Sunscreen must also be applied properly when the new skin is not darkened

Depending on the beauty aesthetic requirements, you should choose a different suitable type. If you need make-up, you should choose a skin-colored cream, an organic cream. If you have to work in the sun for a long time, you should choose cream with inorganic ingredients to work long. For sensitive skin, you should choose a sunscreen with zinc oxide or titanium components, and acne skin, choose a spray product.

1. Only apply cream when going out

The common mistake of many people is to just apply sunscreen when going out, or when the weather is hot. But actually UVA rays can penetrate the clouds, window glass that directly affects the skin causing skin redness, increasing the risk of skin cancer. So you need to apply sunscreen daily, regardless of whether it's sunny or rainy, stay indoors or go to the street.

2. The amount of cream applied is not enough

The famous dermatologist Sam Bunting with over 20 years of experience in the industry has shared that most people only apply 1/4 of the standard sunscreen. Applying too little cream also means the effectiveness of the cream decreases, causing the skin to become black, redness caused by the harmful effects of UV rays. And the most standard cream we need will be 2mg / square centimeter.

3. Do not reapply sunscreen

As we know, sunscreen SPF and PA reflect the time to protect skin from the harmful effects of UVA and UVB rays. SPF 30 corresponds to the ability to protect skin from UVB rays for about 5 hours, while PA +++ reflects UVA resistance in about 8-12 hours. So just applying sunscreen once in the morning is not enough to protect the skin, but need to be carefully reassured to remain effective.

You are often advised to apply the cream again every 2-4 hours when working outdoors. However, one study showed that re-applying the cream after 20-30 minutes when going out in the sun was more effective than waiting for 2 hours. It is possible that the second application of the cream is more effective because most people use it without enough cream, so this supplement will supplement the missing cream. You should also apply the cream again after swimming, sweating or wiping yourself.

In case you are active in a lot of sweat or swimming, you should reapply the cream after about 2-3 hours to compensate for the amount of cream that has drifted.

Please note that sunscreen is the following layer with skin care products. Because if you apply sunscreen to your skin care steps, the nourishing product will not penetrate the inside of the skin, thus losing the improvement effect.
