Is this deodorant spray suitable for sensitive, acne prone, or dry skin?

The alun provides a drying antiperspirant effect that can be beneficial for oily or acne prone skin, but the presence of benzyl alcohol and the mineral alun may exacerbate irritation or dryness in highly sensitive or already dry skin, so a patch test is recommended.

What role does potassium alum (natural alun) play in this deodorant?

Potassium alum acts as a natural astringent that temporarily blocks sweat ducts, reducing perspiration without the use of aluminum chlorohydrate, and it also has mild antibacterial properties that help control odor.

Q: How often should the spray be applied and does it contain any controversial chemicals?
