@drmaraweinstein: Check the link below for my latest YouTube video! For my entire life a specific type of light has been quietly aging my skin, and until new research presented at the 2026 American Academy of Dermatology conference, we had no idea how much damage it was doing. In this video I break down UVA1 radiation, the long-wave UVA between 340 and 400 nanometers that Kenvue's data links to about 80 percent of visible photoaging, and why the SPF 50 you reapply religiously is protecting you from sunburn but not from the deep collagen damage that makes skin look older.
