When men talk about forehead wrinkles, the conversation almost always covers two patterns: horizontal lines (the ones running across the forehead from temples) and the '11s' (the vertical frown lines between the brows). But there's a third pattern that's common in men and rarely discussed: vertical lines running up-and-down on the forehead itself. These behave differently, are caused by different muscle actions, and require a different treatment approach. If you have vertical forehead lines and are wondering why standard Botox advice doesn't quite fit, this article is for you.
Quick Answer: Vertical forehead lines in men are usually caused by the corrugator and procerus muscles pulling the forehead skin inward and upward in tension patterns distinct from horizontal lines. They're treatable with Botox, but require injector experience with this specific pattern — the muscle targets are different from those used for horizontal lines.
Horizontal vs. Vertical Forehead Lines: What's the Difference?
Horizontal forehead lines — the classic kind — are caused by the frontalis muscle, which runs vertically on both sides of the forehead and contracts when you raise your eyebrows. The muscle fibers run vertically, so their repeated contraction creates horizontal lines perpendicular to their direction. Vertical lines on the forehead, by contrast, are typically caused by muscle actions that pull the forehead horizontally or in diagonal tension — often a combination of the corrugators (which pull the brows inward), the procerus (which pulls the brow bridge down), and other muscles of upper facial expression that work in concert. Men with pronounced vertical forehead lines often have a distinctive 'intensity look' — deep concentration lines that remain visible even when the face is at rest.

Men's frontalis and corrugator muscles are typically larger and stronger than women's, and men's facial skin is thicker, which means more forceful muscle contraction is required to overcome the skin's resistance before lines form — but once they do, they tend to be deeper. Men who concentrate intensely at work (programmers, surgeons, traders, writers), men who spend time outdoors squinting, and men who clench or tense during high-stress situations are particularly prone to developing prominent vertical forehead patterns. Men with naturally expressive upper faces or pronounced brow ridges sometimes develop these lines earlier than peers.
Are These Treatable with Botox?
Yes — but the injection map needs to target the specific muscles creating your vertical pattern, which may be different from the standard treatment for horizontal lines. Standard forehead Botox (targeting the frontalis for horizontal lines) may not be the primary approach for vertical lines. An experienced injector will assess which muscles are most responsible for your specific pattern — often the corrugators, procerus, and possibly the temporal muscles — and design a treatment plan accordingly. This is why a consultation with someone experienced in advanced facial anatomy matters more for this presentation than for straightforward horizontal forehead lines.

Common vertical and diagonal forehead line patterns in men and their likely muscle origins:
- •Central vertical lines running straight up from the nose bridge: Typically corrugator and procerus muscle involvement. These connect to the '11s' pattern and respond well to standard glabellar Botox.
- •Diagonal forehead lines running from inner brow upward and outward: Often a combination of corrugator and frontalis. These require a more customized injection pattern to relax the diagonal pull.
- •Multiple short vertical lines above the horizontal lines: Can indicate a tension pattern from the temporal and frontalis muscles working together. May need additional injection points beyond standard placements.
- •A single prominent vertical crease in the center of the forehead: Often caused by habitual furrowing during concentration. Responds well to targeted Botox but may require filler if already deeply static.
When Botox Alone Isn't Enough
If your vertical forehead lines are deeply etched — static at rest with a clear groove in the skin — Botox alone will relax the muscle causing continued deepening, but won't fully erase the groove already formed. Deeply static vertical lines often benefit from a combination approach: Botox to stop further progression, followed (weeks later, not simultaneously) by hyaluronic acid filler placed along the crease to fill in the groove. This is a specialized injection requiring significant injector skill — the forehead is an unforgiving area for filler technique. Discuss combination options with your provider.

What to Tell Your Injector
Be specific: 'I have vertical lines on my forehead' and demonstrate the facial movements that create or deepen them. Show photos of yourself concentrating, squinting, or in work mode — the expressions that activate the pattern most. Ask your injector to explain which muscles they're targeting and why. A provider who gives you a generic horizontal-forehead treatment protocol without discussing your specific vertical pattern isn't engaging with your actual concern. The best results come from customized mapping based on your individual facial anatomy.
