Combination skin is the type most likely to get the wrong serum because most serums are built to do one thing very well. Control oil or add hydration, not both. This one understands that combination skin's needs change by zone and works with that reality. Powered by Niacinamide and Hyaluronic Acid, it works in 7 targeted ways: addresses mixed skin needs, avoids overcorrecting any area, controls oil in the zones that need it, hydrates the zones that need that instead, fades dark spots, brightens overall, strengthens your barrier, and balances skin pH. The formula absorbs evenly and lets the ingredients work where they are needed without disrupting what is already working.
