Gallic acid powder is a phytochemical derived from various herbs and has anti-fungal,anti-viral and anti-oxidant properties. Gallic acid is tannin,a kind of astringent ingredient.It makes the skin look firmer,tighter and less porous.Uses: It has powerful antioxidant,anti-inflammatory,anti-microbial and anti-cancer activities.According to reports,the most fascinating benefit is used for on the skin as a skin lightening and skin lightening ingredient.
Gallic acid in the treatment of UV-induced skin photoaging:
The mechanisms by which GALLIC ACID protects skin from UV-induced skin damage are multifaceted. Available evidence suggests that GALLIC ACID reduces UV-induced production of matrix metalloproteinases, thereby reducing collagen degradation. In addition, GALLIC ACID up-regulated Nrf2 (Nrf2 is a transcription factor that controls the expression of several genes encoding antioxidant proteins and cytoprotective mechanisms). Evidence on the effectiveness of GALLIC ACID in preventing photodamage is limited (see table below). A recent study showed that topical treatment of GALLIC ACID (10 μmol/L) in SKH-1 hairless mice resulted in fewer skin wrinkles after 8 weeks of exposure to UVB compared to untreated mice .
