You definitely need to know how to apply sunscreen when going to sea. However, dermatologists recommend that you use sunscreen when outside for longer than 20 minutes, even in winter. You should apply sunscreen even when it is shady or gloomy. UV rays (UV rays) can damage the skin within 15 minutes! These lesions can lead to skin cancer
PART 1. CHOOSE SUNSCREEN
1. Learn the SPF
"SPF" is the "sun protection" index of sunscreen or the number of hours the skin is protected from UVB rays. SPF reflects sunscreen time when applied and does not apply cream.
For example, using SPF 30 sunscreen you can stay outdoors for 30 times longer without applying sunscreen without sunburn. Normally, you will be caught only after 5 minutes of sun exposure, the SPF 30 will allow you to stay outside for 150 minutes (30x5) without sunburn. The condition of the skin, activity and intensity of sunlight may affect the effect of sunscreen, so you must consider how to use it to suit the skin.
The SPF may not be accurate because of the fact that the level of protection is not increased proportionately. SPF 60 does not protect against sunlight twice that of SPF 30. SPF 15 blocks 94% UVB rays, SPF 30 is 97% and SPF 45 is 98%. No sun block can block 100% of UVB rays.
The US Dermatologist recommends using SPF 30 or higher. The difference with high index sunscreen is often not obvious, so it is not necessary to spend extra money.
>>>Why we should use cream with SPF of 30 or more?
2. Choose "broad spectrum sunscreen"
SPF only reflects UVB protection against sunburn. But the sun also contains UVA rays that cause skin damage such as aging, wrinkles, bruises. Both increase the risk of skin cancer. A broad spectrum sunscreen will protect your skin from UVA and UVB rays.
Some sunblock does not write "broad spectrum" on the package. But it is always stated that there are anti-UVA and UVB rays.
Broad spectrum sunscreen usually contains "inorganic" components such as titanium dioxide or zinc oxide, "organic" components such as avobenzone, cinoxate, oxybenzone or octyl methoxycinnamate.
3. Find a water-resistant sunscreen

Just for fun. Perhaps the landlord did not apply waterproof sunscreen to it |
Ok, let's come back!
Because the body evaporates from sweat, you should use water-resistant sunscreen. Especially when participating in active activities such as running, climbing or running under water.
No sunblock has the ability to "waterproof" or "waterproof sweat." In the US, sunscreen is not self-marketing "waterproof."
Even if you use water-resistant sunscreen, you should apply it after 40-80 minutes or follow the instructions on the package.
4. Choose the type you like
Many people like ice cream spray, others choose cream or gel. Whatever your choice, be sure to apply a thick, creamy coating. Applying creams is as important as the SPF and other factors: If you do not apply the cream properly, sunscreen does not work.
You should use a spray for hairy areas and cream for dry skin. Sunscreen contains alcohol or gel suitable for oily skin.
You can buy a waxy sunscreen suitable for the area near the eyes.
Water-resistant sunscreen is slightly sticky, should not be used before makeup. Use sunscreen suitable for skin type, with SPF (15 or higher), do not clog pores or cause acne.
5. Try the skin around the wrist
If you have an allergy or skin problem, buy another one. Repeat the process until you find the right sunscreen, or talk to your doctor about the brand to use if your skin is sensitive or allergic to it.
Pruritus, redness, burns or acne are signs of allergy. Titanium dioxide and zinc oxide are less likely to cause skin allergies.
PART 2. APPLY SUNSCREEN
1. Check the expiry date
FDA requires sunscreen to maintain protection within 3 years of manufacture. However, you should still check the expiry date. If the product has expired, remove the old one and buy a new one.
If the product is not in use, use a marker or label to write the date of purchase on the bottle. You will know when you buy the product.
Substantial changes in the product such as color changes, water splashes, many other attributes are signs of the cream's expiration.
2. Apply the cream before going out
Take time to composition of sunscreen to soak the skin and completely protect the skin. Apply sunscreen before going out.
You should apply the cream 30 minutes before going out. Apply between 45-60 minutes before going outside.
3. Use enough
One of the biggest mistakes when applying sunscreen is not enough. Adults need 1 ounce (about 30g) - full of palm, or a cup full of sunscreen to cover the body.
To apply cream or gel cream, squeeze the cream out of the palm. Apply to skin exposed to the sun and massage until the cream penetrates the skin.
To use the spray, you hold the bottle upright and spray on the skin exposed to sunlight. Spray all over the skin. Do not stand in front of the wind to avoid spray-on lotion before exposure to the skin. Do not inhale the spray. Exercise caution when spraying on face, especially when there are young children around.
4. Apply sunscreen throughout the body
Memorize parts such as ears, neck, nose, hands, or even hair. Any area exposed to the sun should be covered with sunscreen.
It is difficult to cover the hard areas with the back. You can ask the person who helped put the cream on the skin.
Slim clothing can not protect the skin from the sun. For example, if you're wearing a white T-shirt, the SPF is just 7. Make sure you're wearing UV-protective clothing, or apply sunscreen.
5. Reapply every 15-30 minutes
Research has shown that you should apply cream for 15-30 minutes after exposure to sunlight, it will be effective after 2 hours.
After applying the cream for the first time, the next time you can apply the cream every 2 hours, or follow the instructions on the package.
PART 3. SAFETY UNDER THE SUN
1. Stand in the shade
Even when applied sunscreen, the skin is still exposed to sunlight in strong intensity. Stand in the shade or cover to protect your skin from the sun.
Avoid "peak hours". The sun rises from 10 am to 2 pm. If possible, you should avoid going out at this time. Find shady if you have to go out.
2. Do not let young children out in the sun
Sunshine, especially the period of the sun on the "peak" from 10-14 hours extremely toxic to young children. Buy sunscreen specifically for infants and babies. Consult your pediatrician to decide on a safe baby's skin cream.
Children under 6 months of age should not apply sunscreen or direct sun exposure. Young children skin are not finished so easily absorbed chemicals in the sunscreen. If it is imperative to take care of your baby, keep the baby in the shade.
For children over 6 months, you can apply a broad spectrum sunscreen with an SPF of 30. Exercise caution when applying cream near the eye area.
Dress your child's sunblock, hat, long sleeved shirt and long pants.
Have your child wear UV-proof sunglasses.
Advice
Buy face cream exclusively. If it is oily and acne prone, look for "oil free" or "no pores" cream, with sensitive skin you can buy special formula sunscreen.
Even if you apply sunscreen, you should not be exposed to the sun.
Reapply if the person is wet, or after every 2 hours, or as directed on the package. Sunscreen is not a "one time" product
Warning
There is no "safe" sunbathing. UV rays from sunbeds or natural sunlight are at risk for skin cancer. Honey-colored skin can make you look seductive but will be harmful to your health
