cold sore?

Tell your provider beforehand if you are prone to them, so prophylaxis can be discussed, and contact them if one develops afterwards.
