Chitosan: What is it and Why Does Your Skin Need it?

Have you ever wondered what you are actually applying to your skin? Yes, that cream you have bought is advertised to have, for example, a moisturizing effect, but, have you ever wondered why?

Yes, well, most people don’t.

People usually buy products without reading the label. And even when they read it, they can hardly understand what it says, because it is full of some ingredients you cannot read out properly, let alone understand what they mean.

However, in recent years, the tide has shifted. Here at Introstem, we’ve been happy to see many consumers starting to pay more attention to the products that they buy, namely, whether the products are devoid of any cancerous ingredients or if they are tested on animals.

A fortuitous turn of events, especially for the animals, you will agree. (Don’t worry, all of the products that you’ll find at Introstem have definitely not been tested on animals!

In order to help you and make the label readable, we are going to present to you one of the most desired and most effective ingredients any skin care product should have, their majesty – chitosan.

What is Chitosan?


To put it simply, chitosan is a derivative from Chitin. Unless you are in the pharmaceutical industry, we are quite certain this means nothing to you, so let’s explain further. Chitin is an ingredient that is usually isolated from the outer shell of crustaceans, such as lobster, crab and shrimp.

However, if you are concerned with animal safety, don’t fret, because it can also be isolated from some fungi. So, if you only buy vegan skincare products, there are plenty of options that contain chitosan and that are vegan, too.

The only difference between Chitin and Chitosan is that the former cannot be dissolved in a liquid and the latter can. That way it can be included in different skincare products.

One could wonder how on earth someone could actually think of putting such an ingredient in a skincare product. Well, the benefits of chitosan have been known for decades now. And, honestly, due to its numerous health benefits, it is understandable how it ended up in moisturizers.

Salvation for Your Skin

There are so many things that can affect the state of your skin. In order to solve each and every one of them, you would need to buy a whole bunch of different products, which is not so affordable, now is it?

Then, why not buy only a couple of good ones that will have one omnipotent ingredient, whose use has such a wide range of benefits, it could solve all your skin problems at once? The benefits chitosan has on your skin are numerous, so let’s not waste any more of your time.

It Moisturizes the Skin

As we said, there are so many factors that influence your skin, so you would need a really strong product to help it thrive instead of losing its glow. Many things also influence the dryness of your skin, including air pollution, dry weather, air conditioning, hot water, some medications, some skincare products, and, of course, individual properties of the skin itself.

Only those with dry skin can understand the struggle, the pain of the cracked surfaces and the constant feeling of itchiness. Now all that suffering can come to an end with the use of chitosan.

One of its main features is to serve as a barrier, in this case, the barrier between the outer world and the surface of your skin, thus preventing water loss. Dry skin lacks the ability to create enough of that layer which is responsible for water retention. That is why all the people with dry skin need to use a proper moisturizer, and they need to do it often.

After a chitosan-based moisturizer is applied on the skin, it serves as a protective layer which locks the moisture in, enabling your skin to get a much healthier and fresher look.

It Has Anti-Aging Properties

If the aforementioned positives didn’t help you see all the benefits chitosan-based skincare products could have, this one will certainly seal the deal.

Although aging is a natural process, it is often sped up by a number of different factors which, among others, include smoking, UV radiation, air pollution, etc. Those with drier skin are in an even bigger of a pickle, because it is proven that dry skin ages faster due to the loss in elasticity.

When the skin is dry, it loses the necessary water, which is responsible for nourishing the skin cells, leading to skin cracking, creating fine lines and wrinkles sooner than one might expect. That is why it is essential for people with dry skin to moisturize properly and not skip their skin routines.

By preventing water loss, chitosan increases skin elasticity and smoothness, enabling you to have a perfect-looking face without a single line for years to come. What else could you possibly ask for?

Moreover, it promotes skin cell regeneration, which is yet another process that dwindles away as you get older. Your skin becomes rougher and duller because of that. As it has been mentioned, chitosan has amazing regenerative properties, so it comes as no surprise that it is an ingredient that can be found in many anti-aging products.

To add to your anti-aging skincare collection, check out some of Introstem’s products that are designed to smooth away fine lines and wrinkles.

It Cleans the Skin

Its strong antimicrobial properties are applicable in many forms especially when applied to the skin. Those with severe cases of acne can benefit significantly from chitosan in many ways.

As you know, a wide range of inflammation occurs on and in the skin due to bacteria, acne being one of the hardest and most persistent ones to handle. They usually happen when the skin is creating extra sebum which is clogging the pores, creating a fertile ground for bacteria to flourish and cause inflammations of different kinds.

When this happens, a proper cleanser, such as the Introstem Stem Cell Mousse Cleanser, needs to be used in order to solve the problem. Due to its incredible antimicrobial properties, chitosan has proven to be the most valuable ingredient of many skin products.

Exfoliating takes a high number one on the scale, when it comes to skin cleaning routine, especially for those with acne. Even better if it has chitosan in it. While exfoliating, chitosan serves as a glue that attracts all the dirt and dead cell residue from the pores, allowing them to breathe. Its healing properties remove the bacteria which successfully prevents inflammation processes and infections to arise. Consequently, fewer acne breakouts will happen because of it.

It Protects Your Skin from UV Radiation

If you read the back label, you might notice that most of the sunscreens have chitosan in them. The reason for that is simple – chitosan effectively absorbs UVA and UVB rays, which are the main cause for rapid skin cell deterioration, not to mention that they are one of the main causes of skin cancer.

Research shows that sun protection products that have chitosan in them are up to 200% more effective in absorbing the harmful sun rays than any other product. UVA and UVB rays are one of the main culprits for the speedy aging of your skin, so using chitosan-based products will certainly put a stop to that.

It Helps Other Products

It is unimaginable that you spend absurd amounts of money on a product that will, simply, not work. However, this is what happens if you have a skin problem which you are not treating, while trying to solve another one.

Dead skin residue is one of the main causes why many skin products do not penetrate the deeper layers of the skin, where they are supposed to end up. Excess sebum is one more thing on the list. By creating that extra layer on the skin, excess sebum is actually stopping skincare products from penetrating further.

Chitosan-based products help in these situations, either by being a part of your exfoliation product, or by its antimicrobial effect.

However, there is one more problem many of you encounter without even knowing. Not every antioxidant cream you buy will do its magic, did you know that? Successful distribution of antioxidants into the deeper layer of your skin also depends on the type of ingredients that are used. This means that one mixture of ingredients will not be as effective as the other one. Not every ingredient can help antioxidants go in the deeper layers of the skin.

On the other hand, when antioxidants are combined with chitosan, they are capable of penetrating deep into the skin and having fun there. Even though antioxidants are really hard for the skin to absorb, and there are not many products that can promise you that, chitosan will help those bad boys sink right away, making them that more effective.

A Cure for Your Dental Problems

A lot of research has shown that chitosan is extremely beneficial in treating different dental conditions, due to its bioactivity, as well as anti-inflammatory and wound healing properties.

You’ve got to love science, right?

There is nothing worse than a tooth pulsating in your head, while you are trying your best to reach the dentist, enduring enormous amounts of pain and discomfort. You would take it out yourself if you could, only to stop the agony you are going through.

However, this is best left to the experts to solve.

And the experts have come to a conclusion, that when it comes to curing an inflammation in your mouth, or treating the cavity that is left after a teeth extraction, there is nothing better than using a chitosan-based product. It has been proven that chitosan influences the reduction of pain and the recovery time, because it creates a specific barrier which protects the surface of the wound.

It Works Wonders on Your Hair

Well, now you can have it!

Just look for the hair care products, whether they are conditioners, shampoos or hair masks that have chitosan in it, and you are good to go!

Remember the aforementioned fact that chitosan comes from the shell of some crustaceans? If you read about crustaceans in a biology book, you can easily find out that they have an amazing power of regeneration. Look at, for example, sea stars. When they lose a limb, they soon grow another one, thanks to none other than chitosan.

Imagine the wonders it can do with your hair!

All the hair products which have chitosan in them have the power to regenerate damaged hair. It protects each and every strand by creating a protective layer around them, making it impossible or very hard for them to break. In addition, it stimulates hair growth and gives it the necessary elasticity to endure all weather conditions, and all the outer irritants which might affect it.

Chitosan helps with increasing hair thickness and improvement of all the other properties which make your hair softer and shinier than ever.

Isn’t that what every person seeks? One good hair day, which would make up for all the stressful situations you had to go through?

We know that, at this point, you are already at the door, ready to rush to the nearest drugstore. But wait just now, we have just started elaborating on how amazing this ingredient really is.

It Helps With Weight Loss

You have to remember that there is no magical cure for losing weight. You have to make a serious effort if you want to succeed. However, there is no harm in getting some additional help from a dietary supplement now and then. And a chitosan-based one might just be the right choice. Some studies have shown that it has a beneficial effect on your weight loss, because it blocks the absorption of fat, which speeds up the process of achieving your goal weight.

Furthermore, it has also been proven to reduce the levels of cholesterol, which can be a possible solution to many heart problems one can have because of it.

However, it has to be noted that each dietary supplement you take has to be approved by a doctor. You shouldn’t take anything on your own, because only your designated physician can know the real state your body is in, and whether you would benefit from such a supplement. 

If all the reasons stated above don’t make you go to the store and buy whatever skincare product they have that has chitosan in it, we don’t know what will.
