Preparing for a chemical peel means getting three things ready: your skin, your medical picture, and your calendar. Skin that has been primed and left alone by harsh products tolerates acid more predictably. A provider who knows your full history can pick a safer depth. And downtime that has been planned for is downtime you will not be tempted to cut short. This checklist walks through each of those, from four weeks out to the morning of your appointment.
Start With the Consultation
Preparation begins at the consultation, not at home. A provider needs to see your skin, hear your history, and match an acid and a depth to both before anything else on this list matters. Bring a list of every prescription, over the counter product, and supplement you use, and be ready to describe how your skin has reacted to exfoliation in the past.
This is also where you decide what you are treating and how deep you need to go. Superficial peels handle dullness, mild texture, and surface pigment. Medium peels do more for fine lines and stubborn discoloration but carry real downtime. Deep peels are physician procedures with weeks of supervised care. Our overview of chemical peel types and depths is a useful thing to read beforehand, and our guide to choosing a provider covers the credentials that matter.
Four Weeks Before
- Ask whether you need priming. For medium peels, and for anyone with richly pigmented skin or a history of dark marks, many providers prescribe a few weeks of preparatory topicals to calm pigment activity before treatment. This is one of the most consequential steps and it cannot be compressed into the last week.
- Stop deliberate sun exposure and tanning beds. Recently tanned skin responds unpredictably to acid and raises the risk of uneven pigment afterward. Start wearing broad spectrum SPF 30 or higher daily now if you are not already.
- Discuss isotretinoin. Providers ask about recent isotretinoin because of concerns about how the skin heals afterward. Guidance on how long to wait has evolved and differs by peel depth, so this belongs in the conversation rather than in your own calculation.
- Raise any cold sore history. If you get cold sores, tell your provider. Resurfacing can reactivate them, and many practices prescribe antiviral medication starting before the peel for treatments that include the perioral area.
- Pause electrolysis, waxing, laser hair removal, and depilatories in the treatment area, and keep them paused until your skin has fully healed afterward.
Two Weeks Before
- Stop retinoids unless told otherwise. Tretinoin, retinol, adapalene, and similar products thin the surface layer and can make a peel act deeper than intended. Some providers keep patients on a retinoid until closer to the appointment as part of priming, which is exactly why you ask rather than guess.
- Put away scrubs, cleansing brushes, and at home devices. Microdermabrasion tools, dermarolling, and gritty cleansers all count.
- Skip other resurfacing treatments. No other peels, laser, or microneedling in the weeks before, and no at home acid products. Our comparison of at home and professional peels explains why stacking them is a bad idea.
- Confirm your medication list. Photosensitizing medications, including some antibiotics and diuretics, matter here. So do blood thinners, immunosuppressants, and anything affecting wound healing.
- Ask about a test spot. A small patch test on an inconspicuous area finds an unpredictable reaction on a fingernail sized area rather than on your whole face. It is particularly worth requesting for a first peel or a deeper one.
One Week Before
- Stop exfoliating acids. Glycolic, lactic, mandelic, and salicylic acid products, plus benzoyl peroxide, come out of the routine.
- Keep the routine bland. A gentle cleanser, a fragrance free moisturizer, and sunscreen is all your skin needs this week. Do not introduce anything new.
- Do not schedule anything that irritates the area. That includes facials, extractions, and threading.
- Reschedule if your skin is not intact. An active cold sore, open acne lesion, sunburn, rash, or any broken skin in the treatment area is a reason to move the appointment. Providers would far rather move a date than peel over an infection.
- Plan your downtime honestly. A superficial peel usually means a few days of mild flaking that makeup can cover the next day. A medium peel means roughly a week of visible peeling that it is unrealistic to work through in person. Our peeling and recovery timeline lays out what each day looks like.
Timing Around Events
People routinely book a peel too close to a wedding, a photo shoot, or a trip. Build in a buffer that is longer than the peeling itself, because redness can outlast flaking and skin sometimes takes an extra week to look settled. A conservative rule is at least two weeks of margin after a superficial peel and at least a month after a medium peel. If the event is soon and you have never had a peel before, the safer choice is to wait and start a series after it. Our guide to how often to get a chemical peel can help you work backward from the date.
The Night Before and the Morning Of
- Do not use any active products the night before. No acids, no retinoid, no scrub, no mask.
- Do not shave or wax the treatment area on the day of the appointment unless your provider specifically asks you to.
- Arrive with a clean face. Skip makeup, heavy moisturizer, and sunscreen the morning of unless your provider says otherwise. Your provider will degrease the skin anyway, but clean skin makes that step gentler.
- Eat and hydrate normally, and take your usual medications unless you have been told to hold one.
- Bring the aftercare supplies home with you. A gentle cleanser, a bland fragrance free moisturizer, and a broad spectrum SPF 30 or higher sunscreen should be in the house before you need them. Buying them while your face is peeling is nobody's idea of a good afternoon.
- Arrange a ride if you are having a medium or deep peel, and confirm in advance whether you will be given medication that makes driving unsafe.
What to Tell Your Provider, Without Being Asked
Preparation fails most often at disclosure. Volunteer all of the following even if the intake form does not ask clearly: recent isotretinoin use, cold sore history, any tendency to keloid or to heal with thick scars, autoimmune conditions, pregnancy or breastfeeding, recent sun exposure or a current tan, previous reactions to peels or laser, melasma, current prescription skincare, and every supplement you take. Also say plainly how your skin tends to pigment after injury, because a history of dark marks after a scratch or a breakout is useful information about how it will behave after a peel.
Questions Worth Asking Before You Agree
- Which acid and what concentration, and what depth are you aiming for?
- Who performs the peel, and what is their training for this depth?
- How many days of visible peeling should I expect, and how many days of redness?
- What is the plan if I get a dark patch or an unexpected reaction, and how do I reach you after hours?
- Do I need priming, a test spot, or antiviral medication first?
- How many sessions do you expect, and what will the total cost be? Our cost guide gives you a benchmark to compare against.

Ready to Book?
Every item on this list should be confirmed with the person actually performing your peel, because preparation is matched to the acid and the depth you are getting. Find a qualified provider near you, then read the aftercare guide so you know what the week after looks like before you sit down in the chair.
Frequently Asked Questions
What should you not do before a chemical peel?
Avoid deliberate sun exposure and tanning beds, retinoids, exfoliating acids, benzoyl peroxide, scrubs, cleansing brushes, waxing, threading and other hair removal in the area, and any other resurfacing treatment. Do not use active products the night before, and do not proceed if you have an active cold sore, sunburn, rash or broken skin in the treatment area.
How long before a chemical peel should you stop using retinol?
Many providers ask patients to stop retinoids about one to two weeks before a peel, because they thin the surface layer and can make the acid act deeper than intended. Some keep patients on a retinoid longer as part of a priming plan. Follow the specific instruction from the provider performing your peel rather than a general rule.
Should you prime your skin before a chemical peel?
Priming with prescription topicals for several weeks beforehand is commonly used before medium peels and for anyone with richly pigmented skin or a history of dark marks, because it helps calm pigment activity before the skin is injured. Whether you need it, and which products, is a decision for your provider at the consultation.
Can you wear makeup to a chemical peel appointment?
Arrive with a clean face when you can. Skip makeup, heavy moisturizer and sunscreen the morning of the appointment unless your provider tells you otherwise. Your provider will cleanse and degrease the skin before applying the acid, and starting from clean skin makes that step gentler.
How far in advance of an event should you get a chemical peel?
Leave more margin than the peeling itself takes, because redness can outlast flaking. A conservative approach is at least two weeks of buffer after a superficial peel and at least a month after a medium peel. If the event is close and you have never had a peel before, it is safer to wait until afterward.
Do you need a patch test before a chemical peel?
A test spot on a small, inconspicuous area is a reasonable request, especially for a first peel, a deeper peel, or skin that reacts unpredictably. It lets an unusual reaction show up on a fingernail sized patch instead of across your whole face. Ask your provider whether they recommend one for your treatment.
