Isntree Serums & Ampoules

Isntree prints its strengths plainly, so read the number: Hyper Niacinamide 20 and Hyper Vitamin C 23 are high dose products and Hyper Retinol EX 1.0 is an evening one, none of which belong in the same routine on the same night. The Onion Newpair and Mugwort ampoules carry no acid or retinoid, and the Ultra-Low Molecular Hyaluronic Acid serum is pure hydration.
