Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds to the skin. This prompts the skin to heal itself, by creating new cells.
In a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.
Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.
Retinoids: These are prescription-strength treatments that help reduce hyperpigmentation, skin discoloration and some skin scarring by increasing skin cell turnover and stimulating collagen ...
Facial rejuvenation is a cosmetic treatment (or series of cosmetic treatments), which aims to restore a youthful appearance to the human face. Facial rejuvenation can be achieved through either surgical and/or non-surgical options. Procedures can vary in invasiveness and depth of treatment.
Lastly, tertiary prevention is the treatment of an existing symptomatic disease process to ameliorate its effects or delay its progress. Such tertiary prevention includes the use of chemical peels, resurfacing techniques (e.g. micro-dermabrasion), ablative or non-ablative laser resurfacing, radio-frequency technology, soft tissue augmentation ...
The use of fish skin with its natural constituent of omega 3, has been developed by an Icelandic company Kereceis. [50] Omega 3 is a natural anti-inflammatory, and the fish skin material acts as a scaffold for cell regeneration. [51] [52] In 2016 their product Omega3 Wound was approved by the FDA for the treatment of chronic wounds and burns. [51]
Rejuvenation technology and its effects on individuals and society have long been a subject of science fiction. The Misspent Youth and Commonwealth Saga by Peter F. Hamilton are among the most well known examples of this, dealing with the short- and long-term effects of a near perfect 80-year-old to 20-year-old body change with mind intact.
