What are Alpha hydroxy acids?
Alpha hydroxy acids (AHAs) are a group of water-soluble acids commonly used in skincare products for their exfoliating and rejuvenating properties. They help to remove dead skin cells, improve skin texture, and promote a smoother, more radiant complexion. Here are some of the most common types of AHAs and their characteristics:
Glycolic Acid: Glycolic acid is derived from sugarcane and is the smallest molecule among AHAs. It has excellent exfoliating properties and can penetrate the skin deeply. Glycolic acid helps to promote skin cell turnover, improve skin tone and texture, and reduce the appearance of fine lines and wrinkles. It is suitable for most skin types but may be more irritating for sensitive skin.
Lactic Acid: Lactic acid is derived from milk or fermented fruits. It has a larger molecular size compared to glycolic acid, making it a gentler option. Lactic acid helps to exfoliate and hydrate the skin, improve skin tone and texture, and reduce the appearance of hyperpigmentation. It is often well-tolerated by sensitive skin.
Mandelic Acid: Mandelic acid is derived from almonds. It has larger molecules and is known for its gentle exfoliating properties. Mandelic acid helps to improve skin texture, even out skin tone, and reduce the appearance of acne scars and hyperpigmentation. It is often suitable for sensitive skin and can be a good option for those with acne-prone skin.
