What's in one but not the other
The two labels share 8 of the 75 ingredients between them. The actives are where they part company.
What each one adds acts on The stratum corneum, The living epidermis for Anua Niacinamide 10% + TXA 4% Serum and The living epidermis, The dermis, The stratum corneum for Celimax The Vita A Retinal Shot Tightening Booster. That is the layer each is understood to act on, not how deep it travels.
Only in Anua Niacinamide 10% + TXA 4% Serum
Only in Celimax The Vita A Retinal Shot Tightening Booster
Celimax The Vita A Retinal Shot Tightening Booster is a different bottle only for: retinal, vitamin c (laa), pro-vitamin b5, caprylic/capric triglyceride.
Which keeps longer
a dropper bottle and nothing on this label that light breaks; the period after opening not read yet.
a tube and two light-sensitive actives: 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 (not printed) is read off the maker's page, never a reseller's. Catalogue checked September 2026.
Anua Niacinamide 10% + TXA 4% Serum 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.

17 of 32 sit below the line, marked by Carbomer. Including what it is sold on: Retinal.
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.

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. Anua Niacinamide 10% + TXA 4% Serum is placed by Glycerin (the stratum corneum), Niacinamide (the living epidermis), Ceramide 3 (the stratum corneum). Celimax The Vita A Retinal Shot Tightening Booster is placed by Glycerin (the stratum corneum), Niacinamide (the living epidermis), Retinal (the living epidermis). A layer is where an ingredient does its work, never how deep it travels, and never a claim about how well it works.
