Beta Hydroxy Acids

1. Definition Beta Hydroxy Acids:

Beta Hydroxy Acids (BHAs) are a class of chemical compounds commonly used in skincare products for their exfoliating and anti-inflammatory properties. The most common BHA found in cosmetics is salicylic acid.

2. Use:

BHAs are used in cosmetics to exfoliate the skin by penetrating deep into the pores and breaking down the bonds between dead skin cells, allowing them to be easily removed. This helps to unclog pores, reduce acne breakouts, and improve the overall texture and appearance of the skin. BHAs are also known for their anti-inflammatory properties, making them suitable for individuals with sensitive or acne-prone skin.

3. Usage Beta Hydroxy Acids:

When using products containing BHAs, it is important to start with a lower concentration to avoid irritation, especially for those with sensitive skin. BHAs can increase skin sensitivity to the sun, so it is crucial to use sunscreen daily to protect the skin from UV damage. BHAs are typically used in the form of cleansers, toners, serums, and spot treatments, and can be incorporated into a skincare routine once or twice a day, depending on the individual's skin type and tolerance.
