Product summary
What can the product work for?
Anti-blemish
What does the product description say?
The brand's patented ingredient Anti-Sebum P helps to control sebum production and unclog pores.
niacinamide
1.6% -
2.4%
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
epigallocatechin gallate
0.4% -
0.95%
Irritation risk:
Concentration: Effectiveness:
MEDIUM
A polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincare
camellia sinensis leaf extract
22% -
34%
Irritation risk:
Concentration: Effectiveness:
LOW
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
