Common mistakes when using sunscreen

Only the SPF number as high as possible

SPF (Sun Protect Factor) means the factors signalling elements cover skin from the Sun. The specified substance possibility SPF sunblock to help delay the possibility of burning the skin when exposed to sun rays. How to choose the proper SPF number only depending on sun exposure and environment resistant to sunlight.

If you think regular lotion with high index is your skin has completely protected from the rays of the Sun is completely wrong. The higher the SPF number only does not mean that the effects may last longer than the lower index. Fact, there kinds of sunscreen with UV resistant to 100%. And the higher the SPF means with the possibility of the chemical in the product, easy lead to the problem of dry skin, irritation and sensitization.

The level of moderate and safe sunblock is SPF 15 SPF to 20. However when it comes to sea or out in the sunny day should use sunscreen having SPF number only from 20 to 30.

The shaded and Sun in the room without using sunscreen

Although sitting in the room or stand under the shady tree but still could not avoid the emission of ultraviolet. Therefore, although sitting in the shade, a little balm sunscreen to protect your skin!

Topical sunscreen and out right

This is the mistake of not many people know. Sunscreen can only fully work if they were smeared before setting off from 15-30 minutes, by the cream takes time to absorb into the skin. Most manufacturers have instructions about this, but most of the sisters back skip this precious advice.

Share a bottle of cream for face and body

Protection products for the body are usually very high in oil, if illuminate the face will be uncomfortable, sticky greasy. Therefore, with the facial skin, you should use the type is reserved for this region; It's not just a dry, light but also help you not have to obliterate a layer too thick, for makeup.

The amount is not enough cream

Depending the type of sunscreen has SPF high or low that obliterate the amount of cream how many is enough and is effective against the Sun. For this type have SPF 15 and over, with an area of a face just about 2, 5 g of cream is enough. The simplest way to determine the amount of cream is used ngòn head full of cream, 1 pointing index finger is enough for the entire face. If lather is not sufficient amount of sunscreen protection results will less, time Sun will short.

Lather once used for all day

Many people have misconceptions, smeared sunscreen will help protect your skin all day. Sunscreen should be reapplied after two hours, after exercise or when participating in water-related activities. Best, check the manufacturer's manual to know how often need reapplied sunscreen.

Given sunscreen

Not a few people said that when they use the Sun products and then their skin was protected. This is completely wrong. The fact that only use sunscreen not enough, you must use the right way, the correct type and besides that should also shield the skin by though, caps or clothing. The period of time from 10 am to 4 pm at the most powerful UV, you should avoid going out in the Sun at this time.

Just based on the SPF number only

You forget that in addition to the UVB of sunlight also contains both UVA rays, both are damaging the skin, leading to the risk of skin cancer. So, buy Sun products based solely on SPF number only is not enough. You should choose the type can protect skin from both types of UV rays. Often the products are resistant to UVA has 3 levels, will be noted as the PA +, +, +, +, +, +, as much of the "+" sign, the higher the effect.

A big sister's mistake when using Sunscreen SPF myths that is incremental in nature, this is a completely wrong thinking. For example, when you use sunscreen having SPF 15 SPF 30 and you will never get the SPF 45. Sunscreen not incremental in nature as such. What if you apply two layers of sunscreen on each other then the effect could be greater than the Sun.

Only apply the cream in the "important"

The face, arms or legs are always thorough care, but those seats and another often forgotten. Remember, the neck, ears, head, neck, chest, and body are all cream applicator should be if an bikini beach.

Ignore the heel, neck, spine, behind the ear

When topical sunscreen should not miss any areas. Many believers often miss the heel, neck, spine and back of ears that do not know that this is not good. The sensitive skin will rapidly aging after exposure to the Sun.

Go swim no need sunscreen

Sink under the cool waters often makes us forget he was the Sun, and hence, also strongly stain human skin faster! Select the type of waterproof sunscreen in this case! Each time after swimming, also need to obliterate add a layer of sunscreen to the room except for the creamy layer from being passed under the water!=
