Resumo

LIN, Li-Ying  e  CHIOU, Shang-Chia. Influence of facial threading on various physiological parameters of the skin: non-randomized trial involving adult women in Taiwan. An. Bras. Dermatol. [online]. 2018, vol.93, n.5, pp.659-664. ISSN 1806-4841.  http://dx.doi.org/10.1590/abd1806-4841.20186865.

Background:

Facial threading involves the removal of hairs to restore facial skin smoothness. However, its effectiveness has not been rigorously evaluated.

Objective:

To evaluate effects of facial threading on skin roughness, hydration, melanin index, and vellus hair on the face, complemented by a subjective evaluation of the tactile feel of the skin and improvement in skin color.

Method:

Participants who had not used exfoliators for two weeks before the experiment were included. Each participant underwent one session of facial threading every 21 days, for a total of 3 sessions. A three-dimensional skin roughness instrument and a multifunctional skin testing system were used to evaluate changes in roughness, hydration, and pigmentation on the forehead, cheeks, and corners of the mouth. A photomicrographic camera was used to record changes in vellus hair. Subjective reports of skin smoothness and color were recorded.

Result:

Eighteen participants completed the study. Facial threading produced a significant decrease in skin roughness on the forehead (22.42%, p = .013), right cheek (77%, p = .02), and left corner of the mouth (33.02%, p = .001). Subjective improvement in tactile feel of the skin and coloring were reported.

Study Limitations:

The study did not include randomization, with further limitations of a small sample size and a single site.

Conclusion:

Facial threading reduced skin roughness by 26.74% after three threading sessions, with improved subjective assessment of tactile feel and coloring. Future research should include a comparison with other cosmetic products with similar beautifying effects or a control group.
