Irritation risk:
Concentration: Effectiveness: HIGH
Is produced by a yeast that lives on normal human skin. It is used in medicine as a topical treatment for mild to moderate acne. It has a mild exfoliating effect. It can also help reduce hyperpigmentation, helps calm down inflammation and can help neutralize free radicals

5.3%
Irritation risk:
Concentration: Effectiveness: HIGH
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.
The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production

Irritation risk:
Concentration: Insufficient!
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
