Will face condition go back to prepregnancy once given birth?

I used to have acne/pimple prone skin. The slightest dust will cause pimple on my face. But ever since pregnant, after the first few weeks, until now 39 weeks my skin rarely get any pimple. Its the clearest ive been. However im scared once i have given birth itll go back to the same condition as pre pregnancy. Any mummies experience same thing and can share ? Did your skin condition go back to as prepregnancy? #firsttimemom
