Chemical Peel Aftercare: Build a Simple Barrier Routine

A practical post-peel routine built around a gentle cleanser, a bland moisturizer, and sunscreen — plus decision rules for what to add, what to skip, and when to stop.
Quick answer
Keep the first week after a peel to three products: a gentle, non-foaming cleanser, a bland fragrance-free moisturizer, and a mineral sunscreen you will actually reapply. Add nothing else — no acids, no retinoids, no scrubs, no vitamin C — until flaking has fully stopped and your skin feels normal for two or three days. If you are shopping before your peel, buy those three basics first; everything else is optional.
The three-product rule for the first seven days
Post-peel skin is temporarily less able to hold water and defend itself, so the goal is not to treat anything — it is to stop interfering. A short routine also makes it obvious what is helping and what is stinging. Cleanse once at night with lukewarm water and your fingertips; in the morning, rinse with water alone unless you are visibly oily or sweaty. Pat, do not rub, and apply moisturizer within about a minute while skin is still slightly damp.
Reapply moisturizer as often as skin feels tight, not on a fixed schedule. Tightness, not dryness, is the signal that the barrier needs another layer. If a product stings for more than a few seconds, that is a stop signal, not a sign it is working.
- Morning: water rinse, moisturizer, sunscreen.
- Evening: gentle cleanser, moisturizer.
- Any time: extra moisturizer over tight or flaking areas.
- Nothing else until flaking has stopped for two to three days.
What to avoid after a chemical peel, and for how long
The usual mistake is restarting actives too early because skin looks calm. Peeling can continue for several days after a professional-strength peel, and the skin underneath is newer and more reactive than it looks. Hold exfoliating acids, retinoids, benzoyl peroxide, scrubs, cleansing brushes, and at-home peel pads until peeling has completely finished and skin has felt normal for two to three days. Then reintroduce one product at a time, every few days, starting at half your usual frequency.
Also skip hot showers, saunas, steam rooms, and vigorous exercise that leaves you sweating heavily during the flaking phase, since heat and friction make irritation worse. Waxing, threading, and shaving over treated areas should wait until the skin is fully settled.
Sunscreen is the step most people get wrong
Freshly exfoliated skin is more vulnerable to sun exposure, and sun damage can undo the evenness a peel was meant to improve. Use a broad-spectrum sunscreen every morning, reapplied every two hours outdoors, and treat a hat and shade as part of the routine rather than an extra. Mineral formulas are often better tolerated during the flaking phase because they tend to sting less, but the one you will reapply is the right one.
If you cannot reapply during a workday, at least apply generously before you leave and again as soon as you are back indoors.
How to choose products when your skin is mid-flake
Buy for tolerance, not for results. Look for short ingredient lists, no fragrance or essential oils, and no alcohol denat high on the list. Creams and ointments hold water better than lotions during flaking; gels and foaming washes tend to be the most stripping. If you already own a moisturizer that has never stung your face, that is a better choice than a new one bought mid-peel, because a reaction to a new product is hard to interpret when skin is already irritated.
One practical exception: if you are planning a series of peels, buy your aftercare before the first one so you are not improvising on day two.
Decision rules for your post-peel shelf
- If skin is stinging, burning, or red beyond mild pinkness: Stop all products except plain water rinsing and a bland moisturizer, and contact the professional who performed the peel. Do not try to soothe it with a new active or a mask. Pain is a stop signal, not a stage to push through.
- If flaking has stopped but skin still feels tight: Keep the three-product routine and add moisturizer applications rather than adding a new product. Tightness usually resolves before reactivity does. Wait two to three normal-feeling days before reintroducing anything.
- If you want to restart exfoliating acids or retinoids: Reintroduce one product at a time at roughly half your previous frequency, spaced a few days apart, and stop if irritation returns. Do not restart two actives in the same week. One change at a time is the only way to know what caused a reaction.
- If you are choosing between a buffered and unbuffered peel: Buffered 35% glycolic is the more forgiving option; unbuffered 35% is described for experienced users. Higher strength is not better aftercare planning — it just means a longer no-active window. Match the peel to your experience, then plan aftercare around it.
Products that fit this routine
- LACTIC Acid Skin Chemical Peel 70%: LACTIC Acid Skin Chemical Peel 70% is a professional-strength peel containing 70% lactic acid, described as supporting smoother, softer-looking skin and a more even-looking tone. This is a treatment, not aftercare — it belongs on your calendar, not in your barrier routine. Plan your gentle cleanser, moisturizer, and sunscreen purchases before you use it, so you are not shopping while your skin is flaking.
- GLYCOLIC ACID 35% BUFFERED PEEL - Advanced Cosmetic Grade: GLYCOLIC ACID 35% BUFFERED PEEL is described as a professional-strength 35% buffered glycolic acid peel that exfoliates gently for smoother-looking texture and a brighter, more even tone. Buffered means the acid is partially neutralized, which is generally the more forgiving option if you are newer to peels. Either way, the aftercare rules above are the same: three basics, no actives until flaking stops.
- GLYCOLIC ACID 35% UNBUFFERED PEEL - Advanced Cosmetic Grade: GLYCOLIC ACID 35% UNBUFFERED PEEL is described as a professional-strength 35% unbuffered glycolic acid peel for experienced users, for visibly refined texture and brighter-looking tone. Unbuffered is the stronger-feeling version of the same strength, so treat your post-peel window as longer, not shorter. If you are deciding between the two, the buffered version is the safer starting point.
Who this routine fits
Best for
- Anyone in the first week after a professional-strength peel such as lactic 70% or glycolic 35%
- Shoppers who want a short, low-risk product list before their first peel
- People whose skin stings easily and who need to identify which product is the culprit
Not for
- Anyone with blistering, spreading redness, or severe pain, who should contact a clinician rather than adjust products
- People looking for a post-peel brightening or anti-aging serum — that step comes later, once the barrier has settled
- Anyone wanting to keep exfoliating during the flaking phase
