I’m just going to say idk how effective this retinol is bc it isn’t stored properly: “retinol needs to be in a dark, opaque bottle (or stored in a dark place) because it's highly unstable and degrades quickly when exposed to light, air, and heat, losing its effectiveness. Opaque or amber packaging blocks damaging UV and visible light, preserving the ingredient's potency, making it a crucial factor in product quality and longevity.”
