The newest addition to Chanel's Hydra Beauty range is a gentle-yet-powerful chemical exfoliator. The Chanel Hydra Beauty Camellia Glow Concentrate (£67) helps both hydrate and brighten the skin with a blend of three alpha hydroxy acids — citric, tartaric, and lactic acids (for a refresher on what all of those are, click here) — as well as two active ingredients extracted from camellia flowers (the signature flower of Chanel's fashion house and the key ingredient in the Hydra Beauty line). There's camellia yeast extract, from the camellia japonica, and camellia alba, from the white camellia, both of which help keep the skin hydrated and happy.
