Description
Longer-looking, fuller-looking lashes, without prostaglandins.
New to lash serums, or moving away from a prostaglandin formula? XXtraLash is a simple way to add a gentle, prostaglandin-free step to your routine. It holds 3 mL and comes with a slim precision brush for applying right along the lash line.
XXtraLash is a prostaglandin-free eyelash serum that conditions lashes for a longer-looking, fuller-looking lash line. It pairs conditioning peptides with four bioengineered sh-polypeptides, adenosine and hydrolyzed soy protein, in a lightweight water-based formula.

How to use
Use XXtraLash twice a day, morning and night, on clean, dry skin. Sweep the brush once along the base of your upper lashes and once along the base of your lower lashes, as close to the lash line as you can, the way you would draw a very thin line of liquid liner. One sweep per lash line is enough. Let it dry before you apply makeup.
If you wear contact lenses, take them out before you apply XXtraLash and wait until it has dried before putting them back in.

When will I notice a difference?
Give it time and be consistent. Each lash follows its own natural cycle, and lashes are replaced gradually over weeks to months. That is why most people use a lash serum every day for at least 8 to 12 weeks before judging how their lashes look. Learn more in our guide to how long lash serum takes.
Why prostaglandin-free?
Many lash serums use prostaglandin analogs, ingredients related to glaucoma eye drops. These have been linked to side effects such as darkened eyelid skin, red or irritated eyes and, rarely, changes in eye color or the fat around the eyes. XXtraLash leaves them out.
