Hanoi has just ended a hot and dry spell, hopefully tonight the weather will cool down and be milder than hic hic. In the recent period, my skin must be said to be in a crisis because of acne
Acne has grown continuously on my forehead, cheeks, and chin.. the most since I was in high school until now. So I was in a state of extreme stress.

Needless to say, we all immediately think of creams Neutrogena Hydro Boost Water Gel or Laneige Water Sleeping Mask Last step of moisturizing!! But when it comes to Neutrogena Hydro Boost Water Gel hey, we’ll have to talk about Dimethiconethe ingredient that makes up a huge part of Neutrogena Hydro Boost.

So, I want to answer a bit of the question “Dimethicone in cosmetics clogs pores and causes acne, especially hidden acne.”

First, let’s go through the “boring” scientific information about Dimethicone!

What is Dimethicone?

Dimethicone – scientific name is Polydimethylsiloxane (PDMS) – is a form of polymer group compound, commonly known as Silicone, belonging to liquid silicone group (Silicone Oil). Because it is a macromolecular compound, it has a large molecular structure made up of many small units linked together. To put it simply, it is a form of liquid silicone, which is artificially prepared in a laboratory for use in medicine (contact lenses, medical devices, etc.) to other personal care products (cosmetics). food…) and even in food.

Dimethicone chemical molecular form

Dimethicone acts as an anti-foam, protects the skin, softens the skin/hair, and moisturizes by preventing water loss by forming a barrier to prevent penetration on the skin. Since Dimethicone is a liquid silicone, it spreads easily on the surface when applied. Along with the softening effect, when used in Lotion or cream, it will make the user feel smooth, Dimethicone also creates a special shine, bringing a smooth feeling to the skin. At the same time, by acting as a lightweight water repellent by forming a barrier on the skin’s surface and able to fill in facial lines and wrinkles, Dimethicone can provide temporary plumping and smoothing to the skin. face.

Identifying ingredients Dimethicone, or silicone-based ingredients in cosmetics is very simple, through the way of distinguishing according to the chemical base of the name. However, due to the continuous development of beauty technology, the application of other extracts and new polymer compounds in cosmetics also develops. You can find some polymer components with similar features with names such as:

Uses of Dimethicone

Dimethicone is an ingredient found to soothe and protect the skin for irritant contact dermatitis (ICD) caused by sodium lauryl sulfate (SLS). Numerous tests have demonstrated the effectiveness of dimethicone in the treatment of contact dermatitis and the use of Dimethicone as a protective upper barrier against skin infections.

In addition, Dimethicone also works to reduce redness caused by Rosacea and can be considered an anti-inflammatory agent. For this reason, Dimethicone is included in Sunscreens to form a protective film that protects the skin from irritation with UV absorbers such as titanium oxide and zinc oxide.

Besides, Silicone/Dimithicone is an effective moisturizing ingredient for dehydrated skin by forming a thin film covering the skin surface, slowing down the evaporation of water on the skin surface. Keeps skin moist for longer. Dimethicone’s skin protective film can be maintained continuously for 24-48 hours, which makes cosmetic companies can confidently advertise the moisturizing ability of creams up to 24 hours, such as: Neutrogena Hydro Boost Water Gel.

Above all, the cosmetic industry values ​​this ingredient for its ability to keep skin adequately lubricated, even in the driest and harshest winter weather. As a non-comedogenic ingredient, it provides a significant amount of suppleness and coverage, with a very light texture, not heavy on the face, giving customers a good experience and positive feedback. This, along with the fact that it can enhance the light reflectivity of other ingredients, makes it an excellent candidate for both powder and sunscreen.

Is dimethicone safe?

In general, Dimethicone is rated as a safe ingredient at Level 3 (according to Skin Deep), is not a carcinogen, or affects fertility, does not cause irritation. The FDA allows the use of Dimethicone as a skin protectant in over-the-counter products, and the Cosmetic Ingredient Review (CIR) has rated Dimethicone as safe for use in personal care products. However, according to the Canadian government, some silicone compounds can affect the environment and the ecosystem during both use and product preparation because they cannot biodegrade in nature. (details here).

Along with other common moisturizing ingredients like petrolatum, beeswax, oils, lanolins, silicones/dimethicones are the ingredients with the lowest pore-clogging potential so they are safe for even acne-prone skin. But due to the properties of Silicone/Dimethicone to prevent water from escaping, and at the same time to prevent environmental agents from entering the skin, the use of Silicone/Dimethicone needs to be very careful about cleaning the skin!

Is it true that Dimethicone causes hidden acne?

By skimming the feedback on forums, websites and social networks, the percentage of users of Dimethicone-containing products responds to causing more acne or hidden acne about 3-5%. I don’t make detailed statistics, just count on the pages I often refer to and the websites of companies. However, the cause of this skin condition is not difficult to explain:

Dimethicone ensures that the surface of the skin is covered with a protective layer, plus this protective film is advertised as very “durable”, and “waterproof”, so it is used with makeup and proud setting sprays. for durability and anti-sweating. With summer in hot and humid climate like in Vietnam, this protective film can bring unexpected side-effects to sensitive and acne-prone skin, because it is difficult for the skin to excrete sebum to the outside. Dimethicone Helps lock in moisture to the skin, while also locking in oil, sebum, and other impurities. That means people with acne prone or oily skin will see an increase in blackheads and acne when using products containing this ingredient.

However, acne does not occur in everyone, including those with combination or oily skin. Myself and a few of my friends when using a skin cream containing Dimethicone to have good feedback and effects, especially in the summer, the cream is light, moisturizing, feels soft, smooth, and very shiny. satisfied.

In my personal opinion, Silicone/Dimethicone is a compound that creates a physical protective outer layer for the skin. Silicone/Dimethicone itself, unlike other humectants such as Lanolin, Beewax or vegetable oils, has nutrients, vitamins and lipids that help promote the health of the skin’s natural protective barrier, so total dependence The long-term skin care process into a cream with a majority of ingredients being Silicone/Dimethicone will not bring about the expected effect of a skin care product.
