green tea (extract) powder
Green tea extract is 20 times more antioxidant-active than Vitamin C, making it a great anti-ageing product, and it also has calming, anti-redness properties.
The scavenging effect of lipid free-radicals (one antioxidant property) of polyphenols in green tea extracts can be clearly observed in experiments.
This powder (extract) makes an excellent addition to many cosmetic products for the following reasons:
As green tea is so antioxidant-rich, it prevents oxidative damage to skin's cells, which otherwise would turn into free radicals - which cause ageing. By keeping your body full of antioxidants it reduces the likelihood of getting wrinkles so you can stay looking younger for longer.
Research has shown that green tea can help to slow down the production of excess skin cells that seems to be the underlying cause of conditions like psoriasis. When applied topically, it can help to soothe the irritation and redness associated with psoriasis.
Reduces Redness in Rosacea
In a controlled study, green tea was shown to provide far superior redness reduction than a placebo. This was from using topical cream infused with green tea. This is most likely due to the calming effect green tea has, as well as the antioxidants going to work on the problem.
Protects Skin from Sun Damage
As green tea protects skin from sun damage, it is ideal for use in sunscreen products. The antioxidants it contains won't necessarily block the sun’s rays, but they will help to mitigate the damage that is done to the skin from the sun. The free radicals that help UV rays cause damage are neutralized, and the green tea helps with inflammation as well.
As green tea is a strong anti-inflammatory, it can help reduce acne. Studies have also shown that topical green tea can cut sebum production by 50%, reduce acne by 50% - (that’s as much as benzoyl peroxide) and reduce skin’s genetic sensitivity to acne-causing androgen hormones.
