Sensitive Skin

Question 1

BarPore 42

Answer 1

1. lecithin
2. reinforce skin barrier and avoid pollution-induced nerve elongation
3. increases tight junction between cells under SC; limits sensitivity by acting on nerve elongation
4. tests/proof:
   
   • in vivo @ 0.2% lowered TEWL
   • in vitro: stimulates ceramides reinforcing 1st barrier of skin
   • in vitro: stimulates 2nd skin barrier
   • air pollution decreases Sema3A genes which causes nerves to grow and sensitivity: BarPore increases Sema3A gene creating less sensitive skin

Question 2

Cortinhib-G

Answer 2

1. Helichrysum italicum (France/Italy)
2. counteracts effects of cortisol, strengthens barrier,
   instant anti-stinging
3. controls causes of cortisol production, which
   reduces inflammation, decreases TEWL, sensitivity,
   reactivity
4. tests/proof:
   -2% anti-inflammatory effect
   -2% counteracts cortisol effects on barrier
   -reinforces barrier and epidermal cohesion
   -decreases TEWL
   -instantly reduces stinging (lactic acid test)
