iS Clinical Youth Serum
Why We Love This Product
A lightweight peptide serum. iS Clinical lists copper Tripeptide-1 and Tripeptide-10 Citrulline alongside centella asiatica, caffeine and their Extremozyme complex. No percentages are published, though caffeine sits third on the ingredient list, which is high. The texture is a thin gel that dries down quickly and leaves a slight film, and it layers cleanly under cream and under makeup.
It suits most skin types, including oily, and it can be taken right up to the eye area. Use one or two drops in the morning on clean skin, before moisturizer and SPF. Warm it in the palm first. Because of the film it leaves, always apply it before anything heavier, never after.
