I've got acne on my back, and have had for some weeks now. I agree my back does feel like sandpaper, and it's a good job I can't see it. I haven't put anything on it, to try and make it go away, but I guess it must be hormonal, as I never used to get acne on my back before! Aaarghhh!!
Oh well, ...not much we can do about it I guess aye?! At least it's not on my face!
Maudie23: I've started using bio oil, but only on my tummy and thighs to try and prevent stetch marks, didn't want to put oil on my back incase it aggravated the acne, but if you think it works to improve it, I might try it. I thought it might be the soap I was using that was causing it, but I guess not! Doh!
