I have really dry skin, but have acne in my t-zone, chin and middle of my forehead. Have started using Dermalogia acne treatment but they don't recommend a moisturiser-what should I use? Have tried Liz Earle and L'Occitane, and loved L'Occitane, but apparently moisturisers could be the cause of my acne. I want to stick to Dermalogia if I can-any advice? Thank you ladies!
