Rashes

A rash is more than just a skin irritation; it is often the body’s way of signaling that something is out of balance. Because "rash" is a broad term covering everything from a simple allergic reaction to complex systemic conditions, getting an accurate diagnosis is essential for effective treatment. At New Wave Dermatology and Laser, Dr. Hedayati uses a meticulous, diagnostic approach to identify the root cause of your skin inflammation and provide rapid, soothing relief.

Understanding the Many Faces of Rashes

Understanding the many faces of rashes

Contact Dermatitis

An allergic or irritant reaction to something that has touched the skin, such as poison ivy, nickel, fragrances, or harsh cleaning chemicals.

Pityriasis Rosea

A common temporary rash that often begins with a single "herald patch" followed by smaller spots across the torso.

Psoriasis

A chronic autoimmune condition that causes skin cells to build up rapidly, forming thick, silvery scales and itchy, dry, red patches.

Hives (Urticaria)

Itchy, raised welts that can be triggered by foods, medications, stress, or environmental factors.

Seborrheic Dermatitis

Often affecting the scalp, face, and chest, this condition causes scaly patches, red skin, and stubborn dandruff.

Fungal & Bacterial Infections

Rashes caused by organisms like ringworm (tinea) or impetigo, which require specific anti-infective treatments.

Drew Park

“Dr. Hedayati is a fantastic doctor! He is extremely attentive, highly knowledgable and very professional. I also appreciated his clear communication style. I arrived at his office, which is well kept and designed very tastefully. His front office staff is great. They themselves were extremely helpful and personable. The sign in system is smooth and easy to use. And I can say I received top of the line care during the appointment with Dr. Hedayati himself.”

David R.

“I had an exceptional experience with Dr. Hedayati and his team. The level of care was outstanding from start to finish. My Botox treatment was completely painless—truly a testament to his skill and precision. He answered all my questions not only about my aesthetic goals, but also about my dermatologic needs. He is a true expert. Separately, the office itself is beautiful: modern, sleek, and fully electronic, which made the entire check in process seamless. The staff were equally impressive—knowledgeable, personable, and genuinely warm and welcoming. I felt very well taken care of and will absolutely be returning for more. Highly recommend and cannot wait to go back!”

Irene and Amir

“As a first time patient, I was nervous and had a lot of questions. Dr. Hedayati was incredibly patient and took the time to answer every single one. He didn’t just suggest what he thought I needed, he clearly explained the why and how it would benefit me. He made sure I felt fully informed and comfortable before moving forward with the procedure. The treatment itself was practically painless, and from the moment I walked through the door, the entire experience was extremely pleasant. The staff is warm and welcoming, and Dr. Hedayati is truly an excellent dermatologist. I am already looking forward to my future appointments at New Wave Dermatology.”

Dakota Collins

“From the second I walked into this office the whole staff was amazing, it felt more like a concierge visit than a typical check up. Dr. Hedayati was awesome, he was very thorough and explained things to me in a way I could actually understand, giving me time to ask questions and feel heard as a patient. He also talked to me about daily habits I could incorporate into my routine so I could take steps to prevent issues from forming in the first place, something I really appreciated. I highly recommend him to anyone looking for a dermatologist who will give you honest expert advice and is patient centric not pocket centric.”

Nader Hashemian

“I would recommend New Wave Dermatology to anybody who is seeking a modern, clean, high-tech dermatology practice with top-of-the-line equipment and highly trained, top-tier providers. Dr. Hedayati, in particular, is incredibly knowledgeable and patient with my (sometimes excessive) questioning. He and the rest of the staff made me feel comfortable and confident that I was in good hands, which was a notable contrast from some of my prior experiences at other practices. I would not hesitate to send anybody to Dr. Hedayati.”

Arash G.

“I recently visited New Wave, a new laser clinic in Newport Beach and it was amazing! I've tried different laser clinics around the area, and New Wave is by far the best. As soon as you walk in, you will appreciate the clan and modern aesthetic, and the staff is truly outstanding. I felt like they really cared about my needs and we're not just trying to sell me services. I've had fantastic results! - the best I've ever had from a laser clinic and I will definitely continue to go back!”

Helen Kamali

“I’m incredibly particular about who I trust with Botox. It’s important to me to see someone who isn’t just an injector, but a physician with a deep understanding of how everything works together to impact my skin, my face, and my long-term results while still respecting my personal aesthetic and cosmetic goals. Dr. Hedayati absolutely nailed this. His approach is modern, thoughtful, and deeply rooted in knowledge. It was genuinely refreshing to work with someone who wasn’t a “yes” person, but instead took the time to explain why certain things would or wouldn’t work and offered smarter alternatives to achieve what I was really looking for.His office truly feels like an oasis, and the entire experience felt elevated, intentional, and reassuring. I left feeling confident in my results and even more confident in my care. I’m really looking forward to seeing him regularly, not just for injectables, but for my overall skincare needs moving forward.”

Frequently Asked Questions

You should schedule an appointment if a rash is spreading rapidly, is accompanied by a fever, is painful or blistering, or does not improve with basic over-the-counter care. Rashes that interfere with your sleep or daily activities also require professional evaluation.

Most rashes, such as eczema, psoriasis, and contact dermatitis, are not contagious. However, rashes caused by viruses, bacteria, or fungi (like shingles or ringworm) can be spread to others. Dr. Hedayati will provide clear guidance on how to protect your family while you heal.

The timeline depends entirely on the cause. Allergic reactions may resolve in a few days with the right cream, while chronic conditions like psoriasis require ongoing management to stay clear. Our goal is to provide you with a plan that offers the fastest possible relief.

As a board-certified dermatologist, Dr. Hedayati is a specialist in the "language of the skin." He doesn't just provide a "one-size-fits-all" steroid cream; he uses his medical training to differentiate between hundreds of different skin conditions, ensuring you get the correct treatment the first time.
