THE GLOSSARY OF GLOW
GLYCOLIC
An AHA derived from sugar cane, ‘glycolic is one of the smallest molecular structures in the family of AHAS, so it can penetrate the skin more deeply’, Dr Gross says. ‘It exfoliates dead skin cells and may stimulate collagen production for smoothing fine lines and wrinkles.’

HYALURONIC
This one isn’t like the others. ‘Hyaluronic acid is defined as an acid, but it’s not exfoliative in the exact same way others are,’ says Dr Henry. ‘It’s a humectant, so it draws in a lot of water.’ In fact, it’s known for holding nearly 1,000 times its weight in water and attracting and locking in moisture to the skin. It’s also a substance your body produces naturally, so it’s familiar.

SALICYLIC
Yes, it’s the go-to acid for oily, acne-prone skin and this BHA found in plants sloughs off dead skin cells while also quelling inflammation and going up against breakouts. ‘Those not prone to acne can use it; you just have to be careful – it can be aggressive,’ Dr Lain says.

LACTIC
A derm favourite for its gentleness, this AHA is derived from milk (there are plant-based alternatives). ‘Lactic acid not only exfoliates but speeds up cellular turnover and revives collagen production, which makes skin look firmer and smoother,’says Dr Gross.

FERULIC
Found in the cell walls of plants, ferulic neutralises free radicals formed by pollution and UV rays. ‘A naturally derived antioxidant, it helps to stabilise others, specifically vitamin C,’ says Dr Lain. ‘Vitamin C is probably the most powerful antioxidant, but it’s unstable [so it needs help].’
