Worth contacting them, they’re still downplaying this now so I imagine there may potentially be more issues with other batches/products.
My underarms are scarred. I had to wear sudocrem and I’d come home from work in pain and cry. For weeks! Even after I stopped using it because I suspected really quickly it was the antiperspirant. I’m so pissed off they’re still downplaying this as ‘irritation’ when many of us had fucking chemical burns.
