That doesn't mean you have to buy sunscreen every year. Over time, the ingredients break down and become less effective. If you've ever used old sunscreen and squirted a separated mixture into your hand, you know firsthand that sunscreen expires. You can avoid this by opting for a sunscreen formulated for sensitive skin. A study published on JAMA Network discovered that 6 of the 13 ingredients in chemical sunscreen that the FDA is currently considering were absorbed and detectable in the bloodstream up to three weeks after one application.Īdditionally, some sunscreens can irritate sensitive skin or cause an allergic reaction because of the ingredients like fragrances. While the FDA hasn't found significant evidence that chemical sunscreens are harmful, more research is needed to conclude. There has been an ongoing debate on the health risks of using chemicals in sunscreen. The conversation around sunscreen safety mainly concerns oxybenzone and other chemical ingredients in some sunscreens. Establishing a base tan with a session at the tanning salon is still doing damage to your skin. Even if you don't have sunburn, unprotected sun exposure increases your chance of developing skin cancer. Having a base tan doesn't protect you from the sun and is a sign of skin damage. The skin protects itself from further damage from UV rays by darkening. You'll still get approximately 2% to 3% of UVB rays, enough for your body to create vitamin D. No sunscreen blocks 100% of sun rays, even if the packaging says 100 SPF. Essentially, we need sunlight to make the necessary amount of vitamin D that allows our body to absorb calcium and phosphorus. Vitamin D is the essential vitamin made when the protein in our skin reacts to UVB rays from the sun. You'll get a vitamin deficiency if you wear sunscreen ![]() Even if it's cloudy, it's best to put on sunscreen. While clouds can reduce the sun rays getting to your skin, they are not substantial enough to block them completely. But let me ask you, what is a cloud? If you guessed water vapor suspended in the air, then you are correct. Some people assume that no sunscreen is necessary because the sun is behind the clouds. You only need to wear sunscreen when it's sunny It's important to note that people with darker skin tend to have lower survival rates because they are often underdiagnosed, not merely because of the color of their skin. A study published in the Journal of American Academy of Dermatology found that people with darker skin tend to have lower survival rates for skin cancer, reinforcing the need for every person to wear sunscreen. However, people with darker skin can still develop wrinkles, hyperpigmentation, sunburns and skin cancer. Melanin does offer some natural protection from the sun by diffusing UV rays. If you're wondering how the heck you're going to apply sunscreen after you've done your makeup, you can either blot your sunscreen on top of your makeup with a beauty sponge or buy a powder sunscreen like the Colorscience Brush-On Sunscreen. ![]() ![]() Makeup with SPF is a nice addition, not a replacement for sunscreen. There's too much variation in how people apply makeup to say it's enough. In practice, you're probably not getting all the SPF on the bottle if you only apply a thin layer of the product. ![]() When testing, skincare companies test with thick layers of the product to determine the SPF. But it's not enough to provide adequate protection from the sun. Using moisturizer or makeup with SPF included is a great way to add more sun protection. Makeup with sunscreen is all you need to protect your face The American Academy of Dermatology recommends using a broad-spectrum, SPF 30 or higher, with reapplication every 2 hours. I caution that these numbers are determined in a lab, with perfect application that doesn't account for things like sweat, skin oils or accidentally rubbing off the product. If you applied SPF 30, it would take 30 times longer - 300 minutes total. This metric is based on how long it takes your skin to burn in the sun without protection. What does the number on your bottle of sunscreen mean? SPF stands for sun protection factor and measures how long a sunscreen protects against UVA and UVB rays. ![]()
