Why must use sunscreen?
Before 8 a.m., sunlight contains a lot of vitamin D, which is beneficial for the skin and bones. But after 8 a.m., sunlight is considered the number one “enemy” of the skin. Because at this time, the intensity of UV rays is stronger and will have a negative impact on skin health and aesthetics.
Therefore, using sunscreen is extremely important. Sunscreen has the following roles:
Prevents skin darkening, melasma, freckles
Our skin can become dark from the first 5 minutes of being out in the sun. In case you work or move under the sun for many hours, your skin will definitely become dark, black, and sunburned.
Especially the period from 10 – 14 hours (UV rays are highest). Over time, the skin will become hyperpigmented, with freckles and ugly melasma appearing, which will be difficult to improve.
Prevent skin aging
The ingredients inside sunscreen are considered “barriers” that prevent the effects of UV rays, prevent the aging process, and help skin become more youthful and vibrant. Therefore, using sunscreen regularly is the secret to helping you prevent signs of aging.
Enhance skin health
Sunlight has ultraviolet rays that cause rough, dark skin, and even skin cancer. At this time, using sunscreen will help protect the skin from the effects of UV rays. At the same time, it helps prevent acne and limits the appearance of small veins on the skin.
Warning: Skin ages quickly and becomes patchy when using sunscreen incorrectly
Sunscreen is considered a “savior” to protect the skin. However, using sunscreen incorrectly is both ineffective in protecting the skin and harmful to the skin. Below are some common mistakes that cause skin to become patchy and age prematurely:
Do not clean your skin after using sunscreen
Many people think that if they don’t wear makeup and only use sunscreen, they don’t need to remove makeup. This concept is very wrong, causing pores to become clogged, skin to become easily irritated, acne-prone, sensitive, and accelerate the skin aging process.
If it’s not sunny, you don’t need to apply sunscreen
This is also a common mistake among women when they only apply sunscreen when going out in the sun. But according to dermatologists, 80% of UV rays still appear even when it’s not sunny.
On shady or overcast days, UV rays still exist in natural outdoor light. Therefore, to prevent aging, don’t forget to apply sunscreen every day in all circumstances.
Not applying enough sunscreen
Using too little sunscreen will make the skin unable to protect itself from the effects of UV rays. Therefore, the skin remains dark, melasma appears, and accelerates the aging process.
Don’t pay attention to SPF and PA index
SPF and PA are indicators that measure the ability to protect against UVA and UVB rays over time. Choosing a sunscreen with an SPF index that is too low or without a PA index will not prevent the harmful effects of ultraviolet rays. Therefore, you should choose products with a minimum SPF index of 30 and PA+.
Choosing sunscreen that is not suitable for your skin
Oily skin, normal skin, and dry skin will have different characteristics. So, choose sunscreen based on your skin characteristics. For example, if you have oily skin, you should use an oil-free, fast-absorbing sunscreen. Dry skin should prioritize choosing sunscreen rich in moisturizing ingredients.
