What are they
Parabens are a group of synthetic compounds used as preservatives in cosmetics, skincare, and pharmaceuticals. Their primary role is to prevent the growth of bacteria, mould, and yeast in formulations, helping to keep products safe and stable over time.
How they work in skincare
Parabens are highly effective at very low concentrations, extending shelf life and maintaining product integrity. Despite ongoing debate, the ones used in cosmetics are strictly regulated and have been repeatedly assessed as safe for use at the permitted levels by global health authorities, including the UK’s Cosmetic Products Regulation and the EU’s Scientific Committee on Consumer Safety.
For individuals who prefer to avoid them, paraben-free formulations are now common and use alternative preservation systems. However, parabens remain one of the most efficient and well-studied preservative options in modern skincare.
