Carnosine
Carnosine is a naturally occurring dipeptide that is widely used in modern skincare formulas for its ability to help protect skin from environmental damage and support a firmer, more youthful-looking complexion.
How it works in skincare
In cosmetics and skincare, carnosine functions as a multi-tasking active that helps inhibit glycation – the process where sugar molecules bind to collagen and elastin, causing stiffness and loss of firmness. It also acts as an antioxidant, helping to neutralise free radicals generated by UV exposure and pollution while supporting the skin’s natural repair mechanisms, making it a popular choice in anti-ageing serums, eye creams and firming moisturisers.

Where it comes from
Carnosine is a dipeptide naturally present in animal muscle tissue. For cosmetic use it is produced synthetically to ensure purity and stability while remaining identical to the molecule found in nature.
