Today, we will explore the importance of sunscreen and tips for choosing the right one, so that your skin can remain healthy and beautiful under the sun. Sunscreen not only helps slow down skin aging but also prevents tanning, making it an essential step in everyone’s skincare routine. Next, we will delve into the basic knowledge of sunscreen to help you select the most suitable products for yourself.
Why do most people dislike using sunscreen? One reason may be a lack of understanding about sunscreen; many people worry that sunscreen will make their skin feel greasy or fear it may not be compatible with acne-prone skin. In fact, selecting the right sunscreen product can effectively alleviate these concerns.
First, the “SPF” number we often see on cosmetic packaging serves as an indicator of sun protection. The higher the SPF number, the better the protective effect. It’s worth noting that our skin has a certain level of natural sun protection, especially for Asian skin, which typically has a natural protection level of about SPF 7. This means that compared to Caucasian skin, Asians can spend more time in the sun without getting burned.
If you choose a sunscreen with SPF 30, this means that if your skin is exposed to strong sunlight for 10 seconds, it can withstand protection for up to 300 seconds. Additionally, when the SPF value reaches 50, it can provide 93% protection, and any further increase in number offers only a minimal enhancement. Therefore, for general daily use, a sunscreen with SPF 30 is usually sufficient.
Next, let’s pay attention to the texture of the sunscreen. Some products, such as liquid formulas, are especially suitable for oily or porous skin because they are lightweight and easily absorbed. At this point, in addition to the SPF indication, you should also pay attention to another index, the “PA” value, which relates to UVA protection. The higher the PA value, the stronger the protective ability. PA++++ provides ideal sunscreen effectiveness and can effectively combat UVA that causes skin aging.
However, after choosing a sunscreen product, the correct amount of application is crucial. Many people have a habit of using a small amount of sunscreen, which greatly diminishes its effectiveness. It is recommended to use an amount roughly equivalent to the size of a 5 yuan coin each time to achieve the protection indicated on the product. Moreover, based on your daily activities, reapplication is necessary in a timely manner. For example, when going out on the weekends, it is advisable to reapply sunscreen every two hours.
In terms of ingredients, sunscreen products can be broadly categorized into physical and chemical types. Physical sunscreen ingredients, such as titanium dioxide and zinc oxide, reflect sunlight and are suitable for sensitive skin. Conversely, chemical sunscreens may pose allergic reactions, so it’s essential to choose carefully.
Finally, when selecting sunscreen products, you should also consider whether you need additional moisturizing formulas. Generally, sunscreens already contain some moisturizing components, but depending on your skin condition, you can also use them in conjunction with toners or serums. Sunscreen is an indispensable part of skincare; making the right choices and applying it correctly can thoroughly protect your skin and delay aging. Let’s work together to protect our skin and embrace the sunshine each day!
