Laser Hair Removal and Hidradenitis Suppurativa

Laser hair removal is sometimes used as an add-on treatment for hidradenitis suppurativa, because the condition starts in hair follicles and reducing those follicles may mean fewer flares in some people. It is not a cure and does not replace medical care. The evidence is encouraging but still limited, and it works best for milder disease, between flares, as part of a plan led by your family doctor or dermatologist.

What hidradenitis suppurativa is

Hidradenitis suppurativa, often shortened to HS, is a long-term inflammatory skin condition. It causes painful lumps, boils and abscesses in areas where skin rubs together and hair grows, such as the underarms, groin, inner thighs, buttocks and under the breasts. Over time, repeated inflammation can create tunnels under the skin and scarring.

HS is not caused by poor hygiene and it is not contagious. It is thought to begin when hair follicles become blocked and then rupture, triggering inflammation. Genetics, hormones, the immune system, smoking and excess weight can all play a part. Many people live with it for years before getting a diagnosis, and it can affect sleep, work, relationships and mood. If you recognise these symptoms, the first step is to see your family doctor.

Why hair follicles matter

Because the problem begins in the follicle, researchers have looked at whether destroying follicles in affected areas could reduce flares. Laser hair removal targets the pigment in the hair shaft and root, and the heat damages the follicle so it produces less hair, or finer hair, afterwards.

Small studies, mostly using long-pulse Nd:YAG lasers, have reported fewer or milder flares in treated areas for some people with mild to moderate HS. These studies have been modest in size, and results have varied. What is reasonably established is that it can be a helpful supporting option for selected people. What is not established is how long any benefit lasts, which patients will respond, or whether it helps advanced disease with deep tunnels and scarring.

Working alongside your medical care

HS is managed medically first. Depending on severity, your doctor or dermatologist may suggest antiseptic washes, topical or oral antibiotics, hormonal treatments, newer biologic medicines, or surgery for persistent areas. Lifestyle support, such as help with stopping smoking and managing weight where relevant, is often part of the plan too.

Laser hair reduction, if appropriate, sits beside these treatments rather than replacing them. Before any laser, it helps to:

• Have a confirmed diagnosis and an understanding of how severe your HS is.
• Let your dermatologist or family doctor know you are considering laser, so care can be coordinated.
• Bring a full list of medications. Some antibiotics and other medicines make skin more sensitive to light. Do not stop or change any prescription on your own; your physician can advise.

If you are on a biologic or other immune-modifying medicine, your treating physician should be part of the decision.

Timing treatment around flares

Laser is generally done on skin that is calm, not during an active flare. Treating inflamed, open or draining areas can be painful, may worsen inflammation and raises the risk of infection. If a flare starts close to an appointment, the session is usually postponed or the active spots are avoided.

Like ordinary hair removal, treatment is done as a series because only actively growing hairs respond at any one time. Many people need several sessions spaced several weeks apart, with occasional maintenance later. See how many laser hair removal sessions you may need for more on hair growth cycles.

Before each visit you will usually be asked to shave the area, not wax or pluck, since the follicle needs to be present for the laser to target it. Waxing and plucking can also irritate HS-prone skin.

Who may not be suited, or should wait

Laser hair reduction is less likely to help, or may need to wait, if you:

• Have severe disease with extensive tunnels or scarring, where medical or surgical treatment is the priority.
• Have an active flare, open wound or infection in the area.
• Have very light, grey or red hair, which has too little pigment for the laser to target.
• Are pregnant, in which case elective laser is usually postponed.
• Have a recent tan, sunburn or use of medicines that increase light sensitivity.
• Have a history of keloid scarring, which calls for extra caution.

Risks and what it may feel like

Laser hair removal feels like quick snaps or heat against the skin. HS-affected areas can be tender, so comfort measures such as cooling are used. Common short-term effects include redness, swelling and bumps around follicles for a day or two.

Less common risks include blistering, burns, temporary darkening or lightening of the skin and, rarely, scarring. Deeper skin tones have a higher risk of pigment change, which is one reason Nd:YAG settings are often used. Some people notice a short-lived flare-up of inflammation after a session. Report any spreading redness, pus or fever promptly.

Realistic expectations

For people who do respond, the hoped-for change is fewer or less intense flares in the treated area over time, not the disappearance of HS. Untreated areas can still flare, and existing scars and tunnels will not be removed by laser hair reduction. Results vary from person to person, and some people notice little difference.

It is reasonable to agree on what you will watch for, such as flare frequency or pain, so you and your doctors can judge whether it is worth continuing.

Frequently asked questions

Is laser hair removal a recognised HS treatment?

Some dermatology guidance mentions it as a possible supportive option for milder disease, but it is not a first-line or stand-alone treatment, and the research base is small.

Will it hurt more than regular laser hair removal?

It can be more uncomfortable on tender or scarred skin. Treating only calm skin and using cooling usually helps.

Can I keep using my prescribed washes and creams?

Usually yes, though some may need a short pause around sessions. Your provider will check with you and, where needed, your prescriber.

How will I know if it is working?

Keeping a simple log of flares before and during the series helps you and your doctor compare honestly.

If you live with HS and want to know whether laser hair reduction might fit alongside your current care, HealthPark Medical Aesthetics can discuss it with you and, with your permission, coordinate with your family doctor or dermatologist. For some people, focusing on medical treatment first is the more helpful path.
