A Guide to Lactic Acid Exfoliation

Dullness often stems from an accumulation of surface debris that prevents light reflection. Lactic acid, an alpha hydroxy acid derived from fermentation, functions by loosening the bonds between these superficial cells. Because it possesses a larger molecular size than other acids, it penetrates at a slower, more controlled rate.

This measured pace makes it an appropriate choice for those seeking surface refinement without the irritation associated with more aggressive chemical agents. Consistency and correct concentration are the primary variables for success.

1. Cleanse the surface. Begin with a neutral, non-stripping cleanser. Remove all remnants of SPF and ambient pollutants. Pat the skin dry with a clean cloth to ensure no residual moisture remains to dilute the product.
2. Apply the solution. Dispense a small amount of lactic acid onto a cotton round or directly into your palms. Press the liquid into the skin of the face and neck using a light, tapping motion. Avoid the immediate orbital area to prevent potential migration.
3. Wait for absorption. Allow the acid to remain undisturbed on the skin for five minutes. This waiting period is critical for the acid to perform its function before subsequent layers are applied. Do not rinse the product off.
4. Seal with moisture. Apply a basic, fragrance-free moisturizer. This provides a necessary barrier to maintain hydration levels. Focus on areas that feel tight or prone to dryness.
5. Morning protection. The morning after application, ensure the use of a broad-spectrum mineral SPF. Exfoliated skin is more susceptible to environmental stressors. Consistent protection maintains the results achieved overnight.

Efficiency in exfoliation is determined by regularity rather than intensity.
