Green Tea is harvested from the Camellia sinensis plant. Green tea consists of leaves that haven’t been fermented so they contain the highest level of antioxidants (flavonoids and polyphenols) along with healing compounds:  

  • Linoleic Acid
  • Quercetin
  • Aginenin
  • Methylxanthines // Caffeine // Theobromine // Theophylline
  • Amino acids // Enzymes
  • Catechins 

Studies have found that the benefits of green tea are due to the fact green tea contains more healing compounds than many other herbs, spices, fruits and vegetables, leading to green tea being labelled as a 'superfood.'

Archeological discoveries suggest that green tea has been consumed for over 5,000 years, while other evidence suggests that natives of eastern Asia have been using the potent antioxidant for more than 500,000 years. Traditionally, green tea has been used in Chinese and Ayurvedic medicines as a stimulant, diuretic and astringent. Additionally, it has been observed as a means to regulate the body temperature and blood sugar while promoting digestion and improving the mental process.

We know drinking tea is beneficial to human health but how can green tea be beneficial in skincare?


The process of skin ageing has been divided into two categories:

  1. Intrinsic - Natural ageing is caused by changes in elasticity of the skin over time. 
  2. Extrinsic - Primarily a result of exposure to solar radiation (photoageing). UV exposure causes physical changes to the skin due to alterations that occur in the connective tissue via the formation of lipid peroxides, cell contents, enzymes and reactive oxygen species (ROS)

Environmental Exposure - Acute response of human skin to UVB irradiation includes:

  • Erythema - From the Greek erythros, meaning red - is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation.
  • Edema - The medical term for swelling. Body parts swell from injury or inflammation.
  • Pigment - Darkening followed by delayed tanning
  • Thickening - Of the epidermis and dermis

Chronic UVB effects include:

  • Photoaging - Premature aging of the skin
  • Immunosuppression - The partial or complete suppression of the immune response of an individual 
  • Photocarcinogenesis - A substance which causes cancer, this destructive effect often results from free radicals.

How Green Tea Extract can Help

Extracts of green tea contain: 

  1. Tea polyphenols (catechins): Catchin, gallogatechin, epicatechin, epigallocatechin, epicatechingallate and epigallocatechgallate (EGCG). These polyphenols have antioxidant activity and function as reactive-oxygen-species scavengers. Specifically, the polyphenols scavenge hydroxyl and peroxyl radicals while inhibiting lipid peroxidation and the oxidation of low-density lipoproteins. It is thought that these radicals increase the risk of certain cancers and are partly responsible for the physical appearance of aging.
  2. Catechins - Have anti-inflammatory properties that have been helpful for treating arthritis, gout, dermatosis, and other inflammatory conditions. Efficacy studies have demonstrated that the polyphenols found in green tea are beneficial in providing protection against UVB-radiation.
  3. EGCG - The Green Tea antioxidant responsible for being such a mighty free radical fighter is epigallocatechin gallate, or EGCG. Green tea boasts the highest known amount of any antioxidant, EGCG, which research shows is 100 times more powerful than vitamin C. The polyphenols can also inhibit bacterial growth while acting as an astringent. 


Since inflammation and oxidative stress appear to play a significant role in the aging process, the extract of green tea may have age-defying effects by decreasing inflammation and scavenging free radicals. We have chosen to add Green Tea Extract into the formulation of Certified Organic Superb Serum [face] for the numerous skin care benefits:

  • Tannic acid + Theobromine (compounds) Soothe the skin and remove the heat from sunburn
  • Catechins - Repair skin damage
  • Anti-inflammatory + Antioxidant Effects - Help to reduce the sins of ageing
  • Photoprotective Effects - Reduce the number of sunburn cells, protect epidermis cells reduce DNA damage
  • Vitamin B6 (nico- tinic acid) - Helps in treating a number of skin concerns including eczema, acne, dry skin and psoriasis.
  • Vitamin E  - Helps to block free radicals which play a large part in the aging process
  • Vitamin K - Essential in aiding the body's process of blood clotting, which helps the body heal wounds // bruises
  • Useful also for the treatment of dry skin - by stimulating the formation of ceramides and sphingolipids in the skin and thus reinforcing the lipid barrier.
  • One Study demonstrated: Sunscreen formulated with 2–5% green tea extract has been reported to protect UV irradiation induced photoaging (Li et al. 2009)
  • Natural astringent qualities - Green tea decreases excess sebum production.
