Sea buckthorn extract and niacinamide — a fast-absorbing ampoule that improves skin tone.

The Isntree C-Niacin Toning Ampoule combines Hippophae Rhamnoides (sea buckthorn) fruit extract with niacinamide and 3-O-Ethyl Ascorbic Acid to help improve the look of uneven tone and dullness while nourishing the skin. Its lightweight, fast-absorbing texture layers easily under cream or sunscreen, with hydrating components included so the formula feels glowy rather than dry. Pair with SPF in daytime routines.
