Written in front: Hi, hi everyone, after the long vacation, are you happy? I really took a good rest during this holiday (travel atypical vlog will be issued on Weibo). Amanda talked about the misunderstood and underestimated ingredients today. Silicone is an ingredient that I often let everyone avoid when buying skin care products, but today I ’m going to hit my own face. I want to give you a complete picture of the real silicone, which is a common name under the dimethylsiloxane composition. So in our article today we will answer:


1 What is dimethylsiloxane?


2 skin benefits of dimethylsiloxane


3 Side Effects of Dimethicone


4How to use Dimethicone


5What are the recommended products?


The velvety smooth texture can be felt in the body milk or moisturizer we often use. The silky texture of most products on the market is contributed by the ingredient of silicone (one of dimethylsiloxane). . But when we hear this ingredient, the impression is always not so positive. A little search will reveal that many people vomit on the Internet. It can clog pores and cause acne, but what is the truth?




What is dimethylsiloxane?




Dimethicone or polydimethylsiloxane (PDMS) is a synthetic polymer of silicon (a natural element of the earth) and an emollient that improves the skin by sealing the space between the dead skin cells of the cuticle. Softness. Dimethicone does not mix with sebum (oily substance on the skin), and we often find this ingredient in facial products such as face creams, lotions, moisturizers, and makeup milks.


Ingredient Type: Emollient.


Main skin care effect: Give the product a silky texture, seal and moisturize, and protect the skin.


Suitable for: It is safe for people of all ages. It is recommended to Uniquer with dry, rough skin and easy peeling.


Best Use: Daily.


It works best with these ingredients: moisturizers and active ingredients that dry and irritate the skin.


Do not use with these ingredients: Polydimethylsiloxane is suitable for most, if not all, other ingredients. So there is no clear contraindication to the use of ingredients.




What are the skin care benefits of dimethylsiloxane?




Overall, dimethylsiloxane can improve the feel, shelf life, and even efficacy of other ingredients in skin care products. In detail, it can be expressed as:


Creating a silky texture: The main reason why silicone (including polydimethylsiloxane) is used in skin care products is that it can make the product experience more pleasant. Make the experience feel more silky and smooth, make the product light, non-greasy, and can be pushed away quickly.


Sealing, moisturizing and hydrating: Dimethicone is occlusive, which means that it can form a waterproof film on the skin to achieve a sealing and moisturizing effect and prevent external irritation and pollutants from invading the skin surface. It forms a barrier on the skin and prevents percutaneous moisture loss. (This is also a feature of silicones that are often misunderstood and criticized.)


Does not cause acne: Although it is occlusive, polydimethylsiloxane is a non-comedogenic component. It is usually an oil-free formula that provides long-lasting hydration but does not clog pores. But most products on the market can cause irritation not because of this ingredient, but because this ingredient is together with other ingredients or directly other ingredients.


Oil control: This ingredient is often used in facial products, especially cosmetics. It can evaporate sweat and control the luster of oily skin so as not to form a large oil field.


Improve the absorption efficiency of the product: It can help seal the skin's moisture, and in the process can make other ingredients in the product more effective.


Skin protection: It acts as a skin protection ingredient against external moisture and irritants that can cause contact dermatitis.


Improve skin texture: Another wonder of this ingredient is that it can diminish fine lines on the face and give the skin a smooth and soft texture, which is why it often appears in makeup milk.


Emollient: As an emollient, polydimethylsiloxane can soften and soothe the skin, and is lighter and non-greasy than other similar ingredients.




Side Effects of Dimethicone




Because this is an occlusive ingredient, whether it causes clogging and irritation of pores and prevents other ingredients from being absorbed into the skin has been a subject of controversy. The truth is that silicone is a non-comedogenic and non-allergenic component. You can even consider them 'cleaner' because dimethylsiloxanes are purely synthetic. Vegetable oils and butters can actually be very complex in composition, are squeezed from plants and are more likely to contain potential allergens.


In addition, it does have a blocking effect, but this is actually a basic function of a moisturizer, and it is not as scary as ‘sticking a plastic film to your face’.


Polymethylsiloxane has actually been included in the FDA's patent for skin protection drug products (I know this breaks my knowledge, but we are constantly evolving and upgrading our knowledge along the way). But for any one of the ingredients, Amanda recommends that you do a skin test first and confirm that there are no overreactions in use.




How to use and items worth buying


In general, this ingredient is safe for daily use, but the frequency and order in which products containing polydimethylsiloxane are used depends on the specific product itself. If it's a moisturizer or makeup primer, it's best to apply it to clean and wet skin after bathing. In order to maximize his occlusive characteristics, you can use water-based essence and gel before using this ingredient, and then use a lotion or cream to lock in moisture.
