What is the difference between spf30 and spf50 sunscreen?

Sunscreen is a product that everyone has in the summer, but the values ​​on sunscreen are different. So which one is better, spf30 or spf50? What is the difference between spf30 and spf50 sunscreen?

Which is better, SPF30 or SPF50 sunscreen?

The SPF value of sunscreen should be determined according to the usage environment. If you go out normally, SPF30 is enough. If you are outside for a long time, you should use SPF50. However, please note that the higher the SPF value, the greater the damage to the skin.

As for traveling or outdoor sports, for example, the military training season is approaching, there will be no problem if you choose SPF50, and it is best to be waterproof and sweat-proof, after all, you don’t need to use it every day. But it doesn't matter if you only have SPF30. In fact, no matter what the index is, as long as you stay outdoors, you should reapply it every two hours. From this perspective, there is basically no difference between SPF30 and SPF50. As for the higher SPF80 and SPF100, they are simply for professional skiers. Why would an ordinary person bother with that index?

Instead of staring at the index, it is better to take a good look at how many + signs are behind PA. This is the key indicator for protecting against UVA. UVA is the ultraviolet light we should prevent the most. It can cause skin inflammation, cause melanin formation, and damage collagen and skin cells, causing skin aging.

So after seeing this, we should understand that our country’s standards do make sense. The most suitable sunscreen for daily use is spf30 PA+++.

What is the difference between spf30 and spf50 sunscreen

1. Different texture

Among products of the same brand and the same formula, SPF30 products are lighter and more breathable than SPF50 products. This is because the higher the SPF value, the more sunscreen is added and the worse the permeability, which will hinder the normal secretion and breathing of the skin. If you have acne-prone or sensitive skin, it is recommended to use a sunscreen with a lower SPF.

2. Different security

SPF30 products are safer than SPF50 products because the higher the SPF value, the more chemical sunscreen is added, and this type of sunscreen is corrosive. The more added, the more corrosive it is. Too much sunscreen can easily penetrate into the skin and cause allergies and other problems.

3. Different sunscreen durability

SPF30 products provide longer-lasting sun protection than SPF50 products because SPF30 products can extend the protection time by 30 times, while SPF50 products can extend the protection time by 50 times. Of course, the durability of a sunscreen is not only determined by SPF, the PA value is also very important. However, generally speaking, sunscreens with a higher SPF index also have a high PA value.

4. Suitable for different places

SPF30 products have a slightly weaker sun protection ability, but are safer, and are suitable for use when you often need to run around outside or travel; SPF50 products have a stronger sun protection ability, but are slightly less safe, and are suitable for use at beaches or when traveling to tropical areas.

Okay, friends, you know that the quality of sunscreen SPF30 and SPF50 depends on the environment.
