Well in theroy, water works best. Why? Cuz you you wonder why breakouts comes about, thats becuz you removed the layer of oil that is present on your skin. Obviously, thats when your skin starts to reproduce more. Too much excessive oil, blotted, thus pimples. Same problem for ppl who dun wash up their make-up at the end of everyday.
But if you stilll want to consider facial wash, get something that is neutral in pH value. In addition, use only a pinkie fingertip of foam. DO NOT OVERUSE! Too much foam, too much alkaline, too dry for skin! Next start rubbing your palms of the fingertip of foam until there is enough for your face. DO NOT APPLY PRESSURE ON YOUR FACE, treat it gently. Wash up, and apply moisturiser if you need. Toner if you need but pick brands that dun contain alchol (drys up skin) - eg. CLINIQUE.
For emergency outbreaks, use CLINIQUE's anti-blemish solutions night treatment gel. Does the job well by getting rid of pimples within 2 days. For acne bumps, it will take a 1week. Been using this product since secondary school and now I am 22.
