SweatBlock® Antiperspirants for Excessive Sweating and Odor ad: Years of sweat stains, gone in one wipe

Things I stopped doing since my son started using SweatBlock: Pre-treating pit stains on every load. Buying him black shirts only. Pretending I didn't notice him re-wearing the one hoodie that "hides it." Wondering if this was something we needed a dermatologist for. It's a wipe. He uses one before bed and stays dry through school AND practice — one wipe lasts up to 7 days. It's the same active ingredient dermatologists recommend for excessive sweating, at 15%. $19.99 and a 100-day money-back guarantee. Cheaper than the shirts I was replacing.
