What's in one but not the other
The two labels share 8 of the 60 ingredients between them. The actives are where they part company.
What each one adds acts on The living epidermis, The stratum corneum for CeraVe Resurfacing Retinol Serum and The stratum corneum, Not established for Medik8 Liquid Peptides. That is the layer each is understood to act on, not how deep it travels.

Medik8 Liquid Peptides is a different bottle only for: glycerin, pro-vitamin b5, palmitoyl tripeptide-1, argireline, matrixyl synthe'6.
Which keeps longer
a pump and one light-sensitive active: the packaging is doing work here.
where this comes from
The pack form is read off the packshot; the light-sensitive actives are the base's photostability rows, sourced on each glossary page; the period after opening is not read yet. Catalogue checked September 2026.
a dropper bottle and nothing on this label that light breaks; the period after opening not read yet.
Medik8 Liquid Peptides is the one to keep if you use it slowly: a dropper bottle, nothing on this label that light breaks.
Where each label stops telling you the dose
Ingredients are listed in order of how much is inside, but only down to 1%. Below that the brand may list them in any order it likes, so the bottom of a label is a set, not a ranking. These two stop being a ranking in very different places.

Below the line is not too little to work: ceramides, retinoids and peptides all act far under a percent. It means the position stops carrying information. Where the line falls is inferred from the first ingredient whose whole job is done at a fraction of a percent, so it is a close read of the label rather than a number from the formula sheet.

Can I use CeraVe Resurfacing Retinol Serum and Medik8 Liquid Peptides together?

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. CeraVe Resurfacing Retinol Serum is placed by Niacinamide (the living epidermis), Ceramide 3 (the stratum corneum), Retinol (the living epidermis). Medik8 Liquid Peptides is placed by Glycerin (the stratum corneum), Hyaluronic acid (the stratum corneum), Pro-vitamin B5 (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.
