IT'S SKIN

It's Skin is a Korean skincare brand developed alongside dermatologists, pairing clinical know-how with targeted, concern-specific formulas.

It's best known for the Power 10 Formula range — a line of colour-coded, highly concentrated "effector" serums that each target a different concern (the VC Vitamin C effector for radiance is a long-time favourite).
