Supplement for skin...

I wonder how those celebrity and beautiful ladies out there keep their skin look very fresh and healthy though they expose their shiny, fresh looking skin (jeles nih) and there is no sight of scars or something similar to that (some of them expose the skin tooo much)... where they hide the scars?
x prenah kene gigit nyamuk ker?
x pernah jatuh ker?
Iv etried most of the stuff needed for the scar for moisture and i have this thought of not having enough supplement for myself in term of consuming something.

I have thought to take like immedeen, nuvafemme or anything similar...
have you girls out there who read this have an idea what best?

totally need your help...
