I travel a lot and as Collagem is in the powder for I can take it everywhere with me. Been taking it for over 3 months now and really see the effects. My skin and hair improved tremendously. I spend a lot of time in the planes and it is not that great for my skin and hair but with taking COLLAGEM I can really see the improvement. I also used to get weak immune system and easily get a cold now I feel my immune system got much stronger as I am not getting colds as often.
