If you travel, use an insulated medical cooling case with temperature packs rated for the 2C to 8C range
This is the pigment that causes dark spots, hyperpigmentation, and uneven skin tone
This includes proposed up-regulation of endothelial nitric oxide synthase (NOS3), decreased stimulation of endothelial cells, development of anti-oxidative responses, decreased migration of inflammatory cells, decreased antigen presentation because of suppressed MHC II expression in endothelial cells [57] resulting from promoter IV of class II trans-activator (CIITA) [58], down-regulation of pro-inflammatory cytokines, decreased PLT accumulation, development of 15-epi-lipoxin (15-epi-LXB4), which operates through preventing the signaling pathways engaged in the stimulation of the inflammatory response induced by lipid agents [59, 60] and, finally, enhanced migration, differentiation, and prohibitory functions of Treg cells [59, 61]
So even uh, and the other biggest issue with any drug or any kind of substance is immune reaction
