Review (5/5): It works if you take it regularly.
It takes time but it works. Since it doesn't change your skin color over a night, it may be difficult to see the result. I've been taking it for one year. First six months I took it one capsule twice a day and I was satisfied with the result. At the end of six month, I reduced it to one capsule a day. Sometimes I check my old photos with the new ones and I can see the difference.
