pH Level
Highly acidic — effective for exfoliation. Avoid layering with alkaline products.
Dermatologist Note
Salicylic acid is oil-soluble, allowing it to penetrate into pores and dissolve the sebum plugs that cause blackheads and breakouts — unlike AHAs which only work on the surface. The pH of ~3.4 ensures the salicylic acid remains in its active, un-ionized form. Widely regarded by dermatologists as the gold standard OTC acne treatment for comedonal acne.
Based on published clinical literature and dermatological research.
Patch Test Recommended
This product contains high-strength actives. Before full application, apply a small amount to your inner arm or jaw and wait 24 hours to check for irritation.
If you experience redness, burning, or itching — discontinue use and consult a dermatologist.
