Caitlyn Jenner has taken to Instagram to reveal she recently had "sun damage" removed from her nose, which she got as a result of not using sunblock.

The 'I Am Cait' star took to Instagram to share a make up free picture of herself, urging others to use sunblock, as she revealed she had to have a spot from her nose removed due to damage from the sun's rays.

She captioned the photo: "I recently had to get some sun damage removed from my nose. PSA - always wear your sunblock (sic)"

Caitlyn has been very open with her followers about what she has gone through, having underwent a gender transition back in 2015, and she previously revealed she feels "wonderful" not having any more secrets.

She said: "I don't have a secret left in my life. It's a wonderful feeling. The book is about a lifelong struggle. Everybody has their stuff. Everybody has things that they have to deal with in life, and what I've dealt with my entire life is my identity with myself as a person. To be able to share that journey with people ... feels great."

And the 68-year-old television personality believes she threw herself into sport because of her "issues with her gender".

She added: "You're not talking about sexuality - you're talking about who you are and who's in your soul. It goes through your head 24 hours a day, 365 days a year ... I grew up in the 50s and the 60s - there wasn't even a word for it. I didn't know what it was. I didn't know why. 

"Sneaking into my mom's closet or my sister's closet ... walking around when I was 9 or 10 years old ... [with] a scarf over my head so it didn't look like I was a girl ... I look back on it now and a lot of the reasons why I was so obsessed with winning the games was because of my issues with gender."
