The most incredible supplements I have ever tried for acne are L-Glutathione (500 milligrams up to 3 times a day) and vitamin B6 (ONLY get the P5P form. The other form can cause neuropathy). Split a 50 milligram pill of vitamin B6 (P5P) up and take a few times a day. I would ask your doctor about going up to as high as 100 milligrams of P5P if you really need that much to keep your skin clear. My skin is completely clear as long as I take the B6 or the L-Glutathione. I do not need to take both of these supplements together to have clear skin, - both have worked separately equally as well to clear my skin in record time (about a week to see results) but test it out and see what works for you - both have amazing health benefits. I have noticed that L-Glutathione has the added benefit of also making my hair really shiny and healthy looking.
Both vitamin B6 and L-Glutathione are potent detoxifiers of the liver so go up to the dose you need VERY slowly! If you break out initially, bear with it - this is just a detox/cleansing reaction.
Try opening a capsule of vitamin B6 (P5P) and take a third of it - or half of it - and see how you do Same goes with the L-Glutathione pills or powder . You can take the same dosage up to 3 times a day. Definitely take the B6 with food because it can make you nauseous. Also, the B6 (P5P) could keep you up by giving you energy if you take it late at night.
Topically, Jojoba oil is great for acne. It moisturizes without clogging pores. I wear it all over my face and neck at night. It is the only moisturizer that does not break me out!
I have suffered with severe cystic acne and was on 3 courses of Accutane so I know what it's like to suffer with acne. With either of these supplements, thankfully I don't have to suffer anymore. I hope this info helps anyone out there who is struggling with acne.
