Harper's Bazaar Best Serums & Treatments Award 2025.
Our Take
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. At $98 for 1 fl oz, it sits in the prestige indie serum zone—roughly what you'd pay for a comparable K-beauty or direct-to-consumer peptide play.
The Buying Guide
What to look at before you buy
01
Pea Peptides, Celtic Sea Plankton, Tiger Plant
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.
02
Lightweight serum, AM or PM application
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.
03
No silicones, colorants, sulfates, phthalates, parabens, PEGs, petrolatum, mineral oil; cruelty-free, non-GMO, EU/UK compliant
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.
