Honey is a bee-derived, supersaturated solution composed
mainly of fructose and glucose, and containing proteins and amino acids,
vitamins, enzymes, minerals, and other minor components. Historical records of
honey skin uses date back to the earliest civilizations, showing that honey has
been frequently used as a binder or vehicle, but also for its therapeutic
virtues.
Antimicrobial properties are pivotal in dermatological
applications, owing to enzymatic H2 O2 release or the presence of active components,
like methylglyoxal in manuka, while medical-grade honey is also available.
Honey is particularly suitable as a dressing for wounds and burns and has also
been included in treatments against pityriasis, tinea, seborrhea, dandruff,
diaper dermatitis, psoriasis, hemorrhoids, and anal fissure. In cosmetic
formulations, it exerts emollient, humectant, soothing, and hair conditioning
effects, keeps the skin juvenile and retards wrinkle formation, regulates pH
and prevents pathogen infections.
Honey-based cosmetic products include lip ointments,
cleansing milks, hydrating creams, after sun, tonic lotions, shampoos, and
conditioners. The used amounts range between 1 and 10%, but concentrations up
to 70% can be reached by mixing with oils, gel, and emulsifiers, or polymer
entrapment. Intermediate-moisture, dried, and chemically modified honeys are
also used.
Mechanisms of action on skin cells are deeply conditioned by
the botanical sources and include antioxidant activity, the induction of
cytokines and matrix metalloproteinase expression, as well as
epithelial-mesenchymal transition in wounded epidermis.
Future achievements, throwing light on honey chemistry and
pharmacological traits, will open the way to new therapeutic approaches and add
considerable market value to the product.
