Summary
Infant skin barrier is immature, making it vulnerable. Proper skincare from birth is crucial for preventing infections and atopic diseases like dermatitis.
Area of Science:
- Dermatology
- Neonatal Care
- Pediatrics
Background:
- Neonatal and infant skin exhibits distinct structural and functional properties compared to adult skin.
- Immature skin barrier in early life increases vulnerability to environmental factors, infections, and dehydration.
- Skin pH undergoes significant changes in neonates and infants, impacting barrier integrity.
Purpose of the Study:
- To review the characteristics of skin barrier function in neonates and infants.
- To explore the relationship between skin barrier development and the onset of atopic dermatitis.
- To provide recommendations for appropriate skincare in early life.
Main Methods:
- Literature review focusing on skin barrier function in neonates and infants.
- Analysis of structural and functional differences in early-life skin.
- Examination of pH-related changes and their impact on barrier integrity.
- Review of studies linking skin barrier dysfunction to atopic dermatitis.
- Synthesis of current recommendations for infant skincare.
Main Results:
- Neonatal and infant skin is thinner, more permeable, and less developed than adult skin.
- Altered skin pH in early life is a key factor affecting barrier function.
- Compromised skin barrier integrity is associated with an increased risk of atopic dermatitis.
- Specific skincare practices are essential for maintaining healthy skin in infants.
Conclusions:
- The unique characteristics of neonatal and infant skin necessitate specialized care.
- Maintaining skin barrier integrity from birth is vital for preventing skin conditions and atopic diseases.
- Adoption of mild, fragrance-free skincare products and tailored regimens is recommended for neonates and infants.

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...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

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...

6.7K
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

01:21Accessory Structures of the Skin: Sebaceous Glands
1.7K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...
