I already finish a whole bottle of this serum and doesn't work on my face. I'm a fan of Night Advanced Repair, which makes my skin feel great and lump after every night. Then I decided to try this one once time instead because I wanted to reduce dark spots on my skin. But it did not work, so I just switched back to Advanced Repair last night and this morning my skin feels like it is re-alive again. It doesn't feel this healthy and shiny for a while when I'm on the Perfectionist Serum, I feel like Perfectionist Serum does not hydrate a lot as well, my skin is kind of drier when I'm on Perfectionist. And it is not worth the price too. I will go back to Advanced Repair and will find a different product for dark spots. Originally posted on www.esteelauder.co.uk
