For 1 week before: avoid blood-thinning supplements (vitamin E, fish oil, gingko, garlic supplements) and over-the-counter NSAIDs (Advil, Motrin, aspirin) unless medically necessary. These increase bruising risk. Avoid alcohol for 24 hours prior. Arrive with clean, makeup-free skin if possible. Eat beforehand to avoid lightheadedness. Plan to avoid laying flat for 4 hours after Botox.

Botox (also known as Neurotoxin, Botulinum toxin) is one of several options in this treatment category. The main differences vs. alternatives are formulation, onset time, duration, and pricing. Your San Mateo provider can recommend the best fit for your specific goals during consultation.

Botox is a purified protein (botulinum toxin type A) that temporarily blocks the nerve signals telling specific muscles to contract. Injected in tiny doses into targeted facial muscles, it relaxes them just enough to smooth dynamic wrinkles: the lines that appear when you frown, raise your eyebrows, or smile. It doesn't add volume; it doesn't change your face shape. Within 2 weeks, the treated area looks smoother at rest. Effects last 3–4 months, then the muscle gradually regains movement.

The most common real risk is unintended muscle weakness near the injection site, typically a temporary drooping eyelid (ptosis) or asymmetric brow if the toxin migrates slightly from where it was injected. This is almost always tied to either improper injection technique or excessive rubbing/laying down too soon after treatment, and it resolves on its own in 4–8 weeks as the Botox wears off. Serious systemic side effects are extremely rare at cosmetic doses. Choosing an experienced injector is the single biggest factor in avoiding all of these.

The "4-hour rule" means don't lay flat, exercise vigorously, or massage the treated area for the first 4 hours after your Botox appointment. The concern is that lying down, intense head movement, or rubbing the area could allow the Botox to migrate from the intended muscle to nearby muscles, potentially causing a droopy eyelid or asymmetric result. Most providers also recommend avoiding heat (saunas, hot yoga) and alcohol for 24 hours. After 4 hours, you can resume normal activity. Some providers extend this to 6 hours for extra caution.

At the US average of $10–$20 per unit, 20 units of Botox typically costs $200–$400. Twenty units is a common dose for treating the glabella (the "11s" frown lines between your brows) or for a light forehead treatment. A more complete full-face treatment usually uses 40–70 units, putting most appointments in the $400–$1,400 range. Pricing varies meaningfully by city and provider experience: premium markets and senior injectors charge at the upper end.

There's no universal "right" age: it depends on when your dynamic wrinkles start bothering you, not what's on your driver's license. Most providers see people start in their late 20s or early 30s for "preventative Botox," which uses small doses to soften lines before they become etched. Starting later (40s, 50s, 60s) is equally valid; you'll just be treating existing wrinkles rather than preventing new ones. There's no medical benefit to starting young if your skin isn't showing dynamic lines yet. Wait until you actually want the result.

Yes, for most patients. After 60, Botox can still meaningfully soften dynamic forehead and frown lines and crow's feet. It won't address loose skin, lost volume, or the deeper static wrinkles that have set in at rest. Those typically need fillers, skin tightening, or surgery in combination. Many older patients get the best results from a combination plan: smaller Botox doses to soften muscle activity, plus fillers or skin tightening for volume and laxity. Discuss realistic expectations with your provider during consultation.

Yes, Botox is technically a neurotoxin, derived from the bacterium Clostridium botulinum. But the cosmetic dose is incredibly small (a fraction of a microgram), purified, and used in localized injections. It has been FDA-approved for cosmetic use since 2002 and is one of the most studied injectables in medicine, with decades of safety data across millions of treatments. Safety depends heavily on injector skill: choose a board-certified physician, PA, NP, or RN with extensive injection experience for the lowest risk of complications.

Different problems, different products. Botox relaxes muscles to soften wrinkles caused by movement (forehead lines, frown lines, crow's feet). Fillers add volume to areas that have lost it (cheeks, lips, smile lines, jawline). They're commonly used together (Botox for the upper face, fillers for the lower face) for a balanced refresh. Botox lasts 3–4 months; fillers last 9–18 months. Per treatment, fillers cost more upfront but last longer.
