Using Lactic Acid for Dry Skin

Dry skin often requires a two-pronged approach to maintain a smooth, comfortable surface. Lactic acid functions as both an alpha-hydroxy acid for mild surface exfoliation and a humectant that helps pull water toward the skin. This dual utility makes it a standard choice for those seeking to remove dull, flaky layers without causing unnecessary irritation.

This guide focuses on the mechanical application of over-the-counter lactic acid serums. By establishing a consistent, low-frequency schedule, you allow the acid to improve surface texture while preserving the moisture barrier.

1. Prepare a clean surface. Begin with a gentle, non-stripping cleanser. Do not use an abrasive cloth or manual scrub immediately before application. Pat your face until it is merely damp, as this can improve the absorption of the serum.
2. Measure the serum. Dispense a pea-sized amount onto clean fingertips. Avoid using a cotton pad, which tends to absorb too much product. Apply the liquid in thin, even strokes across the forehead, cheeks, and chin.
3. Allow for complete absorption. Wait for the serum to set completely before applying a moisturizer. If the skin remains tacky, provide it with more time. This period ensures the acid has finished its initial interaction with the surface cells.
4. Seal with hydration. Follow with a fragrance-free, occlusive moisturizer to lock in the hydration benefit of the lactic acid. This step is non-negotiable for dry skin. Ensure the moisturizer covers the areas where the serum was applied.

Lactic acid bridges the gap between removing debris and retaining essential surface hydration.
