- **High-strength exfoliation**: Combines 30% AHA (glycolic + lactic acids) to target surface texture and brighten skin, with 2% BHA (salicylic acid) to unclog pores and smooth bumps.
- **Rinse-off treatment**: Applied for up to 10 minutes (no longer) to avoid irritation, then washed off – not a leave-on serum.
- **Not for beginners or sensitive skin**: Can cause stinging, redness, or peeling; requires sun protection and should be used 1–2 times per week max.
