Stop Tint From Spreading
When tinting your lashes or brows placing a thin layer of petrolium jelly around the area prevents from the tint smudging and marking your face unnecessarily. It can be super embarrassing to have a black stained mark somewhere on your face. Especially if you are doing this by yourself take any and every precaution necessary.
Decorative Detailing Added
Yup, it can even be used for decorative purposes. Using a container of the product after the first coat or before depending on the effect you want, brush some vaseline on the wall- the vaseline will not allow the paint to latch thus creating a two-tone pattern. A really interesting pattern can be crested too.
