Amber glass

Also written as brown glass, UV glass, light-blocking bottle.

Glass coloured through the body rather than sprayed, filtering a portion of visible and ultraviolet light.

What it needs from a bottle

The cheapest real protection for a light-sensitive formula. Amber is doing a job, not a look, which is why it survived every aesthetic cycle in this category.
