Tummy lines

Those are fold lines not wrinkles so the only way to reduce it is to fix your posture!

I second Amira's comment. I too have very deep lines on my tummy bcuz of long term bad postures it will cause fold lines so if you only recently change your posture of course it won't help and I doubt our fold lines will be gone 😂

are you referring to stretch marks? in that case, it’s no way to remove them using skincare. you have to go to a professional. skincare can reduce the appearance a tiny tiny bit, but it won’t remove them completely
