45 Min
Peelings : Definition & Classification of Tenenbaum

Peelings for MD & Cosmeticians
Dangerous Peelings

How to choose an acid and modulate it : Play with pH and pKa

Dr.Alain Tenenbaum
20 Min
Keratoregulators and Moisturizers

pH skin = 5.5
pKa <pH and pKa >pH
Variations of pH with many factors

Dr.Alain Tenenbaum
25 Min
Penetration Factors

Penetration factors allow to transform a superficial peel into a medium one and a medium one into a deep one with
-thermic reaction
- lipoic acid
- decreasing the pH and increasing the concentration of the acid
