Liquid Peptides

Ten peptides, three strategies

Signal peptides, the Matrixyl-family palmitoyl tripeptides 1, 5 and 38 with tetrapeptides 7 and 21, read to skin as fragments of broken collagen, nudging fibroblasts toward renewal. Expression peptides, acetyl hexapeptide-8 (Argireline) with its classic partner pentapeptide-18, gently soften the intensity of micro-contractions. And carrier peptides, led by a copper heptapeptide, ferry the mineral collagen cross-linking depends on. Carnosine, an antioxidant dipeptide, guards the lot.

The delivery idea

Peptides are water-loving and skin is not; here a cyclodextrin shuttle and a drone-style targeting approach concentrate the payload where it is useful rather than leaving it on the surface.

The base does quiet work

Hyaluronic acid, panthenol and glycerin hydrate, while inulin and alpha-glucan oligosaccharide, two prebiotics, feed the skin’s beneficial surface flora. Fragrance-free; the lactic/glycolic entry near the end is a film-forming copolymer, not an exfoliating acid.

The honest frame

Peptides are diplomats, not surgeons: published effects are gradual softening and firming over weeks, at zero irritation cost, which is exactly their appeal.

Visible ageing in skin that cannot or will not run retinoids, including during pregnancy and breastfeeding, where peptides are the ageing-support option of choice, and committed routines wanting a day-shift firming layer alongside a night retinoid.

Worth knowing

Fragrance-free, acid-free, and about as low-conflict as serums get. Results are judged in eight-to-twelve-week horizons; peptides reward the patient.

Morning and/or evening on clean skin: 3–4 drops pressed over face and neck before moisturiser.

Plays without conflict alongside every active on the shelf.

Use alongside

The daytime firming partner to a Crystal Retinal night, or the complete ageing serum for retinoid-free routines. Under any moisturiser, over Hydr8 B5 if layering serums (thinnest first). It holds the dedicated-peptide chair alongside Affirm and the Youth line’s peptide creams: one peptide leader per routine is plenty.
