*Results based on a 4-week clinical & consumer study on 58 Asian subjects living in a polluted, urban environment. Stronger skin results based on skin strength index = composite average score of skin suppleness, plumpness and resiliency.
*Formula penetration results based on a clinical study of
25 panelists measuring the penetration of the full formula
via tape stripping.

*Results based on the inhibition potential of sebum peroxidation
compared to untreated skin using a polluted model consisting of
UV and cigarette smoke.
