Stretch marks occur when the skin is suddenly stretched to the point that its internal structures suffer in terms of elasticity, such as when we gain weight or with pregnancies. In a breast augmentation, an implant is placed and the breast is inflated to a given volume, which may cause stretch marks. There are two concepts that you need to understand with stretch marks. If you have stretch marks before breast augmentation surgery, the stretch marks will still be there after surgery, but they actually are going to look better, because the skin will be stretched, making them less visible. If you do not have stretch marks and you get implants, you might develop them. When an implant is placed, the breast pocket needs to expand to accommodate its volume. The bigger the implant that you choose, the more likely it is that you will develop stretch marks. When an implant is placed, the skin stretches just like when we gain weight. So, yes, there is a risk of having stretch marks after breast augmentation surgery,although this depends on the patient’s skin elasticity and anatomy. The bigger the implant that you choose and the tighter your skin, the greater the chance of stretch marks.
