[YEA] I'd been having troubles with my skin lately and for another reason (broken capillaries) I had been taking very large doses of Vitamin C internally (with Lysine)... it's still to early to tell if it's working. But I noticed a MARKED IMPROVEMENT in the condition of my skin in regards to breakouts... they were diminishing dramatically. So I decided to apply it topically. You can Ascorbic Acid powder in a variety of health food store, and if you go to your local large beauty store there is a famous brand that sells a topical vitamin C powder (it's very expensive - sourcing out ascorbic acid powder is definitely cheaper). Mix a tiny tiny scoop (maybe 1/16th of a teaspoon) into your moisturizer every morning and apply it. You may feel a tiny sting from the vitamin C but it shouldn't be uncomfortable and it should disappear almost instantly. If the sting lasts, you've used too much powder! You'll notice an immediate improvement in your skin and I bet you'll be acne free within a week... Do this only in the morning - no need to overload your skin at night. Plus Vitamin C is a very powerful anti-free-radical and anti-aging product.
