PHACE BIOACTIVE Illuminating Facial Serum with Hyaluronic Acid, 15% Vitamin C & E Dark Spot Corrector, Age Spots, Acne, Sun Damage, Collagen Boosting, Dermatologist Recommended, Oil Free, 1.0 Fl Oz

The packaging is substantial and protective of the active ingredients; however the formula seems quite tacky and has somewhat of a "medication" smell. Too soon to tell if there is any improvement.

I like the product and I purchased it for pigmentation problems. However, there is just one once which is way too little for a proper result and it would get quite expensive to keep ordering it. Other wise,if you want to keep it in your products. I think it will eventually work.

This is the most incredible and effective skin brightening serum I've ever tried (and I've tried many!). I've never been able to use a topical vitamin C product because it makes my skin red, itchy and irritated, but the formulation of Phace Bioactive Illuminating Serum is excellent--combining vitamin C, EGCG (the antioxidant found in green tea), licorice root (to help fade pigmentation) and hydrating hyaluronic acid. The whole foundation of Phace Biocative is key: protecting the skin's natural pH balance, which is why is doesn't make my skin red and angry. Never discontinue this!!!!

Vitamin C is 20x easier to for the skin to absorb topically! Vitamin C is the foundation of healthy skin. This is by far the best Vitamin C serum on the market. If I use nothing else, I use this.
