PARAMETERS INCREASING
TEWL Lactic acid
Oxidative stress Oxidized squalen (in sebum)
Wrinkles (nasolabial folds) Pigment spots
Carbonylated proteins (in
stratum corneum)
Heavy metals and/or dusts deposits
Roughness Inflammatory reactions,
Sensitivity, reactivity Dull skin
BEFORE cleansing AFTER cleansing
Consequently, the skin and scalp are irritated, more reactive and more sensitive.

producT effecTiveness measuremenTs
Dermscan provides advice on the most relevant parameters to be measured according to the expected efficacy of your products. We offer protocols for skin or hair for laboratory use (deposition of fine particles) or for use in a polluted urban environment.

example of proposed TesTs
skin oxygenation (tcpo2) before, then 4 h and 24 h after application of an anti-pollution product
Repeated exposure to pollution causes significant changes to skin parameters as:
