Stretchmarks 😧

So I have purple stretchmarks all over my breasts that have been there for just under a year. Does anyone know any easy to get creams or at home treatments to fade them. I realise that they won't ever go away fully but being the teenager I am, I just want to feel good in my own body and beable to wear a bikini without feeling selfconscious because of how many stretchmarks I have.
