Distribution Feature of Ultraviolet-induced Red Fluorescence on Facial Skin of Patients with Acne

  Objective  To study the distribution feature of ultraviolet (UV) -induced red fluorescence on facial skin of the patients with acne.

  Methods  The (skin analysis system, SAS) is used to obtain UV images of facial skins of 74 acne patients and 68 healthy individuals, and the detection rate of red fluorescence was calculated.

  Results  The detection rate of red fluorescence was 85.14% in 74 acne patients and 33.82% in 68 healthy individuals (χ²=39.064, P < 0.005). Additionally, it was significantly higher in T zone, where sebum secretion is higher, than in U zone, where sebum secretion is lower (χ²=21.806, P < 0.005; χ²=15.429, P < 0.005, respectively).

  Conclusion  UV-induced red fluorescence on facial skin of the patients with acne may be related to sebum secretion.
