In addition to the positive effects, sunlight also contains UV rays, which cause skin abnormalities such as wrinkles, ageing, reduced immunity to infections, and more dangerous skin cancer. Therefore, the daily use of sunscreen is necessary to help your skin avoid unexpected effects.

2 typical types of sunscreen are physical sunscreen and chemical sunscreen.


Most people know the benefits of sunscreen but think that only when going out on a sunny day is okay, and on shady days you don't need to use it. Ultraviolet rays (UV rays) always exist in the sunlight, not just when it's sunny. Especially on mild, cloudy days, their ability to cause damage is double that of normality. Sunscreen plays an important role in the skin protection process. The benefits to be mentioned are as follows:

Enhance skin health

As mentioned, the main component of the sun as UV rays that damage the skin, too much exposure to the sun will make the skin dark, rough and at risk of skin cancer. Using sunscreen will help you limit the effects of UV rays.

The ingredients in sunscreen such as collagen, keratin and elastin help maintain smoothness and shine for the skin. For those with oily skin, sunscreen can also help prevent acne, thin skin, and revealing small veins.

Prevent skin ageing

According to research, the group of people under 55 years old who regularly use sunscreen reduces the risk of ageing by 24% compared to those who do not use or use it infrequently.

The reason for the difference is that the ingredients in sunscreen act as a "barrier", helping to prevent skin ageing such as wrinkles, pigmentation,... Young skin becomes more central and alive from there.

Protect the skin

Sunscreen is considered a solid shield helping to prevent bad effects on the skin and at the same time limiting harmful substances from cosmetics. All kinds of cosmetics on the market will more or less have chemicals that adversely affect the skin, especially makeup products. Using sunscreen before applying makeup will help reduce the number of chemicals coming into contact with the skin. Additionally, you can use sunscreen instead of foundation, which will help the makeup last longer and also enhance the perfect skin tone.

However, you should not apply sunscreen before applying moisturizer because it will make the skin not absorb the nutrients from the cream. Besides, the sunscreen will be diluted and reduce the ability to protect against the sun.

Reduce the risk of sunburn on the skin

Sunburn (also known as the Sunburn phenomenon) is a condition in which the skin is exposed to UV rays (ultraviolet rays) for too long. Sunburnt skin becomes weakened and sensitive, often experiencing redness, peeling, rashes, and itching. According to a study published in the National Center for Biotechnology Information (NCBI) – a unit of the US National Library of Medicine in August 2008, prolonged sunburn can cause ulcers and complications as well as fatal malignancies.

Therefore, you should use sunscreen every day in combination with sun protection within safe limits. This will help your skin prevent sunburn and tanning. It will also limit the risk of cancer.


SPF and PA are the two main factors to consider when selecting sunscreens as well as evaluating their effectiveness.


SPF - Sun Protection Factor is an index that measures the ability to resist UVB rays on a scale of 1 - 100. According to international standards, 1 SPF can protect skin under the sun for 10 - 15 minutes. According to studies, sun protection will last for a different amount of time depending on your skin tone. Such as:

  • For people with fair skin, 1 SPF provides 10 minutes of protection.
  • For people with medium skin, 1 SPF provides 15 minutes of protection.
  • For people with dark skin, 1 SPF provides 20 minutes of protection.

The higher the SPF number, the higher the time it takes to block UVB rays, helping to protect the skin from sunburn and burning. However, the higher the SPF, the more sticky it tends to be. The cream stays on the skin for too long, combined with secretions and sweat, making the skin prone to ageing and damage. Therefore, you should only consider choosing products with high SPF when you have to be out in the sun for a long time.


PA - The protection factor of UVA is an index that measures the ability to protect against UVA rays from the sun, preventing the ageing process. Unlike SPF, PA is expressed with a plus sign (+). The more plus sign (+) a sunscreen has, the better the UVA protection. Such as:

  • PA+: UVA protection at 40 - 50%, about 2 hours to less than 4 hours
  • PA++: UVA protection at 60-70%, about 4 hours to less than 6 hours
  • PA+++: UVA protection up to 90%, about 8h to under 16h
  • PA++++: UVA protection over 95%, from 16h or more


For sunscreen to be most effective, you first need to learn carefully about how to use sunscreen and the right steps to use sunscreen in your skincare routine.

Always use sunscreen at the last step of your daily skincare routine

Any skincare product used after sunscreen will be less effective, making your skin also absorb the nutrients in the product. Besides, they also reduce the ability of the skin to protect the skin from UV rays present in the sun. Therefore make sure you always use sunscreen at the last step of your daytime skincare routine.

Apply sunscreen 20 minutes before going out

Many people think that the skin is susceptible to damage from the first minutes of exposure to the sun. Therefore, it is necessary to apply sunscreen 20 minutes before going out to protect the skin. This idea is correct, but it is still not enough because depending on the type of sunscreen you use, the time it takes to promote on the skin will be different. Specifically:

  • As for physical sunscreen, you can apply it right before you go. Because this line of sunscreen has an effect as soon as it is applied to the skin, it does not need time to penetrate.
  • For chemical sunscreens, you need to apply 15-20 minutes before going outside to get the best effect.

Moisturizing before sun protection is essential

True to its name, moisturizer works like a film covering the skin to moisturize, hydrate and prevent roughness. The use of moisturizer before applying sunscreen both ensures the effectiveness of the moisturizer and limits harmful agents to the skin. You just need to follow the basic skincare routine such as Washing your face - Balancing your skin - Moisturising - Sunscreen and don't skip any steps. Even if the sunscreen you choose contains moisturizing active ingredients.

Use the right amount of sunscreen

Most sunscreen products do not have detailed instructions on how much to use. Dermatologists recommend that the amount of sunscreen a person should take depends on the type of sunscreen they use and the area of the skin they are protecting. Specifically:

  • For topical sunscreens: usually, when applying sunscreen to the entire face, it will be 1-2 grams, with the whole body will be about 25-30 grams. This amount of cream will also include the ears, neck, and middle of the face so that the face is evenly coloured.
  • For spray sunscreen: the standard dosage will be from 3-4 sprays, forming a layer of cream spread evenly on the skin.

When using, take a small amount of sunscreen on your hand, then dot the cream at many points on the face, combine with your hands and pat it all over the face. Following this rule, you will not worry about leaving white streaks on your skin, causing clogged pores.

You should apply sunscreen every a few hours

The ability of a sunscreen to stick to the skin is not as durable as you think, even though the 24-hour effectiveness of sunscreen is real. By design of conventional sunscreens or moisturizing products containing sunscreen ingredients, they are not intended for swimming or perspiring activities.

The best way is to reapply sunscreen every 2-3 hours. There will be different ways to use long-lasting sunscreen products depending on the type. You can refer to the packaging for the best effect.

Sunscreen is an essential product to help protect the skin before going out. We hope this article will help you choose the right sunscreen for your skin and needs.
