The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
recall that you know when you are exposed to UV um and especially especially UVB um the epidermis has to thicken it's a defense mechanism and there's a decrease in the amount of extracellular Matrix protein so collagen as a result of this and it's probably due to UV related increases in the expression and activity of the um the pro proteins and enzymes responsible for the degradation of the ECM
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

but it also — injures collagen particles, elastin particles, a lot of the ultra structure of not only the cell, the cells have intracellular infrastructure but also extracellular infrastructure. So the matrix of the subcutaneous tissues, the dermis is built by this beautiful scaffolding. If you look at an 18-year-old skin under the microscope, it's this thick, beautiful blanket layer of of of volume because you've got this collagen elastin structure that's holding this whole thing up and it's filled with water molecules that are have lots of space to move around in and signals going back and forth. So all of that collagen elastin framework also gets heavily injured by UV over time and it becomes cumulative and that leads to you know thinning of the skin loss of the subcutaneous fat layer loss of those in intracellular connections so that people start to get pitting and fine lines and wrinkles and so that's just from an aesthetic standpoint just another area just to know from from UV damage.
