Ask a Dermatologist: Dr. Shereene Idriss on All Things SPF

Physical blockers tend to protect against a broader UV range whereas traditional chemicals are not as extensively protective.

If there is one product you should be using in your skincare routine every single day, it’s sunscreen. (Don’t just take it from me, ask any dermatologist.) Despite the product’s importance and effectiveness, there’s still a lot of misinformation out there. Take a scroll through Instagram or Tiktok and you’re bound to find a post that doesn’t get the facts right. So in order to set the record straight, I reached out to Dr. Shereene Idriss aka the #PillowtalkDerm. She’s here to clear up any confusion you might have about reapplication, UV rays, and why you definitely don’t need a base tan.
