Summary
Topical cosmeceuticals, including botanicals, peptides, and hydroquinone, effectively treat skin damage from UV radiation. Peptides show the strongest evidence base for improving photoaged skin.
Area of Science:
- Dermatology
- Cosmetic Science
- Photodermatology
Background:
- Photoaging is skin damage caused by ultraviolet (UV) radiation.
- Topical cosmeceuticals are frequently used to address photoaging.
- Understanding the efficacy and evidence for these treatments is crucial.
Purpose of the Study:
- To systematically review and compare the efficacy of common topical cosmeceuticals for treating photodamaged skin.
- To assess the level of scientific evidence supporting these treatments.
- To evaluate botanicals, peptides, and hydroquinone for photoaging treatment.
Main Methods:
- Systematic review of scientific literature.
- Searched databases (OVID, PubMed, MEDLINE) for studies on photoaging treatments.
- Included keywords: Photoaging, Azelaic acid, Soy, Green Tea, Chamomile, Ginkgo, Tea Tree Oil, Resveratrol, Cucumber, Ginseng, Centella asiatica, Licorice Root, Aloe Vera, Peptides, Argireline, Hydroquinone.
Main Results:
- The majority of evidence for cosmeceuticals is high-quality (Level I-II).
- Peptides demonstrate the most robust evidence base.
- Many studies on peptides achieved Level Ib evidence status.
Conclusions:
- Topical cosmeceuticals, specifically botanicals, peptides, and hydroquinone, are effective in treating photodamaged skin.
- The evidence supports the use of these agents in cosmetic medicine.
- Peptides offer a strong therapeutic option for photoaging.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
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...

01:12Renewal of Skin Epidermal Stem Cells
2.5K
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...

13.1K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

11.5K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

3.6K
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...

01:19The Effect of Aging on Tissues
2.1K
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...
