Studied extensively in preclinical rodent models, it activates multiple regenerative pathways simultaneously making it one of the most broadly applicable repair peptides in current research
The An 2019 clinical trial in Annals of Dermatology tested a crosslinked hyaluronic acid microneedle patch loaded with sh-Oligopeptide-1 and Acetyl Hexapeptide-8 against vehicle control in Korean women with peri-orbital wrinkles, and found significant reductions in wrinkle depth and improvements in skin elasticity over 8 weeks [37]
For instance, AtDHAR1 is up-regulated in response to norflurazon, menadione, paraquat, and antimycin A, treatments known to produce reactive oxygen species (Chew et al., AtDHAR2 expression is induced in root cell cultures in response to BSO and chloro-dinitrobenzene (CDNB) (Dixon et al., DHARs are not always regulated in the same manner in response to stress conditions
Moreover, increased levels of these metabolites in the brain downregulate TJ protein expression, especially ZO-1, which increases BBB permeability
All animals were housed at room temperature under a 12/12 h light/dark cycle and had free access to food and water
Microneedling with PDRN and Exosomes Microneedling creates micro-channels that break up pigmentation clusters and open the dermis for maximal penetration of brightening serums and PDRN
