3 types of sunscreen should consider carefully before withdrawing money to buy

The 3 sunscreens below do not really bring positive effects to the skin, so you should consider carefully before withdrawing money.

Strong sunlight not only darkens the skin, sunburns but also accelerates the aging process, destroys collagen and increases the risk of skin cancer. Regular use of sunscreen is a simple but will help you minimize the bad effects. However, not all sunscreens like the 3 sunscreens below do not really bring positive effects to the skin.

1. Sunscreen Doesn't Have "Broad Spectrum"

Broad spectrum sunscreens come with broad spectrum packaging, which means they offer both UVB and UVA protection.

UVB rays, with wavelengths between 290nm and 320nm, can cause other visible changes to the skin's surface such as sunburn and darkening. UVA rays have a wavelength from 320nm to 400nm, a larger range than UVB, accounting for about 95% of UV rays reaching the skin. UVA rays accelerate the aging process. Both UVA and UVB cause negative effects on the skin. Therefore, you need to choose broad-spectrum sunscreens to protect your skin from damage from these two types of rays.

2. Low SPF sunscreen

SPF is calculated according to the number of hours and percentage when using sunscreen, this is also the common norm of sunscreens in the world. You should use sunscreen with a minimum SPF of 30 or higher. In case, you participate in outdoor activities or are exposed to the sun for a long time, sweat a lot, you should choose a sunscreen with an SPF of 50 or higher.

Conversely, sunscreens with too low SPF will not be able to provide comprehensive skin protection.

3. Alcohol-based sunscreens cause eye irritation

Alcohol in sunscreen can sting the eyes, cause discomfort, can not be used for the skin near the eyes. If you have sensitive, easily irritated skin or are afraid that alcohol will sting your eyes when sweating or raining, you should avoid choosing sunscreens that contain alcohol.

There are many quality alcohol-free sunscreen lines available, which help protect the skin without causing eye irritation or discomfort.

Also, when using sunscreen, don't forget to apply it at least 15 minutes before going outside. This is the time for the cream to stabilize, create a good sunscreen film, if you sweat a lot, you need to reapply the cream every 2 hours to ensure effectiveness.

In the evening, don't forget to remove your makeup to remove any remaining sunscreen residue under your skin. Otherwise, sunscreen ingredients will accumulate deep in the pores, causing acne.
