High end lipstick brands like MAC, Bobbi Brown, NARS, Estée Lauder, Lancôme, Chanel and Yves Saint-Laurent are often luxury items that the average person cannot afford to use on a daily basis.
This is where lipstick dupes (or duplicates) come in. These are affordable drugstore brands like Revlon, Rimmel, Maybelline, Wet ‘n Wild, Covergirl, Avon, Physician’s Formula, L’Oreal and Almay, to name a few. These more affordable brands can be well pigmented and are often very similar in consistency and formula to their high end counterparts. The colour match is usually very close or even 100%.
I haven’t personally drawn up any lists of lipstick dupes, but the links below contain names of dupes for most MAC lipstick colours, as well as other brands of lipstick and make-up.
