Whey protein for women. My question is?

My question is regarding consumption of protein powder. I am 24 years old and skinny. I recently started hitting gym. But i figured i cant eat eggs(used to eat 2 or 3 eggs a day) because i have been developing acnes on my chest and back. Since i am doing strength exercises, i have been asked to consume more food containing protein and also suggested tht i take protein powder. I am 49 kgs and 5 ft 4 inches in height. Since i cant consume eggs only option is protein powder. Is it safe as i am a woman? Any sideeffects ? I bought GNC's 100% whey protein yesterday. I thought i will take a small scoop with milk evryday after gym? Will this possibly affect my body in the long run. I stopped eating eggs because of acnes. I just want to know if whey protein is safe for women if consumed in small quantities. :( I want to gain weight but safely without any sideeffect. I read a few articles on internet which says its safe for women to take protein powder. I need a second opinion though.
