Summary
Acne vulgaris, a common skin condition, often involves impaired skin barrier function. This review highlights skin barrier repair as a key strategy for improved acne management and reduced patient burden.
Area of Science:
- Dermatology
- Pathophysiology
- Skin Health
Background:
- Acne vulgaris is a prevalent, chronic inflammatory skin disease affecting the pilosebaceous unit.
- It manifests with comedones, papules, pustules, cysts, and nodules, primarily on the face.
- Acne development is multifactorial, influenced by genetics, environment, and lifestyle.
Purpose of the Study:
- To explore skin barrier impairment mechanisms in acne vulgaris.
- To discuss strategies for skin barrier repair in acne management.
- To offer novel perspectives for clinical treatment of acne.
Main Methods:
- Review of existing literature on acne pathogenesis and skin barrier function.
- Analysis of factors contributing to skin barrier dysfunction in acne.
- Synthesis of current and emerging therapeutic approaches focusing on skin barrier repair.
Main Results:
- Acne vulgaris pathogenesis involves sebaceous gland hyperplasia, abnormal keratinization, microbial factors, and inflammation.
- Skin barrier impairment is a significant, often overlooked, aspect of acne.
- Current treatments inadequately address skin barrier repair, leading to suboptimal outcomes.
Conclusions:
- Repairing the skin barrier is crucial for effective acne vulgaris treatment.
- Integrating barrier repair strategies may improve treatment efficacy and reduce recurrence.
- A shift in focus towards skin barrier health offers new therapeutic avenues for acne.

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

01:24Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
356
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.

280
Peptic Ulcer Disease (PUD) is characterized by the development of ulcers in the stomach or duodenal mucosa. Its pathophysiology is complex, involving a balance between damaging and protective elements.
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

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...

01:26Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

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...
