WAYNE, N.J.—Mitochondria, one of the key players in cellular energy, have received some scientific attention recently, raising questions about its role not only in cellular energy but skin health (J Cosmet Derm. 2010;9(2):122-131). Technological advances in microscopy and development of new and specific fluorescent dyes for visualization of mitochondrial dynamics in living cells have facilitated a newfound interest in these organelles, which are now implicated in diverse cellular functions crucial in health and disease. In a review conducted by ISP Corp., researchers noted: “Mitochondria play crucial roles in several age-related diseases, and in the physiology of normal aging. In this review, we discuss the structural and functional aspects of mitochondria and their implications to the aging process, as well as its significance to skin aging. Available information on active molecules that can impact the mitochondrial functions and their potential use in skin care products is also discussed, highlighting these organelles as a new focus for anti-aging strategies in personal care.”
