[Detection of red fluorescence in the facial skin of healthy individuals and patients with seborrheic dermatitis].

OBJECTIVE

To detect red fluorescence in the facial skin of healthy individuals and patients with seborrheic dermatitis (SD).

METHOD: Skin analysis was performed to obtain the ultraviolet images of the facial skins of 61 healthy individuals and 64 SD patients, and the detection rate of red fluorescence was calculated.

RESULTS

The detection rate of the red fluorescence was 36.06% in healthy individuals and 70.31% in SD patients (χ(2)=14.728, P<0.005). Additionally, it was significantly higher in T zone, where sebum secretion is high, than in U zone, where sebum secretion is lower (χ(2)=11.529,P<0.05;χ(2)=23.757,P<0.05,respectively).

CONCLUSIONS

Red fluorescence exist in both healthy individuals and SD patients, and the detection rate is especially high in the latter. Meanwhile, red fluorescence may be related with sebum secretion.
