Skin brushing feels great, when someone else is doing it. I used to get it at as a spa treatment. I have been looking for a good cactus brush, but can't find one for less than $35. I think you have a great odds on your side with the youth/length of time. I am not s lucky, but am still hopeful.
I am also adding the Dove replenishing/rejuvenating body wash to my routine. I scrub with the loofah, just like the dry brushing routine. Can't hurt.
