How Tyrosine Used In Skin Care Products

Tyrosine is an amino acid, meaning it is one of the building blocks that make up protein. It is non-essential which means that our body is able to produce it. Most people will normally ingest Tyrosine on a daily basis from various food sources such as diary, fish, meats, eggs, beans, nuts, wheat and oats. It is used in skin care products to introduce amino acids to build, repair or strengthen skin tissue; so, it is widely used in formulations for anti-aging and anti-wrinkle products. It is also helpful in lotions used to introduce and retain moisture and hydration levels.

Despite the body already producing it, it can be found in skin care products as well as supplements and medications to treat various diseases such as PKU (phenylketonuria). When used in skin care products, the added levels will help reduce wrinkles that are related to age and can serve as a moisturizer.

Why It Is Used

Before we understand how Tyrosine works in skin care products, we need to know why it is used in the first place. When used in conjunction with ascorbic acid, it is can help stimulate fibroblasts and as these fibroblasts are involved in collagen production, it can increase a personís collagen levels slowing premature skin aging. Higher collagen levels help to firm your skin and add tone. Additionally, it can also aid in the production of melanin which will assist with the skinís ability to produce colors, giving you a healthy, natural looking tan. As mentioned earlier, it has also been associated with clearing up wrinkles.

How It Is Used

The theory behind using Tyrosine for skin care is that when it is applied topically, it will be able to penetrate the tissue. It will then increase the levels in melanocytes, which are responsible for the formation of melanin. These skin care products will therefore be increasing the amount of melanin in the skin simply by applying a cream that contains it. There is research on its effectiveness that has been mixed and some scientists believe this is because tyrosine has a complex chemical pathway and it is more difficult to access it when applied topically as opposed to ingested. Despite this, many people see results.


Tyrosine is definitely safe to ingest in food as this is a natural function that humans have been following for centuries. Researchers agree that it is also safe in supplement form as well as in topical creams such as skin care products. Because of this, the Food and Drug Administration has approved its use and classified it as safe, allowing it to be used in skin care products without any fear of serious side effects or the development of conditions.


In addition to being found in skin care products, tyrosine is a key ingredient in several supplements that aim to improve alertness and other minor conditions. In terms of skin care products, it can be commonly found in wrinkle cream as mentioned above as well as other anti-aging products such as eye contours and skin tightening creams. It can also be found in sunscreens (both ones included within concealers and other face products and some of those with high SPFs or that contain moisturizers), face moisturizers, exfoliants, concealers to help firm the eyes and even after-shaves.
