What the scene shows

The cross-section at the top of this page is not decoration and not a diagram of the skin in general: it places the molecules these two are sold on at the layer each is understood to act on. La Roche-Posay Hyalu B5 Suractivated Serum is placed by Glycerin (the stratum corneum), Pro-vitamin B5 (the stratum corneum), Hyaluronic acid (the stratum corneum). The Ordinary Alpha Arbutin 2% + HA is placed by Alpha Arbutin (the living epidermis), Lactic acid (the stratum corneum). A layer is where an ingredient does its work, never how deep it travels, and never a claim about how well it works.
