Wrinkle Formation Mechanism Research Service
Introduction
Wrinkle formation is a natural process that occurs as skin ages, resulting in the development of fine lines, creases, and folds. This process is influenced by a combination of intrinsic factors, such as genetic predisposition and hormonal changes, and extrinsic factors, including sun exposure, pollution, smoking, and environmental stress. The primary mechanism involves the breakdown of collagen and elastin fibers in the dermis, leading to a loss of skin elasticity and firmness. As these structural proteins degrade, the skin becomes thinner and less resilient, which promotes the formation of wrinkles. Additionally, a decrease in the production of hyaluronic acid and moisture retention in the skin further exacerbates wrinkle formation. UV radiation accelerates these changes by inducing oxidative stress, which damages skin cells and speeds up the breakdown of collagen. Facial expressions, such as smiling and frowning, also contribute to the formation of dynamic wrinkles, which deepen over time. Creative Biolabs provides in-depth services to investigate the mechanisms of wrinkle formation, utilizing advanced skin models and scientific research to evaluate various factors that influence aging skin. With our expertise, we offer tailored solutions for assessing anti-aging treatments and strategies to mitigate the appearance of wrinkles, including topical applications and interventions aimed at restoring skin structure and function.
Services
Creative Biolabs offers a comprehensive range of well-established in vitro and in vivo models for investigating the mechanisms of wrinkle formation. Our models cover various aspects of skin aging, including collagen degradation, elastin breakdown, and the impact of environmental stressors such as UV radiation and pollution. These models are designed to closely replicate human skin physiology, providing a detailed understanding of the molecular and cellular processes involved in wrinkle formation. By simulating both intrinsic and extrinsic aging factors, our models enable the evaluation of cosmetic ingredients and formulations that aim to prevent or reverse wrinkles. Our team of experienced scientists will work alongside you throughout the entire research process, from experimental design to data analysis, ensuring the generation of accurate and reliable results. These insights will assist in the development of effective anti-aging solutions to combat wrinkle formation and improve skin health.

Measurements
We offer a comprehensive set of measurements for evaluating the mechanisms of wrinkle formation, employing a range of advanced techniques to assess various factors contributing to skin aging. Our approach includes, but is not limited to:
- General Observations: Assessment of skin texture, wrinkle depth, and elasticity using non-invasive methods like visual grading scales and skin analysis devices.
- Histological Analysis: Examination of skin tissues for changes in collagen, elastin, and other extracellular matrix components using techniques such as Masson's trichrome staining and elastic fiber staining.
- Molecular Profiling (e.g., PCR and Western blotting): Quantification of key molecular markers related to wrinkle formation, including matrix metalloproteinases (MMPs), collagen, and elastin expression levels.
- Gene Expression Analysis (e.g., RT-qPCR): Detection of age-related genes and inflammatory markers such as IL-6, TNF-α, and MMP-1.
- Proteomics: Comprehensive profiling of skin proteins involved in aging and wrinkle formation using advanced techniques like mass spectrometry.
- Skin Hydration and Barrier Function: Measurement of moisture levels and transepidermal water loss (TEWL) to assess skin integrity and hydration status.

Published Data
Fig. 2 Treatment with vitamin B12 or FA ameliorates UVB-induced wrinkles and MMP2 expression.1
The experiment investigated the effects of vitamin B12 and folic acid (FA) treatment on UVB-induced wrinkles and MMP2 expression in SKH1 hairless mice. Mice were subjected to UVB irradiation three times a week for 16 weeks with gradually increasing doses. After each irradiation, corn oil, B12, or FA was topically applied to the dorsal area of the mice. At week 13, wrinkle formation was evaluated. (A) Representative images were captured of the wrinkles on the lower dorsum of the mice. (B) Wrinkle grading was performed by blinded investigators using the scale developed by Inomata et al. (C and D) Skin sections perpendicular to the wrinkles were paraffin-fixed and stained with DAPI and anti-MMP2 antibody for fluorescence immunohistochemistry (IHC). MMP2 expression bands in each section were identified at 200× magnification, and fluorescence intensity was quantified using ImageJ (NIH). (C) The average fluorescence intensity of MMP2 bands was measured per mouse. (D) Representative images of MMP2 bands (indicated by white arrows) observed under IHC at 200× magnification.
