The Beauty4Lyfe Retinol Vitamin C Serum has not worked for me yet. Any fine lines and wrinkles showed no improvement and any dark circles that I have also did not fade. I would have to use this Retinol Vitamin C Serum for a longer time to see any results but the seller wanted the review so I am writing it based on the length of time that I have used the product. The potential is there for this product to be effective. It supposedly reduces wrinkles, fades dark circles, hydrates to firm and lift skin. It is made from natural ingredients to nourish the skin. #RankBoosterReview ii, #Sponsored iii, Beauty4Lyfe Retinol Vitamin C Serum, https://www.amazon.com/gp/product/B077MRCRY5/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
