phloretin
1.2% -
1.5%
Irritation risk:
Concentration: Effectiveness:
MEDIUM
A potent antioxidant that is able to penetrate the skin barrier. It can help neutralize free radicals in skin, fight photodamage and reduce hyperpigmentation. It is, however, unstable and loses effectiveness when exposed to light. Effective products with phloretin must come in air-tight opaque packaging and use a sophisticated delivery technology
epigallocatechin gallate
0.45% -
0.65%
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

Anti-oxidation
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging

Irritation risk:
Works for:

Exfoliation
Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
