How to choose the right sunscreen?

Question

Hello doctor,

I am a 23-year-old civil engineer, female, who spends a lot of time on construction sites. I am trying to nail down the best way to use sunscreen in my skincare routine. What should I look for in a good sunscreen, like SPF levels and ingredients?

Any tips on how to apply it properly and make it part of my daily routine would be super helpful. I want to make sure my skin stays healthy and protected despite being out in the sun a lot.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

For daily use, especially given your exposure to the sun, a sunscreen with an SPF (sun protection factor) of at least 30 is recommended. SPF 30 blocks about 97 percent of UVB (ultraviolet B) rays, while SPF 50 blocks about 98 percent.

If you have fair skin or are in the sun for extended periods, you might consider a higher SPF.

Sunscreen should be labeled as “broad spectrum’. This means it protects against both UVA (ultraviolet A) and UVB rays.

Since you are likely to sweat while working on construction sites, choose a water-resistant sunscreen.

Physical Sunscreens: Contain active mineral ingredients like zinc oxide or titanium dioxide. These sit on the skin’s surface and reflect UV rays. They are less likely to irritate, especially if you have sensitive skin.
Chemical Sunscreens: Absorb UV rays and convert them into heat, which is then released from the skin.

I would suggest you do the following:

Look for sunscreens labeled as non-comedogenic. Apply sunscreen as the last step in your skincare routine.
Use about a teaspoon of sunscreen for your face.
Apply 15 to 30 minutes before going outside.
Reapply every two hours. Set an alarm or reminder on your phone to reapply sunscreen throughout the day. Keep a small bottle of sunscreen in your bag.
Cover all exposed areas like ears, neck, and back of the hands.
Lip balm with SPF is also important.
Make it a habit to apply sunscreen every day, regardless of the weather.
Wear a wide-brimmed hat, sunglasses, and covered clothing.
Stay hydrated.

I hope I have answered your question.
