Curcumin Nanoformulations for Dermatological Applications: From Nutraceuticals to Nanocarriers

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Nanotechnology‐based delivery platforms enhance the cutaneous administration of curcumin. Loading free curcumin into polymeric micelles, metal‐based nanoparticles, nanogels/hydrogels, liposomes, polymeric nanoparticles, or nanoemulsions/nanocrystals helps address its low solubility, poor stability and limited skin permeation. As a result, these systems
