In the bright sun, we enjoy the beauty of nature to the fullest, but do you realize that in that seemingly warm and warm sunshine, there is a hidden "killer" that can harm our skin - ultraviolet rays? Today, let's delve into the necessity of sun protection, the serious consequences of not protecting from the sun, and effective sun protection strategies.
1. Reasons for sun protection
-
Protects against the deep layers of UV rays
There are three main types of ultraviolet rays emitted by the sun: UVA, UVB, and UVC. UVA has a strong penetrating power and can reach the dermis layer of the skin, it is like a silent destroyer, and in the long run, it will lead to the damage and loss of collagen and elastin fibers, making the skin lose its elasticity and firmness, wrinkles will gradually appear, and the skin will become loose and rough. Although UVB penetration is slightly weaker, it has strong energy, and a large amount of exposure in a short period of time will cause sunburn, redness, pain, burning and other uncomfortable symptoms.

Reduces the risk of skin cancer
Alarmingly, long-term unprotected exposure to the sun can significantly increase the risk of skin cancer. Skin cancer isn't a far-flung nightmare, it's an extreme manifestation of UV rays that can cause damage to your skin over time. Not only does skin cancer cause physical suffering, but the treatment process is often long and arduous, with a huge impact on quality of life and mental health.
-
Prevents pigmentation and hyperpigmentation
Ultraviolet rays are one of the main culprits in the formation of dark spots. It stimulates melanocytes to become overactive, resulting in a large amount of melanin production and deposition, resulting in problems such as dark spots, freckles, and uneven skin tone. These dark spots are not only aesthetically detrimental, but can also be an outward sign of damage to the skin's interior.
Second, the harm of not protecting from the sun
-
Accelerates the process of skin aging
Under the continuous attack of ultraviolet rays, the elastic fibers and collagen of the unprotected skin gradually break down, and the skin's supporting structure is destroyed, just like a house that has lost its pillars gradually collapses. Skin aging is no longer a passing of years, but a rapid depreciation catalyzed by UV rays, causing the skin to lose its youthful radiance and vitality prematurely.
-
Triggers severe sunburn and inflammation
When we stay in the scorching sun for a long time without sun protection, the skin reacts quickly and shows symptoms of sunburn such as redness, swelling, pain, and peeling. This is not only superficial damage, but can also trigger deep inflammation that interferes with the skin's normal metabolism and repair mechanisms.
-
Weakens the skin's immune function
Long-term exposure to UV rays can cause damage to the skin's immune defenses, making it more susceptible to bacteria, viruses, and other pathogens. The skin, which used to be the body's first line of defense, has become fragile under the ravages of ultraviolet rays, and is prone to various infections and allergic reactions.
3. Effective sun protection measures
-
Choose sunscreen scientifically and use it correctly
Sunscreen is our vital weapon against UV rays. First of all, choose the right sunscreen based on your skin type (e.g., dry, oily, sensitive), activity scene (e.g., daily commuting, outdoor sports, beach vacation), and sun protection needs (e.g., waterproof, sweatproof). Secondly, the amount of application is crucial, and the face usually needs about the size of a dollar coin to achieve the nominal protective effect. Apply evenly and evenly to include areas that are often overlooked, such as the ears, neck and hairline. Apply 15-30 minutes before going outside the house to allow the sunscreen to fully form the film. In addition, reapply every 2-3 hours, especially after sweating or swimming, to maintain effective protection.
-
With the help of the Physical Occlusion tool
Physical coverers such as wide-brimmed hats, sunglasses, parasols and sun-protective clothing provide immediate protection from the skin. Wide-brimmed hats can shield the face and neck from direct sunlight, and it is best to choose hats with a brim width of more than 7 cm. Sunglasses not only protect the delicate skin around the eyes, but also reduce the damage caused by UV rays. Parasols should be selected with UV protection that provides shade for movement when walking. The material and weave density of sunscreen clothing will affect its protective effect, so it is better to choose products that are tightly knitted, have good breathability and are marked with a clear UV protection index (UPF).
-
Plan your travel time wisely
Between 10 a.m. and 4 p.m. is the time when UV intensity is at its highest, try to avoid prolonged exposure to the outdoors during this time. If you must go out, try to find a shady place to walk or stay.
-
Pay attention to the internal tone of the diet
Diet also plays a non-negligible role in sun protection. Eat foods rich in vitamin C (e.g., oranges, strawberries, kiwis), vitamin E (e.g., almonds, avocados, spinach) and antioxidants (e.g., green tea, blueberries, pomegranates), which help neutralize free radicals, strengthen the skin's own defenses, and reduce the damage caused by UV rays.
In short, sun protection is a constant battle for the health and beauty of your skin. We can't ignore the potential threat of UV rays, but build a solid protective barrier for our skin through scientific methods and determined actions. Let's start now and integrate sun protection into every detail of our daily lives, so that our skin can remain healthy and radiant under the care of the sun.
