You can’t really tighten your vagina. What you can do is tighten your pelvic floor muscles, which surround the vagina. We offer a variety of products designed to help you improve pelvic floor tone, as well as instructions on how to do Kegel exercises.
There are some laser treatments that have been offered to tighten the vagina. They’re relatively new treatment options, and the outcomes seem quite variable.
I hope this helps! (And I’ll note that strengthening your pelvic floor is also good for preventing incontinence, so there’s lots of reason to develop the Kegel habit!)
