Alpha Hydroxy Acid (AHA) is a group of naturally occurring acids found in various fruits and milk. Common types include glycolic acid (from sugarcane), lactic acid (from milk), and citric acid (from citrus fruits). AHAs are popular in skincare for their exfoliating properties, helping to remove dead skin cells, improve skin texture, and reduce the appearance of fine lines and wrinkles.
More about Alpha Hydroxy Acid (AHA)
Alpha Hydroxy Acids (AHAs) are water-soluble acids that work to exfoliate the skin's surface, promoting cell turnover and revealing smoother, more radiant skin. They are often used in chemical peels, cleansers, and serums. Some key benefits of AHAs include improving skin texture, reducing the appearance of fine lines and wrinkles, and addressing uneven skin tone and hyperpigmentation.
When using products containing AHAs, it's important to wear sunscreen daily, as these acids can increase sun sensitivity. AHAs are suitable for most skin types, but individuals with sensitive skin should start with lower concentrations and gradually increase usage to avoid potential irritation.
- Glycolic acid: Derived from sugarcane, it has the smallest molecular size, making it effective for penetrating the skin and promoting exfoliation.
- Lactic acid: Found in milk, it is known for its hydrating and exfoliating properties, making it suitable for sensitive skin.
- Citric acid: Derived from citrus fruits, it helps to brighten the skin and enhance radiance.
