Our 4% BHA Advanced Serum Toner delivers a double concentration of BHA (beta hydroxy acid, aka salicylic acid) to not only exfoliate your skin’s surface, but also clear deep buildup inside pores and target multiple signs of ageing.

This non-sticky, leave-on serum is formulated with two barrier-supporting MVPs: glycerin to lock in hydration and adenosine to help soothe skin and soften fine lines. With continued use, skin appears softer, smoother, and more youthful.

At a glance:

Helps visibly refine enlarged pores
Smooths rough, bumpy texture
Softens the appearance of fine lines
Has an optimal pH range of 3.6-3.9

The bottle for this full-sized product is made from 96% recycled material (excluding cap and orifice reducer).

Apply an even layer over face & neck with fingers or a cotton pad, avoiding the eye area. Leave on; do not rinse.

If you have a salicylate allergy, check with your physician before using any products that contain salicylic acid.
