Liftactiv Serum 10 Supreme

Shares capryloyl salicylic acid and similar occlusive/silicone texture, but swaps rhamnose/adenosine for retinyl linoleate and plant oils, a different anti-aging approach entirely.

Shares hyaluronic acid (sodium hyaluronate + hydrolyzed HA) and panthenol-type hydration, but lacks rhamnose and adenosine, which are Vichy's actual hero actives for firmness.

Shares sodium hyaluronate and a similar silicone-heavy texture (polysilicone-11, pentaerythrityl tetraethylhexanoate) but has no rhamnose or adenosine, the actives Vichy actually markets this serum on.

This is a retinol-niacinamide serum-cream; it shares only sodium hyaluronate incidentally and has none of Vichy's core actives (rhamnose, adenosine, capryloyl salicylic acid).

A hydrating oil-and-butter serum with sodium hyaluronate, but completely missing rhamnose, adenosine, and capryloyl salicylic acid that define the source's firming action.
