The aging of the human body is most easily reflected on the skin, and the culprit of skin aging is not natural aging, but caused by more terrible photo-aging. In daily skin care routines, the most important thing about sun protection is to prevent photo-aging!
The harmfulness of ultraviolet rays to human health is receiving people’s attention. In recent years, the incidence of various types of skin diseases induced by sunlight and ultraviolet rays has increased exponentially. Such as: sunburn, photosensitive dermatitis, chronic actinic dermatitis, skin porphyria. Solar keratosis, malignant melanoma, etc.
There are two types of skin aging: internal and external
1. Intrinsic aging, also known as natural aging, is determined by individual genetic factors.
2. External aging is mainly caused by light aging. Ultraviolet rays are the most important factor, so external aging is generally defined as light aging. In addition, smoking, smog, exhaust, pollution, etc. can accelerate skin aging.
What is light aging of the skin?
After 30 years of age, our face begins to have many problems, such as: abnormal pigmentation (age spots, solar freckles, etc.), loose skin, fine wrinkles, no redness, enlarged pores, dull skin color, etc. This shows that these changes in our face are not aging in the true sense. Dermatology calls this aging as photo-aging. It means that light promotes the premature appearance of aging changes in the skin. Skin aging outside is photo-aging. It is mainly caused by ultraviolet radiation. Appears as rough skin. Thicken, loose, deep and thick wrinkles, local hyperpigmentation or telangiectasia, and even various benign or malignant tumors.
