Excimer Laser Therapy
Living with skin conditions like vitiligo, psoriasis, or eczema can be frustrating. Especially when creams and traditional treatments don’t bring lasting relief. We offer Excimer laser therapy in Johannesburg, a breakthrough solution that targets only the affected areas with a precise wavelength of UVB light, helping restore healthier skin without damaging the surrounding tissue.
Safe, effective, and dermatologist-led.

Benefits of Excimer Laser Therapy
Every session is designed to reduce inflammation, calm symptoms, and restore your skin’s natural balance.
- Reducing redness, itching, and scaling associated with conditions like psoriasis and eczema.
- Stimulating repigmentation in vitiligo patches by reactivating melanocytes.
- Delivering fast results, often with fewer sessions compared to full-body phototherapy.
- Treating only affected areas, meaning healthy skin is not unnecessarily exposed to UV light.
- Safe and effective for African skin, when administered by a dermatologist with expertise in skin of colour.
Excimer light therapy isn’t just about symptom relief. It targets the root causes of flare-ups, offering long-term improvement in both skin appearance and comfort.
How Excimer Laser Therapy Works
Excimer therapy uses a precise 308nm wavelength of UVB light that has been clinically proven to treat specific inflammatory and pigment-related skin conditions. Unlike traditional light therapy, which exposes large areas of the skin, Excimer technology pinpoints only the affected areas.
Targets
inflammation
The UVB light penetrates the skin to slow down overactive immune cells. This reduces the redness, scaling, and irritation caused by inflammatory conditions such as psoriasis and eczema.
Stimulates pigmentation
In vitiligo, Excimer laser encourages dormant melanocytes (the pigment-producing cells) to reactivate, gradually repigmenting lighter patches of skin.
Minimises
exposure
Because only affected areas are treated, healthy skin is protected from unnecessary UV exposure, lowering risks and improving treatment precision.
Delivers
faster results
Excimer laser delivers a concentrated dose to problem areas, often meaning fewer sessions are needed compared to full-body phototherapy.
This highly targeted, dermatologist-guided approach makes Excimer skin treatments one of the safest and most effective treatments for chronic skin conditions in African patients.
What to Expect
Every skin journey is unique, but here’s a general timeline of what you might experience:
After the first few sessions
Redness, itching, or scaling may begin to calm, and flare-ups often feel less intense. In vitiligo, some patients notice faint repigmentation dots (known as “freckling”) in treated areas.
After 4–6 sessions
Visible improvements become clearer. Psoriasis plaques may flatten and lose their thick scaling, while eczema-prone skin feels calmer and less irritated. Vitiligo patches often start to blend more naturally with surrounding skin.

After 8–12 sessions
Significant changes are typically seen. Psoriasis and eczema flare-ups are under better control, and vitiligo patches often show noticeable repigmentation.
Long-term maintenance
Many patients benefit from ongoing sessions at intervals recommended by the dermatologist, helping to prevent relapses and maintain healthy, comfortable skin.
Some mild redness may occur immediately after treatment, but this usually settles quickly. Unlike harsh systemic treatments, Excimer therapy has no downtime. You can resume your daily routine right away.
Results You Can Expect
Patients often report transformative improvements with Excimer laser therapy.
- Clearer, more even-toned skin.
- Reduced itching, flaking, and irritation.
- Repigmentation in vitiligo-affected areas.
- Fewer and less severe flare-ups of psoriasis or eczema.
- Renewed confidence in appearance and comfort.
