The shiny skin is where your skin it stretched tight, once you start to drop and fluff the shinyness will go. Creams don’t actually stop stretch marks as they are deep in to the layers of your skin, whether you get them or not is more to do with your genetics than anything else. Creams only get through the top layer of the skin so sadly an’t prevent or repair stretch marks but they can lighten them and make them considerably less noticeable if you do get them( however what you’re nitcing here are not strech marks yay!) . I find Palmers Coco butter great, you can rub the cream in the top part of your breast just avoid the incision area. Hope this helps x
