The aging skin has rough cortex
huge ass , deep and regular skin lines, pigmentation, and loose and atrophied skin. Skin aging comes from many aspects, including physical, psychological, and natural stimuli. It is an irresistible natural phenomenon. However, human aging can be delayed. To delay skin aging, we must first find out the intrinsic factors of aging and choose suitable skin care products.
Free radicals increase Free radicals are unpaired electrons in the human body that have a strong damaging effect on cell tissues and can lead to skin aging. There is a kind of superoxide dismutase (abbreviated as SOD) in the body, which can capture superoxide anion free radicals, protect tissues and organs, and has a significant inhibitory effect on tyrosine activity. But as a person ages, free radicals continue to increase, while superoxide dismutase decreases with age. Excessive free radicals cause pigmentation to skin fibrous tissue, cell tissue and accelerate skin aging, forming age spots and aging the skin.
The ultraviolet rays in the sun can thicken the stratum corneum, harden the cortex, denature the elastic fibers, lose their elastic function, increase the skin free radicals exposed to ultraviolet rays, and accelerate skin aging. Cosmetics production has manufactured SOD-based cosmetics and sunscreen cosmetics based on the physiological phenomena of the skin and the damage caused by ultraviolet light to the human body, as well as the inhibition of tyrosinase activity by SOD and the function of capturing superoxide free radicals in damaged cells. These cosmetics can delay skin aging, reduce pigmentation, reduce the stimulation of ultraviolet light on the skin, thereby delaying aging.
Natural moisturizing factor contains 30% natural moisturizing factor (NMF) in the keratinocyte layer of the skin, which has strong hydrophilic and moisturizing properties. When the environmental humidity is high, the moisture absorption decreases

When the water content of the stratum corneum is less than 10%, the skin will be dry, desquamated or cracked. Therefore, moisture retention is another important factor in cosmetics. The production of cosmetics adds highly hygroscopic substances to skin care products based on the functions and ingredients of skin natural moisturizing factors. This is a moisturizer, and its function is close to the natural moisturizing factor of the skin, making the skin care effect more complete.
