Call them highlighter, luminizer, illuminator or whatever, the function will remain the same. To highlight and define your facial feature, creating a soft focus on the targeted spot.
I have tried quite a few, from liquid to powder type, and I have to admit I am obssesed with highlighter as of late. They are so sparkly and fine, I can resist collecting them...
Here are some of my highlighters. I have few other which I forfot to gather.
My fave of all the above would be Mary Lou and Champange Pop. I love how they are super fine compared to MAC.
In terms of color, Champagne Pop and Oh Darling is quite similar, but Champagne Pop gives a natural sun kissed tan whereas Oh Darling is more gold. Mary Lou brighthens my skin perfectly.
Betty Lou is actually for bronzer/eyeshadow, but sometimes when I dont feel like having highlights I just dabbed a little over blusher for a little highlight.
