TERMINALIA ARJUNA BARK POWDER.

Terminalia Arjuna Bark Powder and its extracts exert their dermatological effects through several pathways. It functions as a strong anti-inflammatory and antioxidant, neutralizing free radicals with its rich content of terpenoids, flavonoids, and phenolic acids, thereby mitigating oxidative stress. For the delicate eye area, it notably improves microcirculation, which effectively reduces puffiness, attenuates the appearance of fine lines and wrinkles, and diminishes the blue pigmentation associated with dark circles. The ingredient also plays a crucial role in strengthening the skin barrier by reducing transepidermal water loss (TEWL) and upregulating key proteins involved in keratinocyte differentiation, such as filaggrin, loricrin, and involucrin, while boosting intercellular lipids like ceramides. Furthermore, it exhibits astringent qualities that help manage excess oil and provides antimicrobial activity against *Propionibacterium acnes* and *Staphylococcus epidermidis*, contributing to its anti-acne potential. Its anti-aging capabilities extend to inhibiting glycation-induced protein cross-linking and suppressing tyrosinase activity, offering benefits for both skin firmness and hyperpigmentation. It can also help restore natural sebum levels, particularly beneficial for menopausal skin, and promotes collagen turnover for wound healing.
