Ex-UFC fighter Pearl Gonzalez is switching up her look ... 'cause she's decided to get her boob tattoo removed.
The Chi-Town Princess revealed the big change on Tuesday ... saying it will be a long and painful process, but she's in it for the long haul.
Pearl -- who has several tattoos -- has had some ink of clouds with a moon on her right breast for years ... but says after 11 sessions, it will be gone for good.
Gonzalez -- who also competed in Bare Knuckle FC and Invicta FC -- posted video of the process ... wearing a white bra as a removal specialist takes a laser to the area.
When asked if getting the tat or the removal hurt more, Pearl said it's a lot more painful to get it removed -- OUCH!!!

No word on what her next move will be tat-wise, but she still has the rest of her collection!!
