Thank-you so much for your enquiry. The truth is, without seeing you and doing a bit more research into your medical history and any changes you are currently experience, product usage etc, it’s very difficult to give you a definite cause for the bumps on your forehead. It could be any of the following things: 1) Hormonal changes; 2) New medication; 3) Changes in your skin care products; 4) An allergy that you may have developed; 5) Illness or having recently been on medication; 6) Stress; 7) Have you lately started wearing caps or scarves around your head? 8) With the weather changing, are you perhaps sweating more on the forehead? 9) Have you perhaps started a new job that requires you to be outside more? Or that you’re on the road more than you were previously? So you see, there is so much that we need to investigate, before we can just pin point a cause. My suggestion is that you perhaps come to one of our Skin Renewal Branches and have a consult with a Dr so that we can give you the best possible advice.
