Rated 5 out of 5 by from It Works! I highly recommend this product. I haven’t been using this but a couple of weeks...and not even every day and it has lightened sun spots on my face considerably. I can really see the difference. I will be buying more of this in the future to help lighten my sunspotson my chest. Great purchase.

Rated 5 out of 5 by from Another Winner From PTR I've been using PTR's retinol serum at night for a number of years. I decided to try his Vitamin C line, and I'm equally as impressed, this product in particular. In a very short period of time, it starts to work to get rid of brown/dark spots, and I can see a visible change. I have tried other things including prescription products from my dermatologist, but nothing works as well as this on sun/brown/dark spots. I wish I had taken a before/after photo!

Rated 5 out of 5 by from Noticed a difference in 1 week! Yes I would highly recommend this product! I purchased about a week ago and have significantly noticed the dark spots on my hands fading away. I’m extremly happy with this product and would highly recommend it to anyone who wants to lighten their age spots away.
