"Skin dryness and itchiness, in particular, are very serious problems in atopic dermatitis, which often lead to additional complications, such as opportunistic infections. In any event, it seems that the reduction of atopic symptomology observed in this study is a direct result of ingested hempseed oil. These preliminary results confirm anecdotal observations of improved skin quality after ingesting modest amounts of hempseed oil on a daily basis over a relatively short period of time."
