What does SPF 50 and SPF 30 mean? Which one is more suitable for you?

We know that sunscreen products all have their own sun protection index. The more common ones are spf30 and spf50. Let’s take a look at the meaning of sun protection index 50 and 30 and what the difference is between the two!

The significance of SPF 50 and 30

The SPF is a test index that measures the ability of sunscreen to defend against ultraviolet UVB in sunlight. It indicates the sun protection effectiveness of sunscreen products. Assuming that your skin starts to turn red after 10 minutes of sun exposure without applying sunscreen, a product with an SPF of 50 can protect your skin for 500 minutes, while a product with an SPF of 30 can protect your skin for 300 minutes.

The difference between spf30 and spf50

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.

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.
