Sunscreen is a common skincare product used to protect** from UV rays. The composition of sunscreen directly affects the effectiveness and safety of the product. When choosing a sunscreen, it's important to know how to read the ingredient list of the sunscreen. Here are some guidelines to help you read the ingredient list of sunscreens and evaluate their pros and cons.
1.UV filters: Start by focusing on the UV filters in your sunscreen. Common UV filters are chemical and physical. Chemical filters, such as abenzone and octinoxate, can absorb UV rays but may be irritating to sensitive skin. Physical filters, such as titanium dioxide and zinc oxide, reflect and scatter ultraviolet light. They are considered a safer option, especially for sensitive skin.
2.SPF and PA Index: SPF stands for the UVB-band (UVB) protection strength of the sunscreen, and PA stands for UVA's protection capacity. The higher the SPF value, the stronger the UVB protection provided by the sunscreen. The PA index is represented by numbers after the + sign and the "+" sign, and the more "+" signs, the better the UVA protection. Therefore, when choosing a sunscreen, you should pay attention to the SPF and PA index values, and choose the appropriate sunscreen according to your own needs.
3.Phenylbenzimidazole sulfonic acid: It is a UV B-band absorber commonly used in sunscreens. It has good stability and compatibility with cosmetic formulations.
4.Antioxidants: Antioxidants play a role in sunscreens to protect** from UV rays and free radical damage. For example, vitamin C (vitamin C), vitamin E (vitamin E), etc., all have good antioxidant capacity.
5.Plant extracts: Sunscreens may contain plant extracts, such as aloe vera, green tea, etc. These ingredients can help soothe and moisturize**, but some people may be allergic to certain botanicals, so be aware of your own sensitivities.
To sum up, the quality of sunscreen is related to many factors, such as the type of UV filter, SPF and PA index, whether it contains antioxidants and plant extracts, etc. Choose the right sunscreen for your skin type and your need for sun protection. Reading the ingredient list and understanding what these ingredients do is one of the key steps in choosing a sunscreen, and hopefully these guidelines will help you make an informed decision when buying sunscreen.
