Kardashian disclosed that Beverly Hills cosmetic dermatologist Dr. Simon Ourian lasered off some of her stretch marks, although she did not specifically point out the treated area or areas.
"I feel so excited that I finally did it," Kardashian said on Snapchat, according to E! News. "I've been so scared to do it, like 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!"
The reality TV star was spotted leaving Epione Beverly Hills, a cosmetic surgery office popular among celebrities that specializes in aesthetic procedures, early Sunday morning wearing a black hoodie, black leggings, white sneakers and sunglasses.
In order to permanently remove stretch marks, Ourian reportedly cools the skin and then uses a CoolBeam laser to vaporize superficial cells. The procedure removes 10 millionth of an inch of skin at a time, costs anywhere between $2,900 and $4,900 depending on the body part and requires several days of recovery time.
Ourian had reportedly performed a similar procedure on Kardashian's breasts in 2014, which was documented on a previous season of her family's reality show.
Kardashian also tightened up the skin around her belly button a little over one week ago without actually having to go under the knife.
"So I'm spending my Saturday with Dr. Ourian and it f-cking kills. Aaaah! But it will be worth it," Kardashian reportedly said on Snapchat.
"You guys, I never thought I could love someone and hate someone so much at the same time. 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 around your belly button so that it can look back to normal."
Kardashian also appears to receive lip fillers and Botox injections regularly, although she refuses to get any work done while pregnant.
Kardashian is mom to two kids -- North, 3, and Saint, 14 months -- with husband Kanye West.
