Your Guide to Finding the Best Sunscreen, According to a Dermatologist

How can you find the right formula for you?

In short, said Dr. Wang, “The best sunscreen is the one you will use.”

But if you want more insight, he said you can never go wrong with a fragrance-free sunscreen. It’s an especially great option for sensitive and acne-prone skin types, as the doctor noted “heavy creams and highly fragranced lotions can cause skin irritation.”

Moreover, a sheer formula not only feels nice but it’s more user-friendly and works well for all skin tones since it doesn’t leave behind the dreaded white cast. And as tempting as spray sunscreens can feel, Dr. Wang explained that they require painstaking thoroughness. 

“Spray sunscreens can be as effective as sunscreen lotion, but it requires the user to rub the sunscreen evenly into the skin after it’s sprayed on,” the doctor explained. “It’s often easier to miss a spot with spray sunscreens since they go on clear.”

What is the recommended SPF number?

When it comes to daily use and for people who will be indoors most of the day, Dr. Wang suggests a minimum of SPF 42. “If someone is planning to be outside for extended periods of time,” he continued, “SPF 55+ is recommended.”

His product pick? Shiseido’s Urban Environment Vita-Clear SPF 42. He said it gives the skin “powerful protection” and also brightens it since it’s infused with vitamin C.

“It blocks UVA, UVB rays and pollution, while visibly boosting brightness and smoothness,” he shared. “The weightless, skincare-like texture also has an invisible finish that goes on clear.”

How often do you need to re-apply sunscreen?

If you’ll be soaking up some sun, then Dr. Wang said it’s best to re-apply every two to three hours. However, “if there is intense sweating or water activity,” he added, “reapplication every 60 to 90 minutes will give the most effect.” However, for those days when you’re mostly indoors, you don’t need to re-apply SPF as often. Four to six hours will do the trick.
