Has anyone used this face wash before? I was having break outs on my chin area which was unusual for me so I thought I'd try this and it has reeeeeally helped with spots I think it's really good. I've been using it for a couple months now and spots cleared but just keep finding that every day I have black heads surfacing. I can feel bumps on my skin and its blackheads. Gross but am I using the face wash too often? I only use once a day. Google says something about purging but I thought that would have just been for the first few weeks. I have exfoliated my face once a week recently too which hasn't helped either but thought I'd try that
