Jennie Garth responded to critics who said she has gotten "too much Botox"

Jennie Garth‘s latest Instagram selfie had her followers questioning whether she’d had “major plastic surgery” or “too much Botox” — criticisms to which the 46-year-old actress swiftly responded.

Garth shared a photo of herself smiling and posing next to her Beverly Hills, 90210 costar Tori Spelling, as the two visited Israel to film a commercial for a Castro Kids fashion event.

“Working with my favorite partner in crime!” Garth captioned the pic of herself and Spelling, 45, on Monday. “Thank you @castrofashion @castrofashion_kids #israel We ❤️Israel @90210onfox @torispelling.”

Critics soon began commenting on Garth’s post, and to many of the remarks, Garth left sarcastic observations of her own.

“Oh Jennie! You are beautiful and don’t need all that Botox! Sadly you are unrecognizable here!” wrote one critic, to which Garth wrote back, “Thank you?”

“Omg what happened to your face?” another said, prompting laughter from Garth. “Ha you’re amazing,” she said.

Only one troll seemed to garner a sincere response from Garth. “Omg! You seem so fake …” wrote a Garth follower, Garth responding, “Nope, I’m human.”

She later sent a fan who defended her a kissy-face emoji.

“You know, some of our favorite people who we looked up to growing up are kind enough to share their lives with us and all you people can do is get on here and put them down,” Garth’s fan wrote. “I’m disgusted really. They don’t have to share anything with us. They do it because they want to interact with their FANS. And then to see all these disgusting and negative comments. If you people don’t like their faces or them then why are you following and commenting on their damn Instagram pages. Get a life.”

Garth’s latest clapback comes weeks after she defended herself against those who criticized her for not posting a tribute on social media to her late costar Luke Perry after his sudden death.

Though the What I Like About You alum had shared an exclusive statement about Perry to PEOPLE, she had remained silent on Instagram — only posting a sweet photo of daughters Luca, 21, Lola, 16, and Fiona, 12 in honor of International Women’s Day.

Responding to the flood of negative comments that came her way, Garth set the record straight about her feelings.

“I chose to post a pic of my girls today. Because they are my life. Because today is a day to celebrate all women,” Garth wrote in the comments. “It took a lot for me to want to celebrate anything. I thought about it and I know that’s the way my dear friend would have wanted it. His kids were his life. And anyone who knew him knows that and knows he didn’t give a f*#k about social media.”

“So please don’t assume or judge or make rude comments,” she continued. “That’s really uncool. Sincerely, Jennie.”

Perry famously starred as Dylan McKay on the iconic ’90s television series. (He appeared from 1990-95 and again in 1998 until 2000.) He died in March at the age of 52 after suffering a massive stroke days earlier.

Though Perry stayed in touch with his Beverly Hills, 90210 costars, he had not signed on to join the upcoming highly anticipated Fox reboot — which was announced the same day of Perry’s stroke.

The six-episode revival is set to air this summer. Garth and Spelling will both be back, as will original stars Jason Priestley, Brian Austin Green, Tori Spelling, Ian Ziering and Gabrielle Carteris.
