Walk through any new cosmetics flagship and you will notice the walls glow. Edge-lit glass shelves have become the default presentation for skincare and makeup, for a simple reason: even, glare-free light makes packaging colors read accurately, and color is what cosmetics customers buy.
The trend is no longer limited to flagships. Retrofitting an existing wall takes about a day per run: shelves swap to edge-lit glass, a slim driver box hides above the top shelf, and existing wiring usually suffices. Compared with repainting and re-lighting the whole wall, it is the highest-impact upgrade per dollar we install.
