epigallocatechin gallate
0.5% -
1.2%
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
1% -
1.5%
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
sodium salicylate

0.25%
Irritation risk:
Concentration: Effectiveness:
LOW
The salt of salicylic acid. Helps exfoliate the upper layer of the skin. Can also work to preserve cosmetic products
