Fotona Laser Treatment for Cystic Acne

[post_date] [post_comments] [post_edit]

Cystic acne is the most severe form of acne and the most prone to scarring. Unlike papular or acne, the cysts deep beneath the skin — large, painful, inflamed nodules filled with pus that can persist for weeks and are slow to settle. The combination of deep and slow healing is exactly what drives the characteristic atrophic that follows untreated cystic acne.

acne treatments often on cystic disease. Topical actives can’t reach the depth where the cysts sit. Oral help with but don’t fully the underlying mechanism. Isotretinoin works but carries significant side and . For many patients, represents the most effective intervention for cystic acne — the disease at the depth where it lives without the exposure of .

This guide how cystic acne develops, why Fotona laser is particularly suited to treating it, what a course looks like, and how the approach with the other at our Baker Street private hospital.

What cystic acne is

Cystic acne is characterised by large, painful, inflamed lesions sitting deep in the dermis. The cysts are pus-filled, often 5 mm or more in diameter, and last several weeks before resolving. Most commonly the face is affected — particularly the jawline, chin and cheeks — but cystic acne also on the chest, back, upper arms and shoulders.

Several features cystic acne from other forms:

The pattern is often with severe nodular acne or with severe folliculitis, and the distinction because management differs. A thorough clinical at establishes which pattern you have and what’s driving it.

What drives cystic acne

The shares the four core of all acne — excess sebum production, abnormal shedding blocking pores, colonisation by Cutibacterium acnes bacteria, and — but with several that push it into the cystic .

Hormonal cycling drives cystic acne more than other forms. Premenstrual flares, onset, postpartum changes and androgen excess all commonly present as cystic . The jawline-and-chin distribution typical of hormonal acne is also the most common location for cysts.

Family of cystic acne is a strong predictor. The inherited tendency affects sebaceous gland sensitivity to hormones, follicular and .

The cystic develops when the inflammatory is intense enough to the follicular wall, contents into the dermis and triggering a much larger cascade. Once this rupture-and-cascade is established, it tends to repeat.

Manual manipulation of drives the deep tissue damage that converts a surface pustule into a true cyst. This is the single most preventable cause of cystic conversion and of the scarring that follows. Don’t acne lesions, particularly inflamed ones.

Pressure (helmets, masks, leaning on the face), occlusion (heavy comedogenic products), heat and humidity, stress, certain (corticosteroids, lithium, some hormonal therapies), and diet can all contribute to flares.

Why Fotona Nd:YAG laser suits cystic acne

The Fotona SP Dynamis Pro at our clinic uses Nd:YAG laser at 1,064 nm — a wavelength specifically suited to addressing the depth at which cystic acne lives. Four mechanisms work in parallel:

1,064 nm through the without ablating the surface, reaching directly to the glands and deep follicular where cysts . Topical treatments simply cannot reach this depth. Oral medications work systemically but distribute throughout the body. The Nd:YAG laser effect exactly where it’s needed.

Sebum is the foundational driver of cystic acne — without excess sebum, follicles don’t block, don’t colonise, and the inflammatory cascade doesn’t begin. The photothermal effect on glands their size and activity, addressing the disease at the source. This mechanism is similar to isotretinoin’s action but locally rather than .

The heat generated by the laser kills Cutibacterium acnes bacteria in the follicle. Unlike oral antibiotics, which drive resistance, the laser doesn’t select for resistant . This is both a clinical advantage for the patient and a public-health .

Laser energy in the skin, reducing the size and pain of active cysts. The same thermal effect stimulates in the deeper dermis, producing new collagen that begins early while active is still being . This dual effect is unique to laser among acne treatments.

The treatment course for cystic acne

Cystic acne typically needs a more intensive initial course than milder presentations:

Each takes 30 to 40 minutes for typical facial cystic acne. The skin is cleansed and eyewear placed. The laser is passed in six passes over the affected areas, with cold-air through the device for comfort. The sensation is warm rather than pain — most tolerate the treatment without .

For deep, particularly large cystic lesions, we sometimes combine the Nd:YAG protocol with focal Er:YAG ablation on the surface of the cyst, accelerating drainage and . This combined approach is reserved for specific situations.

There’s no significant . Mild redness and warmth for a few hours after each session is the typical extent. Strict daily SPF 50 for at least two weeks post-session is essential, as with all laser treatments.

What to expect from results

Most see improvement within the first four to six sessions, with continued over the full three- to course. The pattern typically follows this progression:

Established from past cystic acne won’t fully resolve with the laser acne alone. For patients with significant atrophic scarring, we typically add fractional Er:YAG resurfacing or sessions once the active is under . The both active acne and the scarring legacy of past — something no single can match. See our for the scarring treatment side.

How laser compares with other cystic acne treatments

remains the most powerful single for severe cystic acne and can produce after a six-month course. The downsides — strict contraceptive requirements during and after treatment, blood monitoring, mood effects, of during and for six months after treatment, and a significant list of other side effects — make it the wrong choice for many patients.

Laser is the highest-impact alternative when is contraindicated or . For some patients, laser then isotretinoin (or vice versa) in sequence is the right plan; we discuss this individually at consultation.

Oral help with the component of cystic acne but laser on the depth of effect and on the concerns. courses also have an exit point — laser provides a more sustainable mechanism.

For women whose cystic acne has a clear hormonal (jawline distribution, flare, response to hormonal contraception change), modulation can be very effective on its own. We often hormonal with laser to both the underlying driver and the surface mechanism.

alone are inadequate for cystic acne — they can’t reach the depth where cysts sit. Topicals retain a role in maintenance and in addressing comedonal lesions laser.

Intralesional triamcinolone (corticosteroid into a cyst) can rapidly settle large and is sometimes used for specific cysts ahead of important events. It’s a focal rather than a treatment for the disease, and we use it rather than as .

What we don’t recommend

Frequently asked questions

Most see a meaningful reduction in new lesion by week six to eight of . of cysts varies — smaller lesions often clear within the first month, larger established lesions may take longer.

The collagen-stimulating effect of laser begins addressing early while treating active disease. For more established scarring, we add dedicated scar treatment — fractional Er:YAG or Morpheus8 — once active acne is under control. See for that side of the programme.

No — most patients describe warmth or mild rather than pain. cooling through the laser handpiece reduces further. Topical is rarely needed.

No — we don’t combine concurrent laser with isotretinoin . Skin is too fragile during isotretinoin courses. We typically a wait after isotretinoin completion before laser.

Yes — Nd:YAG at 1,064 nm is one of the safest laser for types IV to VI because less of its energy is by melanin. We adjust and conduct patch where appropriate.

With maintenance sessions every 4 to 6 months, results sustain indefinitely. Without maintenance, gradual recurrence is common — but less severe than pre-treatment.
