Our straålfriends love us for our deodorants; we're super håppy to have sourced yet another super cool deo option from American shores. The approach with this deo is that underarm odour is treated as a skincare issue, using a unique blend of AHA's to create a low-pH environment where odour-causing bacteria can not thrive 😊
