Lactic acid is a good pick if your goal is smoother skin. It's both a chemical exfoliant and a moisturiser, really targeting skin texture issues. In higher concentrations, it penetrates right down into the deeper layers of your skin to clear out bacteria. For you, that means fewer breakouts and wrinkles along with firmer, more youthful skin.
Lactic acid is an alpha hydroxy acid (AHA) found in the body, often associated with exercise. It forms when our bodies break down carbohydrates for energy when oxygen levels are low. Outside our bodies, it's derived from bacteria in fermented dairy products like yogurt.
Anyone tackling breakouts or skin texture issues. It's even proven to reduce acne lesions so it wins the day for those with acne. Don't use it with other acids and exfoliants.
