I had quite bad acne when I was 17 it went on for 3 years before I got some real help. I became increasingly more reclusive. I also suffered from associated depression. My parents became concerned that my acne would leave more than just superficial damage.
So my dad who is a (chemist) thankfully brought home some Celestone tablets one day. I had tried many acne treatments and they had all been relatively disappointing. After taking celestone for 2 weeks my acne had almost completely cleared and my skin healed. I did quite a bit of running and ate a lot of fruit as well which i think accelerated the healing.
Celestone made such a massive difference it basically changed my life. Obviously you have to use it with caution. But after taking it for around 6 months I stopped and my acne never came back. Hope this story helps someone out there. Google celestone tablets for more detail.
