- Basal Cell Carcinoma (BCC): The most common type of skin cancer, typically slow-growing and arising from sun-exposed skin, appearing as a pearly or waxy bump, flat flesh-colored or brown scar-like lesion, or a bleeding/scabbing sore.
- Lipomas: Benign tumors composed of fat tissue, usually soft, movable, and painless, located just beneath the skin.
Acne, Rosacea & Follicular Disorders
- Hormonal Acne / Adult Female Acne: Acne linked to fluctuations in hormones, often presenting in adult women along the jawline, chin, and neck, and may persist beyond teenage years.
- Hidradenitis Suppurativa (Acne Inversa): A chronic, recurrent inflammatory skin condition featuring painful, deep-seated lumps, abscesses, sinus tracts, and scarring, typically in areas where skin rubs together (axillae, groin, under breasts).
This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Ashley O'Toole.
- Excision of Benign Lesions (Moles/Nevi, Cysts, Lipomas, Skin Tags, Seborrheic Keratoses): Surgical removal of non-cancerous skin growths for medical reasons (e.g., irritation, inflammation) or cosmetic purposes, with pathological examination if indicated.

- Microneedling (Collagen Induction Therapy) & Radiofrequency (RF) Microneedling: Procedures that create controlled micro-injuries in the skin to stimulate collagen and elastin production, improving skin texture, reducing scars (acne, surgical), fine lines, and stretch marks. RF Microneedling combines microneedling with radiofrequency energy for enhanced skin tightening and rejuvenation.
