TGF β-1
TGF β-1 is a lab-made peptide used in high-end anti-ageing skincare to help support the skin’s natural renewal processes. It is valued for its ability to encourage collagen and elastin production, giving a firmer, smoother appearance over time. Shoppers will usually find it in premium serums and creams aimed at mature or photo-aged skin.
How it works in skincare
In cosmetics TGF β-1 works by signalling to skin cells to increase production of extracellular matrix components such as collagen, elastin and hyaluronic acid. When applied topically in carefully stabilised formulations it helps reinforce the dermal structure, improving firmness and reducing the look of fine lines and wrinkles. UK formulators use it at low concentrations within sophisticated delivery systems so the peptide can reach the deeper layers where it supports the skin’s own renewal mechanisms without irritation.

Where it comes from
Although naturally occurring in the human body, the TGF β-1 used in cosmetics is produced in laboratories via recombinant biotechnology. It is not sourced from plants, animals or minerals but is a bio-engineered copy of the human signalling protein.
Products with TGF β-1
