Effects of dimethiconol on skin

Cosmetic ingredients that are often seen even though they are not in the news

The ingredient is dimethiconol.
You may not be familiar with the term, but it is actually commonly used in skin care and hair care.

It's not talked about as much as beauty ingredients like Vitamin C or CICA .
But why is it included in so many cosmetics?

In this article, we will explain why dimethiconol, a type of silicone, is used in cosmetics and what precautions should be taken.

Silicones: Why you should choose silicone-free skincare

What is Dimethiconol?

Dimethiconol is a silicone used in cosmetics, hair care, and body care products. It is a synthetic polymer with a chain-like structure called siloxane.

It has a slightly sticky paste-like consistency, and when added to cosmetics it gives a soft, slightly sticky texture.
However, when applied to the skin or hair, it feels thick and very light.

Silicones include related ingredients such as dimethicone and siloxane , which create watery textures such as gel creams and hair oils.
However, even though it is called dimethicone, there are many different types, ranging from a watery liquid to a thick paste.

Different silicones are used depending on the feel you want to create.

Why is dimethiconol often used?

The inclusion of dimethiconol makes the product feel light when applied to the skin or hair. It also leaves the skin and hair feeling silky smooth after application.

That's why it's often used in cosmetics that are light and non-sticky.
Here are some other useful points:

Locks in moisture

Like other silicones, it coats the surface of skin and hair, preventing moisture from evaporating.

Protects the skin

Dimethiconol creates a water-repellent film on the surface of skin and hair, essentially an artificial barrier.
This protects the skin from external allergens and pollutants, and the film also gives the skin firmness, which may help reduce the appearance of fine lines and pores.

Makes hair smooth

When used for hair care, it gives hair shine and makes it smooth. It also helps prevent tangling and improves hair manageability.
It also protects hair from heat damage, which is why it's often included in conditioners and hair oils.

People with acne-prone or oily skin should be careful

As mentioned above, dimethiconol creates a barrier on the skin that protects it from external aggressors.

On the other hand, if harmful bacteria, sweat, dead skin cells, or dirt remain on the surface of the skin, they will remain in contact with the skin for a long time.
This can result in worsening inflammation and acne.

This artificial barrier repels both water and oil. It is sweat-resistant and does not easily come off, so it is great for foundation and other makeup-related products.

On the flip side, it can be difficult to remove even with cleansing , and any residue left behind can lead to sticky skin and rough skin.

Also, be careful as it can easily remain in your hair.

When using hair care products that contain silicones such as dimethiconol, it is important to remember to rinse thoroughly. If silicones remain on your hair, they can make it feel heavy and sticky.

Safety of Dimethiconol

Like other silicones, dimethiconol is non-irritating and safe for the skin , is not absorbed through the skin, and has no reported risk of carcinogenesis or reproductive impairment.

Unless you have a sensitivity or allergy to silicone, dimethiconol itself is unlikely to cause skin problems, even if you have sensitive skin.
