Colleagues ask if you’re tired. In meetings, people think you’re annoyed when you’re only listening. In photos, the lines between your brows and across your forehead make you look older and sterner than you feel.
Men make up around one in ten of the people I treat for lines, and their goals are usually very clear. They want to look rested, sharp and like themselves. Nobody should be able to tell they’ve had anything done. I’ve been giving anti-wrinkle injections since 1998, and here’s how I approach treatment for men.

Why men come to see me
The most common reason is work. Men tell me they want to look energetic and approachable, not tired or stern, in a job where how you come across matters. The next most common is a nudge from a partner, who sometimes books the first appointment. Others want to feel more confident socially or when dating, or simply want the face in the mirror to match how they feel.
Whatever the reason, the worries are usually the same: looking “done”, people finding out, time off work, and whether the doctor understands what a man’s face needs.
Why men need a different approach
A man’s face isn’t a woman’s face with more lines. Treating it the same way is one of the most common reasons men are unhappy with their result.
- Men’s frowning and forehead muscles are usually larger and stronger. A plan designed for a woman often under-treats a man, and the result wears off quickly.
- Men’s skin is thicker, with less fat beneath it, so creases tend to look deeper and sharper.
- A man’s brow sits lower and straighter, over a more prominent brow bone.
- Men tend to bruise a little more easily, and a beard line affects where bruising shows.
That’s why I assess every man on his own face, not on a standard template
.
Keeping a masculine look
The overdone look in men usually comes from two things: a forehead that doesn’t move at all, and brows lifted into an arch. An arched brow looks feminine on a man and is one of the clearest signs that something has been done.
I aim to soften the lines while keeping the brow straight, strong and where it naturally sits. I leave some movement, so your face still looks expressive in conversation. The result should look like you on a good day, a better version of yourself rather than a different person.
Areas I treat in men
Most men ask about one or more of these:
- frown lines between the eyebrows, which make you look stern or angry
- forehead lines, which need careful treatment so the brows don’t feel heavy
- crow’s feet at the corners of the eyes
I also treat excessive sweating, which is common in men and can be just as much of a confidence problem as lines.
I treat the jaw muscle less often in men than in women. It can help with clenching and grinding, but most men want a broad, strong jaw rather than a slimmer one. If anything, men more often ask me to strengthen the jaw and chin.
Filler for men
Anti-wrinkle injections soften lines caused by movement. They don’t replace volume or change shape. For men, the most popular filler treatments are building a stronger jawline and a more defined chin. Filler can also help deep lines at rest, hollows under the eyes and flattened cheeks.
The principle is the same as with anti-wrinkle injections: enhance masculine features, never soften them. My page on masculine treatments for men explains more.
Privacy and discretion
Many men tell me they don’t want anyone to know they’ve had treatment. I understand that, and the clinic is set up for it.
- I see one patient at a time. You arrive, the door closes behind you, and you’re the only client in the building.
- Appointment reminders and receipts go only to your own email or phone, and the wording is neutral rather than naming a treatment.
- There’s no downtime, so you can go straight back to work, and a careful result won’t draw questions.
Your appointment
Allow about 30 minutes. I go through your medical history, ask what bothers you, and watch your face at rest and as you move it. Then we agree the plan. If you’re suitable, I usually treat you at the same visit. The injections take a few minutes, and most men describe them as a few quick pinpricks.
Afterwards, avoid strenuous exercise, the gym, saunas and rubbing the area for 24 to 48 hours. You can go back to work straight away.
I see you again at three weeks. If an area needs a little more, I top it up then, and that’s included in your treatment.
How long results last
In men, the result usually lasts three to four months. Stronger muscles tend to wear it off a little sooner than in women. With regular treatment, the effect often lasts longer, and most men find a rhythm that suits them after the first year.
Side effects and risks
The common side effects are small: tiny marks at the injection points for an hour or so, and occasionally a bruise or a mild headache. Rarely, a brow can feel heavy or an eyelid can droop for a few weeks, which is why I assess your brows and eyelids carefully before treating the forehead. These effects are temporary, and if one happens I’ll see you and help.
Cost
The cost depends on which areas you’d like treated, so I’ll confirm it at your consultation. Your 3-week review, and a top-up if needed, are included. You’ll find our current prices on the cosmetic injection price list.
Anti-wrinkle injections for men FAQs
Will people be able to tell I’ve had something done?
Not if it’s done well. I aim for a rested, natural look that keeps your brow straight and your face expressive. Most people notice you look well, not that you’ve had treatment.
Are men treated differently from women?
Yes. Men usually have stronger muscles, thicker skin and a lower, straighter brow, so the plan is different. Treating a man like a woman often gives a short-lived or feminine-looking result.
How long do anti-wrinkle injections last in men?
Usually three to four months. With regular treatment, the effect often lasts longer.
Is there any downtime?
No. You may have small marks for an hour or so. You can go back to work the same day, but avoid the gym for a day or two.
What age should men start?
There’s no set age. I treat lines that bother you, not birthdays. If you have no lines yet, you don’t need treatment.
Do you treat many men?
Yes. Men make up around one in ten of the people I treat for lines, and I’ve been giving anti-wrinkle injections since 1998.
Can I have filler as well?
Yes. Many men combine anti-wrinkle injections with filler to strengthen the jaw or chin. I’ll tell you honestly whether it would help.
Do you show before and after photos?
Because anti-wrinkle injections are a prescription-only medicine, I don’t publish before and after photos of them. At your consultation, I’ll explain what result to expect.
If you’d like to look as sharp as you feel, book a consultation at our clinic in Castleknock, Dublin 15. I’ll look at your face, tell you honestly what will help, and keep it discreet.
