If you don’t want to get darker and older, you have to do this 365 days a year!

Sun protection, as the most basic skin care concept, has been deeply rooted in people's minds.

However, there are still some misunderstandings about sun protection, such as: you don’t need to apply sunscreen on cloudy days, because you won’t get tanned without the sun; you can just apply sunscreen and go out immediately...

As a "clear-headed person", I will tell you in detail today~

Myth 1

No need to apply sunscreen on cloudy days

Don't think that there is ultraviolet light only in the sun and not in sunny weather. In fact, the ultraviolet light on sunny days is stronger and more harmful to people, while the ultraviolet light on cloudy days is weaker and less harmful to people. However, this does not mean that you don't need to use sunscreen on cloudy days.

Myth 2:

Sunscreen is effective when applied

As we all know, sunscreen "protects" against ultraviolet rays, which contain ingredients that can scatter or absorb ultraviolet rays. Therefore, the principles of sun protection are divided into two types:

Physical sunscreen: Titanium dioxide, zinc oxide and other ingredients in sunscreen can play a physical sunscreen role, which can reflect and scatter ultraviolet rays.

Chemical sunscreen: Benzene, salicylate, cinnamate and other ingredients are chemical sunscreens that absorb ultraviolet rays first and then release them in a lower energy form. Both forms can prevent ultraviolet rays from directly contacting the skin.

In order to achieve the above-mentioned sun protection effect, sunscreen needs to form a protective film on the skin surface. However, forming a protective film is not effective just by "applying it". It needs to be applied correctly according to different products.

Myth 3:

Just apply a little bit of sunscreen

Many people have this confusion: I apply sunscreen every day, but why am I still as dark as a "ball"? The reason is: you are applying sunscreen the wrong way!

The correct way to apply is as follows:

① Application time: Some sunscreen products take a short time to form a film, and you can go out 2 to 3 minutes after application; while some sunscreen products take a long time to form a film, and it takes 15 to 30 minutes to take effect. Please read the instructions carefully on this point.

② Application method: To form a complete protective film, push from the center to the periphery in the same direction, rather than applying in circles or overlapping in the same place.

③ Dosage: The amount of sunscreen needed is 2 mg per square centimeter of skin. Taking a normal adult face as an example, about the size of a one-yuan coin is needed.

Pigmentation, wrinkles, aging, sagging and red bloodshot are all manifestations of long-term damage to the skin caused by ultraviolet rays when people do not pay attention to sun protection.

Remember, every time you spend in the sun without protection, your skin is one step closer to aging.

So all you fairies, put on sunscreen!
