HEXAPEPTIDE FIRMING SERUM

Supports firmer, more elastic skin

Firms and improves elasticity with signal peptides.

The texture

A hexapeptide firming serum for the look of firmer, more elastic skin. Hexapeptide-11 works through the signaling-peptide mechanism class, while a natural ceramide complex and multi-weight hyaluronic acid comfort and plump the barrier for a hydrated, more comfortable finish.

The study behind it

Hexapeptide-11 is a synthetic signal peptide studied in human dermal fibroblasts, where published research reported support for the skin's proteostasis processes and an improvement in skin elasticity in an in vivo deformation assay.1

  1. 1 Sklirou AD, et al. Redox Biology, 2015 (PMID 25974626).

How to use it

  1. Apply two to three drops to clean skin morning and evening, after toner and before moisturiser.

Built around named actives

19 formulas and 12 sets, gathered around actives that include peptides, bioretinol and vitamin C derivatives. Every formula names the study behind its key active.

What each formula is built to do

Supports firmer, more elastic skin

HEXAPEPTIDE FIRMING SERUM

Hexapeptide-11 is a synthetic signal peptide studied in human dermal fibroblasts, where published research reported support for the skin's proteostasis processes and an improvement in skin elasticity in an in vivo deformation assay.1

Visibly smooths and evens, without retinol

CELLULAR ANTI-AGING BAKUCHIOL RENEWAL OIL

Bakuchiol is a plant-derived compound studied in cosmetics as a gentler alternative to retinol, with a randomized controlled trial reporting improvement in the appearance of photoaged skin comparable to retinol and better tolerated.2

Stable vitamin c for antioxidant defence

CELLULAR ANTI-AGING ASCORBYL GLUCOSIDE SERUM

Ascorbyl Glucoside is a stable vitamin C derivative that skin converts to active vitamin C. In lab-grown skin, a formula with 1.8% ascorbyl glucoside was as effective an antioxidant as one with 15% vitamin C, and unlike vitamin C it stayed stable in storage.3

Smoother, more refined skin texture

CELLULAR ANTI-AGING RESURFACING CONCENTRATE

Lactic Acid is an alpha-hydroxy acid studied in cosmetics for gently exfoliating the skin's surface, supporting a smoother, more even-looking texture.4

The actives behind the collection

The five found most often across these formulas.

Marine bioferment

A ferment made by Alteromonas bacteria, listed in the EU cosmetic ingredient database as a skin-conditioning ingredient.

European Commission CosIng database, Alteromonas Ferment Extract, entry 54308.

Bidens pilosa

A plant-based retinol alternative. Tested on its own in the lab, it gave a small rise in the activity of RXR alpha, a receptor retinol also works through, without activating the receptor linked to retinol irritation.

Ye S, et al. Biomolecules, 2025 (PMID 40001599).

Multi-weight hyaluronic acid

Known for its strong water-binding potential. In a 60-day study, hyaluronic acid creams improved skin elasticity compared with a placebo cream.

Pavicic T, et al. Journal of Drugs in Dermatology, 2011 (PMID 22052267).

Collagen amino ester

A collagen-derived amino-acid ester that helps condition the skin.

European Commission CosIng database, Dipalmitoyl Hydroxyproline, entry 75923.
