Who is the originator of sun protection? Demystifying the history of sunscreen skin care products

When summer arrives, the ultraviolet rays become stronger and stronger, and the main theme of the beauty circle sings to the sun.

But do you know that in the years when there are no Sunscreen skin care products, sunscreen is the top priority for the nobility.

"Sunscreen" is the originator of the mountain, mask

During the Elizabethan period, a mask that was more red than the Hermes bag was all the rage!

The originator of the "sunscreen" supplies came out like this!

The whiter the skin, the more expensive it is!

At that time, women were more aggressive than "white". In order to block the sun, they wore sunscreen masks made of black velvet. In addition to a bit ugly, this mask also makes the women who love to chat gossip shut their mouths!

Look closely, there is a thread running through the bead at the mouth of the mask. If you want the mask to not fall off, you should use the bead to fix it when you wear the mask. It really deprives the woman of the "right to speak." what!

It’s also interesting, because women’s mouths can’t talk, and women with sunscreen masks make men feel full of mysterious charm...

The first batch of sunscreen products can only relieve sunburn and redness

Time has passed, although women have "taken" sunscreen masks, but the sun's damage to women's skin has been plaguing them, followed by the advent of the corresponding products, but the first batch of products for the sun is mainly In order to alleviate the redness caused by sunburn, and let the skin reduce sun damage after exposure to sunlight. It has not fundamentally isolated ultraviolet rays, and the symptoms are not cured.

In 1928, Dorothy Gray produced the first chemical-containing sunscreen product.

In 1942, during the Second World War, American soldiers suffered from sun exposure during the Pacific Ocean. They used a red vaseline to prevent sunburn, which was difficult to clean because of the texture of Vaseline. The sunscreen effect is significant but not widely used.

After the war, pharmacist Ben Jamin Green developed the physical sunscreen containing red petrolatum for the Coppertone brand, making it the first widely used sunscreen.

SPF was born!

At this time, the American skin care brand Clinique proposed the concept of Sun Protection Factor, which is the familiar SPF value, which is used to calculate how long the sunscreen product can keep the skin from being sunburned. High means that the sun protection ability is stronger. From this moment on, the struggle with the sun began to shift from passive to active, and this milestone concept has been used until now...

The ultraviolet rays in the sun are divided into two types according to the wavelength: UVA and UVB. The penetration of UVA is stronger. It is white. The more you get older, the more you have to blame UVA. UVB directly affects the epidermis. Sunburn and sunburn are UVB. !

So, what do the values ​​that do not understand and the "+" on the sunscreen products represent? First, PA represents the product's protection against UVA, and SPF represents the UVB's protection. The combination of the two is the ability of sunscreen to resist the sun.
