Beta-hydroxy acid (BHA), also known as salicylic acid, is a type of chemical exfoliant that is commonly used in skincare products. It is derived from willow bark and has a structure that allows it to penetrate the skin more deeply than alpha-hydroxy acids (AHAs).

• Acne treatment: BHA is highly effective in treating acne by penetrating deep into the pores to unclog them and reduce inflammation.

• Oil control: BHA helps to regulate oil production, making it an ideal ingredient for those with oily skin.

• Anti-aging: BHA is an effective exfoliant that can help to reduce the appearance of fine lines and wrinkles, and improve skin texture and tone.

• Even out skin pigmentation: BHA can help to even out skin pigmentation and improve the appearance of dark spots and hyperpigmentation.

• Exfoliation: BHA is a gentle exfoliant that can help to remove dead skin cells and improve skin texture.

It is important to note that BHA can be irritating to some individuals, especially those with sensitive skin. It is recommended to start with a low concentration of BHA and gradually increase the frequency of use to allow the skin to adjust. Sunscreen is also important when using BHA, as it can increase sun sensitivity. Overall, BHA is a highly effective ingredient in treating acne and improving the overall health and appearance of the skin.
