How Much Does Botox Cost in Renton, WA? A Transparent Price Guide

Here's the straight answer: at Flawless Aesthetics in Renton, Botox is $11 per unit. A typical first-time upper-face treatment lands between $220 and $440, depending on how many areas you're treating and your muscle strength. There are no membership fees, no hidden line items, and no pressure to come back every eight weeks.

How Botox pricing works

Botox is priced per unit, not per syringe or per area. A "unit" is a standardized dose of onabotulinumtoxinA — the same measurement every reputable injector uses. The price per unit varies by clinic, but the number of units for each area is fairly consistent across the industry.

This is important because you'll sometimes see ads for "$199 Botox special" that don't actually disclose how many units you're getting. A clinic charging $15 per unit for 15 units ($225) is giving you less product than a clinic charging $11 per unit for 25 units ($275) — even though the second visit costs more. Price per unit is the only fair comparison.

At Flawless Aesthetics, Helen Petrov, BSN, RN charges a flat $11 per unit. Whether you need 8 units or 50, the per-unit rate is the same, and you'll know the exact total before anything is injected.

How many units do you need?

Unit counts vary based on your muscle strength, the area being treated, and whether you're a first-time or returning patient. First-timers often need a few more units because their muscles haven't been calmed yet. Here are the typical ranges Helen uses:

Most first-time patients come in for a combination of two or three upper-face areas — forehead, frown lines, and crow's feet — which lands in the $250–$450 range. Someone doing a small, focused area like a lip flip or a few units for bunny lines might spend under $100. It depends entirely on what you're treating.

What's included in your appointment

Every Botox visit at Flawless Aesthetics includes:

• A brief consultation and treatment planning — Helen maps the areas and confirms unit counts before anything is injected.
• Medical screening for contraindications (current medications, pregnancy, recent antibiotics, allergies).
• The injection itself, with optional topical numbing cream for sensitive patients.
• Written aftercare instructions — what to do (and avoid) for the first 24 hours.
• A complimentary 2-week follow-up for new patients to make sure everything landed evenly.

No membership. No "VIP tier." No separate fee for the consultation. The only thing you pay for is the units you actually receive.

How $11/unit compares to the Seattle area

For context, here's what per-unit pricing typically looks like in the broader Seattle / Eastside medical aesthetics market:

• Renton / South King County medspas: $11–$14 per unit (Flawless Aesthetics at $11 is the transparent floor of this range)
• Bellevue / Kirkland premium medspas: $12–$15 per unit, often with $100–$200 monthly membership fees layered on top
• Seattle / downtown chains (SkinSpirit, etc): $13–$18 per unit, premium branding
• Washington state average (CareCredit data): ~$452 per treatment

If you're coming from Bellevue, Kirkland, Redmond, or Mercer Island, the 12-minute drive to Renton saves roughly $60–$150 per visit — which adds up across the year. Same products (Allergan Botox Cosmetic), same FDA-approved treatment, different zip code.

Red flags: when Botox is suspiciously cheap

If you see Botox advertised below $9 per unit, ask questions before you book. A few things that should make you pause:

1. "$199 full face" specials without a unit count. This usually means very few units being spread thin — a weak result that needs re-treatment within six weeks.
2. Diluted or counterfeit product. Real Botox Cosmetic (Allergan) arrives in vials with holograms and a batch number your injector can verify. Deep discount clinics sometimes reconstitute with extra saline to stretch the product.
3. Non-medical settings. Botox should be administered by a qualified medical professional (MD, NP, PA, or RN under physician delegation) in a clinical setting — not a salon or spa back room.
4. No medical screening. A reputable clinic will ask about pregnancy, medications, allergies, and neuromuscular conditions before injecting. If they skip this, that's a safety problem.

How often will I need to come back?

Botox typically lasts 3–5 months. First-time patients often see a shorter duration (2–3 months) because their muscles are stronger and haven't been calmed yet. Returning patients usually stretch further because the treated muscles gradually stay more relaxed with consistent treatment.

Most of Helen's regular patients come in every 3–4 months. That works out to 3–4 visits per year, or roughly $800–$1,400 annually for ongoing maintenance of the upper face. A one-time treatment (for a wedding, a photoshoot, a specific event) is also completely reasonable — there's no requirement to commit to a schedule.

Ready to book?

Booking is straightforward. Most patients schedule directly through the Square booking link below — no consultation visit required before your first treatment. If it's your first time and you have questions, Helen also offers a free 30-minute consultation you can book separately.
