I've used other products that cost much more in the past (OTC and prescription). I am African America and suffer from hyper pigmentation. A friend told me to try this product and I started to see results within 1 week. I've even tried it on my elbows and knees. It did not make my skin as sensitive to the sunlight, which is an added bonus. This product worked so well I had to tell my dermatologist.
Not impressed with this serum. It made my skin feel softer, but after continued use I didn't see any results. I have also been experiencing break-outs along the hairline with all the MD skincare products.
While this product made my skin feel better, it did not do anything for the age spots with respect to lightening them. Very expensive product, I expected more for my money):
