She continued: "For over a decade now in photos, every single flaw and imperfection has been micro-analyzed and made fun of to the smallest detail and I am reminded of them everyday by the world. And when I take that criticism to use as motivation to get myself in the best shape of my life and to even help others with the same struggles, I am told I couldn't have done it through hard work and I must have paid for it all.
"You never quite get used to being judged and pulled apart and told how unattractive one is, but I will say, if you hear anything enough then you start believe it.
This is an example of how I have been conditioned to feel, that I am not beautiful enough just being me."
The Good American founder doesn't see anything wrong with enhancing her photos to look her best and vowed to continue to do so.
She wrote: "I love a good filter, good lighting and an edit here and there. The same way I throw on some make-up, get my nails done, or wear a pair of heels to present myself to the world the way I want to be seen and it's exactly what I will continue to do unapologetically.
"My body, my image and how I choose to look and what I want to share is my choice. It's not for anyone to decide or judge what is acceptable or not anymore."
Khloe ended her lengthy post by reassuring her followers they are all "unique and perfect" in their own way.
She concluded: "For those else who feel the constant pressure of not ever feeling perfect enough, I want you to know I see you and I understand.
"Everyday I am told by my family and friends who love me that I am beautiful but I know that it needs to be believed from within. We are all unique and perfect in our own way. Whichever way one chooses to be seen.
"I have realized that we cannot continue to live life trying to fit into the perfect mold of what others have set for us. Just do you and make sure your heart is happy.(sic)"
