There are few published randomised controlled trials (RCTs) of the effects of acupuncture in the treatment of chronic inflammatory skin conditions such as atopic eczema and psoriasis. Two small RCTs found that acupuncture reduced itch in patients with atopic eczema (Pfab 2011; Pfab 2010). On the other hand, a small RCT of acupuncture for psoriasis concluded that classical acupuncture is not superior to sham acupuncture (Jerner 1997). Sham interventions are not inactive placebos, but effectively different versions of acupuncture, so their value in evaluating treatment efficacy is highly questionable.

In general, acupuncture is believed to stimulate the nervous system and cause the release of neurochemical messenger molecules. The resulting biochemical changes influence the body's homeostatic mechanisms, thus promoting physical and emotional well-being. Stimulation of certain acupuncture points has been shown to affect areas of the brain that are known to reduce sensitivity to pain and stress (Hui 2010)

Acupuncture may help to relieve symptoms in people with atopic eczema and psoriasis by reducing inflammation, by promoting release of vascular and immunomodulatory factors (Zijlstra 2003; Kavoussi 2007);regulating mediators of the allergic reaction to extrinsic allergens, for example Ig-E (Rao 2006), serum cytokines (IL-2, IL-4, IL-10, IFN-, Ig-E) (Okumura 2002), and basophils (Pfab 2011);enhancing natural killer cell activities and modulating the number and ratio of immune cell types (Kawakita 2008);increasing local microcirculation (Komori 2009), which aids dispersal of swelling;
