Influence of Facial Threading on Various Physiological Parameters of the Skin: Non-Randomized Trial Involving Adult Women in Taiwan

The study on facial threading in 18 adult women in Taiwan found that the procedure significantly reduced skin roughness by 26.74% and improved the subjective feel and appearance of the skin by removing vellus hairs. However, it did not affect skin hydration or melanin indices. The process was similar to exfoliation, enhancing skin smoothness and color, but potential risks included allergic reactions and infections. The study was limited by its non-randomized design, small sample size, and lack of diversity, suggesting the need for future research with larger, more diverse groups and comparisons with other cosmetic procedures.
