Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

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 cells,...
Tissue Renewal without Stem Cells01:23

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...
The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

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...

    Summary

    Radiofrequency (RF) treatments for facial and neck rejuvenation are growing, with research shifting towards patient satisfaction. While the US leads global output, broader international collaboration is needed for comprehensive patient-reported outcomes in RF skin rejuvenation.

    Area of Science:

    • Dermatology
    • Aesthetic Medicine
    • Biomedical Engineering

    Background:

    • Radiofrequency (RF) devices are widely used for non-invasive facial and neck rejuvenation, stimulating collagen production and dermal remodeling.
    • While RF efficacy and safety are established, a comprehensive synthesis of patient-centered outcomes is lacking.
    • Understanding global research trends is crucial for advancing RF applications in aesthetic medicine.

    Purpose of the Study:

    • To map global research trends in RF for facial and neck rejuvenation from 2015-2025.
    • To analyze trends focusing on efficacy, safety, and patient-reported outcomes.
    • To identify research productivity, collaboration patterns, and thematic evolution in the field.

    Main Methods:

    • A bibliometric-systematic literature review following PRISMA 2020 guidelines.
    • Searches conducted in PubMed, Embase, Cochrane CENTRAL, and LILACS for English-language studies (2015-2025).
    • Bibliometric analysis using Scopus data in R (Bibliometrix, Biblioshiny), assessing performance, co-authorship, co-citation, keywords, and thematic evolution.

    Main Results:

    • 44 studies met inclusion criteria from 1446 records, with annual publication growth averaging 7.2%.
    • The United States, South Korea, and China dominated research output and citations.
    • Research focus evolved from device parameters and safety to clinical outcomes and patient satisfaction, with keywords like 'wrinkles,' 'skin laxity,' and 'patient satisfaction' being central.

    Conclusions:

    • RF rejuvenation research has matured, increasingly emphasizing patient-centered outcomes over technical aspects.
    • Research productivity is geographically concentrated, with limited international collaboration and underrepresentation from Latin America and Africa.
    • Enhanced international collaboration and consistent use of patient-reported outcome measures are recommended for future RF rejuvenation research.
