What is the correct way to protect yourself from the sun?

From the essence of sun protection, what we protect against is ultraviolet rays. Ultraviolet rays that cause damage to human skin are divided into two categories:

►Long-wave ultraviolet rays UVA, codenamed the Big Devil. It has strong penetrating power and can reach the superficial layer of the dermis. (It’s this thing that made you dark and wrinkled! It’s the culprit! The bad guy! Beat him up!)

►Short-wave ultraviolet rays UVB, codenamed the little devil. The penetrating power is weak and can cause sunburn to the epidermis. (This is what makes your skin red and peeling!)

In terms of sun protection, it protects against the following damages:

► Anti-photoaging. Sun protection is the first step in anti-aging! Long-term exposure to sunlight can cause skin aging or accelerate aging.

Aging itself is a law of nature. However, exogenous aging of the skin caused by ultraviolet radiation can be alleviated by sun protection. So don’t think that sunscreen is just for tanning, it also prevents wrinkles.

The picture below shows a veteran driver from the UK. He has been driving for 28 years and his left face has been exposed to sunlight all year round, so the wrinkles on his face are more obvious than on his right face.

►Prevent tanning. We get darker because ultraviolet rays stimulate the basal layer of our skin.

Skin thought: Emma scared the baby to death, oooohhhh this won’t do, I have to protect myself.

Therefore, melanin is its protective color, which causes the formation of dark spots. Do a good job of sun protection, and your whitening journey will not be so difficult, okay~

►Protect against sunburn. Skin sunburn, also known as solar erythema, is an acute phototoxic reaction caused locally after exposure to ultraviolet rays.

The skin is frightened and cries out in grievance, with burning and stinging, and even edema and blisters, which subside within a few days, and then peel off, and secondary pigmentation occurs.

►Prevent photosensitivity and photosensitivity skin diseases. The above-mentioned photoaging, tanning and sunburn are all normal reactions of the skin to ultraviolet radiation, while this one is an abnormal reaction. Under the mediation of photosensitive substances, the skin's tolerance to ultraviolet rays is reduced or its sensitivity is increased, thus causing skin phototoxic reaction or photoallergic reaction.

Ultraviolet rays appear as the sun rises, but we are not people from the polar regions, so there is no polar night phenomenon! Ultraviolet rays are present all year round, so don't associate them with heat sensation. Wear sunscreen on cloudy days and 365 days a year.
