If you hang around the YouTube beauty community, you probably have heard the name Kathleen Lights. Kathleen is one of the most popular beauty gurus currently on the site, charming viewers with her bubbly nature, adorable dogs, and candid chats about her life and anxiety issues. I personally think she's great and has had a great track record curating collections and colors in her brand collaborations. And as things seem to go lately with the big name YouTubers, Kathleen launched her own brand in recent months, a nail polish brand called KL Polish.
