What is lactic acid? What are its effects on the skin?

Lactic acid is available in higher concentrations for medical-grade use as well. Lactic acid possesses antioxidant properties, acts as a chemical exfoliant, and what we love about it is that it also hydrates the skin.

Here's how lactic acid is used in skincare: Lactic acid belongs to the group of AHA (alpha hydroxy acid) acids and has several beneficial properties. It acts as an antioxidant, chemical exfoliant, and promotes skin hydration. AHA acids can be categorized into two main groups: organic and inorganic. These groups can further be divided into exfoliating and humectant acids, depending on their concentration or percentage. Some AHA acids include glycolic acid, lactic acid, malic acid, mandelic acid, tartaric acid, and citric acid. All these acids aid in the exfoliation of the skin's surface. Products containing lactic acid for at-home use are usually mild and contain concentrations of up to 10%. Products with higher concentrations, around 10-15%, require professional application. If you've never used a chemical exfoliant before, starting with lactic acid is perfect as it's gentle, making it an excellent choice for sensitive skin. However, it's important not to start directly with a 10% concentration; instead, opt for a lower percentage product.

Chemical exfoliants containing AHA, such as lactic acid, remove the top layer of dead skin cells. It's essential to highlight that lactic acid only dissolves dead skin cells, never affecting healthy skin. It gently removes dead skin cells from the skin's surface without causing damage or injury.

Here are the effects of using lactic acid on the skin: Lactic acid, produced in a laboratory setting, is used in skincare products. These naturally exfoliating acids help reduce aging-related wrinkles. Lactic acid formed during glycogen metabolism has a protective effect.

Improvement in skin texture and tone Enhancement of skin appearance or firmness Reduction in dark spots (though if this is your concern and you've never exfoliated before, it's a great starting point, but not the primary spot-fading acid) Smoothing out fine lines and surface wrinkles Boosting hydration
