Tranexamic acid

Tranexamic acid is a skincare ingredient that helps fade dark spots, even out skin tone and brighten dull complexions. It has become a favourite in UK serums and creams for tackling pigmentation without the irritation often associated with stronger actives. Gentle enough for most skin types, it delivers visible clarity and radiance with regular use.

How it works in skincare

In cosmetics tranexamic acid works by interrupting the pathways that trigger excess melanin production, particularly those triggered by UV exposure, inflammation or hormonal factors. It is valued for its ability to visibly reduce the appearance of post-inflammatory hyperpigmentation, sun spots and melasma-like discolouration while supporting a more uniform, luminous skin tone. Formulators often pair it with niacinamide, vitamin C or hyaluronic acid in lightweight serums and brightening moisturisers.
