Need assistance to determine what type of acne this is and a treatment plan!

Hello my fellow Esties! I need some help determining what type of acne my client is dealing with. This has been my client for around a year and her skin has had a huge breakout in an area that’s not common for her. I believe this is hormonal acne possibly some stagnant lymph as well. I would love your thoughts and any tips you can offer me. Possibly a treatment plan based on the photos posted.
