Case Study: PCOS Laser Hair Removal, Chin and Jawline, with the GentleMax Pro

Why she came to see me

By Swaleen Nissan, Lead Medical Aesthetician, 20+ years

I am Swaleen Nissan, Lead Medical Aesthetician at Distill Laser Clinic in North York. In more than 20 years in medical aesthetics, and with more than 10,000 treatments performed at our clinic, hormonal facial hair is one of the cases I see most often, and one of the cases where clients arrive most discouraged. That volume of work is part of why Distill Laser Clinic received the Consumer Choice Award 2026 for laser hair removal. This is the real story of one client. I will call her Sara, which is not her real name, to protect her privacy. She has given written consent to share her photographs and her story.

Sara has polycystic ovary syndrome, PCOS. For her, the most visible part of it was coarse, dark hair along her chin and jawline that came back within a day of shaving. She had tried plucking, threading and waxing for years. Each one left bumps and dark marks that took weeks to fade, and none of them changed how fast the hair returned. She told me she planned her week around it.

Her journey started with a free consultation at our North York clinic. No pressure, no sales pitch, just a look at her skin and her hair and an honest answer about what laser could and could not do for hair that hormones keep pushing to grow.

The consultation: what PCOS changes about the plan

Laser hair removal works by sending a pulse of light into the skin. The pigment in the hair absorbs that light; it turns into heat, and the heat disables the follicle that grows the hair. That only works well when the wavelength matches the person in the chair, so the first thing I do at every consultation is check skin type and hair colour.

Sara has Fitzpatrick type I skin, very fair, with dark coarse hair. That is the combination a laser likes best, because the light is drawn to the pigment in the hair and not the skin around it. For her skin type, I used the Alexandrite 755nm wavelength. We run two laser platforms at Distill, the Candela GentleMax Pro and the Cynosure Lutronic Clarity II, and both carry two wavelengths. For Sara, I chose the GentleMax Pro. It pairs high power with a cryogen cooling spray timed to every pulse, and that combination is my pick for dense, coarse hair.

Here is what PCOS changes. Laser disables the follicles that are growing hair today, but PCOS keeps the hormone signal on, and that signal can wake follicles that were resting. So I plan for more sessions than a client without PCOS, 8 to 12 instead of 6 to 8, and I tell every PCOS client at the first visit that a maintenance session once or twice a year is part of the plan, not a sign that something failed. Laser manages the hair. It does not treat PCOS, and I said so plainly.

I also went through her medical history and current medications, and I asked about recent sun exposure and self-tanner. A fresh tan raises pigment in the skin and increases burn risk, so we do not treat it. Sara was clear on everything, and we booked her first session.

Her treatment plan: 8 sessions, 4 weeks apart

Laser only works on hair that is in its active growth phase and still attached to its follicle. Only a share of your hair is in that phase at any one time, which is why laser hair removal is a course of sessions rather than a single visit.

For the face, I space sessions 4 to 6 weeks apart, closer together than the body, because facial hair cycles faster. With PCOS driving the growth, I keep the spacing tight and the course longer. Sara needed 8 sessions, 4 weeks apart.

Before every session, she followed the same routine:

• Shave 24 hours before. The laser needs the hair in the follicle, not on the surface. Long hair above the skin burns and stings.
• No waxing, plucking, threading or epilating for 4 weeks. Those methods pull the hair out by the root, so the laser has nothing to target. For Sara, this was the hardest rule, and the most important one.
• No sun or self-tanner for 2 weeks. Tanned skin carries more pigment and pulls energy away from the hair.
• Clean skin on the day. No makeup, lotion or perfume on the chin and jaw before treatment.

What the sessions felt like

The chin and jawline are small areas, so each visit was quick. I cleansed the skin, set the wavelength and settings for her skin type and coarse hair, and worked along the jaw in even passes so no spot was missed.

I will be honest, because this is the question people ask quietly. Laser hair removal always involves some sensation. Sara described each pulse as a warm snap, like an elastic band against the skin, sharper on the chin where the hair was thickest. The GentleMax Pro sprays a short burst of cryogen onto the skin just before each pulse, which protects the surface and takes the edge off almost at once. She found the sessions generally well tolerated, and like most clients, each one got easier as the hair thinned.

After each session, her chin was a little red, like a light sunburn, and that settled within a few hours. For the first 24 to 48 hours, she avoided heat, hard workouts, and sun on the area, then went back to her normal day.

Shedding, and why it looks like regrowth

This is the part that worries people, and it is worth understanding before you start. Over the one to three weeks after a session, the treated hairs loosen and slide out of the follicle. It can look like the hair is growing back. It is not. Those hairs are already dead and on their way out.

I told Sara to let them fall out on their own and never to pluck them, which, for a PCOS client who has plucked for years, takes real discipline. Shaving between sessions is fine. Once she understood what was happening, the shedding stopped worrying her and became the sign that the session had worked.

Her results

Sara came back for every session on schedule, 4 weeks apart, for 8 sessions in total. After the first three, the hair that returned was finer and sparser, and she was shaving every few days instead of every day. With no more plucking, the bumps and dark marks along her jaw began to fade. By the time we took her final photographs, the difference was clear. Far less hair remained, what was left was fine and light, and the skin along her jawline was smooth and even.

I want to be careful with my words here, because a lot of clinics are not, and with PCOS it matters more. Laser gives you long-term hair reduction, not lifelong hair removal. Hormones can wake new follicles, so Sara books a maintenance session once or twice a year, and that keeps her where the after photograph shows. If a clinic promises a PCOS client smooth skin forever, that is a sales line, not a clinical fact.

This is the outcome we work toward on every hormonal hair plan at our clinic for laser hair removal in North York. You can read how we build these plans on our laser hair removal for PCOS page, and about the laser itself on our Candela GentleMax Pro page.

What I tell clients with PCOS

Put the tweezers away. Plucking and waxing remove the hair the laser needs to find, and they make the bumps and dark marks worse. Shave instead, and shave the day before each session.

Expect a longer course and plan for maintenance. That is not the laser failing; that is PCOS doing what PCOS does. Managing the condition with your doctor also helps your laser results last longer.

And ask questions. If you are not sure whether laser suits your skin or your hair, a free consultation at our North York clinic will give you a straight answer. Ask about a patch test at your consultation.
