From the doctor
"Dr. Roxanna Gangi: Eyeliner is one of the most common triggers I see for chronic lid-margin disease, especially when applied to the waterline. If a patient won't give up liner — and most won't — I want them in something developed with the lid margin in mind. Twenty/twenty's Double Duty avoids the inflammatory ingredients in conventional liners and removes cleanly with an oil-based remover. Whatever liner you wear, please apply it outside the lash line, not on the waterline above the meibomian glands."
Format: Dual-tip eyeliner pen
