Sunscreen is very important. It can reduce the impact of ultraviolet rays on the human body, reduce skin stains, relaxation, photoaging, etc., but there are still many people who do not know the importance of sunscreen, and there are some misunderstandings. Today, I will show you the importance and misunderstandings of sunscreen.

The Importance of Sun Protection

Ultraviolet rays can pass through the atmosphere directly on the skin, which will damage the epidermal cells of the skin, accelerate the synthesis of melanin, and make the skin dry and dull. It will also damage the elastic fibers in the dermis and cause the skin to be loose and damaged. Intense ultraviolet radiation can also burn the skin, causing inflammation of the skin. These phenomena will accelerate the aging of the skin, which we call photoaging. In addition, long-term strong ultraviolet radiation can easily lead to skin cancer. So sun protection is very important.

Misunderstanding of sunscreen

Myth 1: Only the summer ultraviolet strong

The natural source of ultraviolet rays is mainly sunlight, but ultraviolet rays do not have temperature, so ultraviolet rays still exist in autumn and winter. Especially in snowy areas, the ultraviolet rays reflected by snow will double. Among them, the shortwave UVA has the strongest penetrating power, which can reach the dermis to tan the skin, which is the most harmful to the skin, and can also cause skin aging and relaxation, long wrinkles, melanin precipitation and even skin cancer.

Myth 2: The skin is not easy to tan, so the sun is fine.

Ultraviolet rays are part of the sun's rays and have irreversible effects on the skin. Redness, blackening or scaling of the skin is normal, but the damage to the cells is irreparable. If protective measures are not taken for a long time, the damage of ultraviolet rays to the skin will accumulate, the skin will be relaxed and aging and stains will be very obvious, and it will be more prone to sunburn. Apply sunscreen to reduce the effects of UV rays on the skin.

Myth 3: Do not go out without sunscreen, only go out to sunscreen

The energy of UVA in ultraviolet rays is stronger and can shine through glass windows on the skin of indoor personnel. Therefore, as long as the sun shines through the glass on the skin for more than 10 minutes, it will also cause damage to the skin.

In addition, ultraviolet rays can also cause damage to the skin through objects that reflect light. Therefore, attention should be paid to all-round sun protection, and curtains should be drawn indoors to block the sun.

Myth 4: Apply sunscreen once can last all day

Sunscreen products achieve the effect of sunscreen by reflecting, refracting and decomposing ultraviolet rays. They also consume themselves while resisting the ground and external lines. Therefore, the sunscreen effect can only be maintained for 3 or 4 hours. Moreover, due to the dilution of sweat, friction and other reasons, its sunscreen effect will gradually weaken, so it is best to reapply once every three or four hours, and once every one or two hours.
