I use Sproulet freckle removing products for internal and external use of plants. Because some products have been used before, the skin is very thin and the allergic spots have not been removed, so I dare not use them indiscriminately. When I saw this product on the Internet, I wanted to try it for external use, and the effect was quite good. I'm still using it. The spots have faded a lot. You can also learn about it.
