Red light therapy boosts collagen, reduces wrinkles, and accelerates skin healing. A safe, non-invasive way to achieve youthful, radiant skin.
Psoriasis is an autoimmune inflammatory skin disease in which skin cells build up into scales and itchy, dry patches. The condition is often misunderstood; one myth is that it is untreatable or affects only one gender or age group. In fact, it can affect men and women equally, and more than 5 million U.S. adults—about 2% of the population—live with the disorder.
Another misconception is that psoriasis is contagious. It is not; it stems from an immune system that functions abnormally.
Among the available treatments, light therapy is one of the oldest, safest, and most widely used approaches for stable psoriatic lesions on the trunk, scalp, arms, legs, or nails. Forms include ultraviolet B (UVB), psoralen plus UVA (PUVA), pulsed-dye laser (PDL), photodynamic therapy (PDT), intense pulsed light (IPL), and light-emitting diodes (LED).
Psoriasis involves rapid skin-cell production. Light therapy slows this excess growth in the epidermis, reducing plaque formation, calming inflammation, and influencing DNA activity within skin cells.
Clinical studies report benefits for:
Light therapy may:
Light can be directed at localized areas such as the hands or scalp, or at the whole body. Sensitive sites like the eyes and genitals are shielded.
Improvement is gradual; multiple sessions are needed, with the dose increased incrementally. A typical course lasts two to three months, though individual response varies.
Portable LED devices now allow some people to continue therapy at home, although results depend on consistent use and proper technique.
