Some of my stretch marks on my thighs and butt started fading, but the ones on the front of my quads/hips have been getting worse. I also recently started noticing darkening/yellowing, wrinkles, and cellulitis. The stretch mark around my armpit is getting better, but now there's a dark spot on my chest close to it. Many of my thigh stretch marks have discoloration in the surrounding skin too. None of the discoloration is purple like a bruise (except for the stretch marks). The discoloration is yellow like my skin has darkened, and it doesn't hurt. I can see lines that appear to align with the muscle fibers like the collagen in my skin has deterioriated. Is there anything I can do to improve these skin problems without spending a fortune? Why is some of it getting worse?
