EGCG
EGCG (epigallocatechin gallate) is the primary catechin in green tea — accounting for 50–60% of total catechin content in high-quality shade-grown leaves — and the most biologically active polyphenol identified in modern longevity research. It is the only molecule with direct, peer-reviewed evidence acting simultaneously on multiple primary drivers of cellular aging.
The ultimate longevity antioxidant
Beyond free radical scavenging, EGCG operates at the level of cellular integrity: it protects DNA from damage, inhibits the molecular pathways that accelerate cellular senescence, and limits the accumulation of inflammatory signals that degrade surrounding tissue over time. In short, while traditional antioxidants intercept damage after the fact, EGCG works upstream — preserving the cell's own capacity to replicate, repair and renew itself.
Unlike conventional green tea extracts used in cosmetics — which deliver a broad, diluted and rapidly degrading mixture of polyphenols — ALPHASCIENCE isolated and stabilized EGCG at 4% concentration: a cosmetic first, protected by patent pending BE2024/5950.
Ensuring the formulation of this potent catechin fraction in a cosmetic formula while ensuring its stability and bioactivity at therapeutic concentration throughout the product lifespan is a true breakthrough in longevity skincare.
Skin benefits
EGCG is one of the most extensively researched longevity molecules in existence — a single antioxidant compound capable of intervening at every stage of skin aging, from the first oxidative trigger to the visible loss of structure and radiance.
- Protect skin cells from oxidative damage that drives premature aging at its source
- Slows the enzymatic breakdown of collagen and elastin, maintaining firmness and elasticity over time
- Minimizes inflammaging by inhibiting the chronic inflammatory cascade that accelerate skin aging
- Reduces the dullness, discoloration, and uneven texture associated with photoaging and oxidative stress
