AC Silk Amino Acids PF

As evidenced in a 30-day efficacy study of 2.0% AC Silk Amino Acids PF on skin, moisture levels were improved by 12% compared to aloe vera and 35% compared to baseline measurements.

Phototoxicity (photoirritation) is defined as an acute toxic response that is elicited after exposure of the skin to certain chemicals and subsequent exposure to light. Under the conditions of this assay, the test article substance was considered to be non-phototoxic at concentrations of 0.5%, 1.5%, 5.0%, and 10.0%. The negative and positive controls performed as anticipated. There is a slight decrease in viability at the 10% concentration but viability does not decrease more than the acceptable 20%. We can safely say that AC Silk Amino Acids PF is not a photoirritant when used at the suggested use levels of 1.0% -5.0%.
