Thick or thin sun protection clothing blocks UV rays better?

The thicker the sun protection shirt, the better it blocks UV rays, protects the skin from the sun and protects it better, is that right? (Suong, 22 years old, Dong Nai ).

Reply:

A good sun protection shirt does not depend on how thick or thin the shirt is, how many layers you wear, but on the material. This is an important factor in choosing a good sun protection shirt.

Specifically, shirts made from jeans, cotton, and shirts with a high-sun protection nano coating all prevent UV rays from damaging the skin. Many shirts are made from specialized sun protection materials, with skin-soothing active ingredients, helping to prevent skin irritation upon contact.

In case of naked eye observation, you can check the coverage level through the distance between the fabric fibers. The tighter the fabric fibers are woven together, the less gaps there are, the better the fabric quality, the higher the sun protection ability will be.

You can expose the fabric to the sun. If the sunlight penetrates too much, the fabric fibers will be sparse, and the level of sun protection will decrease. In addition, you can choose dark-colored shirts to help block UV rays, which are more effective at blocking the sun than light-colored shirts.

However, you should not depend on clothing but need to combine many methods such as fully covering up when going out, avoiding rush hour, applying sunscreen, and taking sunscreen pills.

You should choose a quality cream that is suitable for your skin area and skin type (oily skin, dry skin, sensitive skin...). The rule for applying cream is to apply it at least 20 minutes before going out in the sun, and reapply it after two to three hours. Prioritize areas that are directly exposed to sunlight. If possible, apply sunscreen to your arms, legs, and body. You should apply sunscreen even when indoors.
