Systematic review of clinical studies of turmeric/curcumin (oral and topical) across skin conditions (acne, atopic dermatitis, psoriasis, photoaging, pruritus and others): several studies reported significant improvement in disease severity versus control, but the authors characterize this as early evidence from a limited set of studies needing further confirmation.

Why this grade

Reasoning trace

Grade C at low certainty. The grade reflects the direction and size of the effect across the 1 publishable source above; certainty reflects heterogeneity, sample sizes, and design quality. What would move it upward: additional well-powered RCTs in the target population that replicate the effect at similar doses. What would move it down: a large null trial, discovery of publication bias, or a retraction of a keystone study.

Dose & form

Studied intake: varies; oral and topical forms studied.
