Green Tea Leaf - A Skin Savior

Green Tea is harvested from the leaves 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 these healing compounds:  

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

Studies have noted the benefits of green tea are due to the fact green tea contains more healing compounds than many other herbs, spices, fruits, and vegetables, resulting in green tea being labeled 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 body temperature and blood sugar while promoting digestion and improving the mental process.

How Can Green Tea Be Beneficial In Skincare?


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

  1. Intrinsic - Natural aging is caused by changes in elasticity of the skin over time. 
  2. Extrinsic - Primarily a result of exposure to solar radiation (photoaging). 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)


 - 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.


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

How Green Tea Leaf Can Help?

Green Tea Leaf Supercritical extract has a subtle green tea scent and is composed primarily of esters, fatty acids, and fatty alcohols. 

Tea 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.

Phospholipids - Are comprised of two types of fatty acids. That puts them in the lipid family, a broad group of naturally-occurring molecules which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K). The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.

Phospholipids are described as having heads and tails, the 'head' of a phospholipid is hydrophilic [attracted to water], while the hydrophobic 'tails' repel water. This means that they attract water and hold on to it. Hello, moisturizer!

The heads and tails organize themselves into bio-layers that gives them a structure similar to that of skin. Because of this, it is said that products that contain them have an affinity with the skin and high tolerance. Phospholipids retain their structure when applied and because of this is sometimes called a “second skin", without the feeling of being occlusive.

Fatty Esters - Are emollients, meaning they moisturize, soften and smooth the surface of the skin. Fatty acid esters support the skin's water-holding capabilities to help preserve elasticity.

CONCLUSION / Inflammation and oxidative stress play a significant role in the skins aging process, the bioavailable compounds found in green tea leaf extract can aid in decreasing inflammation and scavenging free radicals. I have chosen to add Green Tea Leaf Extract into the formulation of TANUCell Affinity Coactive Serum for the numerous skincare benefits:
  • Protects against TEWLHelps reduce Transepidermal Water Loss (TEWL), contributing towards skin barrier repair.
  • Anti-inflammatory + Antioxidant Effects - Help to reduce the early signs of dermal aging.
  • Photoprotective Effects - Reduce the number of sunburn cells, protect epidermis cells to reduce DNA damage.
  • Useful for the treatment of dry skin - Fatty Acids have a natural affinity for skin, they help to reinforce and smooth skin’s surface, increase hydration without feeling heavy, and help keep skin hydrated. Calm damage (redness and sensitivity) caused by external stressors, aiding in the delivery of antioxidants thus reinforcing the skin's 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)
