MAC Obviously Bare is a very warm-toned, medium-dark beige with a pearl finish. It is a permanent lipgloss that retails for $19.00 and contains 0.1 oz.
MAC Obviously Bare Lipglass ($17.00 for 0.10 fl. oz.) is a muted, light-medium brown with warm undertones and fine, white pearl. It appeared lighter applied than swatched for me, and it had a milkier quality to the look of it so that some of the color gathered into my lip lines as milky glosses often do. It was very smooth in feel, and it spread easily across the lips, but it just lacked the evenness that would make it standout. This sahde wore well for four and a half hours on me.
The Lipglass formula is supposed to be "pigmented, very shiny and can impart subtle or dramatic color" that can be worn "on its own, over lip pencil or lipstick" and will "condition lips." MAC could use an update on the description as some shades are more pigmented than others but several are sheerer and likely intended to be that way. The formula has a very glossy, high-shine finish with a light-medium weight and moderate tackiness. I find that newer Lipglasses (over the last couple of years) are smoother and not quite as tacky as the formula was many years ago. They wear from three to six hours on me and are usually lightly hydrating. MAC recently updated the shade range and packaging for the range (though the formula was said to be unchanged), so worth noting is that with that packaging change came a reduction in quantity to 0.10 fl. oz. (was 0.17 fl. oz.), which may matter for some but not everyone.
