Kim Kardashian West has had her stretch marks removed

Kim Kardashian - who has North, three, and Saint, 13 months, with her husband Kanye West - has undergone a procedure to remove her stretch marks and feels so relieved she's had it done after being "scared" about the procedure for months.

Speaking in a video on Snapchat, she said: "I feel so excited that I finally did it. I've been so scared to do it thinking it hurts so badly, and it didn't hurt that badly. So I'm so grateful, and I'm so excited. I love you Dr. Ourian."

To remove stretch marks, Ourian cools the skin and uses a CoolBeam laser to vaporise superficial cells, removing 10 millionth of an inch of skin tissue at a time. The procedure costs between US$2,900 and US$4,900 per area and the patients typically recover within a few days. The results are permanent.

A week earlier, Kim had Ourian tighten the skin around her belly button—without actual surgery. She posted a video of her visit on Snapchat.

"So I'm spending my Saturday with Dr. Ourian and it f--king kills. Aaaah! But it will be worth it," Kim said.

"You guys, I never thought I could love someone and hate someone so much at the same time," she added. "If anyone who had babies understands what it does to your belly button...then you really understand how much you need Dr. Ourian to tighten [the skin] around your belly button so that it can look back to normal."
