Frequently Asked Questions

Edafence is an extract of the only native grass to survive extreme environmental condition in Antarctica.  Edafence is responsibly sourced and helps to mitigate the damaging effects of pollution and other environmental stressors on the skin.  Edafence helps maintain cellular viability and helps prevent DNA damage to the skin. 

Antioxidant serums help neutralize nasty free radicals that can affect your skin. Free radicals are unstable molecules that try to steal electrons from your skin’s barrier. Antioxidants have an electron to spare and use that to neutralize the free radicals. This can lead to more even skin tone and a reduction in fine lines after consistent use.

Skincare regimens are all unique and what works best for your skin may be different than what drives results for others. If trying to combat hyperpigmentation, we recommend using Antioxidant Defense Serum in the AM and our Brighten KNR Serum in the PM for a synergistic approach of defending against the future formation of dark spots as well as helping to reverse the signs of photo damage that has already occurred. Incorporating a Tensage Intensive Serum into a regimen is also an excellent way to jumpstart results.
