Beta hydroxy acids (BHAs)
Beta Hydroxy Acids Are Essential for Deep Pore Care
Beta hydroxy acids, or BHAs, are oil-soluble exfoliants that can penetrate deep into the pores. This makes them especially effective for oily, acne-prone, or congested skin, where they help dissolve excess sebum and clear away trapped debris.
BHAs also have anti-inflammatory and antibacterial properties, which can reduce redness and calm active breakouts. Unlike AHAs, they work both on the skin’s surface and inside pores, making them a dual-action exfoliant.
Most common BHA used in skincare:
- Salicylic Acid – typically derived from willow bark or wintergreen leaves, or made synthetically for consistency.
Other BHAs, like betaine salicylate, are sometimes used in gentler formulas, but salicylic acid remains the gold standard.
Where are BHAs derived from?
- Willow bark (Salix species)
- Wintergreen leaves
- Sweet birch bark
- Synthetic production for purity and stability
Bottom line: BHAs are the go-to exfoliants for oily and acne-prone skin, working deep inside pores to keep them clear, something AHAs can’t do.
