The Role of Coenzyme Q10 in Skin Aging and Opportunities for Topical Intervention: A Review.

BACKGROUND

Coenzyme Q10 (CoQ10) is a naturally produced, lipid-soluble molecule crucial for cellular energy production and antioxidant activity. It diminishes with age and under external stress factors in skin, leading to signs of aging. Beyond its role in cellular energy production within the mitochondria, CoQ10 is vital to skin's defense against oxidative stress, a key contributor to premature aging. Use of topical skincare products with CoQ10 can be effective to replenish levels of CoQ10 and reverse skin aging.

OBJECTIVE

This publication discusses the role of CoQ10 in skin aging along with the benefits of topical skincare products that incorporate CoQ10 as an ingredient.

METHODS

We searched the PubMed database using terms "Coenzyme Q10" and "skin" and "aging." Overall, the search yielded 80 results, but a limitation of 10 years was then applied to restrict publications to those with the most up-to-date science.

RESULTS

A total of 36 publications were identified and included as background for this article. These 36 publications encompassed both original research articles and review articles.

DISCUSSION

Applying topical skincare products with CoQ10 replenishes CoQ10 cellular levels, helping to normalize cellular energy homeostasis and providing antioxidative effects to support and repair cutaneous damage including signs of skin aging. In and studies, application of CoQ10 increased CoQ10 levels both on the skin surface (i.e., stratum corneum) and even more in deeper levels of the skin. Clinically, topical application of CoQ10-formulated products reduces the depth of cutaneous wrinkles, a sign associated with aging.

CONCLUSION

Aging and stressed skin are, in part, the result of alterations in cellular metabolic homeostasis, which can be reversed via the benefits of topical application of CoQ10-enriched formulations that stimulate cutaneous energy metabolism and reduce free radicals via antioxidant function. By restoring physiological homeostasis, topical skincare products with CoQ10 replenish the skin's antioxidant levels, increase cellular (energy) metabolism, and reduce the signs of skin aging.
