Insights

Topical cosmeceuticals can combat skin aging by repairing DNA damage and reducing oxidative stress. Ingredients like DNA repair enzymes and antioxidants help prevent wrinkles and other signs of aging.

Area of Science:

  • Dermatology
  • Cosmeceuticals
  • Molecular Biology

Background:

  • Skin aging results from accumulated cellular and extracellular damage.
  • Environmental factors like solar radiation and reactive oxygen species accelerate skin aging.
  • Clinical signs of skin aging include wrinkles, age spots, and dark circles.

Purpose of the Study:

  • To explore the role of topical active ingredients in preventing and reversing skin aging.
  • To highlight the importance of sunscreens and antioxidants in mitigating UV-induced damage.
  • To discuss novel cosmeceutical approaches for managing skin aging.

Main Methods:

  • Review of scientific literature on skin aging mechanisms and topical treatments.
  • Analysis of the efficacy of deoxyribonucleic acid (DNA) repair enzymes, antioxidants, and anti-inflammatory agents.
  • Discussion of liposomal delivery systems for active ingredients.

Main Results:

  • Sunscreens are crucial for preventing solar radiation damage.
  • Liposomes with DNA repair enzymes accelerate pyrimidine dimer removal post-UV exposure.
  • Antioxidants decrease secondary UV-induced damage, especially from singlet oxygen.

Conclusions:

  • Topical application of active ingredients can prevent and repair skin damage.
  • Novel cosmeceuticals, including anti-inflammatory agents and immunostimulants, show promise for anti-aging.
  • A combination of approaches is needed to address the multifactorial nature of skin aging.

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,...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
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...
Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

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.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
