)) 2× 10 ML Bottles of Biossance Squalane with 10 % Vitamin C & White Shitake to visibly improve discoloration and even skintone. )) This is, by far, the BEST Discoloration Serum I have ever tried. I had a lot of discoloration all across my forehead for several years, and after finishing off 2 of these bottles, it is completely gone. )) Can double as a daily brightening serum to help prevent dark spots and keep your natural glow.
