AHAs
AHAs, or alpha hydroxy acids, are a family of gentle exfoliating acids commonly used in UK skincare to help reveal smoother, brighter skin. Found in many cleansers, toners, serums and peels, they work by loosening the bonds between dead skin cells so they can be shed more easily. Popular types include glycolic acid, lactic acid and mandelic acid.
How it works in skincare
In cosmetics and skincare AHAs function as chemical exfoliants that weaken the intercellular glue holding together the outermost layer of dead skin cells, allowing them to slough away naturally. This process promotes a more even skin texture, improves the appearance of dullness and can enhance the absorption of other skincare ingredients. Formulated at the right pH and concentration, they are a staple in many British beauty routines for refining skin surface without physical scrubbing.
