SkinCeuticals - QueenTania review for Phloretin CF

Vitamin c serum in a tinted dropper bottle to protect it from degradation due to light exposure. I’ve never used a vitamin c product before and I didn’t experience a bad reaction. I used it on a spot on my chest where i have pih. It has lightened but i think the quantity in this sample bottle won’t be enough to fade it completely. Im actually surprised that i saw a change so quickly. I think it faded on its own too and the serum helped partially.
