BHA + PHA
BHA + PHA — a combination of oil-soluble beta-hydroxy acid with the milder, water-binding polyhydroxy acids. BHA works inside pores to clear congestion, while PHAs gently exfoliate the surface and help retain moisture. This pairing suits those who want pore benefits with a lower risk of the dryness sometimes linked to stronger acids.
Key points
- BHA, typically salicylic acid, is oil-soluble and effective at clearing pore-clogging sebum and debris.
- PHAs offer gentle surface exfoliation and humectant properties that help limit dryness.
- This pairing can appeal to oily or blemish-prone skin that is also sensitive.
- PHAs' larger molecules make them less likely to trigger stinging than smaller acids.
- Consistent sunscreen use helps protect freshly exfoliated skin.
Frequently asked
Can you use BHA and PHA together?
Yes, combining BHA and PHA can offer pore-clearing benefits alongside gentle surface exfoliation and added hydration. It is often positioned as a milder option for skin that finds stronger acid combinations irritating.
Is BHA and PHA suitable for oily, sensitive skin?
This combination can work well for oily skin that is also reactive, since BHA targets pores while PHA exfoliates gently and helps retain moisture. Start with lower frequency and adjust based on tolerance.
