What is chemical sunscreen? Are you suited to a chemical or physical sunscreen? Mechanism of action, pros, and cons of this sunscreen?
The difference between chemical sunscreens and physical sunscreens has been discussed for years. Accordingly, chemical sunscreens act as a filter, absorbing UV rays and converting them into heat and then release them from the skin before they come into contact with the skin. Meanwhile, physical sunscreens act as a mirror, deflecting UV rays by using certain minerals. And the question is which sunscreen is better for the skin?
Chemical sunscreens use many different ingredients. Each of these ingredients blocks UVA or UVB rays. A good sunscreen is a combination of elements to form a complex that can block UV rays consistently.
The advantage of chemical sunscreens is the light, liquid texture that penetrates the skin and leaves no white marks on the skin. The formula is easy to add more therapeutic ingredients. Chemical sunscreen has better sun protection and can replace makeup liners.
However, chemical sunscreens are more likely to cause skin irritation than physical sunscreens. The irritation index on sensitive skin is also higher when the SPF is higher. You also have to wait 15-20 minutes for the cream to soak into the skin before going out in the sun. Some sunscreens contain unstable ingredients (such as Avobenzone) that can reduce sun protection. Besides, because the mechanism of action of chemical sunscreen is to convert UV rays into heat, it can increase the temperature on the skin’s surface, leading to discomfort with sensitive skin and can cause acne.
With its advantages and disadvantages, chemical sunscreens are more suitable for oily skin.
You must understand that sunscreen is essential for healthy skin and to prevent skin cancer. Skin cancer rates are increasing, and Americans are diagnosed with skin cancer more than all other diseases.

This gives us more choices for daily sunscreen products. So, depending on the type of skin you choose, you should give yourself the right type of sunscreen and use them daily to keep your skin healthy, disease-free and not aging fast.
