Is sunscreen spray waterproof?

General sunscreen sprays have a certain anti-sweat effect, but their waterproof function is not very good. Of course, if you buy a sunscreen spray specifically with a waterproof effect, that is a different matter.

It is recommended that you do not spray it directly on your face. Spray the sunscreen spray on your hands first and then pat it on your face. Do not spray it directly on your face because the spray generally contains alcohol and spraying it directly on your face will cause damage. If the nozzle sprays large droplets of water, you can only spray it on your hands first and then apply it on your face.

Sunscreen spray is harmful to the skin.

Certain chemicals in spray sunscreen may increase the risk of skin cancer. The latest report from the United States states that some sunscreen products can cause endocrine disorders in the human body and even induce skin cancer due to the presence of certain chemical ingredients. Another study also pointed out that once ultraviolet rays penetrate the skin and come into contact with these chemicals, it may induce some skin problems. However, the Personal Care Products Association in the United States questioned these studies and pointed out that most sunscreen products undergo long-term safety testing before they are put on the market and can provide effective protection for consumers.

In this regard, experts say that if skin care products contain phenol, it will indeed irritate the skin, accelerate skin aging, and even cause cancer. But in our country, most sunscreen products have undergone strict national testing and do not contain phenol; the content of palmitic acid is definitely below the national standard. According to a recent discovery in the United States, zinc oxide, an ingredient in sunscreen spray, releases harmful free radical particles when exposed to sunlight, increasing the risk of skin cancer.

A recent study was conducted in the United States to observe how the various ingredients in sunscreen spray change under the sun. Experts have found that zinc oxide, an ingredient in sunscreen spray, releases harmful particles called "free radicals" when exposed to strong sunlight. Too many "free radicals" can damage human cells and the DNA chains within cells, leading to an increased risk of skin cancer. Although some unqualified sunscreen sprays may increase the risk of skin cancer, the sun protection effect of sunscreen sprays is still very ideal and can prevent ultraviolet radiation from invading at the first time. However, when female friends choose sunscreen sprays, they must choose well-known and qualified products and use them reasonably.

Okay, friends, you know that sunscreen spray has a certain waterproof function.
