Brazalian Wax Will Using Alcohol/astringent After Shaving Your Bikini Area Prevent Bumps?

Will using alcohol/astringent after shaving your bikini area prevent bumps? - brazalian wax

Is it painful? Any other solution?

I had a bad experience with waxing (brazalian 2 days before my wedding and I've beaten everywhere), it is not clear, dass I'm nervous to use a cream to dipilatory.
I use shaving gel and Razor Burn always bumps when the hair begins to grow again
