This study examined the effects of THC and CBD on human skin models to determine if they could assist in wound healing and slow the process of skin cell aging, or senescence. It was published in December 2022 in the journal Cells.
The results were very encouraging, as both THC and CBD seemed to have a profound impact on cell healing and repair. THC seemed to have stronger anti-aging effects, and the authors concluded that it has "therapeutic potential for cosmetic applications" based on their results.
The author's conclusions:
THC and CBD stimulated fibroblasts’ ability to close damaged wounds, while THC induced wound healing better than common nutrient signaling regulators
THC reduced morphological alterations in skin cells, potentiated cellular viability via preserving cell-cycle regulators, and boosted ECM production
Our data helps fill the gap regarding the potential role of THC/CBD in anti-aging research and demonstrates THC has therapeutic potential for cosmetic applications.
