Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a mild repairing skin brightening sunscreen and a preparation method thereof. Background technique [0002] Sunscreen is a skin care product that uses the principle of sunscreen to protect the skin from ultraviolet rays, thereby avoiding the production and accumulation of melanin. It is applied on the skin to prevent sunlight from contacting the skin. The main difference between sunscreen lotion and sunscreen lies in the physical properties. Creams generally have a water content of about 60%, which looks thicker and paste-like; while emulsions, with a water content of more than 70%, look thinner and have fluidity. . According to different sunscreen principles, it can be divided into inorganic sunscreen and organic sunscreen. Among them, inorganic sunscreen is mainly based on reflection, and organic sunscreen is mainly based on absorption. [0003] Sunscreen products ...

AI Technical Summary

Problems solved by technology

[0004] Sunscreen wraps the skin by forming a thin film on the surface of the human skin, absorbs ultraviolet rays, and undergoes a chemical reaction with it to change into other substances, thereby offsetting the damage caused by ultraviolet rays and reducing the impact of direct sunlight on the skin. Based on this principle, the existing sunscreens are often non-compatible ingredients, and the ingredients cannot enter the skin surface to modify the sunburned part, that is, the existing sunscreens only have simple sun protection and do not have repairing functions.

In addition, because the existing sunscreen ingredients are easily contaminated by microorganisms, the existing sunscreen lotions all contain high levels of preservatives, but preservatives and other ingredients are likely to cause stress on the skin, causing skin inflammation and other side effects
