MAC Sin is a slightly cool-toned, medium-dark burgundy with a cream finish. It is a limited edition lipgloss that retails for $19.00 and contains 0.1 oz.
MAC Sin Lipglass ($16.50 for 0.17 fl. oz.) is described as a "deep blood red." It's a deepened, muted red with subtle, warm undertones. It had semi-sheer color payoff that went on really unevenly with both streakiness and a lot of color settling into lip lines. This shade lasted for four and a half hours on me and feathered.
