Why is Mitochondria Trending in Skincare?

‘Mitochondria’ is one of the things from school that stays surprisingly clear in memory. The powerhouse of the cell, once a textbook definition, now finds its way into skincare with a cellular, longevity-focused perspective. Dr Zoya Diwan, director of Trikwan Aesthetics, London, explains that mitochondria are the 'energy centres' of cells, producing ATP to support collagen production, cell turnover, and repair in the skin. They also regulate cell survival and DNA integrity, helping skin respond to UV and environmental stress. Multiple studies show that optimal mitochondrial function improves skin structure, hydration, and resilience. Dr Eugenia Bonelli, a board-certified doctor specializing in aesthetic medicine, notes that mitochondrial decline leads to reduced collagen synthesis, slower regeneration, impaired repair mechanisms, and visible signs of ageing like dullness, fine lines, and loss of elasticity. Oxidative stress, chronic inflammation, and mitochondrial damage accelerate cellular ageing. ROS damage mitochondrial DNA, proteins, and membranes, creating a vicious cycle that reduces energy production and increases inflammation. This cycle manifests as increased sensitivity, uneven texture, and overall skin quality decline, including in conditions like rosacea and pigmentation. Experts highlight that mitochondrial health supports ingredients like vitamin C, vitamin E, polyphenols, Co-Enzyme Q10, niacinamide, resveratrol, and L-carnitine, which reduce oxidative stress and support cellular energy pathways. While topical skincare can influence superficial skin layers, systemic factors like nutrition, sleep, and hormonal balance also play a crucial role. This approach is particularly beneficial for skin showing early signs of ageing, such as dullness and reduced resilience, especially in those with high environmental exposure or chronic stress. The science underscores the importance of mitochondrial health in skincare, though it should be part of a broader approach to skin health rather than a standalone solution.
