What Should You Do Before and After a Chemical Peel?

By Chasity Galjour

Most of what decides how a chemical peel goes happens outside the treatment room. The peel itself takes minutes. The weeks before it and the days after it are where people either protect their skin or set themselves up for a slow, blotchy recovery. This article walks through what the published guidance says about both ends, and where the evidence is thinner than the marketing suggests.

Why does preparation matter more than the peel itself?

A peel is a controlled injury. An acid solution removes some depth of skin, and the result depends on how that skin heals. The deeper the solution goes, the more it can change, and the more can go wrong.

A review in the Journal of Cutaneous and Aesthetic Surgery, Complications of medium depth and deep chemical peels, puts it plainly: results and complications are generally related to the depth of wounding, with deeper peels giving more marked results and a higher incidence of complications. The authors add that complications are more likely with darker skin types, certain peeling agents, and sun exposure, and that they range from minor irritation and uneven pigmentation to permanent scarring.

Two of those three risk factors, skin type and sun exposure, are things you can raise or manage before anyone opens a bottle. That is the case for taking preparation seriously.

What should you tell the provider before a peel?

The American Academy of Dermatology keeps a short page on preparing for a chemical peel. Its list of what to disclose is specific:

• Whether you take, or have ever taken, isotretinoin for severe acne.
• Every other medicine you take or recently took, including antibiotics, acne medicines, and non-prescription products such as aspirin.
• Whether you get cold sores often, or have had them in the past.
• Whether your skin scars easily.
• All herbs, vitamins, and minerals, even ones you stopped a while ago.
• Every surgery and cosmetic treatment you have had.

The same page says not to leave anything out, even if it seems unimportant. People tend to skip the supplements and the earlier cosmetic work, usually out of embarrassment. Those are exactly the items the list calls out.

What questions are worth asking at the consultation?

The AAD preparation page also lists questions for the patient to ask. The useful ones are the uncomfortable ones: how many peels the person has performed on people with your skin coloring, what you will need to do before and after, what side effects are possible, whether you carry a higher risk for any complication, and whether there will be downtime.

It also notes that a consultation can end with a different treatment being suggested instead. A consultation that can only end in a peel is a sales appointment.

Do you need a skin care plan in the weeks before?

Sometimes. The AAD's chemical peel FAQ says some patients need to follow a pre-peel skin care plan for 2 to 4 weeks, and that this plan can improve results and reduce potential side effects. It leaves the decision to the treating dermatologist rather than prescribing one routine for everyone.

That is a reason to book the consultation well ahead of the date you want the peel, not the same afternoon.

What does recovery look like at each depth?

The AAD FAQ gives a table of what to expect. In summary:

• Light ("refreshing" or "lunchtime") peel: healing takes 1 to 7 days. Skin is red, and scaling may follow for 3 to 7 days. Care is lotion or cream until healed, then daily sunscreen. Makeup is usually fine right away or the next day. Three to five peels may be needed, repeated every 2 to 5 weeks.
• Medium peel: healing takes 7 to 14 days. Skin is red and swollen, and swelling worsens for 48 hours. Blisters can form and break. Care involves daily soaks, ointment after each soak, an antiviral medication for 10 to 14 days, and total sun avoidance until healed. Camouflage makeup can be worn after 5 to 7 days. A follow-up visit is required.
• Deep peel: healing takes 14 to 21 days, with the area bandaged. Care involves 4 to 6 soaks a day, ointment for 14 days, then thick moisturizer, an antiviral medication, and total sun avoidance for 3 to 6 months. The AAD says a deep peel is done in a surgical setting, and that a person can have only one.

Those ranges are worth comparing against your calendar before you commit. A medium peel is not something to schedule the week before an event.

What should you avoid while the skin heals?

The AAD FAQ is direct about what raises the risk of infection or scarring: failing to protect the skin from the sun, failing to care for the wound as instructed, scratching the treated skin or picking off a scab, applying makeup before the skin heals, and using a tanning bed or other indoor tanning.

It also explains the moisturizer instruction, which people often treat as optional. If the skin dries and cracks, it can scar. And if the skin burns, itches, or swells, the advice is to contact the dermatologist rather than wait it out.

Is the risk different for darker skin tones?

Yes, and there is some data on how much. A retrospective study in the Journal of the American Academy of Dermatology, Assessing the safety of superficial chemical peels in darker skin, reviewed 473 superficial peel treatments in patients with Fitzpatrick skin types III to VI over five years at one center. Eighteen treatments, or 3.8 percent, were associated with complications. The most frequent were crusting (2.3 percent), postinflammatory hyperpigmentation (1.9 percent), and redness (1.9 percent). All side effects resolved within 8 months.

Two details from that study are practical. Skin type VI was associated with higher odds of side effects, and side effects were less common in winter. The authors list the single-center, retrospective design as a limitation, so the numbers describe one clinic's patients rather than everyone.

The AAD FAQ makes a related point: people with skin of color can safely have a peel, but they should see a dermatologist with a track record of treating darker skin tones, because pigment problems can otherwise be permanent.

How long do results last?

The AAD FAQ says most results are not permanent, because skin continues to age. It adds that sunscreen every day after healing helps maintain what the peel achieved. Light and medium peels can be repeated on a schedule the dermatologist sets.

If you want more background on the peel types themselves, the overview of chemical peels already on this site covers the solutions and what each is used for.

Frequently asked questions

• Can I wear makeup right after a peel? It depends on depth. The AAD says usually immediately or the next day after a light peel, after 5 to 7 days for a medium peel, and at least 14 days for a deep peel.
• Why would I be given an antiviral medication? The AAD lists an antiviral for 10 to 14 days as part of care after medium and deep peels, and asks patients to disclose any history of cold sores beforehand.
• Is winter a better time for a peel? In the 2018 study of superficial peels in skin types III to VI, side effects were less frequent in winter. That is one retrospective study, so treat it as a hint rather than a rule.
• How many light peels will I need? The AAD says 3 to 5 may be necessary, repeated every 2 to 5 weeks.
• What is the single most common mistake during recovery? The sources do not rank them, but sun exposure appears in both the AAD's list of risks and the journal review's list of complication factors.
