Lactic acid: the gentle AHA for sensitive and dry skin
Lactic acid has a larger molecule than glycolic acid. It penetrates the skin more slowly and evenly, which makes it milder. At the same time it has a moisture-binding effect - it's structurally related to the skin's natural moisturising factor (NMF).
In Cyspera Neutralize, lactic acid is used as a pH regulator after the Cyspera application.
Dr. med. Niels Freitag recommends lactic acid especially to customers with dry and sensitive skin who react to glycolic acid with irritation. In our skincare studio in Cologne we see good results with regular, mild use.
Related categories: Lactic acid belongs to the exfoliation category. For stronger exfoliation: glycolic acid. For pore cleansing: salicylic acid.

Frequently asked questions about lactic acid
What's the difference between lactic acid and glycolic acid?
Both are AHAs. Lactic acid has a larger molecule and penetrates more slowly - milder and better tolerated. Glycolic acid is stronger and penetrates deeper. For sensitive or dry skin, lactic acid is the better choice.
Can lactic acid help with pigment spots?
Lactic acid can influence the distribution of melanin in the upper skin layer and soften pigment spots. The effect is gentler than with glycolic acid or retinol, but better tolerated in return.
How does lactic acid work as a moisturiser?
Lactic acid is structurally related to the skin's natural moisturising factor and can bind water in the upper skin layer. That's why the skin feels softer after a lactic acid peel than after glycolic acid.
How often should you use lactic acid?
Possible daily at low concentrations. Concentrated peels once or twice a week. With sensitive skin, start with once a week.
Is lactic acid suitable for rosacea?
Better than glycolic acid, but still with caution. At a low concentration it can improve skin texture without irritating too much. During active rosacea flare-ups, avoid acids.
