The sun is the number one cause of wrinkles, with dozens of studies documenting the impact. A lot of people may or may not wear sunscreen whether they are spending time inside or out, but it’s one of the most important things you can do for your skin. It’s important to note that no matter what your skin tone or color is, wearing sunscreen year-round will prevent skin damage from UV rays, thus minimizing your risk of skin cancers and premature aging.
When it comes to sun protection, one of the most common misconceptions is that you don't need to wear it indoors. Unfortunately, that's not true. And given that we're all about to be stuck inside for the foreseeable future to prevent the continued spread of COVID-19, it's time to set the record straight on this matter once and for all.
Do You Need to Wear Sunscreen Indoors?
The short answer is yes. UV rays can pass through glass windows. Because of this, it’s important to wear SPF inside your home, as well as inside your car. In fact, the vast majority of UV hand aging occurs while driving, so applying an SPF-infused hand cream is a great option for those looking to protect their skin and prevent early-onset fine lines and wrinkles.
Glass windows do filter out UVB rays however UVA rays can still penetrate through your windows which is harmful to your skin. According to our dermatologist, UVA rays actually penetrate a deeper layer of skin and are therefore more damaging than UVB rays. In fact, UVA rays are the root cause of hyperpigmentation, skin cancer, and premature aging. All this is to say, even if you plan to spend an entire day indoors, topping off your skincare routine with a final layer of SPF is a stellar, supremely necessary idea.
Do You Need to Reapply When You're Indoors?
According to Dr. Ingky, advise reapplying sunscreen every two hours. That said, if you’re indoors and away from windows, the need to reapply is less necessary. When you're indoors, you're less likely to be sweating or swimming, so your sunscreen is also less likely to be compromised after its initial application when you're indoors. But let it be known, that doesn’t mean you should forego SPF and re-application altogether.
