Microrelief suppresses large wrinkling appearance: an in silico study
1Institute of Industrial Science, The University of Tokyo, Meguro-ku, Tokyo, Japan.
Summary
Fine skin microrelief, or surface roughness, can help prevent large wrinkles by suppressing dermal buckling. This finding is crucial for developing new cosmetic and medical treatments for skin aging.
Area of Science:
- Biomechanical Engineering
- Dermatology
- Computational Modeling
Background:
- Facial wrinkling is a significant concern in aesthetic dermatology.
- Existing research often overlooks the role of skin's microrelief in wrinkle formation.
Purpose of the Study:
- To investigate the mechanism of extensive skin wrinkling using finite element simulations.
- To evaluate the specific influence of surface roughness (microrelief) on wrinkle appearance in vivo.
Main Methods:
- Finite element analysis was applied to multilayered elastic laminate models of skin.
- Linear and post-buckling analyses were conducted.
- Models incorporated microrelief to assess its impact on wrinkling mechanisms.
Main Results:
- Wrinkling was observed as dermal buckling initiated by stratum corneum buckling events.
- The presence of microrelief was found to suppress dermal buckling, thus reducing wrinkle severity.
Conclusions:
- The multilayered structure of skin significantly contributes to large wrinkle formation through post-buckling behavior.
- Surface microrelief acts as a barrier against the development of significant skin wrinkles.
- Findings offer valuable insights for developing preventative cosmetic and medical interventions for skin deformation.
