Was a long time favorite of mine before update
This was my favorite Vitamin C and Hyaluronic Acid lotion. I used it for many years and could definitely notice an improvement of my forehead lines when used daily. It seems the formulation is now reformulated and the ratio of Vitamin-C has been obviously been reduced. As others have mentioned, it's more of a white color rather than the slight orange/yellow tint it was previously and it no longer makes the "tingling" sensation upon application. I have a couple bottles left but I am not a fan of the new formulation so I will have to look at other options.

Hi there. Thank you for sharing your experience with Powerful-Strength Vitamin C Serum. It is possible minor changes were made to the product formula; however, the performance should meet or exceed previous results and may not be noticeable. There are different reasons why a formula might be changed; availability of ingredients, changing industry requirements, and product improvements are common examples. The ingredients listed on the physical product are always accurate listing. We hope this helps!

Have acne scars? Give this a try!!!
This serum is potent and packed with vitamin c! Don’t worry about the slight tingly feeling because that is the Vitamin C serum working its magic. Easy to open packaging with a gentle scent that is not offensive. Perfect for evening out my skin from acne scars.
