Jennifer Lopez says her glow is all-natural.

The superstar, 51, has denied ever going under the knife for plastic surgery or Botox many times before and recently shut down an Instagram commenter who accused her of lying.

“But can I just mention that brows and forehead doesn’t move at all when you talk or try to express… you definitely have Botox. And tons of it. And it’s all good. Just saying,” the person commented on a video of the singer trying out her JLo Beauty That Limitless Glow face mask ($48 for three).

“LOL that’s just my face!!!” Lopez responded. “for the 500 millionth time…I have never done Botox or any injectables or surgery!! Just saying.”

She continued, “Get you some JLO Beauty and feel beautiful in your own skin!! And here is another JLO Beauty secret: try spending your time being more positive, kind and uplifting of others,” J.Lo said. “Don’t spend your time trying to bring others down that will keep you youthful and beautiful too!!! Sending you love. #beautyfromtheinsideout #beautyhasnoexpirationdate.”

The subject of Botox seems to be a touchy one with Lopez, who recently revealed that an ex-boyfriend encouraged her to try it when she was just 23.

“I didn’t like needles anyway, but the boyfriend’s like, ‘Yeah, you should start it. I do that.’ I was like, ‘No, thank you,’” Lopez recalled. “And I just wonder what would’ve happened to me if I would’ve started Botox at 23, what I would look like right now. My face would be a totally different face today.”

Rather than turn to a procedure, Lopez credits olive oil and sunscreen as two main factors to her ageless beauty.
