I like Vitamin C products in general, and if you get a good one they do work on brightening and lightening. They are great for summer and after sun exposure to help repair any damage and add antioxidants . Newest is Perricone MD Vitamin C Ester 15 and it is a good one.
You get 4 tubes of the product, which is great since Vitamin C is not stable when exposed to light and these individual tubes keep the light and air out ensuring long term stability.
I got one tube to test and while the company states that each tube would last a week, I'm well into week 2 with mine with a nice bit left. I don't use it on my T Zone so that may be part of it but it seems to me there is more than a week's worth in the tube and that's great.
In my test period I've been quite happy. There hasn't been a huge difference but a subtle one. And I know that brightening takes time, a good bit of time. But my skin has more clarity and glow and some spots have been beaten back a little. It's got a lot of firming action going on too. Firming you can see.
The formula is nice and creamy but not heavy, with light moisture. Just enough for my oily skin but if you are dry you might need to layer night cream over it. It sinks in fast and you do not need a lot.
According to Perricone MD, the chief ingredient, Vitamin C Ester , comes in at 15 % which is the "highest concentration in any anti- aging treatment ." They also tell us " Vitamin C Ester is a fusion of Vitamin C with a fatty acid derived from palm oil."
I'd be happy to use this all summer with it's just right feel and high Vitamin C percentage.
Perricone MD Vitamin C Ester 15 is $ 120.00 for 4 10 ml tubes and available at www.sephora.com and Sephora stores.
