How to Exfoliate Your Face: Acids, Scrubs, How Often and Who Should Wait

How to exfoliate your face comes down to one gentle method chosen for your skin type, one session at first, moisturizer straight afterwards and sunscreen every morning. The American Academy of Dermatology (AAD) names two kinds of exfoliation, physical (a washcloth, brush or scrub) and chemical (alpha and beta hydroxy acids), and says dry, sensitive or acne-prone skin may do better with the milder choices. Skip it on sunburned or broken skin. Stinging, swelling or redness that does not settle is a question for a doctor, not a stronger product.

Physical or Chemical: The Two Kinds of Exfoliation

The AAD’s guide to exfoliating safely at home defines it as “the process of removing dead skin cells from the outer layer of your skin.” Mechanical exfoliation “uses a tool, such as a brush, pad, or sponge, or a scrub to physically remove dead skin cells.” Chemical exfoliation “uses chemicals, such as alpha and beta hydroxy acids, to dissolve dead skin cells.”

A 2018 review of alpha-hydroxy acids in the journal Molecules explains the chemical route: AHAs loosen the cohesion between the dead cells at the surface so they shed. Its authors add that whether an AHA helps or harms skin “depends on its concentration,” that high concentrations can cause irritation or peeling, and that reported side effects include redness, swelling, burning and itching.

Professional peels are chemical exfoliation at a higher strength, applied by a trained person. Our herbal peel for rough, dull skin uses plant-based actives instead of strong synthetic acids. At home, you are choosing among the milder products below.

How to Exfoliate Your Face for Your Skin Type

The AAD sorts the choice by skin type. People with dry, sensitive or acne-prone skin “may prefer just a washcloth and a mild chemical exfoliator,” while those with oily, thicker skin “may want to use stronger chemical treatments or mechanical exfoliation.” It also says to avoid strong chemical or mechanical exfoliation if you have a darker skin tone, because aggressive exfoliation can leave more dark spots.

Pick one row. A cloth, a scrub and an acid in the same week are three rounds of exfoliation. The same reasoning applies below the neck, and our guide to exfoliating your back covers tools and technique for that skin.

How Often, and What Saigon Changes

The AAD gives no weekly number. It ties frequency to your skin type and method: “Generally, the more aggressive the exfoliation, the less often it needs to be done.” A washcloth sits at one end, a coarse scrub or a stronger acid at the other. Start with one session a week and add a second only if your skin stays calm.

Heat changes the picture. Our guide to skincare in Saigon’s climate says humidity slows the shedding of surface cells, which tempts people to escalate, and that over-exfoliating “damages the barrier and produces more oil and more irritation rather than less.” Its weekly routine puts gentle exfoliation at about twice a week, chemical rather than physical on the face. It adds that skin congested in the rainy months can turn tight and flaky in the dry ones, so recheck your routine when the season turns.

If dullness is what sent you to the scrub, our article on why skin looks dull lists eight causes, and dead skin is only one.

What Not to Use on the Same Night

The AAD warns about prescription retinoid creams and products containing retinol or benzoyl peroxide: exfoliating while using them “may worsen dry skin or even cause acne breakouts.” Its page on testing skin care products adds that ingredients such as retinol and glycolic acid “can irritate your skin.” If a doctor prescribed a retinoid or isotretinoin, ask before exfoliating at all.

For two exfoliants, such as a scrub and an acid, the AAD sets no rule. Treat each as another round of exfoliation, which by its logic means longer gaps. Add one new product at a time, so you know which one caused a reaction.

A Gentle First Month, One Product at a Time

1. Week 1: change nothing about exfoliating. Cleanse gently, moisturize, and wear sunscreen every morning. Note how your skin feels, so you can tell later what changed.
2. Week 2: choose one product from the table and test it first. The AAD’s method is a quarter-sized spot where it will not be rubbed or washed away, the normal amount, twice a day for seven to 10 days.
3. If the spot turns red, itchy or swollen: wash the product off gently, do not use it again, and soothe the spot with a cool compress or petroleum jelly, as the AAD advises. A reaction those do not relieve belongs with a dermatologist.
4. End of week 3: if the spot stayed clear, use the product once, on a clean face. For a scrub, use small circular motions for about 30 seconds; for a brush or sponge, short light strokes; then rinse with lukewarm, not hot, water. For a leave-on acid, follow the label.
5. Straight afterwards: moisturize. The AAD says exfoliating “can be drying to the skin” and advises moisturizer “immediately after exfoliating.”
6. The next morning: check for stinging, tightness or redness, then put on sunscreen. If any of them appear, skip to the reset below.
7. Week 4: if your skin stayed calm, repeat once. Add a second weekly session later, only if it stays calm, and start no other new product until the month is over.

Signs You Are Exfoliating Too Much, and the Reset

The AAD’s warning is short: over-exfoliating “could lead to skin that is red and irritated.” Cleveland Clinic’s guide to a damaged skin barrier gives the wider picture: stinging, especially when you apply products; dry, scaly or flaky skin; rough patches; itching; tenderness; inflammation; and acne. Dermatologist Melissa Piliang, MD, names over-exfoliating or scrubbing among the habits that can break the barrier down.

The reset is plain. Stop the exfoliant and anything else that stings. Wash with a mild, soap-free, fragrance-free cleanser and warm water, because hot water washes away natural oils. Moisturize with a product that contains ceramides, fatty acids and lipids, and wear sunscreen every day. Cleveland Clinic says it typically takes three or four months to start seeing the benefits of this gentle routine, so be patient. If you use prescribed acne treatments, ask your dermatologist before backing off them.

See a doctor sooner if the skin burns, swells, hurts or looks infected, or if it is getting worse instead of better. Cleveland Clinic lists infection among the signs of a damaged barrier. If your face is also flaking, our article on why a face starts peeling sorts the causes and says when to see a doctor.

Who Should Wait Before Exfoliating

• Sunburn or open skin. The AAD is blunt: “Never exfoliate if you have open cuts or wounds or if your skin is sunburned.”
• Eczema, rosacea or psoriasis. Cleveland Clinic lists them among the conditions linked to a poor skin barrier. Ask a dermatologist before you add an exfoliant.
• Isotretinoin or prescription retinoids. Ask the prescriber first. Spa peels ask the same question before booking.
• Darker skin tones, or dark spots after breakouts. The AAD says to avoid strong exfoliation of either kind.

What Exfoliating at Home Cannot Do

Pigment. Exfoliation does not lighten dark spots, and the AAD’s warning points the other way: aggressive exfoliation can add them. Our Dermaquest page says “pigmentation is a sun-driven condition,” so daily sunscreen decides whether any result holds, and that no facial removes melasma for good.

Scars. Pitted or indented scars are, in our acne peel page’s words, “textural damage below the surface.” A scrub does not reach it. That needs collagen-building work or a dermatologist.

Deep congestion. If the problem is small bumps that keep coming back rather than a dull surface, our article on closed comedones sets out what they are and when to see a dermatologist. Severe or persistent acne, and any prescription option, is a doctor’s decision.

Where a Spa Fits When Home Exfoliation Is Not Enough

A spa visit makes sense when the basics are in order and a problem remains. Each page below says who should not book, so read it first.

Texture and dullness. The Herbal Skin Renew Peel for texture and dullness takes 60 minutes and costs 550,000 ₫. Its page describes plant-based actives that speed up cell turnover, released more gradually than a strong acid, so it suits sensitive skin that needs renewing. Wait if you have a recent sunburn, cold sores, eczema or broken skin in the area, or take isotretinoin or prescription retinoids, and tell your aesthetician if you are pregnant. Afterwards the page asks for 24 hours with no makeup, sweating or swimming, nothing acidic or retinoid, then sunscreen every morning.

Congested skin. The Intensive Acne Clear Chemical Peel for congestion and post-breakout marks is 60 minutes for 500,000 ₫, a professional acid blend matched to your skin’s tolerance. Its page says it does not treat severe cystic acne and does not remove pitted scarring. Tell the team first if you are pregnant or breastfeeding or have taken isotretinoin or prescription retinoids; the page says a waiting period applies to retinoids.

Dehydrated, sensitive skin. Glass Skin Therapy for hydration with gentle exfoliation is also 60 minutes, at 350,000 ₫. Its page calls it well suited to sensitive skin because it is hydration-led, not acid-led, and sends active breakouts to Acne Care Treatment first.

Dark spots. The Dermaquest Signature White brightening facial runs 60 minutes for 500,000 ₫. Its page says sunscreen “is the treatment”: without it, the pigment returns, often darker. Tell the team if you are pregnant or use prescription skincare.

Our facial treatments menu in District 1 compares all of them. If a question is not answered on a page, ask when booking.

Exfoliating Your Face Without Overdoing It

A good routine is small: one method chosen for your skin type, one new product at a time, moisturizer straight afterwards and sunscreen every morning. Let the AAD’s rule set the pace, because the more aggressive the method, the less often. If your skin stings, reddens or tightens, stop and reset. Sunburned, broken or reactive skin waits for a doctor’s advice, and marks, scars and deep congestion are not jobs for a scrub.
