In depth
What it does
The potassium salt of lactic acid, used as a humectant and pH buffer, part of the skin's natural moisturizing factor complex. As an humectant ingredient, it is particularly valued for natural-moisturizing-factor humectant and buffers and adjusts formula ph.
Skin type guide
Works across all skin types, but is especially beneficial for dry and dehydrated skin. Oily skin types also benefit — proper hydration helps regulate sebum production.
How to use it
Apply to slightly damp skin to maximise moisture retention — humectants work by drawing water to the skin, so they need a water source to pull from. Use early in your routine, before heavier creams or oils.
