Importance of Skin Barrier

Hi my loves!!

Today it’s all about skin. These anatomical barriers include the skin, mucous membranes and bony encasements. But let’s not get too technical shall we?

In simple terms, the skin is the primary barrier for bacterial entry into our body. The epithelium is the first layer we encounter as it is the topmost and visible layer that covers our entire body followed by the dermis. The skin, comprising of both epidermis and dermis layer, is dry, acidic and has lower temperature all of which is not favourable for bacterial growth.

A process of dead cell accumulation called keratinization occurs periodically to slough off the dead skin as well as dirt from the epidermis making it more difficult for bacterial growth to happen. Hair follicles and sweat glands produce toxic enzymes and lipids that destroy evading bacteria and those that escape these barriers are often eliminated by our resident normal microbiota. Despite tight security, it is undeniable that some of these sneaky pests manage to get under our skin.

Mucus and connective tissue makes up the mucosal membrane which lines the body cavities that are directly exposed to the exterior. The mucus is a physical barrier that traps microbes. Mucus also contains lysozyme to degrade bacteria and an antibody that prevents microbes from attaching to mucosal cells and traps them in the mucous. Ever wondered where those whiteheads come from?

Whiteheads are the result of the lysozyme and antibody action on the microbes and the death of these cells come together to form pus that presents itself as whiteheads. Thank your skin guys!! It means you have a good immune system going on. Funny things aside, the skin barrier is an important factor in maintaining a clean and healthy skin.

That is also why exfoliation is a good practice to remove the dead skin and inhibit bacterial growth. However, over-exfoliation can lead to the disruption of the acid mantle. This compromises the skin barrier and allows for easier bacterial colonization and sensitivity. Be warned guys! Question is how to get around this? I have spoken about the benefits of incorporating an oil to your beauty routine previously and let’s dive deeper into the science of it this time.

The LUXE beauty oil is made up of squalane. Squalane is the processed, stable derivative of squalene. This is done to ensure a longer shelf life of the product and maximum usage by a consumer. Squalene is usually found in human sebum or in shark liver. Due to commercialization, now squalene are lab produced, processed and marketed without harming any sharks or the environment. Squalane is an emollient, comes in a form of greasy oil that helps lubricate and soften the skin. It forms a protective layer that minimalizes water loss from the skin. Beauty oils are favourable in those with dry skin and can be used by all skin types during the day to prevent water loss. The summer heat, humidity and dry AC wind often accelerates water loss from the epidermis. The lack of water consumption in cold working environments also synergizes water draining from the skin; making the LUXE beauty oil suitable for college students as well as working women.

Enriched with grapefruit and prickly pear, it brims with Vitamin E and antioxidants making it suitable for use in mature skin as well. Layer it after a good a good spritz from Orgga’s Rose Otto and before your sunscreen.

Till the next ladies, this is me signing off!
