This is probably the best Vitamin C serum I have ever used. I have been using for about 3 years. I have very thin skin so it is easily damaged. I put this on at night and wake up to a more healed skin.

This serum was on the expensive side and really didn't do anything. I saw very minor de puffing, absolutely no lifting of the eyelids. This did make my eyes burn, water and also made my lids sensitive. Returned for refund

those with sulfa/sulfate allergies cannot take or use glutathione, so out of caution it should be removed from the sulfate free catergory

[This review was collected as part of a promotion.] I love this product.. I always feel like I see results especially when I use it first thing in the morning.

[This review was collected as part of a promotion.] You can see your under eye wrinkles tighten as soon as you put this on! Big difference! I use this, morning and evening, on my lower and upper eyelids, after cleansing with Perricone Citrus Wash, then let the serum dry, and follow with the eye firming cream.

Either way I am very happy.. I am not easily "sold" on products but I got a sample of this with another product order and, since I have droopy eyelids I gave it a shot. To me it makes a huge difference! I notice it most when I see photographs of myself. My eyes seem to be wider open. It is actually amazing.

This is the first time I am writing a review, as I understand how important it is to many people who read reviews before such expensive purchase hoping for results. I have purchased this and the eye cream together as they were on offer as a bundle, and used them religiously for the last six months and have not seen any results. I am of Asian woman above 40 and have medium skin tone with dark circles and puffy eyes and no crows feet or majorly drooping eyelids. No brightness to my eye area, just felt nice, no reaction and lovely packaging. Not for me I guess!
