Summary
Menopause leads to asymmetric facial skin aging, specifically affecting biological elasticity and creep extension in post-menopausal women. This asymmetry is less pronounced in premenopausal women, highlighting changes during the menopausal transition.
Area of Science:
- Dermatology
- Gerontology
- Biophysics
Background:
- Climacteric skin aging impacts facial skin's biophysical properties.
- Facial skin aging is a significant concern during menopause.
Purpose of the Study:
- To evaluate the symmetrical involvement of facial cheeks in climacteric skin aging.
- To compare skin viscoelasticity between premenopausal and post-menopausal women.
Main Methods:
- Compared skin viscoelasticity on both cheeks of 84 women (36 premenopausal, 48 post-menopausal).
- Utilized a computerized suction device to measure skin unfolding, intrinsic distensibility, biological elasticity, and creep extension.
- Controlled for chronic sun exposure by selecting women with indoor occupational activities.
Main Results:
- Post-menopausal women exhibited asymmetry in biological elasticity and creep extension between cheeks.
- Premenopausal women showed less pronounced differences in these viscoelastic parameters.
Conclusions:
- Facial skin viscoelasticity becomes asymmetric after menopause.
- Future anti-aging and hormone replacement therapy studies should consider this facial asymmetry in menopausal women.

01:19The Effect of Aging on Tissues
3.6K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:12Elastin is Responsible for Tissue Elasticity
2.4K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

01:14Changes in Skin Color: Clinical Perspectives
3.6K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:12Renewal of Skin Epidermal Stem Cells
2.4K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:24Facial Feedback Hypothesis
953
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

01:15Reticular Dermis
4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...
