United Kingdom, Oct. 26 -- Hailey Bieber "made a commitment" to herself not to consider Botox injections until she's in her 30s.

The Rhode Beauty founder admitted she has used the injectable to treat her temporomandibular joint (TMJ) disorders, as it is seen as an option for pain management, but she won't think about having wrinkle-smoothing jabs for the foreseeable future.

Speaking to Owen Theile on his In Your Dreams podcast, the 28-year-old beauty said: "I don't have any Botox except for in my jaw for TMJ, but I have no Botox in my face.

"I made a commitment to myself that I wasn't going to do any Botox until I was in my 30s. When I get there, I'll see if I even want to do it."
