This BHA serum contains 2% Salicylic Acid which means it can penetrate deeper into your skin, helping to unclog pores. BHA products can help fight blackheads and breakouts and reduce pore appearance. BHA serum is a great choice for oilier skin as its anti-inflammatory and anti-bacterial properties can help calm breakout prone skin without any burning or tingling sensation. Thanks to added 1% Hyaluronic Acid, our BHA serum is non-drying to skin.
