Lactic Acid: The Gentle Skin Exfoliator
Discover lactic acid, the gentle AHA that exfoliates, brightens, and hydrates for a smoother, more radiant complexion. Ideal for sensitive skin.
What is it?
Lactic acid is a popular alpha hydroxy acid (AHA), a class of chemical exfoliants used in skincare. While historically derived from fermented milk, most forms in modern cosmetics are synthetic. It works by dissolving the bonds between dead cells on the skin's surface, which encourages cell turnover. A key advantage of lactic acid is its dual ability to exfoliate while also helping the skin stay hydrated. It's considered one of the mildest AHAs, making it a suitable choice for many skin types, including sensitive skin.
Why is it trending?
Lactic acid's popularity comes from its powerful results and relative gentleness. It's a multi-tasking ingredient that addresses common concerns like dullness, uneven texture, hyperpigmentation, and the appearance of fine lines. It is favored because it delivers a brighter, smoother complexion with a lower risk of irritation than other, stronger AHAs. This versatility allows it to be formulated into many products, from daily serums to weekly peels, making it an accessible ingredient for a wide range of skincare routines and goals.
How does it affect people?
Regular use of lactic acid can lead to a visibly brighter, smoother, and more even-toned complexion. It helps to unclog pores and can improve skin firmness over time. For many, it's a gentle introduction to chemical exfoliation. However, some may experience mild side effects like tingling or redness when first using it. Crucially, all AHAs increase the skin's sensitivity to the sun, so applying a broad-spectrum sunscreen daily is essential. Users should start with lower concentrations and avoid using it on the same days as other potent ingredients like retinol to prevent irritation.
