What is the difference between sunscreen and barrier cream and how should I use them? There is no strict definition or difference between sunscreen and barrier cream, they just differ in formulation and function. In general, the primary role of sunscreen is to provide adequate sun protection for the skin, with a wide enough selection of sun protection indexes (SPF and PA) and dosage forms. The main role of barrier creams is to isolate the skin from some external factors such as makeup, dirty air, and UV rays. Most of the barrier creams have some sun protection ingredients, but the SPF is usually not high in order to make its texture more refreshing and comfortable. The choice between sunscreen and barrier cream depends entirely on the individual’s needs. If you need strict protection from the sun, you need to use sunscreen and remember to reapply it regularly to save you from the sun’s harmful effects. If it’s just for daily protection, a barrier cream with a more approachable texture is also a good choice. Can sunscreen be applied around the eyes? I believe that many people who have sunscreen habits have noticed that sunscreen applied around the eyes, or accidentally rubbed into the eyes will sting the eyes, especially if you have just applied sunscreen, there are hands, rubbing is not, not rubbing is not, it is very uncomfortable. Most of the ingredients in the sunscreen that will sting your eyes are chemical sunscreens, which can cause irritation to the mucous membranes, and this is also related to the sensitivity of the individual, the same ingredients, some people feel stronger, some people do not have a special feeling. That’s why some products state that you should avoid using around your eyes. Nevertheless, chemical sunscreens have their unique advantages, such as good sun protection, light texture, no greasy feeling, not easy to clog pores, etc., and are very popular among consumers. So don’t you need sunscreen around your eyes? Undoubtedly, the skin around the eyes needs sun protection too! What should I do at such times? First try to find a sunscreen that does not irritate the skin of their eyes, if the skin is very sensitive, you can choose a physical sunscreen, or do not use sunscreen on the skin around the eyes, but choose sun shades, so that you can protect the skin around the eyes, but also protect the eyes from UV damage, killing two birds with one stone, why not do it! Do I need sunscreen inside too? We all know that the ultraviolet rays in sunlight are divided into 3 types: long-wave ultraviolet (UVA), medium-wave ultraviolet (UVB) and short-wave ultraviolet (UVC). The longer the wavelength, the stronger the penetrating power. In natural conditions, short-wave ultraviolet (UVC) is filtered out past the atmospheric ozone layer and cannot reach the earth’s surface. Medium-wave and long-wave are the UV components we need to protect against. UVB is stronger in energy and can cause sunburn reactions on the skin, but its penetrating ability is not strong, and UVB in general sunlight can be blocked by glass. UVA is weaker in energy, and prolonged exposure will accelerate skin aging and have a synergistic effect with UVB, but UVA has a stronger penetrating ability. People who drive have experience, if the sunlight is very strong, even if there is a glass block, the arms are still hot and sunburned, and even red and tanned. This is because the long-wave ultraviolet light can pass through the glass to shine on people for a long enough time, or can cause damage, especially in hot weather, the heat effect of visible light will also aggravate the UV damage. So, although it is safer indoors, if you want to enjoy sunbathing in front of a sunny window, the time should not be too long. Do I need to remove sunscreen products? There are many types of sunscreen, with different formulas for different skin types and different occasions of use. For people with oily skin, in order to reduce the greasy feeling after application, they generally choose a more refreshing and light texture. Generally speaking, ordinary sunscreen and skin care products like, do not need to remove makeup and special cleaning, the general cleansing products can be removed. For people who travel, go to the beach, go swimming, or sweat a lot, in order to make the sunscreen have a more lasting sunscreen effect, while reducing the inconvenience caused by reapplication, you need to use a waterproof sunscreen. The sunscreen with waterproof properties needs to be cleaned with a makeup remover. We also have the experience that waterproof sunscreen with water and cleanser or even cleansing soap can not be washed off! This time, makeup remover oil can come in handy, the so-called one thing down, can easily make the sunscreen firmly stuck on the skin defeated, restore the feeling of fresh skin.
