a tube and one light-sensitive active: the packaging is doing work here.
where this comes from

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. The Ordinary Niacinamide 10% + Zinc 1% is placed by Niacinamide (the living epidermis), Zinc PCA (not established), Pentylene Glycol (the stratum corneum). The Ordinary Vitamin C Suspension 23% + HA Spheres 2% is placed by Vitamin C (LAA) (the dermis), Squalane (the stratum corneum), Isononyl Isononanoate (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.
