###Human: Can hormonal changes cause pimples, red, and brown spots on the face? ###Assistant: Hi. I have seen your query. With your description, it seems you have developed grade 2 to 3 acne. See acne concentrated over chin indicate hormonal acne. If you can share a few pictures, it will be helpful in exact grading of acne, which further leads to proper treatment. You can use 1 % Clindamycin gel during the morning and use 3.5 % Microbenz gel during the night. Use face care face wash twice daily. Not to use oily spicy foods and junk foods, take lots of water daily which will hydrate your skin.
