In the rainy days from early morning, the cold wind does not even see the sun emerging behind the dense cloud, and normally, you will not wear sunscreen. However, the relationship between sunlight and UV rays is entirely separate. You can ask any dermatologist about sun protection every day because UV protection is considered optimal and is no exception at any time of the year.
What are UV rays?
The sun emits three types of ultraviolet rays: UVA, UVB, and UVC. Currently, the ozone layer is getting weaker and thinner, many holes appear, capable of allowing high-energy radiation such as UVC rays to penetrate the surface of the earth, lasting damage to the skin. UVB stimulates Melanin metabolism – skin pigmentation darkens the skin. If human skin is exposed to intense UVB will cause sunburn, increasing the risk of skin cancer.
In the winter, there is no sun exposure to your skin. However, UV rays are still visible throughout the eye and cannot be seen by the naked eye.
UV rays penetrate through the thick layer of clouds
No matter how thick the clouds are, ultraviolet rays penetrate up to 80%. UVA rays are always present and can penetrate clouds, glass layers, and penetrate deeper into the skin. UVA damages deep layers of skin, leading to premature aging and an increased risk of skin cancer. Most UVA rays are UV radiation with the highest percentage (up to 97%) of the amount of UVA rays because UVA quickly penetrates the ozone layer.
Currently, on the market, many sunscreen products are compatible with BB Cream, CC Cream or have the effect of lifting the skin tone, your skin is not only well protected from UV rays but also becomes more beautiful and economical more makeup time. Advanced sunscreen with SPF 50+ Lancome UV Expert Tone up Milk Pearly White protects skin from UVB, UVA, and other contaminants on the skin, milk texture suitable for oily skin, combination skin and skin optimal dryness, sun protection, and a light makeup layer to lighten your skin.
The effect of sunscreen
1.Good anti-aging ability
Sunscreen has been shown to have excellent anti-aging properties. According to the analysis, UV rays damage collagen and elastin in the skin, leading to an increase in wrinkles, leading to skin aging and sagging. Unlike other anti-aging products, sunscreens with a UV-protective barrier protect the skin from damage caused by UV rays. Not only that, Dior Prestige Light – in – white product – integrated sunscreen oil gives you a perfect foundation with good coverage, 50+ sun protection index, and also excellent anti-aging thanks to extraction. They are made from natural minerals.
The researchers compared skin aging in 900 men and women in Australia for over four years. They found that people who use sunscreen daily did not have a significant increase in skin aging. Overall, they age 24% less than those who don’t use sunscreen. Therefore, when you want to have healthy and youthful skin, start using sunscreen right now. With hot and humid climate all year round like in Vietnam, CC Cream is the perfect choice to have a light makeup layer, not too thick and highly resistant to ultraviolet rays.
2. Protect skin from blue light
Sunlight is the primary source of blue light, and being outdoors during the day is where most of us are exposed to sunlight. However, there are also many sources of artificial blue light, including fluorescent lights, LEDs and flat-screen TVs, computer screens, smartphone screens. The essence of the anti-aging serum of La Roche-Posay with features to protect skin from UVA and UVB rays will be more convenient for you when using the skincare serum with integrated sun protection.
According to Dendy Engelman, a New York-based dermatologist, pigment cells can be stimulated not only by the sun’s bright UV rays but also by surrounding and infrared doses. The lower is emitted from the computer screen or indoor lights. So even if you’re at home or in the office, you still need to wear sunscreen to protect your skin from artificial blue light. A daily sunblock supplement with zinc oxide and sunflower extract with a sun protection index of 30+ will be an appropriate choice for cold days at home or in the office exposed to blue light.
Sun protection is essential every day, whether you step on the road or not. Ultraviolet rays are everywhere, so is the blue light.
