First off WELCOME!
Secondly, I have some of these issues as well. I mean I have grey skin south of the border and a few issues there with raw skin and such. I can't seem to find anything to work lol, but that is mostly because of my limitations due to my allergies and such.
A few things I've noticed though and this probably is going to get a "me too" from everyone:
- The more weight I loose the better my skin gets
- The grey or dirty looking skin is getting better. I notice this every time I loose about 10 pounds. I look and things are just "better"
- Rashes are getting less and less. Now I'm dealing with scalp issues mostly, which are stable, but annoying. I believe it is a yeast thing anyhow. Even my down south issues are the same, candida related, which is common for us big gals. A few things I've been doing to help along that is cutting out vinegar as much as possible. Along with that, sugar and that includes corn, even raw. Starchy things as well. All of these can feed and produce candida overgrowth so I think dietary changes are key in the healing process.
- Powder can make things worse. If something is moist then I have found powder either feeds the area, rubs it more raw, or creates an icky paste. I only use powder when I have light issues. Like my bra rubbing on my skin, under my breasts, and making it a bit irritated. I use the new Gold Bond Healing powders and that works great and smells good. It is talc free, but I believe it is cornstarch based, which isn't ideal, but it works for the small stuff for me personally. I only use it under my boobs though, which have their own issues haha.
- The more I read and research, the more I am hearing that the cure all is Zinc lol. Even with scalp conditions. Zinc zinc zinc. That brings me to "Head and Shoulders" or shampoos that have Zinc based. I started using that as a body was, in a non-sensitive area that is south of the border, and the results are slow, but I'm starting to believe that it is doing something. Using it all over my body would be a no-no for me, but in select areas it is okay. I suggest trying it.
- Tea tree oil is good. I've been using that for a long time. It can cause an allergic reaction so make sure you test it on yourself first. However, it is a natural antiseptic, powerful, smells to high heaven, but the oil absorbs into the skin much differently than a cream. It also helps with itching. I put it on my scalp and it burns lightly for a bit, then the itching will stop for hours and hours.
I love the stuff. I use it for cuts, some rashes, and more.
