Boots boasts a brilliant selection of French pharmacy skincare including Vichy and Avène Eau Thermale. But for anyone with blemish-prone skin, La Roche-Posay Effaclar Duo + (£17) is well worth snapping up and slathering on. It contains a cocktail of spot-fighting, sebum reducing, and skin calming ingredients like salicylic acid, zinc, and niacinamide.
