Grenz Ray Therapy

    A gentle, targeted treatment for chronic skin conditions

    What is Grenz Ray Therapy?

    Grenz Ray Therapy is a specialised, very low‑energy radiation treatment used to treat certain chronic skin conditions.

    It works only on the top layer of the skin (the epidermis), which means:

    • Treatment is highly targeted
    • Deeper tissues are not affected
    • Long‑term side effects are minimal and uncommon
    What conditions can it help?

    This treatment may be suitable if you have long‑standing skin conditions that have not improved with other treatments, including:

    • Psoriasis
    • Chronic eczema
    • Lichen planus
    • Disseminated superficial actinic porokeratosis (DSAP)
    • Palm and sole (hand/foot) skin conditions
    • Other inflammatory skin disorders
    When is it used?

    Grenz Ray Therapy is often considered when:

    • Creams or ointments haven’t worked
    • Light therapy (PUVA) hasn’t helped
    • Other medications have not been effective or are not suitable

    It offers an option before moving to stronger systemic treatments.

    What does treatment involve?
    • Short, simple outpatient sessions
    • Usually once a week for 4–6 weeks
    • No injections, no need for anaesthetic
    • You can return to normal activities straight away
    Is it safe?

    Yes. Because the treatment only affects the surface of the skin, it is generally very well tolerated.

    Possible side effects are usually mild and temporary:

    • Slight redness
    • Dryness of the skin
    • Mild, temporary thinning of hair in the treated area

    Most people find the treatment comfortable and painless.

    How effective is it?
    • Around 70% of patients see improvement or good control of symptoms
    • Some patients experience long‑lasting relief
    • Treatment can be repeated if symptoms return
    Why consider Grenz Ray Therapy?
    • Targeted to the problem area only
    • No systemic (whole‑body) side effects
    • Simple and convenient treatment process
    • Useful when other treatments have not worked
