Many clients report seeing visible skin refinement and an even, radiant skin tone after just one treatment. The smooth results and... hydration may last 5 to 7 days or even longer. Because skin is ever-changing and its cells turn over every 28 days, we recommend investing in monthly or quarterly HydraFacial treatments if your goal is to improve the appearance of fine lines, wrinkles, brown spots, oily, and congested skin. Continued HydraFacial treatments are highly recommended to maintain skin health results.
