Medical Dermatology
Our office provides comprehensive medical dermatology for Missouri residents. We treat acne, perform skin cancer screenings, evaluate and remove moles, and manage chronic conditions such as eczema, psoriasis, and rosacea. We also treat warts, cysts, and other benign skin growths. Every diagnosis and treatment plan is tailored to the individual, with a focus on long-term skin health and evidence-based care.
Cosmetic Dermatology
We offer cosmetic dermatology services designed to enhance natural features while maintaining balance and expression. Treatments include dermal fillers for facial restoration; acne scar treatments such as subcision, microneedling, and laser procedures; and laser treatments for pigmentation and sun damage. Each cosmetic consultation includes personalized recommendations based on your goals, skin type, and desired downtime. Results vary, and a consultation is required.
Surgical Procedures
Our practice provides advanced surgical dermatology with careful attention to both medical precision and cosmetic outcome. We perform skin cancer excisions, cyst and lipoma removal, scar revision procedures, and reconstructive repairs when needed following skin cancer removal or trauma. Dr. Beal’s fellowship training in facial plastic and reconstructive surgery allows for thoughtful repair techniques that aim to preserve both function and appearance.
Mohs Surgery
For certain types of skin cancer, Mohs Micrographic Surgery may be recommended. Dr. Beal is fellowship-trained in this specialized, tissue-sparing technique that enables precise removal of cancer while preserving as much healthy tissue as possible. During the procedure, tissue is examined under a microscope in real time to ensure clear margins before reconstruction. When appropriate, repairs are completed the same day to optimize healing and cosmetic outcomes.
