A Four-Week Plan for Lactic Acid

Lactic acid functions by dissolving the intercellular glue that holds dull, dead cells to the skin surface. Unlike mechanical scrubs, which provide a physical friction that can be unpredictable, liquid exfoliants offer a uniform application. This protocol focuses on establishing a steady rhythm to improve surface texture over the course of one month.

The primary objective is consistency rather than intensity. Accelerating the process by increasing frequency will lead to compromised barriers rather than smooth skin.

1. Begin the introductory phase. Cleanse your face and ensure it is entirely dry before application. Apply two to three drops of a five percent lactic acid solution to the fingertips and press onto the skin. Allow the product to absorb for ten minutes before applying a simple, fragrance-free moisturizer. Repeat only once during this week.
2. Establish a consistent cadence. If no irritation occurred during the first week, increase application to twice weekly. Space these applications at least three days apart to allow the skin time to recover. Maintain the same application method, ensuring the skin remains hydrated with a basic moisturizer afterward.
3. Finalize the frequency. Increase usage to every other evening, alternating with a night off. The goal is to reach a stable state where the product is effective without causing redness or tightness. If you notice any signs of sensitivity, revert to the week two cadence immediately.
4. Observe and refine. By week four, the skin should be accustomed to the regimen. Continue with the every-other-evening frequency unless the skin indicates it needs more recovery time. Use this week to evaluate the overall texture and determine if the current concentration is appropriate.

Consistency provides better results than high concentration or excessive frequency.
