Tinting basically creates the illusion of mascara without you actually having to swipe it on.
Think of lash tinting as a semi permanent dye job for your lashes.
Tinting won’t add curl, length, or volume to your lashes (you’ll need to try a lash lift or lash extensions for that), but it will darken and intensify their colour with permanent, cream-based dyes (and in some cases, a semi permanent vegetable-based dye). If you have naturally light or blonde lashes, you’ll definitely see the most dramatic difference with a tint.
