CoQ10 has at least two important roles in the body. First, it is one of the essential elements in the biochemical machinery that produces biological energy (ATP) inside the cells. Second, CoQ10 is an antioxidant, helping neutralize harmful free radicals, which are one of the causes of aging.
Under perfect conditions, the body can produce as much CoQ10 as it needs. However, various factors, such as aging, stress and some medications, lower the levels of CoQ10 in the body. As a result, cells have a diminished ability to cope with the stress, and regeneration slows down. Unfortunately, the levels of CoQ10 in the body almost inevitably decline with age. In fact, CoQ10 is regarded as one of the most accurate biomarkers of aging since its decline correlates so well with the aging process.
In some studies, rodents treated with supplemental CoQ10 lived up to 30 percent longer than their untreated counterparts. The effects of CoQ10 supplements on human longevity remain unknown. On the other hand, it was proven useful in treating certain human diseases, including heart failure and hypertension.
In theory, CoQ10 in a cream form can be helpful for the skin. In most people over thirty, levels of CoQ10 in the skin are below optimum, resulting in lesser ability to produce collagen, elastin and other important skin molecules. Therefore, CoQ10 may boost skin repair and regeneration and reduce free radical damage. Furthermore, CoQ10 is a small molecule that can relatively easily penetrate into skin cells.
Even if CoQ10 can be effective in treating skin aging, it is unclear whether popular CoQ10 products contain sufficient concentration of active CoQ10. (Keep in mind that CoQ10, just like vitamin C, can be inactivated by oxygen from the air.). You can get around this problem, however, by preparing your own CoQ10 cream where you can ensure proper freshness and concentration.
