Active ingredients
Biologically Optimised GuavaAnti-Ageing · Regenerating · Anti-Redness
A bioactive extract engineered to counteract cellular senescence—one of the primary drivers of skin ageing. By targeting and reducing the accumulation of senescent cells, it minimises chronic inflammation, a key factor in skin dullness and degradation. In addition, its anti-inflammatory properties help calm sensitised or stressed skin, reducing visible redness while strengthening the skin’s natural defence and resilience for healthier-looking skin over time.Collagen SegmentFirming & Lifting · Plumping
The Collagen Segment, composed of three amino acids, acts as building blocks for collagen protein. It stimulates skin cells to increase production of collagen, elastin, and hyaluronic acid, leading to increased skin plumpness and improved elasticity, which helps reduce wrinkles and tone the skin.Growth Factor TripeptideRegenerating · Skin Barrier Strengthening · Anti-Wrinkle
A synthetic tripeptide that mimics the body's Transforming Growth Factor Beta (TGF-β) pathway to stimulate collagen biosynthesis. By activating fibroblast activity, it not only enhances new collagen formation but also shields existing collagen from enzymatic degradation. It supports its ability to restore skin’s firmness and elasticity, yielding visibly smoother and more structured skin.Peony Root ExtractBrightening
A potent antioxidant-rich botanical known for its melanogenesis-inhibiting properties. Peony root extract interferes with melanin production pathways to combat hyperpigmentation, while its anti-inflammatory capabilities mitigate oxidative stress and irritation. It effectively restores skin’s radiance and promotes a more even complexion by reducing the appearance of dark spots and redness.GlycerinHydrating
Glycerin is a potent humectant commonly used in skincare for its powerful hydrating properties. It works by attracting water molecules from the atmosphere and retaining them in the deeper layers of the skin, effectively boosting hydration reservoir. This helps to plump up the skin, resulting in reduced dehydration lines and a soft, supple complexion.
