Benefits of lactic acid

Key benefits of lactic acid in skincare include:

Exfoliation: Lactic acid is an effective chemical exfoliant. When applied to the skin, it helps to remove dead skin cells from the surface, revealing smoother and fresher skin underneath.
Moisturisation: Unlike some other exfoliants, lactic acid also has humectant properties, which means it can attract and retain moisture. This helps keep the skin hydrated while exfoliating.
Hyperpigmentation: Lactic acid can help fade dark spots, sunspots, and other forms of hyperpigmentation, leading to a more even skin tone.
Fine Lines and Wrinkles: It can improve the appearance of fine lines and wrinkles by promoting skin cell turnover and stimulating collagen production.
Acne Treatment: Lactic acid can help treat acne by exfoliating the skin and preventing clogged pores. It is particularly suitable for individuals with sensitive or acne-prone skin.
Gentle Exfoliation: Lactic acid is considered a milder exfoliant compared to some other AHAs, making it a good option for those with sensitive skin.
