The Power of Yeast Protein

Hydrolyzed Yeast Protein may not be a household skincare name yet but there’s a good chance you’re already using it. Found in many skin and hair-conditioning products, this hard-working antioxidant has the power to brighten skin and protect it against the harmful effects of environmental aggressors. Here, we take a deeper dive into the makeup of this multitasker to unravel all its complexion-enhancing benefits.


Hydrolyzed Yeast Protein, also known as yeast extract, is derived from an acidic or enzymatic hydrolysis process. Simply put, hydrolysis is the process in which a water molecule is added to a substance in order to rupture the chemical bond.

Hydrolyzed Yeast Protein is created through this method and is then infused into beauty products. It contains a unique mixture of flavonoids, sugars, vitamins, and amino acids which allow it to function as a multi-tasking conditioning agent.


Hydrolyzed Yeast Protein is a true multi-tasker. Firstly, it contains essential amino acids and small peptides which work to brighten the skin by targeting melanocytes. Melanocytes are the cells that produce melanin, the pigment that gives our skin and hair its colour. However, as we age, melanocytes can begin to overproduce pigments which leads to dark spots.
Yeast also contains sugars that are naturally converted into acids. These acids work as antioxidants and protect the skin against various forms of environmental damage. According to The Derm Review, a yeast sugar named beta glucan has been shown to “stimulate Langerhans cells, which are immune cells just below the skin’s surface that help protect us from environmental skin damage and reactions.”

For those of you seeking anti-ageing benefits, these naturally synthesized acids are also believed to stimulate collagen production.


Chances are you could already be using Hydrolyzed Yeast Protein in some form or another. In haircare, Hydrolyzed Yeast Protein is often found in conditioner and works to make hair more manageable. It conditions the strands in order to make them easier to comb and softer to touch while adding shine and volume.

In skincare, the topical application of Hydrolyzed Yeast Protein is known to improve the skin’s condition. Its soothing and moisturizing properties play a part in maintaining the quality and appearance of skin for a brighter looking complexion.


When starting out, an important step in understanding Hydrolyzed Yeast Protein is knowing where to find it on the ingredients list. Yeast Extract often appears listed as Faex Extract. It has the ability to increase cell turnover and improve collagen synthesis, so it’s often found in products that promise anti-ageing and reparative benefits.


Due to Hyrdrolyzed Yeast Extract’s softening and conditioning functions, it’s most effective when it’s infused into products that you leave on your skin. This includes formulas such as creams, overnight serums, toners or boosters.

When left to work on the skin, Hyrdrolyzed Yeast Extract helps maintain the skin’s overall quality and appearance. Alongside it’s moisturizing and soothing properties, it also has the ability to brightening skin, leaving your complexion looking and feeling illuminated.
