Characterization of Bacterial and Mycosis Skin Flora in Seborrheic Macular Hypopigmentation - Microbiome

Skin swabs will be obtained from the patient's facial lesional (FLS) and perilesional sites (FPS) using a sterile cotton swab. The microbiota of the same anatomical face regions will be collected on volunteers, once the 10 SMH patients have been enrolled. The swab is premoistened in a specific cocktail solution and rubbed onto the skin surface for 45sec. The pressure during the sampling involves rubbing the area of interest with a smear over the entire zone. The skin reddens slightly under the exerted pressure.
