I use gelatin to remove blackheads. Not only does it work well but it's also much more affordable than blackhead removing strips. A single packet of lasts me a long time.
But flavored gelatin should not be used, I buy the plain one from the grocery store. I heat up a little bit with water in the microwave as the article said and apply it on my nose, chin and forehead. It takes a while to dry so a little bit of patience is needed. But when I peel it off, I can see that it has removed all of the blackheads.
