Do you mean stretch marks? They’ll fade but never go away completely.

I doubt they will ever fade completely but some oils and creams can help

I don’t have visible scars from giving birth. I do have 3 small scars from having my appendix out and you can’t really see them now, 8 years later. Mind you, one is hidden in my pubes and one is in my belly button, obvious why I can’t see them I suppose

You need to start applying cream… for stretch marks, anti-wrinkle, general vitamin E, anti-ageing creams, coconut oils etc. anything that will help the skin turn over new cells quickly. Also consider diet and make sure you are eating collagen promoting foods, along with actually digesting plenty of vitamin E and C from fresh fruits and vegetables to help your skin along. Marks are so much easier to deal with then hanging dead skin (see this mother’s post-baby belly experience as she comes clean about it!

but good skin care, and time and patience really does help even the sagging skin that can remain after a pregnancy.

They will definitely fade, but i expect that they will always be there.
