CBD enhances cell viability, reduces ROS, lipid peroxidation, and LDH release in UV-exposed keratinocytes and melanocytes. It also upregulates NRF-2, HOMX1, and PPARγ, and downregulates NF-κB and MMP-9 in various cell types. CBD shows anti-inflammatory effects in TNF-α and poly-(I:C)-treated HaCaT cells, and reduces paw edema in carrageenan-induced inflammation in rats and mice. Clinical studies indicate CBD improves psoriasis, atopic dermatitis, and acne symptoms, enhances wound healing, and combats aging effects.
