How to tell an antiperspirant from a deodorant by its ingredients

Words on the pack such as “deo”, “freshness” or “48 hours” do not always tell you which category a product belongs to. The ingredient list is more reliable: an aluminum salt in the INCI means an antiperspirant that reduces sweating; without one, the product only deals with odor. A combined product may do both.

What deodorant does

Sweat itself usually has very little odor. Odor develops when components of sweat interact with bacteria on the skin. A deodorant helps control odor through fragrance, antibacterial ingredients or a combination of the two, but it does not necessarily reduce wetness.

What antiperspirant does

Aluminum salts temporarily reduce the release of sweat through the ducts in the treated area. That is why the active ingredient, application area and directions matter more in a product profile than the word ‘freshness’.

How to choose

If odor is the only concern, a deodorant may be sufficient. If wet marks or pronounced sweating are the issue, comparing antiperspirants is more relevant. Completely dry skin and a thin layer are especially important with long-lasting overnight products.

OKEY is an antiperspirant, not a deodorant

OKEY is made by the team that owns this site. By the classification in this article it is an antiperspirant: its active is aluminium chloride in a water solution, which reduces sweating in the treated area. OKEY contains no fragrance, so it does not mask odour with a scent, and it contains no alcohol either. It is a 35 ml roll-on for women and men with care ingredients: aloe vera, panthenol, hyaluronic acid, chamomile extract, allantoin and glycerin. It is applied in the evening to clean, completely dry, unbroken skin, left on overnight and washed off in the morning; the claimed duration is up to 72 hours. You can try OKEY via the official site okeystaydry.com or the Kaspi link below; if the product doesn’t suit you, the bottle can be returned within 14 days.
