Skin acne and blemishes

I'm 19 and have suffered with bad acne all over my body since I was probably about 9 or 10. Since I was around 15 I noticed that the acne had spread to my butt and legs, espically the back of my thighs, I had always gone to the doctors and been prescribed things that never really helped all that much then the other week I accidentally picked up baby shampoo and started washing my body with it instead of normal soap (got the bottles confused and was half asleep) in the past few weeks my acne has cleared up massively on my butt and legs so I just thought I would put it on here as it could be useful for other people to know. Don't use baby shampoo on your skin everyday, I'd say I've found every 3 days is best and apply to particular areas you find you suffer with acne only. Baby shampoo also improved my dry scalp too!
