Are you one of those people who don't wear sunscreen every day? You may have also occasionally heard the downsides of not wearing sunscreen and know it's not good for your skin. So why are you still curious about this topic? It's because the harm of not wearing sunscreen is far more serious than we think.
Not wearing sunscreen can lead to serious skin problems in the long run. In this article, I'll tell you why it's important to use sunscreen and what happens if you don't. Please follow COOSEON to read on to learn more.
Why should I use sunscreen?
The sun can damage your skin more than you might think. If you don't protect yourself with sunscreen, limited skin exposure to the sun can cause irreversible long-term damage.
The sun's rays impair the health of the skin in two main ways. UVB rays accelerate skin aging, while ultraviolet B (UVB) rays burn skin cells. The sun's UV rays can reach your skin when you're out and in your home or car.
"Your skin has its own natural defense mechanisms that protect against UV rays to a certain extent, but protecting skin cells from excessive sun exposure is not enough and can lead to chronic skin problems - skin like blemishes, wrinkles and wrinkles." Vedic General Practitioner and Ayurvedic Physician.
Therefore, it is very necessary for us to use sunscreen every day to effectively protect our skin.
Two types of sunscreens can be applied to the skin: physical sunscreens and chemical sunscreens. Physical sunscreens contain active minerals that reflect and scatter the sun's rays, while chemical sunscreens absorb light before reaching the skin's inner layers.
Ten things that happen when you don't wear sunscreen.
Sunspots may appear after prolonged exposure to the sun. Sunspots are usually accompanied by itching, burning, and stress.
Without sun protection, UV radiation can damage the collagen and connective tissue of the skin. As a result, the skin loses elasticity, leading to wrinkles, sagging, and aging, even in young people.
A study conducted by the National Health and Medical Research Council of Australia found that in healthy middle-aged men and women, regular use of sunscreen reduced skin aging.
Darkening of the skin
The skin produces excessive amounts of melanin to protect itself from the sun. This can lead to darkening and uneven skin color.
Studies conducted by the Department of Dermatology and Venereology, Maulana Azad Medical College, New Delhi, have shown that regular use of sunscreen is very effective in preventing photoaging and hyperpigmentation of the skin.
Skin burns caused by excessive exposure to ultraviolet radiation from the sun are called sunburns. Moderate to severe sunburns appear on the skin as red, burning, painful patches of skin with blisters. After a few days, the burned skin flakes off.
A prospective study of sunburn in young people found that regular use of sunscreen for at least six hours during the summer can proportionally reduce the frequency of sunburn.
UV radiation can cause irreversible damage to DNA, leading to genetic mutations and eventually skin cancer. Skin cancer is the rapid growth of skin cells that form malignant tumors.
A Norwegian study on women and cancer showed that using sunscreen with SPF>=15 significantly reduced the risk of melanoma compared to using sunscreen with SPF<15.
People with lighter skin tones have a higher risk of developing skin cancer, so using sunscreen daily can help reduce this risk.
If new moles, freckles, or brown spots appear on your skin, watch them closely. If the spots do not heal and begin to change abnormally, seek immediate medical attention, as this may be an early sign of melanoma.
Inflammation occurs when skin tissue is exposed to harmful ultraviolet radiation. Inflammation is part of the natural healing process of skin that has been damaged by UV radiation. You will experience swelling, redness, and pain.
When exposed to direct sunlight, skin loses moisture and natural oils. This leads to dryness; over time, dry, rough patches appear in the affected areas of the skin.
A study conducted on Japanese seniors showed that the moisture content of the pink layer of the skin increased significantly after 18 months of regular sunscreen use.
When healed wounds and acne are exposed to the sun, scars can form on the skin. When UV light hits inflamed and healed skin tissue, post-inflammatory hyperpigmentation (PIH) occurs, leaving dark brown scars on the skin.
Studies have shown that broad-spectrum sunscreens are effective against inflammatory hyperpigmentation and melasma.
Do not apply sunscreen to open wounds. Applying sunscreen to a healing wound can cause scars to disappear more quickly.
Damage to blood vessels
UV rays can damage the capillaries under the skin tissue. When a bloody discharge appears on the skin, fluid leaks out of the damaged blood vessels, causing red bumps and blotches on the skin.
Studies have shown that the use of sunscreen can be effective in improving the condition of blood vessels. The use of sunscreen protects the blood vessels from harmful UV rays and prevents them from dilating.
Exposure to UV radiation alters the distribution and activity of certain immune cells in the skin. UV radiation stimulates an increase in cytokines and an increase in T-cell activity. As a result, the immune response of the skin is suppressed.
How often should sunscreen be applied?
It is recommended that sunscreen be applied every two to three hours; many people believe that a sunscreen with SPF 50 or higher will last longer and does not need to be reapplied. However, this is a myth.
"Just because an SPF is high doesn't mean it's a good sunscreen.
Tip: It takes at least half an hour for your skin to absorb the sunscreen. Therefore, it is best to plan and apply sunscreen for at least 30 minutes before leaving home.(Before reapplying, it is best to leave the sunscreen in a cool mini makeup fridge to ensure the most comfortable application experience)
A final note from COOSEON
Most of us probably don't spend much time caring about applying sunscreen, except for some of us who plan to spend the day at the beach. However, while you may not notice any direct effects, the UV radiation from the sun can damage your skin in different ways. Therefore, applying sunscreen from a thermostatic mini skin care fridge every day is an extremely important step in your skin care routine that you shouldn't skip.
