Prolonged sun exposure causes skin ageing, also known as photo-ageing. This leads to changes such as wrinkles, dull skin and increased susceptibility to skin cancer. Despite existing treatments such as retinoids and antioxidants, it is difficult to completely reverse the damage.
New research focuses on the role of mitochondria, the power plants of our cells. Under the influence of sunlight, these mitochondria become damaged and function less effectively. This causes an inflammatory process that contributes to skin ageing. Scientists investigated a mixture of substances derived from special stem cells from the umbilical cord, which are able to repair the mitochondria.
In tests on mice, this treatment restored the function of damaged mitochondria and reduced inflammatory responses. The skin of the treated animals remained firmer, better hydrated and with fewer wrinkles. In cell studies too, skin cells appeared to age less and the treatment contributed to skin rejuvenation.
This discovery is promising because it offers a new way to combat skin degradation at the cellular level. This may provide a more effective approach against skin ageing than current methods. For anyone who wants to age healthily, this could contribute to healthier and more supple skin in the future.
