We all know that the sun is a major health hazard. Too much exposure can lead to skin cancer, premature aging, and other harmful effects. Sunscreen protects us from these risks by blocking out some of the UV light from the sun. But how do you know how much sunscreen you need? It’s not as simple as slathering on a thick layer and hoping for the best. You might be applying too little or too much if you don’t follow this guide!
How Much Sunscreen Do You Need?
It’s not as simple as slathering on a thick layer and hoping for the best. You might be applying too little or too much if you don’t follow this guide!
Sunscreens are a balancing act between too much and not enough. It’s always best to err on the side of caution, but it is possible to use too much if you don’t follow these guidelines. If you’re using an SPF 15 sunscreen with broad-spectrum protection, you’ll need about one full shot glass or two tablespoons for your whole body. If you’re using an SPF 30 sunscreen, about one shot glass or two tablespoons are enough for your face and neck.
The type of sunscreen you use is also essential. SPF only refers to protection from UVB rays, not UVA rays. If your sunscreens provide broad-spectrum coverage, then just one full shot glass or two tablespoons are enough for the body as a whole because it blocks both types of damaging light at once.
What Type of Sunscreen Should You Use?
The FDA recommends using sunscreens with broad-spectrum protection from both UVA (aging) and UVB (burning) rays. Sunscreens that only protect from one or the other are becoming obsolete with time because they offer less protection from the growing number of harmful ultraviolet lights in our environment today.
If you do choose to use sunscreen without broad-spectrum coverage, then make sure it is at least SPF 15 for adequate protection.
How Many Times Do You Need To Apply Sunscreen Throughout The Day?
It’s always best to reapply sunscreen at least every two hours, but it can be anywhere from once per day up to four times. This is because the sun’s rays are constantly damaging your skin, and a constant application of sunscreen will help lessen the chance of a bad sunburn. If you are swimming and in and out of the pool, it’s best to reapply your sunscreen more often.
Having to worry about sunscreen can seem like a bother, but just reducing your chances of skin cancer and damage makes it worth it. Applying sunscreen routinely, picking the right sunscreen, and applying the right amount will make your time in the sun that much safer for you.
