The difference between 30 times and 50 times sun protection

Sun protection is something girls do almost every day. When choosing the SPF of sunscreen, many people don’t know what value to choose. Let’s take a look at the difference between 30 times and 50 times sun protection.

The difference between 30 times and 50 times sun protection

The difference between SPF 30 and SPF 50 is how long the UV rays are blocked. Theoretically, SPF 50 can block UV rays longer and is more effective than SPF 30, but the maximum factor of most sunscreen products on the market is 30 times, and SPF 50 is relatively rare. In general, SPF 30 is sufficient.

The difference between spf30 and spf50

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 sun protection durability

SPF50 products provide longer-lasting sun protection than SPF30 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 higher 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.
