Sunscreen is mainly divided into the following three types:
1. Physical sunscreen: also known as mineral sunscreen, mainly composed of mineral particles such as zinc oxide and titanium dioxide. These particles can reflect and scatter ultraviolet rays, thereby blocking their entry into the skin. Physical sunscreen forms a protective film on the surface of the skin, providing physical isolation. It is suitable for sensitive skin and children, and is not prone to allergic reactions, but may feel heavy and greasy.
2. Chemical sunscreen: The main ingredients are organic compounds such as benzophenone and benzophenone. These compounds are capable of absorbing ultraviolet radiation and converting it into thermal energy, thereby reducing the damage of ultraviolet radiation to the skin. Chemical sunscreen is transparent and easy to apply, with a lightweight texture that is suitable for daily use. However, some people may be allergic to the chemical components, so special attention should be paid when choosing.
3. Blended Sunscreen (also known as Physical Chemical Combination Sunscreen): It is a combination of physical and chemical sunscreen, containing both mineral particles and organic compounds. Mixed sunscreen combines the advantages of two sun protection methods, which can physically isolate ultraviolet rays and chemically absorb ultraviolet rays, providing comprehensive protection. It is suitable for various skin types, can effectively protect the skin from UV damage, and has a relatively good skin feel, with a wide range of applications.
Sunscreen can be divided into three types based on its main ingredients and sun protection mechanisms: physical sunscreen, chemical sunscreen, and mixed sunscreen. When making a choice, comprehensive consideration should be given to factors such as skin type, skin tone, activity location, and sunlight intensity.
