Ramette and Bartoletti formulated the first protocol for skin chek-up (temperature, sebometry, corneometry, pH meters, lactic acid test, dermographism) and latest, a skin-proof print that allows a three-dimensional skin image.
Evaluation of pHis done with the electrode and the result of this measurement should show the acidity of the skin.
The amount of fat on the surface of the skin is determined by the sebometer. The “Sebometer” device is used. The measurement time is 30 seconds and it is controlled by the chronometer in the appliance. Normal values of sebometry in the forehead area are between 100 – 200; in the cheekbone area they are between 60 – 160 and in the chin are they are between 60 – 100.
Corneometrydetermines the hydration (moisture) of the skin. The instrument “Corneometer” is used. Normal values of hydration vary from 95 to 105.
A15% lactic acid test(Ramette test) can confirm the diagnosis of sensitive skin. Dermographism is useful to determine the degree of hyperreactivity of the skin.
