TEA

📋 Quick facts

Description: TEA — Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of Camellia sinensis, an evergreen shrub native to East Asia which originated in the borderlands of south-western China, north-east India and northern Myanmar. Tea is also made, but rarely, from the leaves of Camellia taliensis. After plain water, tea is the most widely consumed drink in the world. There are many types of tea; some have a cooling, slightly bitter, and astringent flavour, while others have profiles that include sweet, nutty, floral, or grassy notes. Tea has a stimulating effect in humans, primarily due to its caffeine content..

Proven Benefits At A Glance:

• TEA can refer to tea tree oil (from Melaleuca alternifolia) or green tea (Camellia sinensis)—they’re completely different ingredients
• Tea tree oil has been used in Australia for nearly 100 years and is known for antimicrobial and anti-inflammatory properties
• Green tea contains compounds called polyphenols that can neutralize reactive oxygen species (molecules that damage skin)
• Research quality on TEA’s skincare benefits is mixed; some uses have limited evidence and need more studies
• Tea tree oil should only be used topically and never taken by mouth

🔬 The Science

TEA in skincare actually refers to two distinct ingredients, and it’s important not to confuse them. Tea tree oil comes from the Australian Melaleuca alternifolia plant and has been used traditionally for nearly 100 years (Clin Microbiol Rev, 2006). Green tea, by contrast, comes from Camellia sinensis and contains caffeine, an amino acid called l-theanine, polyphenols (including a compound called quercetin), and tannins (peer-reviewed journal, 2006). For tea tree oil specifically: #1: The oil is recognized for antimicrobial and anti-inflammatory actions, which have historically driven its use (Clin Microbiol Rev, 2006). However, a 2023 systematic review of clinical trials found that evidence for most applications is limited (Front Pharmacol, 2023).

#2: For acne, more evidence is needed to confirm benefits for reducing lesions and severity (Front Pharmacol, 2023). #3: The oil’s local anti-inflammatory effects on skin require further study to understand fully (Front Pharmacol, 2023). #4: When used topically at typical concentrations, side effects are generally minor, though 60% of studies did report some side effects; concentrations of 25% or higher can cause more serious reactions (Front Pharmacol, 2023). Important safety note: tea tree oil should never be taken orally and contains compounds with estrogenic activity, so topical application near the breast should be avoided unless thoroughly removed before nursing (peer-reviewed journal, 2006).

For green tea: #5: In one small study, green tea showed a synergistic effect when combined with red light therapy—participants using green tea-soaked pads once daily before light treatment achieved skin rejuvenation and reduced wrinkles in 1 month, compared to 10 months with light treatment alone (Photomed Laser Surg, 2009). This benefit appears to stem from green tea’s ability to neutralize reactive oxygen species, molecules that accumulate in skin and contribute to aging (Photomed Laser Surg, 2009). However, this was a single study with limited details, so results should be viewed cautiously. The broader research base on green tea for skincare is not detailed in these sources.
