Summary
Skin lipids, including ceramides and fatty acids, are vital for a healthy skin barrier. Their composition is influenced by various factors, impacting skin health and requiring further research into their role with the skin microbiome.
Area of Science:
- Dermatology
- Biochemistry
- Microbiology
Background:
- Skin lipids are crucial for barrier function, preventing water loss and protecting against external factors.
- Lipid composition varies with age, diet, and environment, found mainly in the stratum corneum.
- Diverse lipids like ceramides, cholesterol, and fatty acids perform complex roles in skin health.
Purpose of the Study:
- To review the properties and functions of skin lipids, particularly fatty acids.
- To explore the relationship between skin lipids, homeostasis (e.g., pH), and the skin microbiome.
- To understand how daily skincare practices affect skin and microbiome health.
Main Methods:
- Literature review of scientific articles on skin lipids and their functions.
- Analysis of lipid properties, biosynthesis, and interactions with the skin barrier.
- Synthesis of information regarding the influence of external factors and skincare on skin lipids.
Main Results:
- Skin lipids are essential for maintaining skin barrier integrity and hydration.
- Fatty acids play a significant role in skin maintenance and overall homeostasis.
- The interplay between skin lipids and the skin microbiome is complex and requires further investigation.
Conclusions:
- Understanding skin lipid properties is fundamental for dermatology and treating skin conditions.
- Further research is needed to elucidate the impact of the skin microbiome on lipid composition.
- Skincare practices significantly influence skin health and the skin microbiome balance.

Microbial membranes exhibit remarkable diversity in lipid composition, reflecting evolutionary adaptations to various environmental conditions. The three domains of life—Bacteria, Archaea, and Eukarya—synthesize membrane lipids through distinct biosynthetic pathways, leading to fundamental structural differences that impact membrane stability, function, and adaptability.Fatty Acid-Based Lipids in Bacteria and EukaryaBacteria and eukaryotes share a common fatty acid biosynthesis...

Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

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.

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...

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
