I love your deodorant, but I've developed some redness around my underarms. What can I do?

Sometimes people do get a rash from the deodorant. The most likely cause is irritation from the baking soda. Some people find it helpful to apply a bit of coconut oil or argan oil to the area before applying deodorant to minimize irritation.
Some other tips to reduce irritation:
  • Apply to clean skin
  • Don't use right after shaving
  •  Apply a small amount
  • Squeeze out 1/8"-1/4" per armpit
  • Rub in gently
  • Wash off before going to bed every night
Discontinue use if irritation persists.
