How to use sunscreen correctly!

 It is known that excessive exposure to sunlight  can cause serious damage to the skin , and these risks range from  skin  burns, sores and tanning , to wrinkles and symptoms of skin  aging   due to damaged  collagen  in the skin.

Therefore, it is important to use  sunscreen , and to take into account that it is used in the correct manner and in appropriate quantities, otherwise there will be no actual protection from the   harmful  rays of the sun . Likewise, these preparations should never be overused  so that the skin does not suffocate excessively, and so that the face does not get a sticky mess that does not bearable.

Luckily, there is an easy way to gauge the right amount of  sunscreen  that will keep  your skin  safe, and make your sunscreen last longer.

In this report, we review a lot of misinformation and misinformation about how to use sunscreen, and explain how to use it in the best way.

What is the importance of using sunscreen?

Using  a protective cream  before going out on a sunny summer day is an absolute necessity in order to protect the skin from sun damage and high heat.

A 2016 study, according to the  NCBI  scientific website, linked frequent exposure to severe sunburn with a higher chance of developing skin cancer  later in a person's life.

One of the most effective ways to protect  skin  is to use a sunscreen that blocks both the sun's UVA  and  UVB rays, according  to the Skin Cancer Foundation .

"By using this lotion we can protect things from building up on the skin, in a way that can increase premature aging  and the risk of skin cancer," dermatologist Irum N. Elias explains,  according to his statements to  Healthline.

However, using the right amount of sunscreen is an important step in reducing these risks.

So what is the appropriate amount of use?

According to the same site, one ounce of sunscreen should be applied to the entire  body  if exposed on a sunny day; Since the head and neck account for 4% of the surface area of ​​the skin, you will need about 0.04 ounces of sunscreen to apply to the neck and face.

According to the Allure website  , that translates to 1/2 teaspoon on the face and neck combined — that's 1/4 teaspoon each — and 1 teaspoon of lotion for each arm and leg, front and back, says dermatologist Ranella Hirsch.

The protective cream should also be reapplied on the face a second time during the day if you spend long hours outdoors throughout the day, according to  Harper Bazaar magazine , because climate factors, sweating  , etc. can wipe the lotion off the face and expose some areas to the sun and its dangers.

Misinformation about how to use sunscreen

When you buy a sunscreen with the words SPF 30 or 50, which is the percentage of harmful chemical sun protection products suitable for going out in the direct sun, you are likely to assume that these creams will give you complete protection from the risks of harmful sunlight, but the Allure website points  out  that This can happen only when applied to the face in the correct manner.

A fully absorbed chemical sunscreen needs to be applied to the skin  30  minutes before going outdoors, dermatologist Dendy Engelman tells  Good Housekeeping , to allow the ingredients to fully adhere to the skin. These sunscreens take effect immediately, and can be applied directly before exposure to the sun, but they must be rubbed in until they completely disappear into  the skin .

The doctor points out the need to adhere to what she called the two-hour rule, which is when sunscreen is applied an hour before going out, you will need to reapply it an hour after going out, given that the condom works effectively within two hours of the individual on the skin, no more.

What about the lips and scalp?

Good Housekeeping notes   that hair helps protect the scalp from the sun to some extent. However, you need more protection than that, especially if you have fine hair.

Since about 10% of melanomas occur on the scalp, it's important to take extra precautions by wearing hats or light scarves, and by applying a sunscreen that specializes in protecting the hair and scalp from the  sun  .

As for the lips, especially  the lower lip  , they are also highly susceptible to skin cancer, because they are exposed to the sun every day, and they are one of the most common sites for basal cell carcinoma and squamous cell carcinoma.

Therefore, it is necessary to use a lip balm that contains sunscreen, and is specially designed to protect against harmful rays in the summer, which usually contains a protection factor of 15 SPF or more.
