New in box Glycolic + Lactic + Pyruvic + BHA & PHA. A multi-acid blend including Glycolic Acid which is one of the most intense exfoliants of the AHA (Alpha Hydroxy Acid) family, Lactic Acid which is much gentler due to its molecule size, Pyruvic Acid which is an Alpha-Keto Acid that works as a gentle topical peeling agent, BHA or Salicylic Acid which is an oil-soluble acid that mixes with the skin’s natural oils allowing it to penetrate and unclog pores, and PHA (Polyhydroxy Acid) which also falls under the AHA family. Probiotics. These microorganisms support the healthy mechanisms in the body. They support balanced skin microbiome and help regulate acne-causing cycle while strengthening and soothing skin. Niacinamide. The active form of Niacin (also known as Vitamin B3 or Nicotinic Acid) is one of the more stable active ingredients in skincare, with a pH around neutral. Reduces the appearance of pores and fine lines, improves blemish marks, and fades uneven texture. It also improves skin barrier function and its ability to retain moisture.
