Chances are you’ll never get another opportunity like this one: combine a free Latisse trial with a tax deduction and the knowledge that you contributed towards a child’s happiness.

Allergan, the maker of the popular, FDA-approved treatment that makes eyelashes grow longer, fuller and darker, is pushing to raise money for the Make-A-Wish Foundation, a non-profit organization that’s dedicated to granting the wishes of children with life-threatening illnesses. Actress Christina Hendricks, known for her role as Joan Holloway in Mad Men, is spearheading the campaign to raise $500,000, which would be enough to grant one wish in every Make-A-Wish chapter in America.

Allergan will double all contributions to the campaign up to $250,000, and will offer Latisse free trial certificates to the first 10,000 participants who donate $20 or more. Those who receive the certificates can bring them to their doctor to see if Latisse is right for them. By inviting two friends to make donations, participants can also receive a $20 discount towards their next purchase of Latisse.

Hendricks, who is an avid Latisse user, had this to say about Latisse and its Make-A-Wish campaign:

“I’ve always felt my lashes were short and thin, and in my profession, I wear a lot of false lashes and makeup, which take a toll…. My doctor talked with me about lashes, and I was surprised to learn that some women may notice their lashes thinning over time. Women who notice these changes in their lashes now have the option to talk to their doctor about Latisse and see if it’s right for them.

“Latisse is also a brand that contributes to children, and I couldn’t think of a better cause to support than the Make-A-Wish Foundation. When I was seven years old, I saw firsthand the difference a wish can make in the life of a child when a girl in my class got her wish to meet Erik Estrada.”
