What the brand claims
In the brand’s own words, quoted as written.
“This original hyaluronic acid serum delivers deep hydration and a smoother skin appearance, formulated with four types of hyaluronic acid and pro-vitamin B5. The blend of low-, medium-, and high-molecular-weight hyaluronic acid molecules along with a next-generation HA crosspolymer supports hydration across multiple skin layers, while panthenol helps strengthen the skin barrier by supporting the production of ceramides and fatty acids.”
