Let’s learn skincare Ingredient together -Centella asiatica
Centella asiatica extract
Snow grass, also known as Thunder God Root, Tiger Grass, Horseshoe Grass, etc., is a perennial herbaceous plant in the Umbelliferae family of the Snow Grass genus. It was first recorded in the “Shennong Bencao Jing” and has a long history of application. In traditional medicine, centella asiatica is widely used to treat diseases such as damp heat jaundice, abscess swelling and toxin, sore throat, etc.
In the field of skincare, snow grass also has significant effects. Its extract mainly contains triterpenoid compounds (such as centella asiatica glycoside, hydroxycentella asiatica glycoside, centella asiatica oxalate, hydroxycentella asiatica oxalate), flavonoids, polyacetylene compounds, and other components. Among them, the following four major components are particularly crucial:
Snow oxalic acid: strengthens the skin barrier, anti-inflammatory and antibacterial properties, protects against UV rays, promotes wound healing, and improves elasticity.
Hydroxycentella asiatica glycoside: antioxidant, antibacterial, immune regulating, anti-inflammatory and sedative, promotes skin regeneration, and improves texture. Hydroxyasiatic acid: Reduces scars, calms and soothes, repairs damaged skin.
Centella asiatica glycoside: regulates water oil balance, promotes skin growth, and facilitates collagen synthesis.
The triterpenoids in centella asiatica extract can stimulate the proliferation of fibroblasts and the synthesis of collagen, thereby increasing the elasticity and firmness of the skin.
Its main mechanism of action is to activate specific signaling pathways, such as the TGF – β/Smad signaling pathway, promote collagen synthesis, and accelerate the wound healing process. It has a good repairing effect on skin injuries such as acne, acne scars, and sunburn
Anti inflammatory/antioxidant
The triterpenoids in centella asiatica extract can inhibit the release of inflammatory factors, reduce skin inflammation, and have a soothing and calming effect on sensitive skin, acne prone skin, and other skin types.
At the same time, polyphenols, flavonoids, and other compounds in centella asiatica extract have strong free radical scavenging ability, which can reduce oxidative damage and delay skin aging.
Enhance skin barrier function
Snow grass extract can promote the proliferation and differentiation of epidermal cells, enhance the barrier function of the skin, prevent water loss and the invasion of harmful substances from the outside world.
