However, it's important to patch test before use and follow up with a good moisturizer and sunscreen to maintain skin health and hydration
Most serums on the market contain less than 1% GHK-Cu
Notably, senkyunolides, core bioactive compounds derived from traditional anti-migraine herbs like Ligusticum chuanxiong , have emerged as promising candidates due to the role of multidimensional homeostasis in regulating neurovascular units (suppressing activation of the trigeminal vascular system, modulating pathological vascular alterations, modulating neurotransmitters and receptors, inhibiting inflammatory response, antioxidant stress and analgesic effects and improving blood-brain barrier integrity) and unique pharmacokinetic advantages (small-molecule structure enabling blood-brain barrier penetration, natural origin reducing hepatorenal toxicity risks)
However, the cell death, proteasome inhibition and apoptosis were observed using 1 mM ibuprofen, which is significantly higher than the peak ibuprofen concentrations found in human blood (58.4 g/mL or 283.09 M) after high doses of ibuprofen 39 , and as such may not be physiologically relevant
