Tetrapeptide-1
Tetrapeptide-1 is a peptide that supports a visibly firmer, more defined eye contour. It works by increasing expression of MBNL1 (Muscleblind-like protein 1), a protein that governs the transition of dermal skin cells (fibroblasts) into myofibroblasts — a stronger, contraction-capable form of cell that physically reorganises and tightens the collagen
network within the skin’s supportive extracellular matrix (ECM).
In vitro, this translates into measurable contraction of the dermal collagen matrix and a marked rise in EDA-fibronectin, a matrix protein associated with cell adhesion and myofibroblast activity. Both are consistent with a genuine tightening effect at the cellular level.
Tetrapeptide-1 has also been studied for its effect on mitochondrial function — the energy-producing process within virtually all cells. As mitochondrial output declines with age, muscle cells become less able to generate the energy needed to maintain healthy muscle tone, a factor that contributes to sagging in areas with fine, mobile musculature. By supporting both dermal matrix contraction and the muscle-cell energy that underpins tone, Tetrapeptide-1 addresses two separate contributors to periocular ageing — one structural (the skin’s collagen network) and one metabolic (the muscle beneath it) — in an area where thin skin and constant muscular movement make both effects especially visible.
Microalgal Biocomplex
Microalgal Biocomplex (Vegan Collagen Amino Acids + Spermidine) supports collagen production, hydration, barrier integrity and cell renewal. Three of the basic collagen-building amino acids, glycine, proline and hydroxyproline, supply dermal fibroblasts, the cells responsible for making collagen and elastin, with the raw materials they need to build these structural proteins. Spermidine works alongside these amino acids to support cell renewal, enhance fibroblast function, and support barrier resilience, with evidence also pointing to a role in calming low-grade inflammation linked to photoageing. Together, this multi-layered approach visibly reduces fine lines and smooths crepey texture, improving overall eye appearance.
Microalgal Biocomplex is derived from upcycled Haematococcus pluvialis microalgae. Its trio of amino acids, glycine, proline and hydroxyproline, is vegan in origin, offering a unique non-animal-based alternative to traditional collagen amino acids. In vitro, the complex also upregulates Aquaporin-3 and Aquaporin-5, water-channel proteins that transport water across the epidermis, supporting hydration both by binding water directly and by increasing the skin’s capacity to move it through.
Spermidine adds a distinct renewal mechanism, supporting the autophagy (programmed cell death) and cellular turnover pathways that decline with age, alongside dermal structure and barrier recovery through its effect on collagen synthesis and skin lipid production. Clinically, skin plumping, radiance and smoother, more even-looking texture appear within 10 minutes and continue to build, with firmness and wrinkle depth improving significantly against a placebo formula over 28 days. This ingredient is well-suited to the periocular area’s thinner, more fragile skin.
