Since opening his private practice in 1975, Dr. Arnold William Klein has offered the very best in dermatology and cosmetic surgery. Widely regarded as the father of modern cosmetic dermatology, he pioneered the field of minimally invasive aesthetics and developed the injection techniques for Botox, Collagen, and Restylane.

Dr. Klein realized the value of skin's beauty at a very early age, when he suffered severe burns, causing him to wear long sleeves until he turned 21 years old. The burns also opened his eyes to aesthetics, as he began to envision and appreciate various forms of beauty. In the 1960s, under the influence of Andy Warhol and Louie Kahn, he developed a love of the visual arts. When he came to California for his internship, he met a seminal group of artists -- including John Baldessari, Frank Gehry, Robert Graham, Ed Rusha and Ed Moses -- that further influenced his perspective on beautiful forms, especially the human face. His precise, refined technique reflects this artistic sensibility and makes him unique among cosmetic dermatologists.
Not only does Dr. Klein run a very busy, prestigious practice, he also volunteers as a Professor of Medicine and Dermatology at the David Geffen School of Medicine at UCLA. Additionally, the UCLA Division of Dermatology named an endowed chair in his honor in 2004.
In 2010, Dr. Klein was named a consultant to the FDA.
Throughout his career, Dr. Klein has been deeply involved in philanthropy. In the early days of the AIDS crisis, Dr. Klein was one of the first physicians to diagnose a case of Kaposi’s sarcoma in Southern California. Since then, he has been an ardent supporter of AIDS causes. In 1985, along with David Geffen, Dr. Mathilde Krim and others, Dr. Klein founded the American Foundation for AIDS Research (amfAR) in the living room of his Los Angeles home. He continues to serve amfAR today as a founding director.
In 2007, in honor of his friend Dame Elizabeth Taylor, Dr. Klein helped establish the Elizabeth Taylor Endowment for the UCLA CARE Center, a renowned facility for HIV/AIDS research and treatment. In November 2008, an article in L’Uomo Vogue reported that Dr. Klein and the organizations he founded have raised more than $274 million for HIV research and care.
Dr. Klein also serves as a trustee to various boards of directors, including the Jennifer Jones-Simon Foundation and The Hereditary Disease Foundation. The HDF discovered the first gene for Huntington’s chorea. Dr. Klein, along with his longtime friend Frank Gehry, works with the foundation to raise funds and awareness for inherited diseases.
Dr. Klein also co-founded the Rose Tarlow-Arnold W. Klein Breast Cancer Foundation at UCLA to provide breast cancer treatment for individuals who are unable to afford it.
A prolific writer, Dr. Klein has published more than 150 scientific papers in such prestigious peer-reviewed journals as the New England Journal of Medicine, Science Magazine and JAMA. He has written four medical textbooks, including his most recent, Tissue Augmentation in Clinical Practice, second edition. Additionally, he has written numerous textbook chapters on cosmetic dermatology, soft tissue augmentation, aesthetic surgery, and botulinum toxin. He has also served on the editorial board and as an expert reviewer of numerous national and international medical publications, including the Journal of Plastic and Reconstructive Surgery, Journal of the American Academy of Dermatology, Dermatologic Surgery, Archives of Dermatology, Aesthetic Surgery, Aesthetic Buyers Guide, British Journal of Dermatology andthe Journal of Cutaneous Aging and Cosmetic Dermatology.
