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.
