It takes a while to show some ‘effects’,but then again it’s just a serum not a miracle.I guess it depends on the skin issues (mine are ageing,hyperpigmentation,wrinkles,big pores etc).It didn’t help at all with my hyperpigmentation,but the skin does look brighter and clearer. The scent is ok,if you like oranges.I only used one bottle,so that’s not much. With my skin concerns,I should have combined it with Retinol.
