Acne Wash Causing Excessively Dry Skin?

It sounds like your skin is too sensitive for the harsh chemicals you're using. Go to a chemist & find a more natural cleanser. Sorry, all the brands I use are Australian! Basically, you want to avoid stuff like benzoyl peroxide, salicylic acid & azelaic acid. Look for stuff like tea tree oil and witch hazel instead. Use this once a day to start & use an oil free moisturizer twice a day. For particularly nasty spots you can either use a tea tree oil stick or a dob of toothpaste.
