While their mechanisms of action are similar, topical acetyl hexapeptide-8 does demonstrate a lower efficacy than injected Botox, but as researchers note this is to be expected.22 Similar results were found in a small 2013 study, with the total anti-wrinkle efficacy of the Argireline treatment group being 48.9% compared to 0% in the placebo group.23 However, a more recent 2023 study investigating the effects of serum containing Argireline and hyaluronic acid found the results to be not statistically significant.24 This means that more research is needed before claims that Argireline is a true alternative to Botox can be confirmed or denied
This enzyme is crucial in producing melanin the pigment responsible for skin color
Among these regulatory systems, three have emerged as particularly compelling therapeutic targets due to their pivotal involvement in both physiological and pathological contexts: The excitatory amino acid transporter 2 (EAAT2, also known as GLT-1 in rodents), aquaporin-4 (AQP4), and purinergic receptors, particularly the P2X 7 and P2Y 1 subtypes
