About The G Spa San Francisco
The G Spa San Francisco is a boutique medical spa situated in the heart of Union Square, steps from Saks Fifth Avenue at 460 Post Street. Blending clinical precision with a refined day-spa atmosphere, The G Spa offers a curated menu of aesthetic and wellness treatments overseen by Dr. Grenier and a team of skilled nurses and licensed aestheticians. Their LED Light Therapy program stands out as one of the more accessible and thoroughly delivered offerings in the city. LED light therapy sessions at The G Spa use panels that cycle through blue, red, and near-infrared wavelengths over a 15-to-30-minute treatment. The blue light targets acne-causing bacteria, while red and near-infrared wavelengths penetrate more deeply into the dermis to stimulate collagen production, reduce inflammation, increase circulation, accelerate tissue repair, and improve overall skin tone and texture. LED sessions can be booked as standalone appointments or added on to virtually any other treatment for enhanced cellular repair. Beyond LED therapy, The G Spa provides CO2 laser facials, AviClear acne laser treatments, injectables including Botox and dermal fillers, and a variety of skin-rejuvenating facials. The Union Square location makes it easy to combine a treatment with other downtown activities. Dr. Grenier and Nurse Shannyn are frequently cited for their thoroughness in consultations, taking time to walk clients through expected outcomes and aftercare. The spa maintains a 4.6-star average across review platforms, reflecting consistent satisfaction across its treatment menu.
