A clean, peptide-forward serum that delivers on everyday firming without the complexity.
Pea peptides are having a moment, and this serum bottles them with Celtic Sea Plankton and Tiger Plant for a botanical angle most peptide serums skip.
$98 for 1 fl oz is premium but aligned with award-winning indie serums and peptide-forward formulas at Sephora tier.
Who it is forBest for those who want peptide support without retinol or vitamin C intensity, or anyone committed to a clean ingredient list and willing to invest in efficacy over volume.
What to check before you buy
Core Actives
Peptides are small enough to signal the skin without the heaviness of protein. Pea peptides specifically have amino acid chains that work to plump appearance and support elasticity. The sea plankton and tiger plant add antioxidant and barrier-support texture without fragrance or synthetic glow—clean formulation all the way.
Texture & Ritual
This is a thin-bodied serum you layer under moisturizer, not a standalone treatment. The application ritual is minimal: clean skin, small amount, follow with hydrator. That restraint signals confidence in the formula rather than relying on layering tricks.
Clean Standards
The exclusion list is long and specific—this isn't a surface-level 'clean' claim. EU and UK standard compliance is the gold standard for ingredient scrutiny, so you're getting a product that had to clear higher regulatory bars than US-only brands face.
