PCA analysis of psychometric variables taking into account (a) two factors, Fl and F2 (62.6% of the total variance), and (b) two factors, Fl and F3 (60.6% of the total variance), based upon nine variables. A correlation circle identifies the parameters responsible for these variances.

The same analysis for class A did not reveal sustainable subclasses. Indeed, the statistical subdivisions revealed a main subclass that regroups 90% of the subjects of class A, with a response profile similar to the general class A profile. DISCUSSION The first result of our study has clearly shown that the women of our panel expressed through a self-assessment questionnaire two opposite functions in facial makeup. The first function is rather intended to decrease a negative self-perception, which we labeled as "camouflage." The second is more oriented to the desire to please, which we labeled as "seduction," with some variations. For one subclass in which the "natural" face is perceived as more valuable than the made-up face, makeup is rather used in "playful" or "enjoyable" contexts and, hence, variability in its features is allowed. For the other subclass, the made-up face is considered as more valuable than the natural face and tends to supports the self-image, thus restricting variability in the makeup structure. In order to go further in the understanding of these functional differences, we tried to relate these Table VI Identification of Three Subclasses of Volunteers Variables STAI (T-anxiety state) SEI (General self score) RAS score EPI Form B (Extroversion-introversion) EPI Form B (Neuroticism-stability) Subclass Bl (n = 16) Mean ±SD 38.3A 3.9 19.4A 1.9 15.3A 13.3 11.7A 3.0 8.lB 3.2 Class B (n = 49) Subclass B2 (n = 23) Mean ±SD 35.lA 5.5 20.0A 2.1 26.7B 16.5 17.0B 2.3 9.lB 2.9 Subclass B3 (n = 10) Mean ±SD 32.2A 6.3 23.6B 1.0 42.0c 15.4 17.0B 2.3 3.lA 1.7 Significance NS S (p 0.01) S (p 0.01) S (p 0.01) S (p 0.01) When there is a significant difference between subclasses for each psychometric variable, we indicate by letters (A, B, C) the subclass to which it belongs.
