The cosmetics industry has discovered a new beauty elixir for itself: lactic acid. It promises an even complexion, provides moisture and regulates the physiological pH value as a component of the skin’s own protective acid mantle.
In addition, the natural fruit acid is supposed to help against pimples, wrinkles and pigment spots. Whether as the active ingredient in a day cream, as intensive serum or as peeling – all facts about the gentle beauty booster…

Lactic acid – what is it?
Lactic acid, also called lactate, is an acid that is formed when sugar is broken down from carbohydrates and can be found as an ingredient in foods such as beer, whey and, of course, milk. Lactic acid is either produced by a fermentation processor, as is the case with cosmetic products, synthetically reproduced in the laboratory. Even if the term acid sounds like an aggressive substance, lactic acid is very gentle and even suitable for sensitive skin.
This is how cosmetics with lactic acid affect the skin:
As a gentle peeling: lactic acid belongs to the so-called alpha hydroxy acids, also called AHA acids, which have a keratolytic effect. This is more complicated than it is and translated means that lactic acid acts like a particularly gentle fruit acid peeling: it dissolves cornifications on the upper layer of the skin, cleanses the pores and ensures an even complexion – including a radiant complexion!
As a moisturizer: Lactic acid is a true moisturizer booster, it has a moisturizing effect, protects the skin from drying out and hydrates it sustainably. Lactic acid as an active ingredient in the day cream optimally supports this process – especially in winter as it binds moisture.
How lactic acid regulates pH
As already mentioned, lactic acid is part of the natural acid protective mantle of our skin. Unlike many chemical care substances, which quickly upset the slightly acidic and very sensitive pH of 4.5 to 5.5, cosmetic products with lactic acid regulate the protective mantle and thus have a positive effect on the skin flora.
Lactic acid as an anti-aging booster
The active substance lactic acid enters the cells of the skin particularly quickly, especially damaged cells are said to react to the absorbed lactic acid. They benefit from its moisturizing effect and the body’s own production of collagen is stimulated. The result is youthful, fresh-looking skin. The formation of new cells is also to be stimulated by the active ingredient – so lactic acid is not only a repair effect.
