Pressed from the kernels or pits of the fruit of the peach tree, which originated in China and was brought to the New World in the 16th century by the Spanish, peach kernel oil sinks into the skin easily and helps revive it with a combination of vitamins and polyunsaturated fatty acids. Together, these nutrients may help in making your skin more supple and youthful in appearance. Peach kernel oil contains vitamins A and E as well as a variety of B-group vitamins. Of these, vitamin E is particularly beneficial to your skin as it is an antioxidant, eliminating free radicals, which are harmful by-products of the metabolic process associated with aging. As you get older, your skin becomes papery in texture and less pliable. Using peach kernel oil may help delay this process and maintain the elasticity of your skin because it contains varieties of polyunsaturated fatty acids, or PUFAs, which are associated with skin growth and health.
