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.

If something on your skin is bothering you—persistent, painful, changing, or simply uncertain—it’s reasonable to get it checked. We can evaluate and guide you on the next steps.

Second opinions are welcome. If you have prior records, biopsy results, or photos, bring them along—we’ll incorporate that information into your visit.

Bring your ID, insurance card (if applicable), a medication list, and any relevant history. If you’re concerned about a specific area, note when it started and any changes you’ve observed.

We work with many insurance plans. Coverage varies, so the best next step is to call, and our team can help verify your plan details.

This is one of the best Dermatologist buildings around here in Troy. I don't have to travel very far and the staff as well as the doctors are the most considerate and very polite. I would recommend any one to go here if they have any problems with their body according to cancer or any other problems with their body. They get you in and out as soon as they can! I just can't say enough of how proud I am that I decided to go to them.

This office is wonderful! Dermatologists are notoriously difficult to get in to timely, St. Louis Dermatology in Troy is so easy to get an appointment at (the “longest” I’ve waited is a week for a non-urgent appointment). Kayleigh is an excellent provider, remembers your previous visits and concerns, and doesn’t rush through the appointments. The in office procedures they offer as well are very convenient and often saves you on your out of pocket costs with insurance when the in office procedures are billed with your office visit. So grateful to have such a great local derm!

I absolutely love this office. They handled my surgery with exceptional care, and I can finally say I’ve found the right team. I drive 55 minutes for every appointment because Dr. Beal and his staff are truly outstanding. Their professionalism, compassion, and commitment to patient care make the trip more than worth it. I always feel supported and confident that I’m receiving the best possible care. Highly recommend!
