Individuals with kidney disease may need medical advice before use. Keep out of reach of children; misuse or swallowing requires medical attention. User Reports & Common Concerns Skin reactions: Multiple users report itching, redness, burning, even chemical‑burn‑like rashes—sometimes after long-term use or with newer batches.“It felt like sunburn/road rash” and “worst stinging” were common descriptions. Formula changes: Many users believe Old Spice reformulated key ingredients around 2019–2022 (e.g. adding Poloxamine 1307, lowering aluminum levels, removing talc) and report reduced performance and more stickiness or irritation. Performance concerns: Some report modern versions (especially blue‑cap deodorant-only sticks) no longer last a full day or feel less potent than older versions Takeaway Thoughts These stick deodorants are built for strong sweat control and long-lasting scent, but rely on aluminum compounds and fragrance—two ingredients that many users are increasingly sensitive to. Reported skin irritation and chemical burns, even after prior unproblematic use, suggest caution: a patch test is recommended if you have sensitive skin or have experienced reactions from similar products. Many users prefer the white‑cap antiperspirant versions, which tend to offer better performance and fewer irritations vs. the blue deodorant‑only sticks
