Can I use an exfoliating cleanser and an acid serum?

Which acid is in your serum?

Glycolic, lactic and salicylic acid exfoliate; hyaluronic acid hydrates, so a hyaluronic acid serum is a different case. Vitamin C, also called ascorbic acid, has a different main job as an antioxidant, but combining it with chemical exfoliants can still cause problems.12

A cleanser containing exfoliating acids counts as chemical exfoliation. A cleanser with scrub particles provides mechanical exfoliation, meaning it physically removes dead skin cells. An exfoliating cleanser already counts as exfoliation, even if the bottle files it under face washing.34

How should I use them?

Use this as a general routine, rather than treating two exfoliating products as a required pair. Keep the routine simple, rather than giving every bottle a speaking role.2

1. 1Choose one exfoliating product for that routine. If you choose the acid serum, start with a gentle cleanser. If you choose the exfoliating cleanser, leave out the exfoliating serum.
2. 2Cleanse gently with your hands and rinse. Do not add a separate scrub or exfoliating tool to the cleansing step.
3. 3On serum days, apply the serum after cleansing and before moisturizer. For glycolic acid, start once or twice a week at night and increase only if your skin is not irritated.
4. 4Apply moisturizer after exfoliating. Use moisturizer morning and evening because exfoliating products can dry your skin.
5. 5Finish your morning routine with SPF 30 or higher sunscreen every day. Facial acids can make skin more vulnerable to sun damage.

Does using them at different times solve the problem?

Separating the products is a way to simplify each application, not a reason to exfoliate more often. The right frequency depends on your skin and how aggressive the exfoliation is: stronger exfoliation generally needs to happen less often. Count both products when considering how much exfoliation your routine contains, rather than counting only the serum.34

What results should I expect?

Exfoliating acids can improve smoothness and uneven color. Salicylic acid helps unclog pores, while lactic acid is a gentler option for rough texture. Glycolic acid is a stronger exfoliant that can help with discoloration and fine lines. Results take time and regular use; there is no single timetable for an unspecified cleanser and serum.1

Who should be more careful?

Dry, sensitive or acne prone skin can find mechanical exfoliation too irritating; a mild chemical exfoliator is a more suitable option. Avoid aggressive exfoliation if you have darker skin or develop dark marks after skin injuries, because irritation can increase pigmentation. Prescription retinoids, retinol and benzoyl peroxide can already cause sensitivity or peeling, and adding exfoliation can worsen dryness or breakouts.34

When should I stop?

Stop the irritating product if you develop redness, irritation or a rash, and make an appointment with a dermatologist. Do not exfoliate sunburned skin or areas with open cuts or wounds. If you are unsure whether exfoliation suits your skin, a dermatologist can help you choose an appropriate method.234
