Short answer: Cleveland Clinic says glycolic acid should be used at night because it increases sensitivity to the sun. The American Academy of Dermatology advises applying moisturizer immediately after exfoliating, so our routine order puts the glycolic acid step after cleansing and before moisturizer. Rinse-off or leave-on depends on the product: the American Academy of Dermatology describes at-home chemical exfoliants as applied for about 30 seconds and rinsed with lukewarm water, while Medical News Today says leave-on formulas give the acid more time to work. Cleveland Clinic advises starting once or twice a week and working up to nightly use only if your skin tolerates it. The next morning, the FDA advises sun protection while using AHAs and for a week afterwards and Cleveland Clinic advises SPF 30 or higher; our house line is SPF 30+ (see our glycolic acid and sun exposure guide).
You bought a glycolic acid product. Now what? This page sets out the routine order we suggest, and says for each step whether a source supports it or whether it is our own reading. Where the sources are silent, we say so.
The sources we leaned on most are Cleveland Clinic, the American Academy of Dermatology, the FDA and DermNet NZ.
Start With Clean, Dry Skin (Our Routine Order)
The routine order here is cleanse, rinse and pat dry before the glycolic acid step. We found no source that compares damp and dry application, so this is standard routine order, not a sourced claim about absorption. The American Academy of Dermatology describes at-home chemical exfoliants as applied for about 30 seconds and rinsed well with lukewarm, not hot, water, and says never to exfoliate over open cuts or wounds or sunburned skin.
Where Glycolic Acid Fits in Your Routine (Layering Order)
The order below is our own routine order, not a sourced rule. We found no source that gives a layering order for glycolic acid steps or a waiting time between them.
PM Routine (When You Should Use Glycolic Acid)
1
Cleanser
A gentle cleanser to remove makeup, SPF and debris. If your cleanser contains glycolic acid, this is your active step; skip step 2 and go on to step 3 after rinsing. Our suggestion, not a sourced rule.
2
Glycolic Acid (Toner or Serum)
Apply as the label directs. No source we read gives a number of minutes to wait before the next step; our practical reading is to go by feel, so once your skin no longer feels wet or tacky it is ready for the next layer. Our guide to application timing covers what we did and did not find.
3
Hydrating Serum (Optional)
Cleveland Clinic says glycolic acid helps with the absorption of other products, such as hyaluronic acid. DermNet NZ (nicotinamide) describes niacinamide as well tolerated and anti-inflammatory, and Tanno et al. 2000 found it increased ceramide synthesis and decreased water loss in dry skin. No source we read tests either with glycolic acid in one routine, so treat this step as optional and our suggestion. Our glycolic acid vs niacinamide guide sets out what is known.
4
Moisturizer
The American Academy of Dermatology says exfoliating can be drying and advises applying moisturizer immediately after exfoliating.
AM Routine (Glycolic Acid's Day Off)
1
Gentle Cleanser
Cleveland Clinic says glycolic acid should be used at night. A simple cleanser in the morning follows that advice; this is our suggestion for the rest of the AM routine.
2
Vitamin C Serum (Optional)
Cleveland Clinic says that when you are first starting out you may want to avoid using glycolic acid with vitamin C serums. Splitting vitamin C and glycolic acid across AM and PM is our suggestion. On timing, a 2013 review of vitamin C in dermatology says topical vitamin C is best used after exposure to UV light rather than before. Our glycolic acid vs vitamin C guide covers what the sources say.
3
Moisturizer
The American Academy of Dermatology says exfoliating can be drying, so a moisturizer in the morning is a sensible habit; the morning-after sensitivity to dryness is not something we found measured.
4
Sunscreen SPF 30+
The FDA says AHAs may increase sun sensitivity and advises sun protection while using them and for a week afterwards. Cleveland Clinic advises broad-spectrum sunscreen of SPF 30 or higher during the day, reapplied every two hours. Our house line is SPF 30+. See our glycolic acid and sun exposure guide.
Important: If you use a glycolic acid cleanser in the morning, apply SPF 30+ sunscreen as the final step. Cleveland Clinic says glycolic acid should be used at night; the FDA says to use sun protection while using AHAs.
Fitting Frequency Into This Routine
Cleveland Clinic advises starting once or twice a week and working up to nightly use if your skin tolerates it. Medical News Today says leave-on formulas give the acid more time to work, so a rinse-off cleanser and a leave-on toner are not the same exposure. For the full format-by-format discussion, see our complete guide to how often to use glycolic acid.
Important: Do not use two different glycolic acid products in the same routine. No source we read tests it, and Cleveland Clinic and Medical News Today both say overdoing it leads to irritation. Pick one format per evening.
What to Mix With Glycolic Acid (and What to Avoid)
Cleveland Clinic says that when you are first starting out you may want to avoid using glycolic acid with other exfoliants such as lactic and salicylic acids, retinol and vitamin C serums, so that you can isolate what is causing an issue if your skin reacts. DermNet NZ says leave-on AHA products can be alternated with retinoid creams and vitamin C, and Cleveland Clinic's retinol page suggests alternating days or glycolic acid in the morning and retinol at night. For the full pairing-by-pairing breakdown, see our complete guide to layering glycolic acid with other actives.
Our suggestion for starting out: on glycolic acid nights, keep the rest of the routine to cleanser, glycolic acid, moisturizer and, if you like, a hydrating serum, and save other actives for other nights.
The Best Products to Build Your Routine Around
These are three formats at different points in a routine; the format descriptions come from the product listings in our database, not from a dermatology source. (If you are building a body routine instead, see our best glycolic acid lotions guide, or our scalp-specific guide.)
A cleanser: rinse-off format
L'Oreal Paris Revitalift 3.5% Pure Glycolic Acid Brightening Cleanser lists 3.5% glycolic acid. It is a rinse-off product, and Medical News Today notes that leave-on formulas give the acid more time to work. No pH is published for it in our database, so we do not give a free acid figure.
A toner: leave-on format
✓ Glycolic acid verified
The Ordinary Glycolic Acid 7% Exfoliating Toner
Glycolic acid: 7%
The Ordinary Glycolic Acid 7% Exfoliating Toner lists 7% glycolic acid, a published pH of 3.5 to 3.9 and a size of 8.1 fl oz (240 ml). By our arithmetic (label percentage ÷ (1 + 10^(pH − 3.83))), that is roughly 3.2% to 4.8% free acid. It is a leave-on toner of the kind Medical News Today describes as giving the acid more time to work. Follow the label's directions; Cleveland Clinic advises starting once or twice a week.
A lower-percentage toner

Good Molecules Glycolic Exfoliating Toner
Glycolic acid: 3.5%
Good Molecules Glycolic Exfoliating Toner lists 3.5% glycolic acid; no pH is published for it in our database, so we do not give a free acid figure. If you have sensitive skin, Cleveland Clinic lists sensitive skin, dry skin, rosacea, eczema and active skin infections as reasons for caution. See our sensitive skin guide.
Sample Weekly Schedules
These three schedules are our suggestions, not studied schedules. They build on Cleveland Clinic's advice to start once or twice a week and work up, and on the alternating-days approach in Cleveland Clinic's retinol page.
Schedule A: Beginner or Sensitive Skin (2 Nights/Week)
| Day | PM Routine |
|---|---|
| Monday | Cleanser → Glycolic toner → Moisturizer |
| Tuesday | Cleanser → Hydrating serum → Moisturizer |
| Wednesday | Cleanser → Hydrating serum → Moisturizer |
| Thursday | Cleanser → Glycolic toner → Moisturizer |
| Friday | Cleanser → Hydrating serum → Moisturizer |
| Saturday | Cleanser → Hydrating serum → Moisturizer |
| Sunday | Cleanser → Hydrating serum → Moisturizer |
Schedule B: Regular User (3 Nights/Week + Retinol)
| Day | PM Routine |
|---|---|
| Monday | Cleanser → Glycolic toner → Moisturizer |
| Tuesday | Cleanser → Retinol → Moisturizer |
| Wednesday | Cleanser → Glycolic toner → Moisturizer |
| Thursday | Cleanser → Retinol → Moisturizer |
| Friday | Cleanser → Glycolic toner → Moisturizer |
| Saturday | Cleanser → Hydrating serum → Moisturizer |
| Sunday | Cleanser → Hydrating serum → Moisturizer |
Cleveland Clinic's retinol page says alternating glycolic acid and retinol might work well but that both can irritate, and Healthline's article on glycolic acid and retinol says to introduce retinol slowly, once a week to start. A beginner to retinol would start below this schedule.
Schedule C: Experienced User (4+ Nights/Week)
| Day | PM Routine |
|---|---|
| Monday | Cleanser → Glycolic toner → Moisturizer |
| Tuesday | Cleanser → Glycolic toner → Moisturizer |
| Wednesday | Cleanser → Retinol → Moisturizer |
| Thursday | Cleanser → Glycolic toner → Moisturizer |
| Friday | Cleanser → Glycolic toner → Moisturizer |
| Saturday | Cleanser → Retinol → Moisturizer |
| Sunday | Cleanser → Hydrating serum → Moisturizer (rest night) |
Healthline's over-exfoliation article quotes a dermatologist who says skin should generally be exfoliated only one to two times a week, so four or more glycolic acid nights is above that guidance and only for people who tolerate it. Every schedule assumes a morning routine of cleanser, optional vitamin C serum, moisturizer and SPF 30+.
Results Timeline: What to Expect and When
We found no source with a week-by-week timeline, so the timeline below is limited to what the sources say.
First weeks
Adjustment
A 2015 manufacturer-run study of a four-product regimen (up to 8% AHAs plus vitamins; 52 volunteers; 21 days) found mild tingling reported by just over a quarter of volunteers on day 7, decreasing with continued use. Healthline's skin purging article quotes dermatologists saying purging, which shows up where you usually break out, should be over within four to six weeks of starting a new product, and to consult a dermatologist if it lasts longer.
About 3 weeks
Texture
Healthline cites a 2015 study reporting that 9 out of 10 volunteers using AHAs over three weeks saw significant improvement in skin texture. That study was the manufacturer-run regimen trial above, relied on a self-assessment questionnaire, and did not test a single glycolic acid product.
From about week 4
Tone and pigmentation
Houshmand 2021 tested an emulsion with 10% glycolic acid and 2% phytic acid for 12 weeks in American women with Fitzpatrick skin types II to VI and reported improvement in hyperpigmentation, texture and tone from week 4 (abstract; number of participants and a control group not reported). Cleveland Clinic says over-the-counter products may take several months before pigmentation looks more even.
Several months
Fine lines
Cleveland Clinic lists collagen stimulation and an improved appearance of fine lines among glycolic acid's effects. Healthline says AHAs work for surface lines and wrinkles only, not deeper wrinkles. We found no source giving a number of weeks for fine lines.
For a detailed look at what to expect, see our before and after timeline guide.
Common Routine Mistakes (and How to Fix Them)
Mistake #1: Skipping moisturizer. The American Academy of Dermatology says exfoliating can be drying and advises applying moisturizer immediately afterwards, and warns that over-exfoliating can leave skin red and irritated.
Mistake #2: Using glycolic acid and retinol together without a plan. Healthline's article on glycolic acid and retinol says you generally will not want to mix them directly and suggests different times of day or different days. Cleveland Clinic's retinol page suggests alternating days, or glycolic acid in the morning and retinol at night. Our glycolic acid vs retinol guide goes through the sources in detail.
Mistake #3: Doubling up glycolic products. We found no source testing two glycolic products in one routine. Medical News Today lists too-frequent use and too-high concentrations among the causes of irritation, so we suggest one glycolic product per evening.
Mistake #4: Applying SPF only when it is sunny. The FDA reports that, in its studies, AHA application increased volunteers' sensitivity to UV-induced reddening by 18% after four weeks, and that the difference was no longer significant one week after stopping. It advises sun protection while using AHAs and for a week afterwards. Cleveland Clinic advises SPF 30 or higher during the day. We found no source about cloud or window UV, so we make no claim there. See our glycolic acid and sun exposure guide.
Mistake #5: Starting at full frequency. Cleveland Clinic advises starting once or twice a week and working up, and Healthline reports that Cleveland Clinic recommends every other day to begin, then daily as skin adjusts. We found no source giving a number of weeks to build tolerance, or a set rate of increase.
If you are dealing with actual irritation, see our guide to glycolic acid side effects. Healthline's over-exfoliation article says over-exfoliation shows as redness, inflammation and peeling, and that you should stop exfoliating until skin has healed.
Frequently Asked Questions
Should you use glycolic acid in the morning or at night?
At night. Cleveland Clinic says glycolic acid should be used at night because, like retinol, it increases sensitivity to the sun, and DermNet NZ says leave-on AHA preparations are best applied at night. If you do use a glycolic acid product in the morning, the FDA advises sun protection while using AHAs, and Cleveland Clinic advises broad-spectrum sunscreen of SPF 30 or higher during the day. Our house line is SPF 30+. Our how to use glycolic acid guide covers timing by format.
Where does glycolic acid go in your routine: before or after cleanser, toner, serum and moisturizer?
No source we read gives a layering order for cleanser, toner, serum and moisturizer, so the order on this page is our own: cleanser, then the glycolic acid step, then an optional hydrating serum, then moisturizer. If your cleanser is the glycolic acid product, it is the active step and you go straight on to the next layer. Two points are sourced: the American Academy of Dermatology advises applying moisturizer immediately after exfoliating, and Cleveland Clinic says glycolic acid helps with the absorption of other products, with hyaluronic acid as its example. Pairings with other actives are in our layering guide.
Should you use glycolic acid before or after a shower?
We found no source that addresses shower timing, so we make no claim either way. What the sources do describe is the rinse-off pattern: the American Academy of Dermatology describes at-home chemical exfoliants as applied for about 30 seconds and rinsed well with lukewarm, not hot, water. The order we use is cleanse, rinse and pat dry, then the glycolic acid step, which is our routine order and not a sourced rule. Body products used in the shower are covered in our body and underarms guide.
Should glycolic acid go on dry or damp skin, and how long should you wait before the next step?
We found no source that compares damp and dry application, and none that gives a number of minutes to wait before the next step, so we give neither. Our routine order is to cleanse, rinse and pat dry first. The American Academy of Dermatology advises applying moisturizer immediately after exfoliating. Our own practical reading, not a sourced rule, is that a leave-on toner or serum should no longer feel wet or tacky before you layer on top.
Do you leave glycolic acid on or rinse it off?
It depends on the product. For rinse-off products, the American Academy of Dermatology describes at-home chemical exfoliants as applied for about 30 seconds and rinsed well with lukewarm water; that is general exfoliant guidance, so check your label. Leave-on toners and serums are not rinsed, and Medical News Today says leave-on formulas give the acid more time to work and that if you get burning you should wash the product off. Peel pads vary, so follow the product's directions. Format-by-format detail is in our how to use glycolic acid guide.
How many nights a week should you use glycolic acid, and what goes on the other nights?
Cleveland Clinic advises starting once or twice a week and working up to nightly use only if your skin tolerates it. Healthline's over-exfoliation article quotes a dermatologist who says skin should generally be exfoliated only one to two times per week. On the other nights, Schedule A on this page uses cleanser, a hydrating serum and moisturizer; that is our suggestion, not a studied schedule. Cleveland Clinic also says that when you are first starting out you may want to avoid using glycolic acid with other exfoliants, retinol and vitamin C serums, so we keep other actives for other nights. See our guide to how often to use glycolic acid.
Is the glycolic acid routine the same on your body (arms, legs, underarms)?
We found no source that sets a routine for the arms, legs or underarms, so we do not say it is the same. The American Academy of Dermatology describes about 30 seconds of contact, a lukewarm rinse and moisturizer straight afterwards for at-home exfoliation in general, not for the face specifically. Body areas, products and schedules are in our body and underarms guide.
What should you do the morning after using glycolic acid?
Apply sunscreen. Cleveland Clinic advises broad-spectrum sunscreen of SPF 30 or higher during the day, reapplied every two hours. The FDA advises sun protection while using AHAs and for a week afterwards; in its studies, AHA application increased volunteers' sensitivity to UV-induced reddening by 18 percent after four weeks, and the difference was no longer significant one week after stopping. Our house line is SPF 30+. See our glycolic acid and sun exposure guide.
