Sunscreen should be slathered on generously even if you’re spending most of the day indoors. This is because UV rays can pass through glass windows.
Other than protecting our skin from being damaged or burned, sunscreen also helps to slow signs of ageing and prevent the appearance of hyperpigmentation.
Now, let me paint a picture that we’re sure oily skin girls out there can relate to: our face may secrete oil throughout the day, and we might turn to oil blotting papers to soak up the grease.
Do you make sure to reapply your sunscreen after doing so? You might want to start doing that from here on out.
Claudia Christin, who has a Ph.D. in Dermatology, recently showcased the effects of blotting sheets on your sunscreen protection. She did this using UV cameras so you can get a better idea of how it works.
She switches on the UV camera after putting on her daily sunscreen. It shows her face as dark and black, which means her face is protected from UV rays.
Using the blotting papers, she slowly dabs the oil around her face. It was immediately apparent that the sunscreen is being removed.
Her face darkened face started becoming lighter and lighter wherever she dabbed. It slowly turned from black to grey, which means the UV protection was becoming lesser and lesser.
The most shocking part was when she dabbed at her forehead, which showed a large grey patch after the use of only a single blotting paper!
She then began reapplying her sunscreen, showing the stark contrast between a blotted area versus skin that is freshly coated in SPF.
This is why you should keep your sunscreen on throughout the day. Do remember to reapply it if necessary – especially if you’re going to reach for blotting paper!

For now, we’re going to go and reapply our sunscreen – just to be on the safe side.
