How to use

After cleansing, apply at the toner or essence step and let it absorb fully before the next product. Start 2 to 3 times a week and increase gradually based on how skin responds. Use sunscreen if applied in the daytime.

Pros
  • Betaine salicylate, a BHA from willow bark, for clogged pores and blackheads
  • Niacinamide for oil control and the look of marks
  • Panthenol and hyaluronate to help offset dryness
Cons
  • Betaine salicylate has far less clinical evidence than salicylic acid, and its strength is not disclosed
  • Can irritate sensitive skin; the brand says to build up use gradually
  • The brand says not to combine it with other acids, retinol or vitamin C, or to use AHAs and BHAs while pregnant or breastfeeding
