The only solution for stubborn stretch marks is laser...
No they don't go away but may fade a bit over time and depending on how deep they are.
I have tried everything but it doesnt seem to be working.
I have been looking into the best stretch mark oil and found a brand called earth mama. I ordered it on Amazon and waiting for it in the mail. The reviews are really impressive.
I've struggled with stretchmarks all my life. I started using Burts bees belly butter and mixing ot with bio oil. Stretchmarks that have been there before are fading and I'm yet to get any.
