LIFTACTIV SUPREME SERUM 10

Shares sodium hyaluronate and peg-60 hydrogenated castor oil with Vichy, giving similar hydration delivery, but skips the dimethicone/dimethiconol silicone base and the acrylate/carrageenan firming polymers that give Vichy its plumping skin-feel.

Both have sodium hyaluronate and a silicone-forward, gel-like texture, but Vichy's signature is its dimethiconol/peg-60 castor oil emulsion system plus the polyacrylate/carrageenan film-formers for firmness, none of which this serum replicates in kind or concentration.

Shares the peg/ppg/polybutylene glycol-8/5/3 glycerin and dimethicone/acrylate crosspolymer base tech, but lacks sodium hyaluronate entirely and is built around glycation-fighting actives (HPT, ectoin) rather than Vichy's firming/hydrating complex.

Shares dimethicone/dimethiconol silicone base and acrylates/C10-30 crosspolymer, giving a similar silky skin-feel, but has no hyaluronic acid and centers on niacinamide instead, so the hydration/actives story differs.

Matches on sodium hyaluronate as the star ingredient, but is a pure hydration serum with no silicones, no firming polymers, and no peg-60 castor oil, so it feels and performs quite differently from Vichy's richer, film-forming formula.
