The truth needs to know about sunscreen

70% of seafarers always leave their lips "naked", while this is an area where malignant tumors are easily formed. Remember to use sunscreen to protect your lips.

>>>The interesting mystery about sunscreen

Applying sunscreen is a therapy that keeps skin youthful and healthy. It can become your daily routine. If you are using sunscreen, read carefully what you need to know below:

There is a difference between sunblock and suncreen

These terms are often used interchangeably, but they actually have differences:

Sunblock is a product line that prevents UV rays from being absorbed into the skin by zinc oxide or titanium oxide. These substances are not absorbed into the skin because they are only on the surface of the skin. So, in order for sunblock to take full advantage, you have to apply a layer evenly, without leaving any place. Advantages: Durable, not penetrating into the skin, so it is good for the skin. However, because you have to apply a thick layer, your face is easily greasy and shiny.

Suncreen is a product line with UV-absorbing substances to neutralize its effects. Advantages: Do not create a white film on the skin so look more natural than sunblock. However, their performance is not durable, so you must regularly add ice cream after 3-4 hours. In addition, the product may cause allergy to sensitive skin.

The choice of cream is depending on the preferences of each person. When using, you should note:

- Using sunblock, you should apply moisturizer first and then on sunscreen (because sunblock is on the surface of the skin, if applied first, it will interfere with the cream to make use)

- Using Sunscreen, you should apply sunscreen first and then nourishing cream (because sunscreen must be absorbed into the skin to work).

- Sunblock is often a better choice for sensitive and irritated skin from chemicals in suncreen.

- Look closely at what is on the label of the product you decide to choose between sunblock and suncreen.

Use concurrent creams

You often think that just using sunscreen is fine, it's not enough. Doctors recommend that you apply an equal amount of lotion to the sun exposure areas on your body and face (equivalent to 2 tablespoons).

Usually use

If you spend most of your time on the street, you need to have a plan to use sunscreen all day

The sun protection effect of the cream takes about 2 hours, so it's best to reapply it after about an hour and a half to 2 hours. Remember, not high SPF cream will work longer but this time period applies to all sunscreens.

Do not think sunscreen can be waterproof

Normal sunscreen has no waterproof function so manufacturers are not allowed to write on their products this feature. However, they can use the word "water-resistant" to promote exaggerated products.

Check your labels carefully. If you use water-resistant sunscreen, you may have to reapply them after about 40 minutes.

Don't forget to protect your lips

The lips are in the middle of the face and they are exposed to the sun just like the rest of your body. So they also need to be protected.

According to a survey, up to 70% of seafarers always let their lips "naked", while this is an easy area to form malignant tumors. So remember to use lip balm and sunscreen to protect your lips.

The safety of sprays

Spray sunscreen is relatively new and convenient to use. However, many people are concerned about safety when using it. Therefore you should thoroughly understand the utility as well as contraindications on the packaging for the right choice.
