Applying Higher Concentrations of Lactic Acid

Moving from a mild exfoliating tonic to a higher concentration lactic acid formula requires a shift in approach. Lactic acid works by dissolving the protein bonds between surface skin cells, and at stronger percentages, this process accelerates.

Correct usage relies on frequency and the condition of the moisture barrier. Consistency is secondary to the health of your skin surface, and over-application will manifest as dryness or tightness rather than the intended smoothing effect.

1. Prepare a clean surface. Cleanse your skin thoroughly to remove all debris and oils. Use lukewarm water to ensure the surface is neutral before application. Pat your face completely dry with a clean towel, as damp skin can increase the absorption rate of acids.
2. Apply to targeted areas. Dispense three to four drops onto your fingertips. Press the liquid into the skin in a smooth, continuous motion, avoiding the delicate eye area and lips. Allow the fluid to sit undisturbed until it feels slightly tacky to the touch.
3. Allow for absorption. Wait five minutes before layering any further products. This wait time ensures the acid reaches the appropriate pH level on your skin without dilution from other textures. Do not rinse the product off.
4. Seal with moisture. Follow with a simple, unscented barrier-repairing moisturizer. Focus on areas that feel tight or prone to dehydration. Using a basic cream prevents unnecessary irritation from fragrance or active complexes.
5. Check for reactions. Observe the skin for any stinging or persistent redness over the next ten minutes. If the skin feels calm, you may proceed with the rest of your evening. If you notice significant heat, remove the product immediately with cold water.

Exfoliation is an subtractive process; focus on what you remove, not just what you add.
