The skin, the body’s largest organ, is a complex structure composed of three layers: the epidermis, dermis and subcutaneous fatty layer. Among these, the epidermis is further divided into distinct layers including the stratum corneum (SC), which serves as the primary line of defence for the body.
Imagine the SC as a wall made of tightly packed bricks, with each brick represented by corneocytes. These corneocytes are bound together by mortar-like lipids such as ceramides, cholesterol and fatty acids. Additionally, a crucial protein known as filaggrin aids in creating natural moisturising factors (NMF) vital for skin health.
The skin barrier fulfils a multitude of functions
The skin barrier fulfils a multitude of functions, acting as a shield against pollution, UV rays, chemicals, mechanical stress, irritation, inflammation and infections. It also regulates the loss of water from within, ensuring the skin retains its moisture content, keeping it adequately hydrated.
Numerous skincare products are specially formulated to either preserve or restore the SC to its optimal condition, safeguarding it from external factors that could compromise its integrity. Key measurable parameters indicating suboptimal SC function encompass skin hydration (indicative of dehydration), erythema (manifesting as skin redness) and Transepidermal Water Loss (TEWL).
Objective skin measurement tools play a crucial role in evaluating alterations occurring within the skin. These studies are designed to deepen our comprehension of the diverse influences and impacts on this vital organ. Some raw materials may exert no influence on the barrier, while others may exhibit positive or negative effects. The goal is to enact positive changes, enhancing hydration levels, reducing TEWL and mitigating erythema.
How to improve skin barrier function
Improving skin barrier function can be accomplished through various approaches, with a selection of materials available at different price points, each offering distinct benefits. Noteworthy among these is Wagandys, a blend of Squalane, Phytosterols and an array of plant oils and extracts rooted in Ayurvedic science. This potent combination not only restores the barrier function but also augments hydration while visibly diminishing the appearance of wrinkles and fine lines.
What is Sensia Carota, MagnuteSe Sense Oil and Makigreen Rice Oil?
Sensia Carota is primarily designed for sensitive skin, working to pacify inflammation and erythema. Its notable effect on reducing TEWL not only shields the skin’s deeper layers but also rebalances the skin microbiome. MagnutSe Sense Oil and Makigreen Rice Oil are two additional oils deserving special mention. They play a significant role in moisturisation, replenishing skin lipids and conditioning the skin. Additionally, they counteract inflammation and contribute to the restoration of the barrier function.
Understanding the pivotal role of the skin barrier is imperative for maintaining healthy, radiant skin. The stratum corneum, fortified by essential lipids and proteins, serves as a fortress against environmental aggressors. By carefully selecting skincare products enriched with materials that enhance barrier function, we can fortify our skin’s resilience and vitality. Embracing these insights empowers individuals to make informed choices in their skincare regimen, ensuring the preservation of this vital protective barrier.
