Women/teen girls only?

I get the bumps too, usually it is ingrown hairs starting. I found mine disappeared if i exfoliated before shaving, just get a loofa for about $2 from most shops and rub your legs with it before shaving. Moisturizing afterwards helps too. As for the best razor the keep your skin hydrated, try one of the ones with the built in soap/lather they contain moisturizer most of the time.
