EMPETRUM NIGRUM LEAF EXTRACT.

This potent extract functions as a robust antioxidant, safeguarding skin cells from oxidative stress by neutralizing damaging free radicals, attributed to its rich content of vitamins, minerals, flavonoids, polyphenols, and anthocyanins. It actively supports and strengthens the skin barrier by upregulating key barrier genes and enhancing AQP3 and OCLN protein expression, which leads to improved skin restructuring and increased corneocyte cohesion. Consequently, this action intensely hydrates the skin and significantly reduces transepidermal water loss (TEWL). Furthermore, Empetrum nigrum exhibits strong anti-inflammatory effects through COX2 inhibition and suppression of pro-inflammatory mediators, effectively calming irritation and reducing redness. It also offers photoprotection by absorbing UVB radiation and scavenging UVB-induced reactive oxygen species (ROS), thereby preventing cellular damage. The presence of natural acids contributes to gentle exfoliation, promoting cellular regeneration and a smoother skin texture.
