Designed for lash pros and beginners alike, DUO's Line It Lash It in Black is a game - changer. This 2 - in - 1 product offers a smooth glide on your lash line. With its intense black shade, it creates well - defined and prominent eye makeup that lasts all day or night. The fine - tip applicator brush helps you draw a thin, pigmented black line precisely, even on your first try. It's like getting lash extensions as easily as applying eyeliner.
It serves dual purposes. When wet, it acts as a lash adhesive, and when it dries, it becomes a great eyeliner. It makes your eyes look bigger and is perfect for smoky makeup. You can create your desired looks in one go, ideal for those who want dramatic yet natural - looking eye makeup without spending too much time.
This long - wear makeup option has a non - irritating formula. It can stay put for hours without retouching. The powerful and innovative formula gives an instant lash boost while still feeling like natural lashes. It's lightweight, non - sticky, waterproof, tear - proof, and can hold up through sweat and sudden eye movements.
It's also safe for sensitive eyes and skin. It's water - resistant, odorless, hypoallergenic, and free of harmful ingredients. One swipe gives you both glue and line effects, meaning less stuff on your lids.
Applying it is quick and easy. For pros, it's a new best friend. It ensures accurate lines and fast, clean lash application. Just slap on a strip and draw a line with the adhesive eyeliner for a stronger hold, saving you time for more fun.

To use this product, first make sure your lids are clean and dry. You can use a primer for the best results. Apply 2 coats of the adhesive eyeliner along the upper lash line. While the liner is still semi - wet, place the false lashes on it and gently press down to secure. If you need to reposition the lashes after the adhesive eyeliner has dried, slowly peel off the lashes, clean the residue, and reapply a fresh coat of the adhesive eyeliner.
When it's time to remove the lashes, start at the outer corner and gently peel off the lash strip. To remove the adhesive eyeliner, gently wipe an oil - based makeup remover over your closed eyelids until they are clean.
Keep this product out of reach of children. If you have a pre - existing eye condition, consult your doctor before using it. If irritation occurs, stop using it and consult your doctor. Only use it as directed and for external use only. Don't wear the adhesive eyeliner in or near an MRI machine. Also, we recommend doing a patch test before continued use. If any redness or itching occurs, stop using the product.
