You are probably talking about stretch marks. Thanks for the query. Stretch marks are amenable to different therapeutic modalities with different success rates. Fraxel lasers offers most desirable results and have a downtime of 1-2 weeks. Other modalities include dermaroller with mesotherapy or only dermaroller and platelet rich plasma therapy. Certain topical also assist these treatments. Meet a Dermatologist for better and realistic understanding of the various procedures. Hope it helps.
