Beauty tips: How sunscreen penetrates the skin

Although there have been many advice from dermatologists about how we need to use sunscreen every day. But many girls are still vague about the protection of this product until now. So how does sunscreen actually protect the skin, why do we need to use this product every day, the image from her below is a concrete demonstration.

The girl on the photo used sunscreen, her image was recorded by both cameras and the UV lens. In normal cameras, you can see that her image is completely normal. Sunscreen quickly absorbed into the skin, nothing special.

So, through UV lens, it can be seen that sunscreen has turned black. Sunscreen now acts like a protective film, limiting bare skin to the negative effects of UVA rays.

In fact, the use of UV lenses to show the optimal skin protection of sunscreen is no stranger. This is a testament to the sun protection ability of sunscreen. When scanning through the machine, you can see that sunscreen has formed a black film covering the outside, making UV rays unable to penetrate the skin - this is the same as when we wear sunglasses or wear many layers.

However, the shirt or glasses only help to avoid the sun but can not prevent UV rays from penetrating (because when compared to the machine, the shirt remains white), then the sunscreen is the perfect membrane preventing all harmful rays This affects our skin.

UV lenses are the specific evidence that reflects the sun protection ability of sunscreen. The cream will form a black film covering the skin

The eye, nose or lips areas are often overlooked areas when applying sunscreen

Sunscreen will be like a protective film, preventing negative effects from UV rays affecting our bare skin.

Besides, when you apply the thicker layer of cream, when you look through the machine, the dark part will be darker. If thinning, not applying enough dosage, there will be more gaps, the cream will only turn pale gray. So, in addition to applying sunscreen, don't forget to apply a 2mg / cm square dose so that the cream has a full skin protection.
