One of the most common frustrations men have with Botox is paying for a treatment that barely made a difference. The culprit is almost always under-dosing. Male facial muscles — especially the frontalis (forehead), corrugators (frown lines), and masseter (jaw) — are substantially larger and more powerful than their female counterparts. A dosing protocol designed for a 120-pound woman will produce a noticeably weaker result in a 185-pound man with heavy facial musculature. Understanding the unit ranges for each area means you can verify your provider is treating you appropriately, not economizing on product at the cost of your results.
Why Men Need More Units Than Women
Botox works by blocking nerve signals to the muscle. The amount of Botox needed to achieve adequate muscle relaxation scales with the size and strength of the muscle being treated. Male facial muscles average 30–40% more mass than female facial muscles, and men who exercise regularly, clench their jaw, or furrow their brow habitually often have even more developed musculature. Providers who primarily treat women and haven't adjusted their male dosing protocols will routinely under-dose male patients. The product cost difference between treating a man correctly and treating him with a women's dose is usually $30–80 — minimal in the context of a $400–700 treatment, but providers who bill per unit rather than per area sometimes under-dose to manage product cost. Know the numbers going in.
Forehead: 15–30 Units

Search by Zip Code →The forehead (frontalis muscle) is the most commonly treated area in men. Women typically need 10–15 units; men need 15–30 units, with the higher end appropriate for men with heavily expressive foreheads or large muscle mass. The frontalis is also the trickiest area in men because it's the primary elevator of the brow — over-treating the forehead without balancing the brow depressors (the frown line muscles) can cause brow ptosis, where the brow drops and creates a heavy, hooded appearance. Experienced providers use conservative forehead dosing combined with treatment of the glabella to maintain brow position.
Frown Lines (Glabella): 20–30 Units
The glabellar complex — the corrugator supercilii and procerus muscles responsible for the '11 lines' between the brows — is typically the highest-priority treatment area for men. These muscles create the angry, fatigued expression that men most often want addressed. Women need 15–25 units; men typically need 20–30 units, with some men with heavy brow muscles benefiting from 30–35 units. Under-dosing the glabella is the single most common dosing error in male Botox. The result is a partial softening of the 11s that looks incomplete rather than refreshed.
The most common dosing mistake in men: treating the forehead with a female dose (10–15 units) when the male therapeutic dose is 20–30 units. If your last treatment barely made a difference, under-dosing is the first place to investigate. Show your provider this guide and ask specifically about male dosing protocols.

The orbicularis oculi — the muscle that creates the web of lines at the outer corners of the eyes — responds well to Botox in both sexes. Men typically need 6–12 units per side (12–24 total), versus women's 8–12 total. The difference is less dramatic here than in the forehead and glabella, because the periorbital muscles are smaller relative to other male facial muscles. Over-treating crow's feet can flatten the lateral eye in a way that looks unnatural, so your provider should err slightly conservative and adjust at touch-up.
Jawline / Masseter: 25–50 Units Per Side (50–100 Total)
Masseter Botox (jaw slimming / TMJ treatment) requires the most units of any facial area and shows the greatest sex difference in dosing. Women need 20–35 units per side; men often need 30–50 units per side, with some men who are heavy grinders or have especially developed masseter muscles needing the full 50 units per side. This is a high-unit, high-cost treatment area ($500–1,500+ per session) but also one of the most dramatic for men who carry excess jaw bulk or grind their teeth. Full results take 4–8 weeks as the muscle atrophies.

Additional male dosing reference ranges:
- •Brow lift (tail of brow elevation): 4–8 units
- •Bunny lines (sides of nose): 4–8 units
- •Lip flip (upper lip): 4–8 units
- •Chin dimpling (mentalis): 6–10 units
- •Neck bands (platysma): 20–60 units total depending on bands
- •Underarm sweating (hyperhidrosis): 50 units per underarm
- •Forehead hairline (sweat): 50–100 units total across the zone
Getting the dosing right matters more than most men realize. A properly dosed treatment at a slightly higher cost produces results that last 3–4 months and justify the expense. An under-dosed treatment that fades in 6–8 weeks is not good value at any price. When evaluating providers, ask directly: 'What is your typical dosing protocol for men in this area?' A provider who quotes you the same unit range they use for women without adjustment is a red flag. Find male-focused providers with appropriate dosing protocols at /find-botox-near-me.
