What are pre and probiotics?
Usually obtained from sugars in some plants (bananas, onions, garlic, and certain cereals like barley are rich in prebiotics), prebiotics are essentially 'food' for the beneficial bacteria that inhabit our bodies and the skin's surface. They help balance the microbiota, strengthen the skin barrier protecting against potential pathogens and moisture loss, and have anti-inflammatory, soothing, and healing properties, making them beneficial for acne, dermatitis, and eczema. Additionally, they stimulate collagen production, providing elasticity, density, and firmness to the skin.
Unlike prebiotics, probiotics are living microorganisms. Found in yogurt, kefir, kimchi, as well as in other fermented foods or beverages like kombucha, they are essential for overall health and help balance the skin from within. Applied to the skin, they provide additional support to the existing beneficial bacteria, contributing to a more effective protective barrier, neutralizing the action of pathogens, and helping the skin deal with dehydration. Moreover, they are able to restore the skin and calm inflammation, making them ideal for those with irritated, reactive, or sensitive skin.
However, incorporating live probiotics into skincare products is not easy, mostly in terms of stability, preservation, and shelf-life. Therefore, you will usually find them in the form of lysates, which are produced by breaking down the cell walls of probiotic bacteria (or some yeasts) and extracting their beneficial assets such as proteins, peptides, enzymes, and other compounds. For this reason, they are often referred to as post-biotics. They provide the benefits of probiotics without the risk of adverse reactions.
Because both prebiotics and probiotics act to maintain a healthy microbiota, using both in a single formula, as in our Pre and Probiotic Booster, can yield significant benefits.
