Description

Sunscreen skin care product and preparation method thereof

Cross-reference to related applications

The present application claims priority to Chinese Patent Application No. CN201710700857.8, entitled "A Sunscreen Skin Care Product and Its Preparation Method", filed on August 15, 2017, the entire contents of which is incorporated herein by reference. In this application.

Technical field

The invention relates to the field of skin care products, and in particular to a sunscreen skin care product and a preparation method thereof.

Background technique

Prolonged exposure can cause skin damage, which is mainly caused by the effects of ultraviolet radiation (UVR). Skin diseases caused by ultraviolet rays will continue to expand as people age. The short-term effects caused by UVR are mainly manifested as sunburn. The photoactive substance in the skin absorbs UVR for 2 to 24 hours and produces erythema, which is the most common acute UVR effect. This erythema is accompanied by edema, blisters, peeling, and severe systemic symptoms. 280-320nm medium-wave ultraviolet (UVB) is the main component of skin erythema. Long-term exposure to the skin may cause skin cancer and other diseases. According to the US Sunscreen TFM (Experimental Final Monograph) and the National Institutes of Health in the United States, UVB and 320nm-400nm long-wave ultraviolet (UVA) all show to the skin. Carcinogenic, however, the former has a stronger effect; when UVB is present, UVA enhances its carcinogenic effect. With the deepening of the understanding of solar ultraviolet radiation, people are looking for various ways to prevent their harm, and the use of sunscreen cosmetics is the most commonly used and effective method.

There are still unsafe factors in the sunscreen cosmetics synthesized in the prior art. It has been reported that contact dermatitis and cross-allergic reactions have increased due to the increase in the amount of sunscreen used and the number of combined use. The masking agents such as titanium dioxide and zinc oxide do not absorb ultraviolet rays, but have a blocking effect, are easily detached from the skin and lose their effects, and even have the risk of clogging the pores and causing cancer.

In addition, the sunscreen cosmetics synthesized by the prior art have a single effect, and only have the effect of a single sunscreen, and do not have the skin care effects of after-sun repair, moisturizing, anti-oxidation and the like.
