So my 16 yo has spots like constantly.... she was put on acne treatment and pills last year and it cleared up.... but since Xmas it has got a whole lot worse again! So dr changed the cream and it’s makibg no difference! She drinks loads of water, is healthy, walks to and from school every day do gets plenty of fresh air and washes her face with plain water. Spot creams etc from the shops make it worse. Any suggestions?
