Hi, you can get it by the right amount of sleep, good diet habits, regular excercise and fresh air.
Also, many vitamins contribute towards glowing skin. I find that primrose oil and flax seed oil really give my skin a lovely glow.
But if your skin is not glowing, its not one remedy that fits all. You have to find the underlying cause first, then address the cause. What is the reason, is it lack of sleep, illness, kidney problems, liver what?
