The formula also contains zinc to support its absorption, enhancing the vitamin’s antioxidant efficacy to protect the skin against dulling pollutants. Paired with hyaluronic acid and aloe vera, the elixir delivers long-lasting moisture to boost luminosity, leaving the complexion soft, supple and noticeably smooth.
