You might ask, can Sunblock Cream prevent skin cancer?The food and drug administration agreed.Wolverine star Hugh jackman has undergone his sixth operation for a recurrence of basal cell carcinoma.The national icon took to social media to urge people to take precautions against skin cancer after his illness.For him.
In the United States, Sunblock Cream is regulated by the FDA as a drug.That's because the U.S. food and drug administration says sunscreens do exactly what drugs do: prevent sunburn, reduce the risk of skin cancer, and prevent early skin aging from the sun.How can science prevent sunburn effectively after all?Let's take a look at what the FDA says, along with advice from Cleveland clinic dermatologist Melissa pierian and Mayo clinic dermatologist Lawrence Gibson.
First, the sun's damage to the skin
There are two types of UVA and UVB radiation in sunlight.UVB rays can burn the skin.Prolonged exposure to sunlight is too harmful to the skin, while exposure to UVA and/or UVB rays increases the risk of skin cancer.
Two, how to choose sunscreen products?
You need a Sunblock Cream with UVB and UVA broad-spectrum or multispectral protection.Broad-spectrum protective ingredients include diphenylketone (hydroxymethoxybenzenone), cinnamic acid (octyl cinnamate and siloxane), sulfoxide, salicylate, titanium dioxide (titanium dioxide), zinc oxide, Parsol 1789 and ecamsule Mexoryl SX.
We need UVB protection above spf15.SPF is a measure of Sunblock Cream's resistance to UVB rays.If you normally get a sunburn within 10 minutes, SPF 15 will multiply by 15, which means you won't get a sunburn for 150 minutes.For most people, spf15 is enough.But people with fair skin, a family history of skin cancer or lupus, or who are more sensitive to sunlight, should consider Sunblock Cream with an SPF of 30 or higher.Remember, the higher the SPF, the less effective it is: contrary to what you might think, spf30 is not twice as effective as spf15.While SPF 15 filters out 93% of UVB rays, SPF 30 filters out 97%, a small increase.
UVA protection, there's no level that tells you how good Sunblock Cream is at blocking UVA rays.Therefore, when it comes to UVA protection, you need to pay attention to its active ingredients.Sunscreen should contain at least one of the following ingredients: icazole, avobenzone, oxybenzone, titanium dioxide, sulfoxide or zinc oxide.
