I'm kind of over weight and have developed stretch marks on the sides of my chest. Luckily they are still small and light. I plan on losing a lot of weight before I start hrt next year, and I just wanted to know if there was anything I can do now to prevent stretch marks before My breasts start to grow. Should i maybe apply colagen cream daily? Or Shea butter? I just don't want stretch marks covering all of my breasts, I want normal breasts.
