Cherry juice can assist with skin discoloration, dark spots, and the treatment of rosacea; it can also kill most of the bacteria that causes acne. Cherry kernels contain oils that are used in cosmetic products to assist in the smoothing of skin and sealing in of moisture. Another interesting fact is the antioxidant properties held within cherries that make it a powerhouse when fighting damage from UV exposure and the signs of aging. 
Cherries are considered a great ingredient to assist with inflammation. Chronic inflammation can cause an undesirable change in skin; when inflamed the skin can become cold to the touch, swollen, rough, and it can loose its elasticity. Along with olive oil, blueberries, cruciferous vegetables and ginger, cherries are one of the foods with anti-inflammatory properties that help soothe and heal irritated skin. 
Another characteristic found in cherries is that they are a natural humectant – meaning that they pull water out of the air to moisturize the skin. Therefore, they naturally moisturize the skin, improving the penetration of other nourishing ingredients.
All in all, there is an enormous amount of potential packed into this small, delicious fruit; as the proverb says… "Good things come in small packages."
Recently, Dr. Russell J. Reiter, professor of neuroendocrinology at The University of Texas Health Science Center in San Antonio, put some scientific fact behind myths related to the benefits of eating cherries. Russell conducted a five-month study and found that tart cherries contain significant amounts of melatonin – a hormone produced in the brain's pineal gland that has been credited with slowing the aging process, and fighting insomnia and jet lag. It has also being studied as a potential treatment for cancer, depression and other diseases and disorders. Russell also stated that this finding marks the first time melatonin has been pegged as a naturally occurring substance in food, although trace amounts are evident in bananas, corn and other foods.
