Sister-owned, Stainky's is committed to creating clean, sustainable, and science-backed personal care products, that work well and feel good to use. Our star product is Pit Prep, an armpit toner that drastically improves the performance of natural deodorants. https://stainkys.com/products/pit-prep Pit Prep eliminates body odor at the source by adjusting the pH of your armpits. This way, your natural deodorant can actually do its job. Alpha Hydroxy Acids, including glycolic acid, lower the pH of your pits so that odor-causing bacteria can't thrive. They also slough away the bacteria's food sources - dead skin and buildup on underarms and underarm hair, leaving your pits fresh and gently exfoliated. Pit Prep works immediately and gets better over time.
