Irritation

May cause irritation or a contact rash; avoid assuming all extracts are gentle.

Can cause irritant or allergic dermatitis, especially when oxidized; never swallow it.

Sensitive skin

Choose a simple formula and test a small area first. Individual tolerance matters more than an ingredient’s reputation for being gentle.

Strengths and forms

Concentrations

Green tea extract and purified EGCG are different preparations. Their percentages cannot be compared without knowing the amount and stability of the relevant catechins.

Choosing a strength: Look for a standardized extract or named catechin and human evidence for the finished formula.

Higher strengths: A higher extract percentage has not been established as better for acne or routine skin care.

Formula matters: A small clinical study of topical EGCG does not establish a universal percentage range for green tea toners, creams, or serums.

Tea tree oil has limited clinical evidence for acne in formulated topical products. The studied concentration is not a reason to use undiluted essential oil.

5%

Acne gel studied

A small randomized placebo-controlled trial found improvement with a 5% tea tree oil gel over 45 days. This does not establish equivalence to standard acne medicines.

Choosing a strength: Choose a finished topical product with directions for use; stop if it causes irritation.

Higher strengths: Higher concentrations have not been established as more effective and may increase irritation or allergic reactions.

Formula matters: Tea tree oil must not be swallowed. Aged or oxidized oil can be more likely to cause an allergic reaction.

Safety and sensitive skin

Common reactions

May cause irritation or a contact rash; avoid assuming all extracts are gentle.

Can cause irritant or allergic dermatitis, especially when oxidized; never swallow it.

When to stop

Stop for persistent burning, swelling, blistering or a new rash. Seek urgent care for breathing difficulty or a severe allergic reaction.

How it works

In the skin

On the skin. The finished product delivers green tea extract in a particular vehicle.

Entering skin. No single molecular mass. The 500 Da guideline cannot be applied to this whole ingredient family or mixture.

Conversion. No activation step is established as necessary for its intended topical role.

Skin response. EGCG affects sebum and inflammatory pathways in experimental models; extracts differ in concentration and stability.

Additional effects. Proposed pathways do not establish a measured depth of delivery or clinical benefit beyond the studies cited.

Common questions

Green Tea Extract:What should I choose green tea extract for?

Consider as optional acne-supporting skincare, with modest expectations.

Green Tea Extract:How strong is the evidence?

An eight-week randomized split-face study examined EGCG alongside laboratory work. It does not establish all green-tea products as acne, rosacea or melasma treatments.

Tea Tree Oil:What should I choose tea tree oil for?

Consider only a properly formulated acne product; standard acne medicines have broader evidence.

Tea Tree Oil:How strong is the evidence?

A small placebo-controlled trial supports a 5% acne gel. Other trials compare active products; they do not establish benefit for every fungal infection, scalp condition or undiluted oil.
