Isoamyl p-methoxycinnamate

Isoamyl p-methoxycinnamate is mainly made of a fabric with a certain sunscreen effect. The principle of sun protection is mainly occlusion, and it does not have a good effect on ultraviolet rays of a specific wavelength such as UVA. UVA band, wavelength 320 ~ 420nm, also known as long-wave black spot effect ultraviolet light. It has a strong penetrating power and can penetrate most transparent glass and plastic. More than 98% of the long-wave ultraviolet rays contained in sunlight can penetrate the ozone layer and the cloud layer to reach the surface of the earth. UVA can directly reach the dermis layer of the skin, destroy elastic fibers and collagen fibers, and tan our skin, and produce wrinkles and fine lines. Leaves skin aging. This is medically called photoaging. In the energy distribution of ultraviolet light in sunlight, UVA is 15 times that of UVB, which is the main cause of skin tanning. It reduces the amount of hyaluronic acid in the skin combined with water, makes the skin dry, accelerates the formation of melanin, darkens the complexion, and is also an important cause of skin cancer.
