Glycolic Acid Peels & Skincare

Many sources suggest starting slowly, around once or twice a week, and gradually increasing as your skin builds tolerance. Daily use is generally not recommended for beginners or sensitive skin, since overuse may lead to irritation or dryness.

Using glycolic acid and retinol together on the same night can be too harsh for many people and may cause irritation. It is often recommended to alternate them on different nights instead, and to introduce each one gradually.

Glycolic acid is typically suggested for nighttime use because it can increase the skin's sensitivity to the sun. Applying a broad-spectrum SPF 30 or higher each morning is widely recommended while using it.

People with sensitive skin may still be able to use glycolic acid, but lower concentrations and less frequent use are often suggested. A patch test first can help you see how your skin responds, and a dermatologist can advise if you have an ongoing skin condition.

Research suggests over-the-counter formulas in roughly the 7 to 17 percent range can support smoother texture and a brighter look, with one study noting improvement in skin texture and fine lines from an 8 percent solution. Many sources suggest keeping at-home AHA products at or below about 15 percent, while higher-strength professional peels are performed in-clinic by trained providers.
