This lab study found that retinyl palmitate (a vitamin A derivative) protected skin cells from UV damage by reducing collagen breakdown, decreasing inflammation markers like IL-6 and TNF-α, and helping cells repair themselves. The research suggests it works through multiple pathways—basically telling your skin cells to make more collagen, calm down inflammation, and stay alive longer when exposed to UVB rays.

Researchers tested retinyl palmitate on skin cells in a lab, using various lab techniques (immunofluorescence, cell migration assays, gene analysis) to measure its effects on UV-damaged cells. They didn't test this on human skin or in real-world conditions.
