Deodorants are topical products applied to skin (typically underarms) to reduce or mask body odor, often by inhibiting odor-causing bacteria, neutralizing odor compounds, or adding fragrance; antiperspirant variants also reduce sweat via aluminum salts. They are used cosmetically rather than as a dermatological treatment.

Skin irritation / contact dermatitis | Common | Redness, itching or burning, often from fragrances, alcohol, or aluminum salts. |
Allergic contact dermatitis | Uncommon | Sensitization to fragrance, preservatives, or other actives confirmed by patch testing. |
Folliculitis or skin dryness | Uncommon | Especially with alcohol-based or freshly shaved skin. |
Hyperpigmentation of axillary skin | Rare | Post-inflammatory darkening following chronic irritation. |
Granulomatous reaction | Very rare | Localized granulomas reported in association with aluminum-containing products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
