Before using Vitamin C serum I felt the skin dried even after moisturizer. It had an uneven colour. First impression was it was hard to control the flow, was not expecting the contents to be quite so liquid. How if felt on the skin was tingly yet not drying. But I liked how the skin reacted, almost like the hair products, tingly, and fresh. After using Vitamin C Serum, when I look at the photos my skin has a vibrancy, more even and looks less dry and wrinkles are calmer.

Skin concerns before trying product was to combat signs of aging like crepey skin ( especially neck) and age spots. AM 5-6 drops of Vit C serum over face and neck followed by All in One product.혻 Let products soak in and then sunscreen ( if going outside in the next few hours). PM same routine with Vit C and All in One plus light eye cream. First impression was the Vit C not discolored like some other previous products, seemed ?쐄resher,??felt good on face, not greasy. I feel my skin looks healthier by looking brighter and well hydrated. I really Dr Louie products and plan to keep using and also explore more of the products offered in this same line.혻 I feel the products are higher quality and I like that they have been screened for safety.

Amazing

In just 2 weeks, my skin is brighter and the hyperpigmentation on my left cheek is greatly reduced. I awaken and my skin feels/looks moist/hydrated. And, I only need one product/serum now because this Vitamin C Serum is full of ingredients that are good for the skin and don't clog the pores. I'm very pleased with this product.
