Psoriasis is an autoimmune disease in which the patient has an oversensitive immune system and ends up attacking the healthy skin cells. They will form plaques of thick, itchy, and inflamed skin and cause a lot of discomfort and possible complications.
The good news is that the FDA has recently approved an alternative at-home treatment for cases of mild psoriasis. This device is easy to operate and gentle in use. It is patched with LED blue lights which makes it safer than the phototherapy performed at clinics, so it avoids premature skin aging and cancer.
The LED blue lights act at a particular wavelength that is known to reduce the accelerated proliferation of keratinocytes (skin cells) and decrease the inflammatory response caused by the disease.
More traditional devices can only be used on the leg and arms, but the new ones are portable and facilitate the use of other parts of the body. Either way, this therapy has been demonstrated to bring great results. Some clinical studies about the topic showed a continuous improvement with only four weeks of use proving the efficacy of blue light devices. There was a reduction in the amount of damaged skin where the patch was applied. There was less redness, less scales, along with an improvement in the skin aging signs.
There are no serious side effects, only minor inconveniences that are rare but can happen, like skin darkening around the treated area (which will fade over time and after the treatment is done).
Another great thing is how you can do the treatment at home while working or doing a hobby. It will avoid time-consuming visits to the dermatologist and applying a complicated routine of medications. It is recommended to consult a doctor before starting to use these devices, so you will have proper instructions and professional follow-up to obtain the best results possible!
