Skin Benefits of Camellia Sinensis

With the growing cosmetics industry and introduction of plant extracts in this regard, people are returning to natural skincare treatments free of any toxic preservatives. Currently tea extracts including Camellia Sinensis, due to their biological actions, properties, and rich composition have made a huge impact on cosmetics. 

What is Camellia Sinensis?

It is a species of evergreen flowering plant family Theaceae. Its leaves/leaf buds are used to make tea. Commonly known as ‘’tea plant’’, its extract due to multiple constituents, polyphenols, catechins, purine alkaloids, and several other metabolites, have beneficial effects on skin and other organs.

Skin Benefits of Camellia Sinensis:

Whether taking as a beverage or applying topically, Camellia Sinensis leaf extract has proved to be of great benefit to the skin.

Antioxidant:

Tea Catechins, regarded as the most important antioxidant substance in the human diet, contribute a lot to the beneficial effects to the skin. Oxidative stress is the most important factor in the aging of the skin. Natural oxidants like this are helpful in the prevention of this process. [i] Polyphenols in this extract can have moisturizing and protective effects. [ii] Skin roughness is significantly reduced with its use. [iii]

Photoprotective Activity:

Ultraviolet radiations ranging from 280-400 nm are very detrimental to the skin. This extract can absorb ultraviolet radiation in harmful range and may also have scavenging properties for radicles produced by UV radiations. [iv]

Antiaging:

Multiple enzymes including collagenases, hyaluronidase, metalloproteinases, lipoxygenases can have a destructive effect on skin cement lipid. So, Camellia Sinensis by inhibiting these enzymes delays the aging of the skin by preserving hyaluronic acid, elastin, collagen important for the skin. [v] Alkaloids, phenols, and catechins are effective in preventing the formation of cellulite thus further aiding antiaging objective. [vi]

Anti-Inflammatory:

By inhibiting platelet aggregation, cyclooxygenase (COX-1), and thromboxane synthase (TXAS) production in platelet, it produces anti-inflammatory effect even stronger than commonly used non-steroidal anti-inflammatory drug aspirin. It improves skin microcirculation and protects intracellular cement lipids. [vii] [viii]

Cancer Prevention:

UVR can cause non-melanoma skin cancer, of which 10% are malignant cancers, with a significant mortality rate. By its photoprotective effect, Camellia Sinensis can cause protection from such radiations and alleviate the risk of such dreaded consequences. [ix]

Sebum Production/Acne:

Oily skin, a result of excessive sebum production, accompanied by the problem of acne can be solved by the topical application of its extract. It helps reduce sebum production and have anti-greasy effect too. [x] [xi]

Conclusion:

Concluding the discussion. It could be said that Camellia Sinensis and its extracts can improve skin regeneration by its anti-oxidant, anti-inflammatory, and toning properties. It is strongly soothing, protects against harmful environmental influencers, eliminates excess sebum, and improves skin hydration.
