Hi i am 25 years old i started shaving my bikini are and now i have brown spots and ingrown hairs with razor bumps how can i remove them?

Stop shaving...: ... practice good skin hygiene and skin preparation prior to shaving, buy new razors, clean and store your razors properly (on a dry surface, not in the shower/tub), and schedule an appointment with a Dermatologist for evaluation and consultation. You may have skin that just needs more TLC and possibly developed folliculitis. This is very common and a good Dermatologist will help.
