Glycolic acid or retinol for rough skin texture?

What is the difference?

Retinol is one member of the retinoid family, not another name for prescription tretinoin. Retinol comes in creams, lotions and serums, so the bottle shape is not a qualification. Choose by the active and its directions rather than the packaging.26

How do you start retinol?

1. 1Try a little on a small area first. Wait a couple of days and check for redness or itching before using it more widely.
2. 2At bedtime, wash with a gentle cleanser and pat dry. Do not scrub.
3. 3Apply a thin layer, using about a pea sized amount for the face. Keep it away from your eyes, nose and mouth. Start every other night, following the package directions.
4. 4Finish with a moisturizer labeled noncomedogenic, meaning formulated not to clog pores.
5. 5Use sunscreen during the day, along with shade and protective clothing.

How should you use glycolic acid?

Use the amount and frequency specified for your particular product or treatment plan. A professional glycolic peel is not interchangeable with a daily skincare product. Peel intensity depends on concentration, pH, application time and formulation, and peels require controlled application and neutralization. Do not copy a clinic peel schedule for a home product.17

If roughness is mainly dryness and scaling, moisturizer directly addresses both. Apply it immediately after bathing and repeat as needed. Acidic preparations can sting on scratched or cracked skin, so adding an exfoliant is not the first move for those areas.3

What if the roughness is small bumps?

Blackheads and whiteheads are clogged follicles, also called comedones. Both glycolic acid and topical retinoids are options for this pattern of acne. Significant improvement can take several months; persistent or unresponsive comedonal acne warrants a dermatologist visit.5

Small rough bumps on the outer arms, thighs or buttocks can be keratosis pilaris, a harmless condition involving plugs of keratin in hair follicles. Glycolic acid and retinoids are both treatment options, but there is no clear winner for everyone. Moisturizer is part of treatment, especially for dryness. If a treatment plan has not helped after 4 to 6 weeks, tell your dermatologist. Keeping the bumps controlled usually requires maintenance rather than a permanent cure.47

Who should be careful?

Do not use retinoids during pregnancy. Retinoids are a poor starting choice for skin with allergies, substantial dryness, redness or inflammation. Irritation can trigger dark marks in darker skin. For keratosis pilaris treatment, pause exfoliating medicine for a few days if dryness or irritation develops. Moderate or severe acne scarring needs a dermatologist's assessment rather than another texture product.27

Expect visible retinol improvements to take several weeks, with fine line changes taking several months. Early dryness, peeling or burning are possible side effects, not signs that you need a stronger product.6
