In concordance with numerous treatment options, some adverse effect might. Recently, it has been discovered that polyphenols may provide satisfactory results for AD therapy and patient’s QoL.
 Objectives: This literature review objective to summarize recent research the use of polyphenols for AD therapy.
 Methods: This is a literature review. Literature search was conducted in Pubmed, EBSCOHOST, Proquest, and Google Scholar, using keywords: “atopic dermatitis”, “atopic eczema” and “polyphenols”. Inclusion criteria were: 1) Randomized clinical trials, case reports, case series, literature reviews, systematic reviews, meta-analysis, cohorts, and experimental studies, 2) Available in full text, 3) Written in English, 4) Research studies with intervention conducted in human, 5) Research studies from early 2000s . While article with lack of available data is excluded. The author use Dermatology Life Quality Index (DLQI) to assess the role of polyphenols in QoL for AD.
 Results: The use of polyphenols in AD shows satisfactory results through their antioxidant, anti-allergic and anti-inflammatory properties. Several studies have observed improvements in sleep disturbance scores, itchiness, and levels of skin moisture and elasticity levels in patients with AD.
 Conclusions: Polyphenols use in AD provide satisfactory results in reducing symptoms that interfere with QoL. However, due to the limited number of studies conducted on human, further studies of larger-scale participants are needed to confirm the effect of polyphenols in AD treatment.
