Compound in Citrus Fruits May Ward Off Sun Damage to Skin
A new study shows hesperidin, a flavonoid in citrus fruits, can help prevent skin aging and damage caused by the sun’s ultraviolet B (UVB) radiation. The protective effect guards against wrinkles, inflammation and skin thickening.
What if there was a nutrient-dense “superfood” that was so incredibly rich in vitamins, minerals, amino acids and other micronutrients, that it could nourish your body back to optimal health?
Guess what? There is such a superfood out there!
Earlier studies show hesperidin has immunity enhancing, anti-inflammatory and antioxidant properties. Some research also suggests it may have anticancer activity, and its antioxidant action may protects skin cells from UVB damage and cell death.
Hesperidin Reduced Wrinkles, Inflammation and Skin Thickening
In the current study, hairless mice were divided into three categories: a control group, a group exposed to UVB radiation and treated with hesperidin, and a group exposed to UVB radiation but not treated. Mice in the hesperidin group were given water containing 100 milligrams/kilogram body weight of the flavonoid daily. The two groups with UV exposure were irradiated once every 48 hours for 12 weeks, with the dose of radiation gradually increasing.
Results showed the mice that received the hesperidin treatment had reduced depth and length of wrinkles, along with less skin thickening. This means the flavonoid effectively decreased water loss from the skin and improved enzyme functions that are diminished through the sun’s drying effect. In addition, the skin inflammation typically associated with UVB-radiation was reduced. The study was published in the journal BMC Complementary and Alternative Medicine.
Eat Citrus Fruits to Get Hesperidin
Despite concentrated citrus juices having higher hesperidin content, eating whole fruits is still preferable to drinking juices so that you can also consume extra fiber (plus the fiber can help prevent a spike in blood sugar).
Foods that contain the highest hesperidin content are:
Other Ways to Protect Your Skin from Excess Sunlight
While some daily sunlight exposure is essential for good health, you don’t want to get enough to cause skin aging and damage. Here are a few guidelines to protect yourself:
- Stay in the shade as much as possible, particularly during 10 a.m. to 4 p.m., when the UV light is most intense.
- Although it may be tempting to wear shorts and tank tops in warm weather, opt for clothing that covers much of the skin if you expect to be in the sun for an extended period.
- Wear sunglasses that block 99 to 100 percent of UVA and UVB radiation.
- Avoid tanning beds and sun lamps like the plague.
- Wear a hat with a 2- to 3-inch brim.
