The world of skincare has recently taken over the beauty industry. Millions have joined in on this trend in the hopes of having clear skin, looking youthful, and learning about the do’s and don’ts of skincare ingredients used in beauty products.
But today, we’ll focus our attention on one specific ingredient that has stormed the skincare world: yeast extract. Recently, yeast extract has become a topic of conversation, as many experts have discovered its hidden skin benefits. And so, in this article, we’ll break down if yeast is actually good for the skin and what specific benefits it may possess.
What is yeast extract?
Before we jump straight into the scientific benefits of yeast extract for the skin, let’s take a look at what yeast extract is. Many of us may be familiar with the food additive – yeast. This single-cell fungus is actually one of the most common ingredients used in the food industry. From all kinds of bread to beer, yeast is a superstar in the world of baking.
But what about yeast extract?
To put it simply, yeast extract is the same as yeast but without the cell wall composition. Yeast extract is used in skincare because it is a rich source of proteins, amino acids, B vitamins, sugar, flavonoids, peptides, and fatty acids needed for healthy skin. Yeast is also a good source of β-glucans, a soluble fiber possessing multiple skin benefits. There are different kinds of yeast extracts found in skincare products, and Saccharomyces cerevisiae is probably the most researched one.
Now you might be wondering how yeast extract can benefit your skin. According to recent studies and research, adding yeast extract to certain beauty products can increase the skin’s antioxidant defense. Thanks to its structural composition, yeast extract can also soothe inflammations, increase moisture retention and lighten the skin. With this in mind, let’s look at yeast extract skin benefits.
Yeast extract has antioxidant properties
One of the benefits of yeast extract for the skin is its high antioxidant activity, attributed to its content of polyphenols. Antioxidants are always welcome since they protect skin cells from the damage caused by the free radicals present in the environment. This defending mechanism of yeast neutralizes free radicals, which in turn keeps the skin healthy.
According to a study from 1998, yeast extract not only activates the body’s defense mechanism but accelerates the wound healing process. More specifically, it was found that β-glucans derived from yeast extract could protect the skin from harmful UV radiation as well as promote the growth of keratinocytes, the primary type of cell found in the outermost layer of the skin. That process is achieved by stopping helpful antioxidant molecules from being depleted.
Yeast extract can increase skin hydration
Another skin benefit of yeast extract is increasing skin moisture. It was found that formulations containing yeast extract had long-term effects on the improvement of skin hydration. Research suggests that the moisture-retention capacity of yeast extract is equivalent to that of glycerin, one of the most effective humectants, a type of moisturizing agent that pulls water into the skin.
Yeast for skin whitening
But the list of impressive benefits doesn’t stop there. You’ll be glad to find out that yeast extract can also be used for skin whitening.
The benefits of yeast for skin whitening include the inhibition of melanin synthesis in the skin cells. According to research, yeast can reduce melanin levels, the pigment that defines skin color (which overproduction leads to skin discolorations), by suppressing tyrosinase expression, an enzyme responsible for melanin production. Based on their findings, the daily intake of 100 mg of the yeast extract for eight weeks resulted in significant skin whitening effects. Besides inhibiting tyrosinase, yeast may also lighten the skin by absorbing UV radiation, preventing sun damage.
Yeast can reduce skin inflammations
The beta-glucans derived from yeast are known to possess multiple benefits, including antioxidant, skin repairing, and anti-inflammatory properties. Due to its soothing effect, yeast extract can be used in skincare to calm the skin, relieve inflammations and reduce redness.
Is yeast good for your skin?
By now, we have seen yeast extract skin benefits as well as how we can use yeast for skin whitening. To answer our initial question – is yeast good for your skin? The answer is – YES! Whether you are looking for a smoother overall skin texture and want to bring back that youthful glow, using skincare products with yeast extract is a great choice.
