A solid moisturizer, but the “peptide” story does more marketing than heavy lifting.

READ MORE

The efficacy score is driven mainly by a well-built hydrating base—glycerin, betaine, butylene glycol, emollients, and shea butter—plus a supportive barrier-friendly lipid system; the peptides are present at the end of the list, so they are likely low-dose support ingredients rather than the main functional engine. There is no evidence here of a strong treatment-level anti-aging active, and the formula looks better for hydration and comfort than for meaningful wrinkle correction.

EXTERNAL CITATIONS

Glycerin: Well-established humectant that increases stratum corneum water content.

Betaine: Humectant/osmolyte with evidence for improved hydration and reduced irritation in topical formulas.

Hydrogenated Lecithin: Barrier-supportive lipid commonly used to improve emulsion structure and skin feel.

Acetyl Hexapeptide-37: Peptide marketed for moisture-barrier support; topical evidence is much weaker than classic treatment actives.

Pentapeptide-48: Peptide marketed for anti-aging support; likely a secondary contributor in this formula.
