Will you avoid getting a suntan if you use a parasol? Buying the wrong one or using it incorrectly will ruin your sunscreen

Sunshade is an essential tool for many people to protect themselves from the sun.

However, many people use parasols

Still find the skin is tanned

This makes people wonder:

Do parasols really protect against the sun?

In fact, the sun protection effect of parasols

Depends on many factors

Correct selection and use of parasols is the key

01

The sun protection principle of parasols

Parasols achieve sun protection through physical shielding and material reflection and absorption of ultraviolet rays . Ultraviolet rays are divided into long-wave ultraviolet rays (UVA), medium-wave ultraviolet rays (UVB) and short-wave ultraviolet rays (UVC), of which UVA and UVB are the most damaging to the skin. UVA can penetrate the dermis of the skin, causing skin tanning and photoaging; UVB mainly acts on the surface of the skin, causing skin redness, swelling and sunburn. The function of parasols is to block these harmful ultraviolet rays and reduce their damage to the skin.

How to choose an effective parasol?

Pay attention to UPF value

UPF (Ultraviolet Protection Factor) is an important indicator to measure the sun protection ability of textiles, indicating the intensity of ultraviolet rays penetrating the fabric to reach the skin . According to national standards, only when the UPF value is greater than 40 and the UVA transmittance is less than 5%, can it be called an anti-ultraviolet product. Therefore, when buying a parasol, you should give priority to products with a UPF value of 50+, which can effectively block more than 98% of ultraviolet rays.

Choose the right material and coating

The material and coating of the parasol also have a significant impact on its sun protection effect. Parasols made of polyester are ideal and have better sun protection than other materials. In addition, parasols with double-layer fabric structure have better sun protection effect than single-layer fabric because double-layer fabric can increase the reflection and absorption of ultraviolet rays. The coating on the inside of the parasol is also very important. The most common ones are black glue and silver glue . Black glue coating can absorb more ultraviolet rays and has better sun protection effect than silver glue coating.

Color and size options

The color and size of a parasol also affect its sun protection. Dark-colored parasols are generally better than light-colored ones because dark colors absorb more UV rays. When choosing the size of a parasol, the larger the umbrella, the better, as it can increase the shielding area and reduce the amount of UV rays that hit the skin from the side. At the same time, the curvature of the umbrella should also be moderate to better protect against UV rays reflected from the ground.

03

How to use a parasol correctly?

Avoid using a parasol as an umbrella

The coating and materials of the parasol have been specially treated to achieve the sun protection effect. If the parasol is used as a rain umbrella, the rain will wash away the sun protection coating and reduce its sun protection performance. Therefore, it is recommended to use the parasol and rain umbrella separately to extend the service life of the parasol.

Pay attention to the maintenance of parasols

During the use of parasols, you should avoid long-term exposure to the sun to prevent the sunscreen coating from aging. At the same time, you should regularly check whether the coating of the parasol is damaged. If the coating is found to be damaged, the parasol should be replaced in time to ensure the sunscreen effect.
