After just a few use of the hyperpigmentation patches I saw a huge difference on my problem area. I was suffering from severe hyperpigmentation around my chin after my pregnancy. I've been to derms, had laser treatments, used a ton of products and after 2.5 years of trying my hyperpigmentation reduced slightly. When I started using Luna patches I didn't have high hopes but after using it a few times, I saw a noticeable reduction. I'm very impressed and I think that if used consistently these patches can do miracles!
