Botox Injections
Smoother Younger Complexion
Natural-looking results administered by Dr. Tanya Zamorano, Board Certified Family Physician. Zero downtime, transparent pricing, and same-day consultations available in Mill Valley CA and Marin County.
Want to look more refreshed? Reduce the appearance of fine lines and wrinkles? Botulinum toxin type A (aka Botox, wrinkle relaxers) are injectable neurotoxins that temporarily block nerve impulses to the muscles, causing them to relax. The result? A softer, smoother, younger-looking complexion with zero downtime.
What is Botox
Botox injections explained
Botulinum toxin type A is most widely known by the brand name Botox® and is an FDA-approved injectable that temporarily relaxes targeted facial muscles. By reducing the repetitive contractions that cause fine lines, forehead wrinkles, frown lines, and crow's feet, Botox creates a smoother, more refreshed appearance with absolutely zero downtime.
At Glow Health Medical Clinic in Mill Valley, every Botox treatment is performed personally by Dr. Tanya Zamorano, a Board Certified Family Physician with specialized expertise in aesthetic medicine. Unlike med spas where injections are delegated to nurses or technicians, your care here is true physician-grade, meaning more anatomical precision, better safety oversight, and results that look genuinely natural.
Results begin to appear within 5–7 days, reach their peak around two weeks post-treatment, and typically last 3–6 months. With consistent maintenance, many patients find they need fewer units over time as treated muscles naturally weaken from reduced use which is a long-term benefit few patients anticipate.

When Should You Start?
Preventative Botox by age
"Baby Botox" and preventative treatments have become one of the most searched aesthetic topics. Here's how the approach changes across decades and why starting earlier than you think often makes sense.
There is no single "right" age to start. Dr. Zamorano will assess your goals to recommend the right timing for you. There is never a one-size-fits-all approach.
20s
Prevention
Dynamic lines are just forming. Small doses in problem areas prevent creases from becoming permanent. "Baby Botox" uses fewer units for ultra-natural results. Common areas: forehead, glabellar.
30s
Early Treatment
Lines are becoming visible at rest. Botox softens existing creases and stops new ones from deepening. This is the most popular decade to start. Most patients treat 2–3 areas.
40s
Maintenance
Lines are more established. Botox remains highly effective and is often combined with fillers for volume loss. Many patients see the biggest visible improvement when starting in this decade.
50s+
Refinement
Botox continues to work beautifully as part of a broader plan. Often paired with dermal fillers, skin treatments, or HRT for comprehensive rejuvenation addressing both movement and volume.

Enhance Your Results
Pair Botox with other treatments
Botox addresses muscle-driven lines — but it works even better as part of a broader aesthetic plan. These are the most popular combinations our Marin County patients request.
Most Popular
Botox + Derma Fillers
The "liquid facelift." Botox relaxes dynamic wrinkles while fillers restore lost volume in the cheeks, lips, and under-eyes. Together they address both movement and structure for a comprehensively refreshed look without surgery.
skin Quality
Botox + Microneedling
Botox handles muscle-driven wrinkles while microneedling stimulates collagen to improve skin texture, pore size, and radiance. A favorite combination for patients wanting both smoothness and glow.
Hormonal Aging
Botox + Hormone Therapy
Hormonal changes — especially in perimenopause and menopause — accelerate collagen loss and skin thinning. Combining Botox with HRT addresses both the surface and the systemic factors driving visible aging. Dr. Zamorano manages both.
