Salicylic acid is an excellent chemical exfoliator. It's oil-soluble, allowing it to penetrate pores and dissolve dead skin cells, making it particularly effective for acne-prone and oily skin.

Consult with a doctor or dermatologist before using salicylic acid during pregnancy. While topical use may pose a low risk, alternative exfoliants may be recommended for safety.

Salicylic acid can potentially irritate eczema-prone skin. Due to its exfoliating properties, it might disrupt the skin barrier, worsening dryness and inflammation. Proceed with caution and consult a dermatologist.

2% salicylic acid is generally considered safe for daily use for many, but it depends on individual skin sensitivity. Start with less frequent application (2-3 times per week) and gradually increase as tolerated to avoid irritation or dryness.
