As summer arrives, sun protection should not be overlooked! Do you know how to choose the sunscreen that suits your skin best? Below, we will discuss the types of sunscreens and selection tips to help everyone protect their skin under the summer sun.
The Threat of Ultraviolet Rays
During sunny summer days, ultraviolet rays are still present even on cloudy days. Ultraviolet rays are mainly divided into UVA and UVB. UVA has a longer wavelength and can penetrate deep into the skin, leading to aging and wrinkles. UVB has a shorter wavelength and primarily causes sunburn, resulting in reddened and blistered skin. Prolonged exposure to ultraviolet rays may increase the risk of skin cancer, so it is crucial to take proper sun protection measures.
Physical vs. Chemical Sunscreen
Sunscreen products are mainly categorized into two types: physical and chemical sunscreens. Physical sunscreens contain active ingredients like titanium dioxide and zinc oxide, which can block the intrusion of ultraviolet rays and form a protective layer that works immediately. However, some users may feel that their skin appears white after application, which is due to the reflective layer formed on the skin’s surface by physical sunscreens.
In contrast, chemical sunscreens consist of various ingredients, such as octocrylene and avobenzone. These substances need to be absorbed by the skin and usually take about 30 minutes to start working. Therefore, if you choose a chemical sunscreen, it is advisable to apply it in advance to ensure optimal effectiveness.
Choosing the Right Sunscreen for Your Skin Type
For friends with sensitive skin, physical sunscreens may be a better choice since they tend to irritate sensitive skin less. While lighter sunscreens are less likely to cause acne, some thicker formulations might clog pores and worsen acne issues. Thus, it is key to select a lightweight and non-greasy sunscreen. It must be emphasized that the texture of the sunscreen does indeed affect the emergence of skin problems, especially acne formation.
Sunscreen Tips for Use
When using sunscreen, choose a product that suits your skin type. You should apply two milligrams of sunscreen for every square centimeter of skin, with a recommended amount about the size of a five-cent coin. To maintain optimal protection, it is advisable to replace your sunscreen every month to ensure daily adequate protection.
Remember, whether it’s sunny or cloudy, sunscreen is an important step in protecting our skin. Take good care of your skin and embrace a wonderful summer!
