BHA – Effects & Uses of Salicylic Acid

What is BHA?

BHA stands for beta-hydroxy acid , usually salicylic acid. It's a fat-soluble acid that can penetrate deep into pores and dissolve excess sebum and dead skin cells. This makes BHA ideal for treating blemished, oily, and acne-prone skin.

How does BHA affect the skin?

• Pore ​​cleansing: BHA penetrates the pores and removes blockages.
• Exfoliation: Gently removes dead skin cells and refines the skin’s appearance.
• Anti-inflammatory: Salicylic acid has a soothing effect and can reduce redness.
• Smoothing: Regular use leads to a more even skin texture.

Application of BHA

BHA is used in toners, serums, and peels. Start with low concentrations (0.5–2%) and gradually increase according to tolerance. Apply in the evening and always use sunscreen during the day. For sensitive skin, initially use only 1–2 times a week.

Who is BHA suitable for?

Especially suitable for oily, combination, and blackhead-prone skin . Test cautiously on dry, sensitive skin. For acne sufferers, BHA can be a useful supplement in consultation with a dermatologist.

Conclusion

BHA is an effective, scientifically proven ingredient for clear and refined skin. Luxury formulations often combine BHA with hydrating and soothing ingredients to achieve maximum effectiveness with the highest tolerability.
