This cult-favorite, popular BHA exfoliant is often called the gold standard in skincare communities. It’s gentle enough for daily use but strong enough to clear blackheads and smooth skin texture.

This formula contains 2% salicylic acid, a beta hydroxy acid that dives deep into your pores to unclog oil, remove dead cells, and reduce blackheads. It also includes Green Tea Extract, which helps calm redness and protect your skin barrier.

Key Ingredients:

2% Salicylic Acid – unclogs pores and removes dead skin cells
Green Tea Extract – soothes redness and protects the skin
Methylpropanediol – enhances absorption

According to board-certified dermatologist Dr. Whitney Bowe,

“Paula’s Choice 2% BHA is one of the most balanced salicylic acid exfoliants out there. It’s effective enough to treat congestion but gentle enough for daily use, even on sensitive skin.”
