Abstract

The invention provides a photo damage resistance gel containing salidroside. A cosmetic contains 5-50 percent of a salidroside lipid nano-emulsion and is capable of resisting damages to skin caused by environment (such as ultraviolet rays and air pollution) except the effects of repairing, moisturizing, resisting wrinkle and refirming. According to the photo damage resistance gel, with the lipid nano-emulsion as a carrier of eliminating the salidroside, serving as the bioactive components of free radicals in vivo, the absorption ratio of skin to the salidroside and the bioavailability of hydrophilic molecules are remarkably increased; with the combination of the salidroside lipid nano-emulsion, a non-bioactive sun-screening agent and a whitening agent, damage of the free radicals to the skin is effectively eliminated while the skin is protected from ultraviolet radiation, and the purposes of protecting the skin and resisting photo damage are achieved.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a salidroside-containing anti-photodamage gel. Background technique [0002] The ultraviolet rays in the sun are the main cause of skin darkening and aging, and it is usually protected against ultraviolet rays by applying sunscreen to the skin. Sunscreen works by shielding the skin from ultraviolet rays, thereby preventing sunburn. At present, sunscreen products on the market are mainly composed of sunscreen agents, and there are relatively few whitening and antioxidant ingredients. [0003] Rhodiola rosea (Rhodiola rosea) is a perennial herb of the genus Rhodiola in the Crassulaceae family. Rhodiola rosea has a long history of application. More than two thousand years ago, people on the Qinghai-Tibet Plateau used it as medicine to strengthen the body and resist ill health. environmental impact. Folks often use it to boil water or soak wine to eliminate fatigue or resist the cold in m...
