What 15% BHA twice daily actually means.
Most BHA serums on the market sit at 1–2%. At that dose, you get mild exfoliation, tolerable on daily use, modest pore improvement over time. The clinical literature on BHA starts to get interesting from around 10–15%.
The problem with high-dose BHA on the skin surface is irritation. Dryness, stripping, sensitivity. Which is why most formulations stay low.
Encapsulation changes the maths. The Clarify & Renew AHA/BHA Serum, i·Active™ 23, delivers 15% encapsulated pore-clearing BHA plus 1% surface BHA for immediate action. The encapsulated portion releases gradually inside the skin across 8–12 hours, bypassing the irritation that comes from sustained surface contact.
92% of users were satisfied in clinical testing. Up to 2 in 3 saw clearer, more even skin in two weeks or less.
AM and PM. All skin types. Those new to exfoliants may want to begin with once-daily use before progressing to twice daily.
