Eventually, Jenner was forced to make an apology in a series of tweets from her corporate account:
I care a lot about the quality of my products. As you can see from my matte lips..
I changed my entire matte formula in the first month to be less dry and thick...
And I changed the wand to be more comfortable because I listen to you guys, and I love perfection. So good or bad, I love hearing your feedback.
When I saw the problem with my lip gloss brushes I stopped all production and changed it. Life is a learning experience and we learn from our mistakes.
