Acne exists beyond its appearance as a skin condition. While it can physically cause redness, sensitive bumps, and an uneven texture, it can also affect one’s confidence and self esteem. Knowing how our patients feel about their acne, our providers feel gratified and privileged when clearing our patients’ skin.

Acne treatment can be complex. The skin can change over time to become drier or greasier. Locations of acne can vary, as can its severity. Diet can influence acne as well. Our providers consider all of the relevant information to decide which treatments are optimal. Once the diagnosis of acne is firm, we customize a treatment for each individual patient that can involve a mix of topicals, oral medications, and lasers.

Owing to studies conducted where he completed his laser fellowship, Dr. Rosenbach theorized that the Pulsed Dye laser would treat stubborn red acne remnants. His patients were able to undergo this laser treatment years before the first research trials proved its effectiveness.

For some patients, other conditions can imitate true acne. We take great satisfaction when we can correctly diagnose and clear up a condition that for years has been mimicking acne. When this type of situation arises, sometimes the longstanding battle with pimples can be solved within a matter of weeks.
