Is it useful to use aloe vera gel to repair after sun exposure?

There is a certain use for using aloe vera gel after sun exposure

Aloe vera gel is a natural negative herb that is cheap and easy to use. After our skin is sunburned, applying a layer of aloe vera gel on the skin can effectively relieve the redness, swelling and dryness of the skin, and it also has an anti-inflammatory effect. It feels cool when applied, which is very comfortable in the summer.

What is the best way to repair after sun exposure?

1. Cool down and calm down

Cooling down can not only reduce the activity of melanin and slow down the rate of skin tanning, but also reduce the stinging sensation caused by sunburned skin. However, skin exposed to the sun is in a burning and sensitive state. If you apply ice cubes directly to your face, or apply a facial mask from the refrigerator, it will bring too strong alternating hot and cold stimulation, and the skin can easily develop allergic symptoms.

2. Soothing and hydrating

Within two or three days after sun exposure, sunburned skin will show symptoms of darkening, dryness, and peeling. This stage is also the golden time for repair after sun exposure. Although whitening after sun exposure is important, the skin at this time is not suitable for whitening products with strong irritation. In addition, since the skin loses a lot of water after sun exposure, and each subsequent functional repair requires that the skin is adequately hydrated, so in the early stage after the skin has calmed, do not rush to whiten it. The most important thing to do is to soothe the skin and increase hydration.

3. Deep repair

If you do not take any care after sun exposure, your skin may develop sun spots and fine lines in about a month. Sun spots are caused by the release of melanin from melanocytes in the skin's epidermis after exposure to ultraviolet rays, thus forming spots; while fine lines are caused by ultraviolet rays accelerating the loss of collagen in the skin, resulting in small fine lines appearing at the tails of the eyes, cheekbones, corners of the mouth, etc.

How to repair small red spots after sun exposure

It may be solar dermatitis, not UV allergy. Don't worry, it will return to normal soon.

Do you need to repair after sun exposure?

1. Sun protection is key before the age of 18

Most melanomas in adults are caused by sun exposure in childhood. Babies under 6 months old should not take beach baths. Children under 7 years old should wear T-shirts, sun hats, and apply children's sunscreen. In the summer, they should try not to go out between noon and 2 pm.

2. People receive sun exposure for about 5,000 hours

According to data, an average person will develop skin cancer after 5,000 hours of sun exposure, but this sun exposure time does not only refer to exposure to the summer sun, but also includes all daily contact with the sun. Therefore, the more times you are exposed to the sun, the more points you will be deducted. When all 5,000 hours are deducted, it will be very dangerous to expose your skin to the sun.

3. Sunburn isn’t the only damage the sun can do to your skin

It is well known that sun exposure can cause spots, wrinkles, and sagging skin, but these are only what we can see with our naked eyes. In fact, it will cause a certain degree of damage to cells and genes. Some cells are killed on the spot, while some injured cells will release a chemical substance that stimulates the capillaries and causes them to rupture, which is what we usually call sunburn. In particular, UVA can penetrate the skin, damage DNA, cause the skin to lose elasticity, and in severe cases can cause skin cancer.

4. It is not the case that the higher the temperature, the stronger the ultraviolet rays

First of all, everyone should clearly understand that ultraviolet rays do not generate heat. For example, when you are at the beach, climbing a mountain or sand skiing, the cooler you feel, the stronger the ultraviolet rays will be.

5. The skin's ability to withstand sunlight varies from person to person, time of day and latitude.

Sunscreens on the market are divided into different grades based on SPF numbers; the larger the number, the longer the protection effect. Usually, the protection time of sunscreen is the SPF number multiplied by 15 minutes. For example, the protection time of SPF 8 is 120 minutes. If you go to the mountains to play, you only need to do general sun protection and choose SPF8 sunscreen. But if you go swimming in the sea, you need to use a sunscreen with SPF15 or above; at noon, when the sun is strong, you need to use a sunscreen with SPF30 or above.

6. SPF30 sunscreen does not protect you twice as much as SPF15 sunscreen

Although SPF30 sunscreen has a greater ability to block UV rays than SPF15 sunscreen, it does not mean that SPF30 sunscreen can block twice as much UV rays. If SPF15 can block 94% of ultraviolet rays, then SPF30 sunscreen can block 97% of ultraviolet rays. Of course, no matter which type of sunscreen you use, you should reapply it every 2 to 3 hours.

7. A parasol won’t protect you from all sunburn risks

In fact, 50% of ultraviolet rays can pass through parasols. They can only isolate UVA (melanin) that causes burning sensation, while UVB (aging factor) can penetrate parasols without difficulty.
