Is this deodorant safe for sensitive, acne-prone, or dry skin?

The mineral base of potassium alum is generally gentle and can be suitable for acne-prone or dry skin, but the presence of fragrance, farnesol and silicone ingredients means that very sensitive individuals should patch test before regular use.

What is the role and benefit of potassium alum in this deodorant?

Potassium alum acts as a natural astringent that reduces sweat odor by inhibiting odor-causing bacteria and by temporarily tightening the skin, providing deodorising action without blocking the sweat glands.

How often should the deodorant be applied and does it contain any controversial chemicals?

Apply the product to clean, dry underarms once or twice daily as needed; the formula includes dimethicone, cyclopentasiloxane and polysorbate 60, which are approved for cosmetic use but are sometimes avoided by consumers who prefer silicone-free or preservative-free products, and it also contains the fragrance allergen farnesol.
