Just something that i tried and has actually worked!!!
i have acne prone, combination skin. and no matter what ive tried always have break outs. I saw this video www.dhukai.com/at-home-acne-spot-treatment-with-activated-charcoal/ and i was very skeptical but tried it as it was alot cheaper! I went to Holland and Barratt and got both items for around £10
Just thought i would recommend! hope it works :)
