Everything you need to know about sunscreen with mattresses

ONEAsk any dermatologist what is the most important skin care product and without fail to answer “sunscreen”. But while you can apply the skin-recommended SPF 30 to reg (okay!), You may not get as much protection as you think. The skin suggests using a teaspoon of sunscreen for the face and neck and a glass that is worth it for the body, but in reality, most people use much less than that. Therefore, if you do not use a teaspoon of foundation with SPF 30 (why who is it?), You are not really getting this level of sun protection – it is probably closer to SPF 10.

But do not worry: You do not need to consume an unrealistic amount of a product to ensure that you are properly protected. Derms say you can layer Instead, type in your SPF.

“The benefits of applying SPF – for example, a sunscreen with SPF makeup – are that you probably do not use enough sunscreen,” says Elizabeth Kream, MD, a dermatologist and third-year student at the University of Illinois. in Chicago. “Adding a second coat of the same product or a second product such as a solid powder with SPF will bring you closer to the recommended dose and closer to that actual SPF.”

Layered sunscreens can also allow you to get different types of protection. For example, sunscreens that use mineral inhibitors, such as titanium dioxide and zinc oxide, naturally protect your skin from UV rays by deflecting the sun’s rays away from your skin. Chemical blockers, such as homosalate and octinoxate, work by absorbing UV rays before your skin has a chance to absorb them. By placing both layers, you will have both types of protection.

The do’s and don’ts of sunscreen

1. Allow the sunscreen to dry between coats

“If you apply a mineral sunscreen to wet skin, it does not go away,” says Shirley Chi, MD, a certified dermatologist in Southern California. “And while chemical sunscreen can be mixed into wet skin, it will not work either.” Chemical sunscreens work by interacting with the top layer of your skin to absorb UV rays, so that these rays can not enter the skin and cause damage. If you are into these types of formulas for wet skin, they will not be able to penetrate so easily, which means that they will not work to their full potential.

2. Start with a basic layer of simple sunscreen

When applying SPF, Dr. Kream says always start with a simple sunscreen, which means a product that has the sole purpose of providing sun protection (hence, not based on SPF). For optimal coverage, follow the above tips of Dr. Chi and make sure that your other skin care products are completely dry before using your sunscreen. Aim to spread a teaspoon of the product on your face and neck. Another way to measure is to make a peace sign with your hand and draw a line of sunscreen on both fingers.

3. Do not use avobenzone

When you apply a chemical to physics, Dr. Kream tells you to avoid chemical sunscreens that use abobenzone. These are best used on their own.

“Avobenzone, in particular, does not play well with others, as it can be easily turned off and requires the addition of photo stabilizers,” he says. “Fortunately, there are many other options that do not have abobenzone as the active ingredient.”

4. Do not forget to reapply

Applying multiple coats of sunscreen simply increases the amount of SPF you wear. This does not mean that you can extend the time between re-applications.

“Reapply is recommended every two hours or every 80 minutes if you sweat or swim, regardless of the protection index,” says Dr. Kream. “Even if you apply SPF 100, you have to reapply every two hours. This is simply because no matter how well a sunscreen blocks ultraviolet radiation, it wears out after a few hours.
