Serum expert duo age

Shares the key actives gluconolactone (PHA exfoliant), sodium hyaluronate, argan oil, and tocopherol at what looks like similar formulation strength, plus near-identical base ingredients.

Shares tocopherol and citric acid only; the source's key PHA exfoliant (gluconolactone) is absent, and this product's real hero is a peptide (hexapeptide-11) not present in the source at all.

Only tocopherol overlaps; it lacks the gluconolactone (PHA) and sodium hyaluronate that are the source's main anti-aging actives, instead relying on Q10/ubiquinone as its hero ingredient.

Only trace overlap (tocopherol, citric acid); this is an oil-based multi-botanical serum with essential oils, missing the source's core gluconolactone/hyaluronic acid combo entirely.

Same story as the sister Swiss Toniq product—shares only tocopherol/citric acid, missing the gluconolactone and hyaluronic acid that define the source's efficacy.
