Dermal Aging Mechanism Research Service
Introduction
Dermal Aging refers to the gradual degradation of the dermis, the deeper layer of the skin, which plays a critical role in maintaining skin structure, firmness, and elasticity. Aging of the dermis is influenced by both intrinsic and extrinsic factors. Intrinsic aging is a natural process driven by genetic factors, resulting in a decline in collagen and elastin production, which contributes to the thinning of the dermis and a loss of skin resilience. Extrinsic aging, often caused by environmental factors such as UV radiation, pollution, and smoking, accelerates the breakdown of dermal components through mechanisms like oxidative stress, inflammation, and increased activity of matrix metalloproteinases (MMPs), which degrade the extracellular matrix. There are two main types of dermal aging: intrinsic aging, which occurs naturally over time, and photoaging, which results from prolonged UV exposure. Signs of dermal aging include the deepening of wrinkles, loss of skin tone and elasticity, thinning of the skin, and an increased appearance of blood vessels. These changes are mainly due to the reduction and fragmentation of collagen and elastin fibers. Creative Biolabs offers specialized services for studying the mechanisms of dermal aging, utilizing advanced in vitro and in vivo models to evaluate the effects of various aging processes on dermal structure and function. We provide detailed analysis on collagen and elastin degradation, skin regeneration, and the impact of potential anti-aging agents, assisting in the development of effective anti-aging treatments.

Measurements
We offer a range of advanced measurements for evaluating the mechanisms of dermal aging, utilizing cutting-edge technologies to assess various factors contributing to skin aging. Our assessment approach includes, but is not limited to:
- General Observations: Skin elasticity, wrinkle formation, skin thickness, and appearance of age-related changes.
- Histological Analysis: Examination of dermal structure using H&E staining and immunohistochemistry to evaluate collagen and elastin degradation, fibroblast activity, and extracellular matrix alterations.
- Oxidative Stress Profiling: Measurement of reactive oxygen species (ROS) levels and antioxidant enzyme activities (e.g., superoxide dismutase, catalase) to assess oxidative damage in dermal tissues.
- Gene/Protein Expression Profiling via RT-qPCR and Western Blot: Quantification of key markers of dermal aging such as MMP-1, MMP-9, collagen, and elastin expression.
- Cytokine Profiling (e.g., ELISA): Analysis of inflammatory mediators like TNF-α, IL-6, and IL-8, which are involved in the breakdown of dermal extracellular matrix components.
- Collagen and Elastin Degradation: Evaluation of collagen degradation through specific biomarkers (e.g., hydroxyproline) and elastin fragmentation, providing insight into the breakdown of structural proteins in aged skin.

Published Data
Fig. 2 Sirius Red (left) and Orcein (right) stainings of histological cuts located 1 cm apart (×10 magnifcation) on cheek skin.2
This study investigates microstructural targets that are likely to influence the mechanical properties of skin, with a specific focus on the cheek region. Figure 4 illustrates the differences observed in two histological cuts taken approximately 1 cm apart from the same facial skin explant. In histological section H1, the collagen network appears well-preserved throughout the dermal layers, as shown by Sirius Red staining (left), and no elastotic material is detected, as indicated by the Orcein staining (right). In contrast, histological section H2 shows considerable damage to the skin structure: the collagen network is severely degraded across the dermis, particularly in the papillary dermis. This area is notably associated with the accumulation of elastotic material, as highlighted by the arrows. These findings provide insight into the microstructural changes that impact the skin's mechanical properties and could guide future studies on skin aging and elasticity.
