Tree of Life Vitamin C

Wonderful Serum, definitely can see a glow after about 2 weeks of usage. My skin is even toned now and radiant. 1 drop is all it takes, thick serum but applies nicely and smoothly over the face. If you put too much, your face will be sticky.
I apply Vitamin C morning and night
with Tree of Life Hyaluronic Acid (in the AM only)
with Tree of Life Retinol (in the PM only ) - note: Retinol can cause breakout (skin purging) for 2 weeks, but then it will be all worth it :)
