Crystal Hefner has recently revealed a harrowing cosmetic procedure that she “almost didn’t make it through.”

On Wednesday, the 34-year-old model said almost died last year while undergoing a “fat transfer surgery.”

Hefner posted a photo of herself wrapped in support bandages on Instagram and wrote, “I had a fat transfer surgery October 16 and almost didn’t make it through.”

“I lost half the blood in my body and ended up in the hospital needing a blood transfusion,” she added. “I’ve been slowly eating my way back to health since then and I am now finally feeling ok.”

A fat transfer procedure involves fat being removed from one area in the body and grafted to another area, fat cells are often injected into a woman’s breasts to increase their size or change shape.

“I advocate for being natural since I got very ill and removed my implants and everything else toxic in my body in 2016,” she continued. “I should have learned my lesson the first time but I guess the universe keeps sending you the same lesson until you learn it.”

In the post, she called out unrealistic beauty standards, stating, “Our culture is a trap and makes women feel terrible about themselves.”

“Social media makes it worse,” she added. “Advertisements make it worse. Physically fake people make it worse (I was one of them). How our culture defines beauty makes it impossible to keep up with. Women are overly sexualized. I know from the worst kind of experience.”

Hefner went on to say, “For ten years my value was based on how good my physical body looked. I was rewarded and made a living based on my outer appearance. To this day I need to write reminders of why I’m worthy that have nothing to do with my physical appearance to convince myself that I’m enough.”

She said she feels “sorry for the next generation looking up to people whose looks aren’t even attainable without lots of filters, makeup, or money and women need to stop feeding into it.”

“This is a huge slap on my own wrist for caving in to this pressure, even now in my 30’s – as I thought I would have learned my lesson by now,” she remarked of her near-death experience. The article was originally published on PEOPLE.
