Stem cells: delay skin aging and realize facial rejuvenation
Stem cells: delay skin aging and realize facial rejuvenation. Stem cells are anti-aging.
With the improvement of living standards, people’s pursuit of anti-aging has also increased, focusing on facial maintenance, delaying skin aging, and realizing facial rejuvenation. Skin aging is an external manifestation, divided into natural aging and photo-aging, manifested as loss of skin elasticity, wrinkle formation, decreased sebaceous gland sweat gland secretion, decreased collagen synthesis, and the deposition of active oxygen free radicals in the skin.
Stem cell anti-aging: It plays an important role in delaying skin aging and facial rejuvenation, such as promoting angiogenesis in aging skin, preventing photoaging caused by ultraviolet rays, improving skin tissue regeneration and inhibiting melanin formation. Stem cell anti-aging has become A new generation of technology. At present, adipose-derived mesenchymal stem cells (ADSCs) are the most widely used cell types in the field of skin anti-aging.
Exogenous stem cells can activate skin epidermal stem cells, and can also mobilize other stem cells, such as epidermal stem cells in the raised area of hair follicles, to stimulate the secretion of various growth factors. These growth factors mainly include EGF, VEGF, FGF-β, HGF and TGF-β, etc. They can promote angiogenesis, synthesize collagen, effectively protect fibroblasts in the dermis, and reduce oxygen free radicals caused by ultraviolet rays and chemical factors.
At present, there are reports of simple application of stem cell injection, stem cell assisted fat or hyaluronic acid transplantation for facial rejuvenation. Compared with a variety of traditional treatments, stem cells have better long-term anti-aging effects. The clinical application of stem cells can increase patient acceptance.
It has been confirmed that ADSCs have a variety of anti-aging biological properties such as inhibiting cell senescence, repairing damage, and promoting regeneration. Adipose-derived mesenchymal stem cells combined with hyaluronic acid (HA) are injected into the dermis of the skin through a water-light needle injection method. Using this method has less trauma to the normal tissue structure of the body and fewer complications.
The results showed that compared with the injection of HA alone, the facial skin of the patient improved significantly in spots, wrinkles, skin texture, and UV spots after 3 months of treatment with ADSCs combined with HA injection. It shows that ADSCs combined with HA injection can better improve skin aging, and the anti-aging effect of stem cells is better!
Research by Qin et al. found that stem cell conditioned medium has a similar effect on facial rejuvenation, improving skin tone and significantly improving facial melanin index. Another clinical trial found that stem cell anti-aging can improve the satisfaction, skin elasticity and skin hydration of subjects in the acne scar and skin rejuvenation group, and reduce the amount of transepidermal water loss (TEWL), roughness and melanin index.
A randomized controlled double-blind clinical study of KY Seo, adding stem cell conditioned medium to the microneedle radio frequency, the patient’s skin hydration, melanin, erythema index and skin roughness were all effectively improved. Histological examination showed that the dermis The thickness and collagen content increased significantly.
At present, a number of clinical trials on stem cells have been registered for the treatment of scars, facial skin aging, burns and wound healing, skin grafts, scleroderma and other diseases to verify the safety and effectiveness of the use of ADSCs in humans. Related studies have also shown that stem cells have anti-wrinkle effects, and stem cell transplantation has become an ideal method for facial rejuvenation.
Summarize the 3 advantages of stem cells for anti-aging, delaying skin aging, and realizing facial rejuvenation:
①Easy to operate, reduce trauma, and recover quickly;
②It is anti-aging at the root, and the long-term effect is more advantageous;
③Small side effects, safer for long-term use.
