I got this set from ASOS here. It's £23.50 for the cult favourite box blush Hoola bronzer and includes sample sizes of Cha Cha Tint and Watts Up! highlighter.
Cha Cha tint is a mango coloured lip and cheek tint, I love me an orange lip! so a stain is perfect.
Unlike Posie Tint and Bene Tint I find Cha Cha Tint easier to work with on the cheeks, it blends out beautifully and when added lightly adds a bit of warmth, but when added a bit more heavily adds a pop of colour.
(Cha Cha Tint heavily swatched and blended out)
Cha Cha tint is probably the most consistent of the tints. I found that it was hard to get Bene Tint and Posie Tint to apply on the lips without streaking. Cha Cha Tint applies quite evenly.
I think it would be harder to get a completely even coat of these lip stains due to the really liquidy texture and the condition of your lips at the time. I like to prep my lips prior to applying and after the stain has dried putting lip balm over it.
Have you tried any of the Benefit tints? What are your thoughts?
