Spartanburg, South Carolina (WSPA) – When the sun is full, you can get a healthy amount of vitamin D, but if you don’t protect it, it can hurt your skin.

Types of sunscreen

Dr. Amy Lin Frankel, an advanced dermatologist at Sparthamberg, said there are two types of skin protection, physical and chemical.

“The physical blockers are titanium dioxide and zinc oxide, which are basically crushed particles that adhere to the skin and act like a film that protects you from the sun as a physical barrier. Prevents it from actually getting into your skin, “Dr. Frankel explained.

“Chemical blockers are compounds that are crushed into nanoparticles. They go to your skin and when the sun’s rays hit them, they convert that energy into heat, so it dissipates so that it is not absorbed by your skin. Will be done, “she explained.

Dr. Frankel said it was the best bet, as physical blockers block all the harmful rays of the sun.


Dr. Frankel said higher SPF is best, but reapplying is important.

“If you want to install it only once, please get 100 pieces. [SPF]”Dr. Frankel said. “If you do it as you are supposed to do and you’re going to put it every 40 to 80 minutes, then 30 [SPF] fine. But no one is doing that. With a spray, you really need to use a lot. And that’s where people are wrong. Therefore, spray for about 2 seconds out of 3 seconds. This probably corresponds to an SPF of 10 or 12. “

Remember to rub the sunscreen to form a protective layer. This also applies to spray sunscreens.

When to wear

On bright, sunny summer days, it’s clear that you should apply sunscreen before you leave the house.

When clouds are around, some of the sun’s energy is reflected by the clouds into space, some is absorbed by the clouds, and the rest travels to the ground and reaches the skin directly. It’s when you face the risk of sunburn and skin cancer.

According to Dr. Frankel, children’s skin is particularly vulnerable to future harm.

“In fact, we see an increase in skin cancer diagnosed in young people in their 20s and 30s, which is all the damage they did when they were children,” she explained. .. “So, as a parent, you have the ability to change their sun habits when they are young. Also, because it is the cause of melanoma, prevent these blistering sunburns early. You can prevent melanoma. ”

Dr. Frankel said SPF clothing, or sun shirts, are a great choice and annual skin tests can help detect potential problems early.
