Sunscreen suitable for students How to apply sunscreen

Some students who are conscious of skin care have already noticed that sun protection is the most important step in skin care. So for students, what are some good and inexpensive sunscreens? Let’s take a look together.

Sunscreen for students

Sunscreen is an essential item to fight against the sun. Facial sunscreens suitable for students include: Shiseido Pink Gold Sunscreen for Sensitive Skin, Shiseido Aqua Sunscreen, Innisfree Sunscreen, Biore Sunscreen, and OLAY Sunscreen. Suitable body sunscreens for students include: Maxam Double Protection Sunscreen Lotion and Water Baby Powder Bottle. These sunscreen creams can help the skin block ultraviolet rays and prevent tanning, sun spots, enlarged pores, oily skin and other phenomena. In addition to understanding well-known sunscreen brands, you should also pay attention to how to use sunscreen so that your skin care effects can be twice as effective with half the effort.

How to apply sunscreen

Before applying sunscreen, basic skin care is essential, because the ingredients in sunscreen will absorb a lot of moisture from the skin, especially in summer when moisture evaporates faster. Therefore, after cleansing the skin, first use an appropriate amount of toner, moisturizing lotion or cream, then apply sunscreen, and finally you can use foundation to cover blemishes. Sunscreen is generally applied thirty minutes before going out to maximize its effectiveness. Note that sunscreen needs to be reapplied. It cannot provide sun protection all day long, especially when sweating or when ultraviolet rays are strong, the sunscreen will easily fall off. Generally, the time for outdoor re-coating is about 90 minutes. If you are working near a window indoors, you can re-coat it every 120 minutes.

Benefits of Sunscreen

The benefits of sunscreen are not only to prevent tanning, but also to prevent enlarged pores, wrinkles, sun spots, sunburn, and skin sensitivity caused by sunburn. In short, sun protection is to prevent photoaging. In addition to ultraviolet rays, sunlight also contains a large amount of heat. If you are exposed to too much thermal radiation, it will cause "thermal aging". According to the authoritative magazine Personal Care Magazine, direct exposure to sunlight for 15 to 20 minutes in summer can raise the temperature of the skin to over 40°C. Similar to the effects of ultraviolet rays, this heat can induce matrix metalloproteinases to degrade the extracellular matrix of the dermis, change the protein structure of the dermis, induce angiogenesis and inflammatory cell infiltration in the skin, and cause premature aging of the skin.

Principles of sun protection

Sunscreen is not the first choice of sun protection for both children and adults. We must follow the principle of "one hiding, two covering, three sun protection":

First, avoid the sun : Avoid exposure to the sun between 9 a.m. and 5 p.m., when UV rays are most intense.

The second is shelter : try to find a cool place when outdoors, and use sun-protective clothing, sun hats, umbrellas and other items to block ultraviolet rays.

Finally, there is sunscreen : sunscreen has complex ingredients and often causes adverse reactions, especially in very sensitive infants and young children. And sunscreen cannot block 100% of ultraviolet rays, so it can only be used as a supplementary means of sun protection.
