And if you keep both?

Most people reading a comparison are choosing. If you already own both, the question is a different one, and it has an answer.

These clash.

Retinoids and exfoliants both speed up cell turnover, so together they tend to stack irritation and can wear down your barrier.

Use them on alternate nights rather than the same evening.

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. Celimax The Vita A Retinal Shot Tightening Booster is placed by Glycerin (the stratum corneum), Niacinamide (the living epidermis), Retinal (the living epidermis). 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.
