Pharos Excimer Laser Treatment at Cahaba Dermatology

Pharos Excimer Laser for Psoriasis, Vitiligo, Hand Eczema, and White Spots

If you’re dealing with stubborn psoriasis plaques, vitiligo, hand eczema, or other lighter skin patches, Pharos Excimer Laser offers a focused, non-surgical treatment option. This targeted 308 nm UVB therapy treats affected areas directly while helping protect nearby healthy skin.

Unlike full-body UVA/UVB light box therapy, Pharos concentrates treatment only where it’s needed. That makes it especially helpful for smaller treatment areas and harder-to-reach locations, like the scalp.

At Cahaba Dermatology, your treatment plan is personalized to your condition, skin response, and goals.

How Pharos Excimer Laser Works and What to Expect

Pharos uses a carefully focused beam of UVB light delivered through a precision handpiece. For psoriasis, this targeted light helps reduce inflammation and overactive skin-cell turnover in plaques. For vitiligo and other hypopigmented concerns, treatment is directed at lighter areas while minimizing exposure to surrounding pigmented skin.

Treatment sessions are typically quick—often about 10 to 15 minutes depending on how many areas are treated. Most patients report little to no discomfort.

For psoriasis, improvement is often noticed after 3–4 treatments, with more significant improvement commonly seen after 6–10 treatments. Clearance may take 10–20 treatments in some cases. Results vary by condition, severity, and treatment consistency.
