Sure, the Skingredients Skin Veg (£39) pre-serum is best known as a hyaluronic acid-based hydrating serum. But the supremely gentle, fragrance-free formula also contains a nice amount of polyhydroxy acid to simultaneously help with exfoliation. The result? Your skin looks plumper, smoother, and brighter with continued use. Apply it after you've washed your face and before your face cream. If your skin is on the oilier side, then this serum may be all you need (well, and SPF during the day, of course).
