Women-owned holistic skincare studio Simply Skin brings DermaSound Ultrasonic facial technology to downtown San Diego's Little Italy at 619½ West Fir Street. The DermaSound system uses low-frequency sound waves at 28 kHz for cavitation-based exfoliation and sonophoresis-driven serum infusion, penetrating active ingredients up to 10,000 times deeper than manual application — a sonic approach to barrier repair that complements the holistic health modalities at Saffron & Sage in Bankers Hill. Face Reality Acne Specialist certification guides a mandelic-and-salicylic acid protocol that clears comedonal and inflammatory acne within three to six months through bi-weekly clinical treatments and home-care product sequencing. Intraceuticals Oxygen Infusion facials deliver hyaluronic acid under hyperbaric oxygen pressure for immediate hydration plumping, a red-carpet prep treatment that sits on the same wellness corridor as the infrared sauna sessions at HOT HAVEN - Sauna Studio. Jet Plasma Skin Therapy applies nitrogen-based cold plasma at sub-thermal temperatures to tighten lax tissue and reduce active acne lesions without ablation or downtime.
