How Lactic Acid Enhances Skin Hydration, Exfoliates, and Promotes a Youthful Glow

Lactic acid, a naturally occurring alpha-hydroxy acid (AHA) derived from milk and certain fruits, is widely celebrated for its ability to exfoliate the skin, improve texture, and brighten the complexion. As a mild exfoliant, it helps to gently remove dead skin cells while enhancing skin hydration and reducing the appearance of fine lines. Lactic acid is an excellent choice for those looking for a gentle but effective way to rejuvenate their skin.

Composition of Lactic Acid

Lactic acid is composed of:

• Alpha-Hydroxy Acid (AHA) – helps in exfoliating the skin and promoting cell turnover

• Naturally Derived – typically sourced from milk, fruits, and fermented sugars

• Water-Soluble – enables deep penetration into the skin for better exfoliation and hydration

Key Features of Lactic Acid

1. Gentle Exfoliation
   Lactic acid provides a mild exfoliation, removing dead skin cells to reveal smoother, brighter skin.

Limitations and Considerations

• Sun Sensitivity
  Like other AHAs, lactic acid increases the skin’s sensitivity to sunlight. It’s crucial to apply sunscreen daily to protect the skin from UV damage.
