Definitions
- the present invention relates to a prophylactic / therapeutic agent for skin aging and a therapeutic agent for scarring of the skin.
- Skin aging such as skin wrinkles, sagging / loosening, pigmentation, depigmentation, thinning, and reduced skin viscoelasticity has a significant impact on the quality of life (QOL) of women, If the degree is significant, it may be an obstacle to social life.
- QOL quality of life
- skin aging has been considered to be so-called physiological aging, which progresses with aging.
- most of skin aging has been caused by exposure to ultraviolet rays (so-called photoaging). It is said that it is due to.
- photoaging ultraviolet rays
- the skin aging progresses as described above, such as inflammation, subsequent destruction of the dermal tissue, and functional deterioration of fibroblasts.
- scarring of skin such as keloid has a great influence on the patient's QOL, and depending on the degree and part (face etc.), it may become an obstacle to social life.
- Scars are generated in the following healing processes such as trauma.
- wound healing mechanisms such as bleeding / coagulation phase, inflammation phase, proliferative phase work, epidermising ends after a certain period of time, and scarring matures thereafter Heal after leaving maturity leaving scars.
- scars such as hypertrophic scar, retention contracture, keloid, and atrophic scar skin may occur.
