Yes, the products of American Meilei are really effective. I used to have dysmenorrhea, dark yellow skin, and many spots and fine lines on my face. Really ugly. Thanks to Meilei in America, I can't believe it. I only took it for three months, and the problem of dysmenorrhea is getting better and better. Wrinkles disappeared, spots faded, and skin became healthy. Now my body is completely healthy.
