10-HDA, a natural fatty acid only found in royal jelly, is revealing itself to be of tremendous value when it comes to skin health.
Scientists did several tests on royal jelly. First, they evaluated the activity of 10-HDA on the regulation of skin differentiation markers. They then measured how royal jelly affected the inflammatory response and restored skin barrier function. And lastly, they evaluated royal jelly's effect on xerosis, which is an abnormal dryness of the skin.
What they found was that 10-HDA not only increased skin protein production (new skin growth) but that it was also highly anti-inflammatory. Inflammed skin shows up as red and sore, acne prone, excessively dry and even as a psoriasis or eczema.
They also found that in healthy volunteers with dry skin, the hydration index increased by +28.8% and +60.4% after 7 and 21 days of treatment with a cream containing 10-HDA.
The full study can be found in the European Journal of Dermatology, 2011 September 22.
In another study, scientists examined whether consuming royal jelly daily could influence the hydration levels of the epidermis. The epidermis is the outer most layer of the skin and what we see when we look in the mirror. If you desire to have beautiful skin, your epidermis is vitally important to take care of.
It is also important to know that epidermal hydration is maintained by the epidermal lipid barrier. These lipids provide a barrier against the movement of water and electrolytes as well as a barrier against microorganism invasion. They also stop bacteria and viruses from entering your body through the skin.
During the study, mice were fed a control diet or diets with 1% RJ for 16 weeks. In the control group whom were not fed any royal jelly, epidermal levels of hydration were lower than in the group that received royal jelly. The reason for this suggested the researchers was because of enhanced Ceramide metabolism caused by the royal jelly.
Ceramide is the major component of the epidermis and make up about 20 percent of the skin's intercellular matrix, the glue that holds skin cells together and helps skin maintain its appearance while protecting it. By enhancing the body's ability to metabolize ceramides, royal jelly led to enhanced moisture content and healthier, better looking skin.
