AHA, BHA, and PHA are types of exfoliating acids commonly used in skincare products. AHA, or alpha hydroxy acids, are water-soluble and help to exfoliate the skin's surface, improve skin texture, and reduce the appearance of fine lines and wrinkles. BHA, or beta hydroxy acids, are oil-soluble and are particularly effective at unclogging pores and treating acne-prone skin. PHA, or polyhydroxy acids, are gentler than AHA and BHA and are ideal for sensitive skin types. They work by removing dead skin cells, promoting cell turnover, and improving the skin's overall appearance.
When used correctly, AHA, BHA, and PHA can help to improve the texture and tone of the skin, reduce the appearance of fine lines and wrinkles, and promote a more even skin tone. It's important to note that these acids can make the skin more sensitive to the sun, so it's essential to wear sunscreen daily when using products that contain AHA, BHA, or PHA.
Overall, incorporating AHA, BHA, or PHA into your skincare routine can be a beneficial way to improve the appearance and health of your skin. However, it's important to start slowly, particularly if you have sensitive skin, and to always patch test new products before applying them to your entire face.
