How Does Light Therapy Work? A Guide for Psoriasis and Eczema Relief
Share
Living with chronic skin conditions such as psoriasis or eczema can be frustrating—especially when flare-ups affect your comfort, confidence, and daily life. Many people try creams, ointments, and even oral medications, yet still struggle to find lasting relief. This is where light therapy becomes a game-changing solutionBut how does light therapy work, and why has it become one of the most effective treatments for these skin concerns?
In this guide, we’ll break down the science, benefits, and how you can use UVB Light Therapy Lamps from Australian Psoriasis and Eczema Supplies to get results at home.
What Is Light Therapy?
Light therapy—also called phototherapy—is a treatment that uses targeted wavelengths of light to address skin conditions. For psoriasis and eczema, the gold standard is narrowband UVB light therapy, which uses wavelengths in the 311–313 nanometre range.
This range is ideal because:
-
It slows down the overproduction of skin cells linked to psoriasis.
-
It reduces redness and inflammation without harming healthy skin.
-
It’s backed by decades of dermatology research for safety and effectiveness.
Unlike sunlight, which contains harmful UVA rays, narrowband UVB focuses on the therapeutic spectrum for skin healing.
How Does Light Therapy Work on Psoriasis and Eczema?
The power of light therapy lies in its effect on skin cells and immune system activity.
1. Slows Rapid Skin Cell Growth
In psoriasis, skin cells can multiply up to 10 times faster than normal. UVB light penetrates the skin, signalling cells to slow down production. This helps reduce thickening, flaking, and scaling.
2. Calms the Immune System
Both eczema and psoriasis involve overactive immune responses. Narrowband UVB can help reset this activity, lowering inflammation and redness.
3. Encourages Skin Healing
By reducing inflammation and normalising cell turnover, light therapy allows skin to heal more effectively. Many users notice smoother texture and reduced itch.
