Your symptoms suggest a combination of mild acne, post-inflammatory hyperpigmentation, and perhaps mild skin irritation. These are very common and manageable. For the itching and red patches, a gentle ceramide-based moisturizer or a mild, short-term over-the-counter hydrocortisone cream can provide relief. For pimples and dark spots, topical azelaic acid is an excellent generic option because it treats both acne and dark spots simultaneously. Always wear a broad-spectrum sunscreen daily to prevent dark spots from worsening. Avoid harsh scrubs. Please consult a dermatologist for a personalized evaluation, especially for the sensitive skin around your eyes.
