Can regular honey protect the skin from the sun? A new study provides an interesting answer.
Honey has long been known for its antibacterial and anti-inflammatory properties, but now scientists are studying another possible use for it—protecting the skin from damage caused by ultraviolet radiation.
Researchers from the University of Sassari reported that in a laboratory experiment, skin cells pre-treated with a 1% solution of multifloral honey proved more resistant to ultraviolet radiation. They observed reduced activity of genes associated with cellular aging, as well as enhanced intrinsic antioxidant defense.
Why does this matter? Ultraviolet radiation is considered one of the main causes of premature skin aging. Under the influence of sunlight, reactive oxygen species are formed—unstable molecules that damage proteins, lipids, and cellular DNA. Over time, this leads to decreased collagen production, the appearance of wrinkles, pigmentation spots, and loss of skin elasticity.
Honey contains a wide range of biologically active substances, including polyphenols, flavonoids, organic acids, and other antioxidants. It is likely these compounds that help cells more effectively resist the oxidative stress that occurs after ultraviolet exposure. However, the exact mechanism of action has yet to be established.
At the same time, it is important to interpret the study results correctly. The experiment was conducted only on cell cultures in the laboratory, not on humans. This means that, for now, no conclusion can be drawn that applying honey to the skin actually protects it from solar radiation in real-world conditions.
Moreover, honey does not have a proven sun protection factor (SPF) and cannot replace sunscreen. For the prevention of sunburn, photoaging, and reducing the risk of skin cancer, it is still recommended to use broad-spectrum sunscreens with an SPF of at least 30, reapplying them every two hours while in the sun.
Nevertheless, the study is of scientific interest. If future clinical trials confirm the results, components of natural honey could become the basis for new cosmetic or dermatological products aimed at mitigating the effects of ultraviolet exposure and supporting the skin's natural antioxidant defense.
For now, the main conclusion remains unchanged: honey is a promising subject for further research, but not an alternative to modern photoprotection. Combining sunscreen, limiting exposure to direct sunlight during peak hours, and using protective clothing remain the most effective ways to maintain skin health and reduce the risk of its premature aging.
