Netsvyetayeva I, et al. - Authors aimed to assess if patients who underwent the hyaluronic acid (HA) injection procedure and developed late bacterial infection (LBI) had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure without any complications. Findings supported that patients with LBI had different bacterial flora on the skin compared to the control group. S. epidermidis dominated the control group’s bacterial skin flora. Among patients with LBI, potentially pathogenic bacteria dominated the bacterial skin flora.
