Green Tea’s Therapeutic Properties
In modern times, green tea has become a widely consumed beverage not just for its refreshing flavour but also for its numerous health benefits. Derived from the Camellia sinensis plant, green tea leaves are rich in plant polyphenols, particularly epigallocatechin gallate (EGCG), which contribute to its recognised anti-inflammatory properties and antioxidant properties.
A 2018 study reported that Camellia sinensis leaf extract, especially EGCG, demonstrates multiple protective mechanisms, including:
- Antioxidant
- Anti-inflammatory
- Protection against cardiovascular diseases
- Support in managing diabetes
- Improved resistance to oxidative stress
Additionally, a 2012 review suggested that regular green tea consumption could help strengthen the immune system and offer skin photoprotection, potentially supporting the body’s natural defences against environmental damage.
Green Tea and Acne
Oily Skin and Sebum Regulation
According to a 2016 placebo-controlled clinical trial, EGCG in green tea was shown to exhibit strong anti-inflammatory effects, antimicrobial properties, and the ability to regulate sebum production — all of which are vital for treating acne.
Excess sebum can clog pores and promote bacterial growth, leading to acne. EGCG, classified among other catechins, works as an anti-androgen and helps regulate body temperature and lipid levels in the skin. This reduces oiliness and helps limit breakouts.
Sebum is naturally secreted by sebaceous glands to keep skin hydrated, but hormonal changes — particularly androgens — can trigger an overproduction. EGCG may help calm these fluctuations, making it a valuable component in skincare.
Green Tea and Skin Cancer Prevention
A 2003 study focused on the topical application of green tea extract and its potential for reducing the risk of skin damage and melanoma. The beneficial effects were linked to its antioxidant and immunomodulatory effects, helping to prevent cellular mutations caused by UVB exposure.
This supports the theory that regular green tea use, whether orally or topically, may help delay the onset of wrinkles, prevent dark spots, and reduce the likelihood of both melanoma and nonmelanoma skin cancers.
Green Tea Extract and Skin Health
Acne Management
Research continues to explore the effects of green tea in skincare. In one placebo-controlled trial in 2016, participants took 1,500 mg of oral green tea extract for four weeks. The results showed a noticeable reduction in acne lesions, suggesting a real therapeutic potential for green tea in acne treatment regimens.
Anti-Ageing Benefits
A small double-blind study conducted in 2005 observed improved skin elasticity in women who used a combination of topical application and oral green tea. A later 2013 trial found that cosmetic products containing green tea extract enhanced skin moisture and texture, while reducing sun-related damage.
Green tea’s high levels of amino acids, vitamins, and L-theanine may also support the skin’s stress response and improve its ability to recover from external irritants over time.
Green Tea for Puffy Eyes
For puffiness or mild swelling around the eyes, green tea may offer a simple home remedy thanks to its anti-inflammatory effects and mild caffeine content.
To try it:
- Steep two tea bags using hot water, then allow them to cool.
- Squeeze out excess liquid.
- Place the bags in the fridge for 10 to 20 minutes.
- Gently lay them over your closed eyes for up to 30 minutes.
Although clinical nutrition literature has yet to confirm its effectiveness definitively, green tea’s caffeine may help reduce swelling by constricting blood vessels and calming inflammation.
Precautions Before Using Green Tea on Skin
When applying green tea around sensitive areas like the eyes, consider the following precautions:
- Wash your hands and face beforehand
- Remove makeup and contact lenses
- Avoid tea bags with staples
- Don’t allow any liquid to enter your eyes
Discontinue use if you experience irritation or discomfort, and always consult your doctor before incorporating any new remedy into your routine.
Takeaway
Numerous studies have shown that green tea benefits the skin in more ways than one. Whether used topically or taken orally, this natural remedy offers antioxidant, anti-inflammatory, and immunomodulatory effects that may support clearer, healthier-looking skin.
From reducing acne and controlling oil production to potentially preventing skin cancers and improving elasticity, green tea’s power lies in compounds like EGCG, other catechins, and L-theanine — all of which contribute to its well-established profile.
Incorporating green tea or Camellia sinensis extract into your daily routine may help combat wrinkles, promote balance, and enhance your skin’s ability to resist environmental stressors. As always, consult with a medical professional before beginning any new supplement or skincare regimen, especially if you’re already using other products or dietary supplements.
