HydraFacial first applies Activ-4 serum to remove dead skin cells. Next, Glysal serum, a chemical peel of glycolic and salicyclic acids, is applied to further exfoliate and stimulate collagen. HydraFacial’s third step involves Vortex-Extraction, a patented, painless suctioning which cleans out pores. Last but not least, HydraFacial infuses the skin with Vortex-Fusion, a serum designed to nourish and protect the skin with antioxidants, peptides, and hyaluronic acid.
