I have tried almost every strip lash adhesive under the sun. I used to love DUO adhesive back in the day until I developed a horrible allergy to latex. Which might I add is in SO MANY lash adhesives. It has become slightly easier over the years to find latex free glue, but there have not been many that really impressed me. I was at Sephora the other day and ran across this DUO brush on adhesive that is latex and formaldehyde free. I usually prefer to use black adhesive but they only had this in clear. I quickly snatched it up and have been loving it ever since. Only a small amount is needed to keep my lashes in place for hours and it’s also super easy to remove and does not pull out my real lashes, which is a huge plus!
