Peer-reviewed literature indicates that sun exposure is responsible for the vast majority of skin aging and photoaging, which specifically includes the development and deepening of wrinkles.
Introduction Korea is located between Japan and Mainland China. The people of these three countries have similar appearances and it is difficult to differentiate between them. Although the population of Asia is more than half of the total population of the Earth, the inherent characteristics of Asian skin have not been well investigated. Commercial markets for cosmetics and drugs for photoaged skin are rapidly expanding in many Asian countries. Therefore, many investigators in the field of dermatology and cosmetology have become interested in brown Asian skin. Clinical characteristics of skin aging and photoaging in Asians Skin aging can be divided into two basic processes: intrinsic aging and photoaging [1]. Intrinsic aging is characterized by smooth, dry, pale, and finely wrinkled skin, whereas photoaging, which indicates premature skin aging in chronically photodamaged skin, is characterized by severe wrinkling and irregular pigmentation. The pattern of wrinkling in Asians seems to differ from that in Caucasians. Asians have coarser, thicker and deep wrinkles, particularly in the forehead, perioral and Crow's foot areas. In contrast, Caucasians usually have relatively fine cheek and Crow's foot wrinkles. The reasons for these differences are not known and need further investigation. There are racial, ethnic and genetic differences, and differences of skin structure and function, between the brown skin of Asians and the white skin of Caucasians. As Asian skin is more pigmen
Photo aging is becoming increasingly interesting, as it causes, among other alterations, the appearance of wrinkles, pigmentation disorders and loss of normal skin tone. Exposure to sunlight is responsible for 80 to 90% of facial aging. Signs of photoaged skin include changes in skin color, dyschromia’s, lentigos, gradual appearance of telangiectasias (dilation of small blood vessels), as well as changes in skin texture such as loss of smoothness, keratotic appearance, early development and deepening of wrinkles.The aging of our skin is not only the result of the passage of time. It is also strongly influenced by external factors, such as weather conditions. The skin is made up of three layers: the epidermis, or outer layer, the dermis, or middle layer, and the subcutaneous tissue, or deep layer. The dermis contains collagen, elastin, and other fibers that make up the skin’s structure. These elements give the skin a smooth and youthful appearance, and these are those damaged by Ultraviolet Radiation (UVR). UVRs are made up of two different types of waves, UVA and UVB. When UV rays hit the skin, the melanocytes struggle to produce melanin to deposit in the epidermis. This is the process that gives you a tan, which is actually a defense reaction against radiation so that it does not penetrate the skin. UVB rays are shorter than UVA rays and are the main cause of sunburn. UVA rays are responsible for much of the damage we associate with photoaging. UVA rays penetrate deep into t
