The reality star filmed the video in response to someone asking: "How has your skin and skin care changed since your transition?" on her website.
Acknowledging her skin certainly had changed, Jenner also admitted she had her beard removed back in the 80s, which took a lot of volume out the bottom of her face.
But moving onto the beauty brand she loves, Jenner admitted she always uses MAC products.
She said: "I think they do a great job. I love their coverage and it's been a lot of fun for me to learn makeup and how it works."
The reality star explained that before her show, I Am Cait, she had always done her makeup on her own.
But because she wants to look good on TV, she now has her own makeup artists. Jel.
