Apple Polypenols Associated With Reduced UV Radiation Skin Pigmentation
UV rays, either from the sun or from artificial sources such as tanning beds, can cause sunburn. Exposure to UV rays can result in premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, and liver spots. A recent study has found that supplementation with apple polyphenols may help reduce UV radiation induced skin pigmentation.
Sixty-five women between the ages of 20 and 39 participated in the study. They received 600 mg of apple polyphenols, 300 mg of apple polyphenols, or a placebo daily for 12 weeks. The researchers exposed a portion of the participants’ upper arms to solar-stimulated UV radiation. Skin color lightness and melanin formation were measured at baseline, weeks 1, 2, 3, 4, 6, and 10. Facial skin conditions were assessed at baseline, weeks 4, 8, and 12.
Participants who received the apple polyphenol supplements saw less skin reddening following UV radiation, compared to the placebo group. They also had less skin darkening and less melanin formation. No significant differences were seen in facial skin conditions.
The study was conducted by researchers from Fukushima University. It was published online ahead of print on April 13, 2020 in the journal Nutrients.
