Are you saying that you have set the meta
<title> tag to "the best tatto remover tools in 2018" using Yoast, and that the title of your post - using
<h1> tag (or whichever level is appropriate) is "tatto remover"?
If that's the case, you have no cause for concern. It's perfectly normal for the meta title to differ from the page or post title.
However, as @chrisofarabia says, you should spell-check your post - and especially your keywords - if you want any benefit from it.
