help! stretch marks /dryness

Hello I'm new here and new to skin brushing. I've been skin brushing my entire body 2x a day for the last week and I've payed extra attention to areas with stretchmarks. I've noticed that my skin where the stretch marks are has started to get patchy, dry, and starting to sting even though I apply lotions/oils 2x a day. I think I might be brushing too much and/or too hard on those areas. How many strokes or how much time should you brush a certain area withou going overboard? I'm taking a day or two for my skin to heal. Tweet
