Who would have thought that not only fermented food that could benefit our gut's health but also fermented skincare for our skin? Fermented skincare products are not just the ordinary short-lived skincare trend; their continuous existence has proved it even after years since the trend started. It means something, right? We are about to reveal all about the goodness of fermented skincare products and what they can bring to your skincare routine.
What is fermentation?
Fermentation is a metabolic process where a microorganism's natural enzyme breaks down molecules, such as sugar, to other new substances. Fermentation has been widely used in the food industry for so many years to create our all-time favourite food or drinks such as wine, yoghurt, Kombucha, or Kimchi. Fermented food that we consume can benefit the gut flora and increase the absorption of nutrients to our body. For a long time, Korea has benefited from this fermentation process to preserve their cabbage during the wintertime and create their phenomenal dish, Kimchi. Their love for fermentation doesn't stop there; they started to use this technique in the beauty industry, where they found that it can bring additional benefits to our skin.
What are the benefits of fermentation in skincare?
Improves the absorption of skincare
As you may already know, one of the biggest hindrances for a skincare product with a large molecular size is to absorb deep enough into our skin to be able to do its job. However, the fermentation process can break down larger sized molecules, which are not easily absorbed, into smaller pieces. The smaller molecular size can aid in absorbing the active ingredients and delivering the skin-benefiting properties to our skin.
Formation of new skin-benefiting ingredients
Fermentation does not only break down larger molecular size ingredients into smaller pieces; their by-products can at times create new substances that are beneficial for our skin. Examples of new products made from fermentation are AHA (alpha-hydroxy acids), amino acids, and antioxidants. These by-products contribute to the list of skin-benefiting properties of the raw ingredient itself.
Reduce the chance of irritation
Sometimes, some chemical compounds in a specific extract can be irritating for the particular skin type, especially if you have sensitive skin. However, fermentation can break down this irritating compound and makes the extract more beneficial and less irritating than it originally is.
However, the process of fermentation itself is a general term, and its benefits cannot be generalised for all kinds of ingredients. Some fermented ingredients such as Soy as well as Red ginseng have been scientifically proven to be extra beneficial compared to their non-fermented counterparts.
Fermented Soy can boost the production of Hyaluronic Acid on our skin, while Red Ginseng has been shown to be more beneficial in the improvement of fine lines and dark spots on ageing skin when fermented.
