You'll really need to be more specific about what is happening with your skin: you said you "had" acne – how long ago did it start to clear? What treatment were you using? Since you said your face is now soft, do you mean the treatment was causing it to be very dry and rough? If it's only been a few months since the acne cleared, you are probably talking about post-inflammatory hyperpigmentation. These occur in areas where a pimple has healed. If you were on isotretinoin and are now getting NEW acne cysts, you may need a second round of treatment. If they are small pimples, another medication applied topically will help.

Vitamin E may help with scarring, but you should also apply the gel right on the areas that are healing. You can also ask your dermatologist about taking a LITTLE extra Vitamin A for a while if your skin has become oily. Don't take extra Vit A without consulting your doctor first – it's a fat soluble vitamin so your body retains it (it doesn't quickly excrete through the kidneys like some other vitamins) and it can build up over time and cause serious problems.

well you could go to doctor or just leave it alone. i got the same problem. i leave it alone and its gone! i dont know why…..

It will clear up in time.
