About Bay Area Dermatology

Bay Area Dermatology, operating as Bay Area Cosmetic Dermatology at weloveskin.com, is a medical dermatology and aesthetics practice located at 2299 Post Street, Suite 312 in San Francisco's Western Addition neighborhood. Led by a team of board-certified dermatologists including Dr. Steven He and Dr. Kathleen Welsh, the practice offers a full spectrum of medical and cosmetic skin care services with a notable focus on light-based therapies — including LED facial treatments and full-body PRISM red light therapy. The practice's LED photo modulation facial uses non-thermal light-emitting diode panels to deliver specific wavelengths of red and near-infrared light to the skin. The treatment is entirely non-invasive — no heat, no downtime, and no discomfort — making it accessible for patients who cannot tolerate more aggressive resurfacing procedures. Clinical trial data cited by the practice shows improvements in skin texture, discoloration, redness, and periorbital fine lines in the majority of treated patients, with biopsies confirming improved collagen production in treated tissue. For full-body applications, Bay Area Dermatology offers the PRISM Light Pad — a professional-grade device delivering red and near-infrared light from neck to toe. The Prism platform is used for whole-body rejuvenation, post-procedure recovery acceleration, inflammation reduction, and collagen stimulation in areas beyond the face. This makes it particularly relevant for patients managing joint pain, skin laxity, or recovery from body-area procedures. With over 677 Google reviews and additional presence across Yelp, RealSelf, and Facebook, the practice has established strong credibility in the San Francisco medical aesthetics community. Sessions are appointment-based, and the team offers consultation to help patients determine the right light therapy protocol for their skin goals.
