Honey, skin and wounds

Medical-grade honey is a regulated product

Honey-based wound dressings are licensed as medical devices in a number of countries and are used in clinical practice for certain wound types. Several are Leptospermum-based. They are gamma-irradiated to eliminate microbial contamination including Clostridium spores, produced to a controlled specification, and applied under professional supervision.

The rationale is plausible and mechanistically coherent: high osmolarity draws fluid from the wound bed, low pH may assist healing, and antibacterial activity — peroxide-based in most honeys, methylglyoxal-based in Leptospermum honeys — acts at the surface where the honey actually is. The clinical evidence is mixed by wound type and generally of low to moderate certainty. It is a legitimate option in some contexts rather than a demonstrated superior treatment.

Why the kitchen jar is different

Honey in cosmetics

Honey is a common cosmetic ingredient and the reason is uncontroversial: it is humectant, meaning it attracts and holds water. That is a direct consequence of its sugar concentration — the same property that makes an open jar absorb moisture from a damp kitchen — and it is a sensible thing to put in a moisturiser. Applied to intact skin as a face mask or in a formulated product, it is generally safe for most people.

Honey is also sticky, sugary and will feed skin-surface organisms, which is a reason for caution in acne-prone skin rather than an argument for it. Allergic reactions are uncommon but do occur, particularly in people sensitive to pollen or bee products, and a patch test is sensible before putting any food on a face. Propolis, which is often sold alongside honey for skin use, is a more frequent contact allergen than honey itself.
