Melanin oxidative stress
WebOur results suggest that MeCbl was able to reduced H 2 O 2 -induced oxidative injury in melanocytes. Figure 2 Methylcobalamin (MeCbl) reduced the H 2 O 2 -induced oxidative injury of melanocytes. ( A) Melanocytes were pretreated with 10 μM MeCbl for 48 h and then treated with 1.0 mM H 2 O 2 for 24 h. Web29 apr. 2024 · The production of reactive oxygen species (ROS) leads to the generation of oxidative stress, which will result in the excessive production and accumulation of melanin in the body and even the occurrence of some skin diseases. The intervention of antioxidants can slow down the rate of melanin formation to some extent.
