Breakthrough Molecules Shield Skin from Sun’s Aging Grasp
11/23/2021
Scientists led by Professors Matt Whiteman and Uraiwan Panich discover two molecules, AP39 and AP123, capable of combatting skin aging caused by UV radiation. These compounds, penetrating deep into skin cells, rejuvenate mitochondria, activate protective genes, and halt collagen degradation, promising a new frontier in skincare and potential medical applications.

In the eternal quest for the elixir of youth, scientists have uncovered a promising path: two novel molecules capable of staving off the relentless march of time etched into our skin by the sun’s rays. This groundbreaking research, spearheaded by Professor Matt Whiteman at the University of Exeter Medical School and Professor Uraiwan Panich at Mahidol University, Thailand, heralds a potential revolution in skincare – one that could rewrite the aging narrative for millions.
Picture this: a radiant summer day, the sun’s warm embrace beckoning you outdoors. Yet, beneath its golden glow lurks an insidious force – ultraviolet radiation. Sunburn, the telltale sign of overexposure, isn’t merely a temporary discomfort; it’s a harbinger of premature aging and a primary catalyst for skin cancer. But fear not, for science has unveiled a glimmer of hope amidst the sun-drenched landscape.
At the heart of this discovery lie two extraordinary molecules: AP39 and AP123. These tiny titans, armed with the power of hydrogen sulfide, possess the remarkable ability to shield our skin from the aging onslaught triggered by UV light. Unlike conventional sunscreens that merely skim the surface, these compounds penetrate deep into the skin, fortifying it against the ravages of ultraviolet A (UVA) radiation.
UVA, the silent assailant, penetrates beyond the superficial layers, wreaking havoc on our skin’s very foundation. It activates collagenases, enzymes that mercilessly degrade collagen, the scaffolding of youthful skin. The result? Wrinkles, sagging, and a premature farewell to our skin’s former glory. But fear not, for AP39 and AP123 emerge as formidable defenders, intercepting UVA’s assault before it can inflict irreversible damage.
But how do these molecules work their magic? It’s all in the mitochondria, the powerhouses of our cells. When stressed by UVA exposure, our skin cells’ energy production falters, setting off a chain reaction of aging. Yet, AP39 and AP123 swoop in as mitochondrial superheroes, supplying a vital alternative fuel: hydrogen sulfide. This fuel injection reignites the cellular engines, restoring balance and vitality to our skin’s inner workings.
Moreover, these compounds trigger a cascade of protective mechanisms within our cells. PGC-1α, the guardian of mitochondrial number and energy equilibrium, springs into action, bolstering our skin’s resilience. Meanwhile, Nrf2, the sentinel of cellular defense, rallies a battalion of protective genes, thwarting UVA’s assault and halting the production of collagenase. The result? Youthful vigor preserved, wrinkles subdued, and the march of time temporarily halted.
What sets AP39 and AP123 apart from their skincare predecessors is their ability to venture beyond the skin’s surface, delving deep into the cellular battlefield where the real skirmish unfolds. While traditional sunscreens may shield us from sunburns, these molecules wage a war on aging at its core, offering a tantalizing glimpse into a future where age is but a number.
The implications of this research extend far beyond the realm of cosmetic rejuvenation. From preventing skin cancers to combating UV light allergies and rare hereditary skin diseases, the potential applications are vast and far-reaching. Moreover, the ongoing development of newer, more potent molecules by MitoRx Therapeutics signals a promising future for clinical skincare interventions.
As we bask in the warm embrace of the sun’s rays, let us embrace this groundbreaking discovery with cautious optimism. While the quest for eternal youth may remain elusive, the journey towards healthier, more resilient skin beckons us forward. With AP39 and AP123 leading the charge, we stand on the cusp of a new era in skincare – one where the sun’s aging grasp is no match for the resilience of the human spirit.
