Acne is a disorder of the hair follicles and oil glands (sebaceous glands). The sebaceous glands secrete oils (sebum) to keep the skin moist. When the glands get clogged, it can lead to pimples and cysts. For personalized dermatology in Jacksonville contact our office 904.731.8300 to schedule an appointment, we will consider your age, overall health, the severity of your condition and other factors in determining what treatment is best for you.
Fungal infections of the skin are very common and include, Ringworm, Yeast infections and Tinea Versicolor. Ringworm: Different fungi, depending on their location on the body, cause ringworm. It is caused by a fungal infection-not an actual worm. Fungi on the skin, hair, and nail bed are called dermatophytes.
Also called hyperhidrosis, can affect the entire body, but usually occurs in the palms, soles, armpits, and/or groin area. Excessive sweating is normal when a person is anxious or has a fever. However, when the condition is chronic, it may be hyperhidrosis or it can signal thyroid problems, low blood sugar, nervous system disorders, or other medical problems.
Mohs surgery is a precise surgical technique used to treat skin cancer. During Mohs surgery, thin layers of cancer-containing skin are progressively removed and examined until only cancer-free tissue remains. Mohs surgery is also known as Mohs micrographic surgery. The goal of Mohs surgery is to remove as much of the skin cancer as possible, while doing minimal damage to surrounding healthy tissue.
Rosacea is a common chronic skin condition that usually only affects the face and eyes. Occasionally, the neck, chest, or other areas may be involved. Characterized by redness, pimples, and broken blood vessels, rosacea tends to begin after middle age (between the ages of 30 and 60). It is more common in fair-skinned people and women in menopause.

I just affiliated with Dr. Rosario as we just moved to the area. The staff was very pleasant, no attitudes which was wonderful. So often the staff for Doctors can drive you away from a great physician. As far as Dr. Rosario, he has a nice personality, and his credentials are A+. Based on his Bio, he stays current with his specialities, so critical. I would certainly recommend him.

I was recommended to FCD by a friend whose had quite a few cancers spotted, biopsied and removed. The doctors are friendly and very thorough, which is what you need when going for your annual visit. And if you don’t do an annual dermatology visit, you really should, and you need a good doctor (which you can find here!) Early detection is key! The wait at FCD is never long, the office is clean and the staff is very kind and professional.

I have been going here for years. Dr East and her staff also Dee and Amy are the most compassionate people I know. They are very professional but always go the extra mile to help me out. The ladies at the front desk are always pleasant and that continues to the back. I would highly recommend them. They truly care and this is hard to find these days.

I have the upmost respect for First Coast Dermatology. Ashley East and the rest of the staff are professional and very knowledgeable. Ashley can spot a problem immediately and will take steps to take care of the problem. They are respectful too.

My mother, spouse, and myself have been going here for more than a decade. They listen to patients and respond with the appropriate protocol or therapy. They never push, but allow you to make your best decision with their counsel!
Highly recommended!

Going to the doctor is never fun but Dr. Rosario and his team have figured it out. Little to no waiting means patients are more at ease and the team’s personal yet always professional care makes for an overall great experience. There is not a better group in the state.

This is my second annual visit for screening. Appointments are met on time, visit with Ashley and her assistant is comfortable, thorough and any minor issues are immediately addressed. I could not ask for a better experience.

Like this place very much! Clean and comfortable and every one that I have come in contact with has been very friendly.
Love Dr. Harris. She makes you feel comfortable and most importantly, "she listens" to what your problems are

Excellent experience each visit. Check ups are very thorough. Both times, I felt extremely comfortable and absolutely treated with the BEST of care for cyst and skin tag removals. Would highly recommend Dr. Ashley and her crew to anyone needing skin healthcare.
