In recent years, with the increasing popularity of scientific knowledge, more and more consumers are paying attention to the ingredients in their skincare products. Rather than choosing based on brand or price alone, they now select products based on the specific benefits the ingredients offer. For instance, the “Vitamin C in the morning, Retinol at night” trend is based on the idea of choosing products with certain ingredients for specific skincare effects. Consumers are also becoming more cautious about harmful ingredients in the products they use, such as the much-discussed silicone oil.
But is silicone oil really as harmful as some online discussions suggest?
Silicone oil is a common term, but it’s rarely listed by that name on product ingredient lists. Instead, you’ll find various forms of “siloxanes” (essentially, polysiloxane compounds), such as dimethicone, cyclopentasiloxane, phenyltrimethicone, and many others. There are thousands of different types in the silicone family, and their names can seem long and complex. However, it’s easy to recognize these ingredients; if you see “silane” or “siloxane” in the name, it’s a silicone oil.
Silicone oil itself is a colorless, odorless, and safe chemical compound. Originally used in industrial applications, it was valued for its water, dust, and oil resistance. In 1950, it was first incorporated into cosmetics by an American company to create silicone hand creams. People found that it provided superior moisturizing effects compared to previous products, which led the cosmetic industry to adopt silicone oil. Since then, silicone oil has become a key ingredient in almost all types of cosmetic products.
Take dimethicone, for example. It helps increase the smoothness and silky feel of the skin without leaving a greasy or sticky residue. This excellent skin feel makes silicone oil a game-changer in skincare products, especially because the initial impression of a product is often shaped by how it feels on the skin. Because of this, silicone oil is frequently used in sunscreens to reduce the sticky sensation caused by various sunscreen agents, making the product feel lighter on the skin. It's also commonly found in moisturizers because it forms a protective layer on the skin's surface, locking in moisture without making the skin feel greasy.
Silicone oil is highly water-resistant and can form an even, breathable protective film on the skin that helps maintain smoothness. For example, trimethylsiloxy-silicate is a silicone oil film-forming agent that is commonly added to makeup products, such as lipsticks and foundations, to make the makeup last longer and resist sweating, helping to avoid embarrassing makeup meltdowns.
Silicone oil also acts as a hair conditioner, filling in the gaps between the scales of the hair shaft, forming a protective layer that makes the hair softer, smoother, and shinier. As a result, many shampoos, conditioners, and hair masks contain silicone oil derivatives. However, at some point, online discussions began to demonize silicone oil, blaming it for clogged pores, hair loss, and acne. This led to the emergence of “silicone-free” versions of hair care products.
In reality, silicone oil is unlikely to cause the skin issues some online discussions suggest. Silicone oil is a large molecule, and it typically stays on the surface of the skin, meaning it doesn’t get absorbed into the skin or clog pores. As such, it’s not likely to cause acne or exacerbate skin conditions.
Similarly, claims that silicone oil causes hair loss are unfounded. Hair loss is generally due to factors like genetics, hormones, or lifestyle choices, and is not directly related to the use of silicone oil.
It’s also worth noting that, although most silicone oil derivatives do not irritate the skin and are not absorbed by the body, some forms of silicone oil can irritate the eyes. Therefore, it’s important to be careful and avoid getting products containing silicone oil into your eyes, whether when applying sunscreen, makeup, or shampoo.
Overall, most forms of silicone oil are not irritating to the skin, are not absorbed by the skin or digestive system, and are considered to be non-toxic. However, some cyclic silicones (such as cyclotetrasiloxane, cyclopentasiloxane, and cyclohexasiloxane) have raised concerns due to their potential risks. In Europe, there are restrictions on the use of these compounds, although no such restrictions exist in most other regions, including China. If you're concerned about these potential risks, you can opt to avoid products containing these specific silicones.
In conclusion, silicone oil is a widely used ingredient in cosmetics and skincare products due to its superior skin feel, moisturizing, and water-resistant properties. Despite some online fears, there is no solid evidence to support the idea that silicone oil causes significant harm. When used properly and with attention to ingredient details, silicone oil remains a safe and effective component in many beauty products.
