No, I’m not talking about callouses. I’ve only seen one client who had a callous on her chin. She was a multiple-daily tweezer and now that she has stopped tweezing at home, her chin is becoming soft.
I am talking about blaming PIH on increased blood flow. I don’t believe PIH has anything to do with callouses on the skin or inside a follicle. (Actually, I don’t believe that a callous could develop inside a follicle, either.)
My original post was to see how many colleagues believe that increased blood flow equals long lasting redness/PIH on the skin. I don’t. I may very well be alone on this belief. I believe that certain skins (and sometimes various levels of health) will result in long lasting redness and/or PIH from injury. Yes, I know that injured skin results in more blood to the area, but perhaps some chemical the blood brings, and/or reaction of melanocytes to the injury, and/or loss of opaqueness (related to melanocytes?), and/or the products applied after the injury are the CAUSE of the long term redness/PIH.
