important.<\/p><p>For example, I often go to Australia, where the UV rays are strong.<\/p><p>Sunscreen, which is more important than when you&#039;re in Japan, isn&#039;t something you can just use any product on.<\/p><p>When choosing sunscreen, the following two things are important:<\/p><p>- It can protect against both UVB and UVA rays.<br \/>- Avoid unnecessary irritation to the skin.<\/p><p>Because I have somewhat sensitive skin, I&#039;ve always had trouble choosing sunscreen.<\/p><p>Even those without sensitive skin may find that sunscreens are generally quite irritating.<\/p><p>Using it every day can unknowingly irritate your skin, which can lead to the formation of blemishes.<\/p><p>Whether you have resilient skin or not, choosing a gentle sunscreen is good for the future of your skin.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3a22ab0 elementor-widget elementor-widget-heading\"

(meaning it doesn&#039;t penetrate deeply), and the stimulation is strong.<\/p><p>UVA<br \/>Ultraviolet rays penetrate deep into the skin, causing blemishes, wrinkles, and sagging.<\/p><p>Because the wavelength is long (meaning it penetrates deeper) and the stimulus is less intense, it is often overlooked.<\/p><p>Both types of UV rays should be avoided as much as possible.
