In ancient Egypt, Cleopatra famously bathed in milk to achieve smooth, supple skin, unknowingly benefiting from the lactic acid found in sour milk.
While applying spoiled milk may sound odd, lactic acid works effectively to soften fine lines and diminish blemishes.
We don't recommend using rotten milk, of course. Many beauty brands now incorporate lactic acid in their serums and cleansers for skin treatment.
Today, lactic acid stands out as a favored alpha hydroxy acid, widely utilized for improving skin tone, texture, and providing gentle exfoliation.

What is Lactic Acid?
Lactic acid is a beneficial skincare component commonly found in exfoliating products. It's often featured in pH-correcting formulations, whether left on the skin or as part of a rinse-off peel.
This sought-after ingredient gently loosens the connections between dead skin cells, making them easier to shed. Rinse-off peels containing lactic acid are used weekly or biweekly to effectively eliminate dead skin.
As we age, factors like sun exposure and skin conditions can slow down the natural shedding of dead skin cells, resulting in a duller complexion. Regular use of lactic acid can rejuvenate your skin, leaving it looking fresher and more youthful.
Benefits of Lactic Acid
So, how does lactic acid improve your skin?
Firstly, it possesses antibacterial properties. A 1985 study indicated that lactic acid could effectively combat skin infections, even in adults, including bacteria that cause acne.
Additionally, lactic acid promotes firmer, thicker skin, thereby reducing the appearance of wrinkles and fine lines. It also helps treat acne lesions, accelerates skin cell turnover, and enhances moisture retention.
Using Lactic Acid
If you're new to lactic acid, consider starting with a serum or toner, applying it for three nights followed by three nights off. During your break, nourish your skin with hydrating ingredients to support the new cells.
While using lactic acid or any acid-based product, avoid potent exfoliants like retinoids or scrubs.
Lactic acid encourages new skin growth, which may increase sensitivity to sunlight. Therefore, always apply a broad-spectrum SPF 30 or higher while using this ingredient to protect against sun damage.
