About this product

Product description

A lightweight, first-step serum that helps bring skin back into balance. This water-like formula is infused with six targeted peptides that work together to smooth fine lines, minimize the look of pores, and improve texture and tone for visibly clearer, firmer-looking skin. Each peptide supports specific skin needs—helping to boost elasticity, refine uneven texture, balance oil, calm redness, and strengthen the moisture barrier. The toner-like texture absorbs quickly without stickiness, delivering lightweight hydration and preparing skin to better absorb the rest of your routine. With daily use, skin feels smoother, looks brighter, and appears more refined over time. 150 mL/5.07 fl. oz.
