The Science of Dimethicone in Skin Care

25 January 2025


The Science of Dimethicone in Skin Care




Dimethicone is a silicone based ingredient that used to be prized for its texture enhancing properties in skin care. Despite its widespread use and popularity, concerns regarding its potential impact on skin health and the environment have led many companies and consumers to avoid dimethicone in skin care. Find out why more people are looking for dimethicone-free products every day, and learn the science of dimethicone here!



If you didn’t already know; the best way to know if a product or ingredient is right for you is to take the Baumann Skin Type quiz for free!




Keep reading to find out how dimethicone works, and why some people avoid it in skin care.



What is Dimethicone?




Dimethicone is a silicon-based polymer, more commonly known as silicones. Its name indicates that it is a silicone based molecule with two methyl groups. (Di=2, methi=methyl, cone=silicon). When you look at it’s structure above, you can see that an oxygen binds two silicon based molecules into one molecule.



This compound has a smooth texture and historically was common in moisturizers and other creamy feeling products. Recently, this ingredient is becoming less popular because of its environmental impact and an influx of great alternatives. If you are interested in moisturizers without dimethicone, you can see our full collection here!




We also have a complete collection of sunscreens and other SPF products without dimethicone, here!



Before we get into why dimethicone is falling out of favor, it is important to understand why it was used in the first place.




Why Dimethicone is used in Skin Care Products



Dimethicone has been used as a texture additive in cosmetic and skin care products for decades. Though it is not in vogue anymore, these are some of the reasons dimethicone was popular in the past:




Moisturizers: By creating a protective layer on the skin, dimethicone help prevent moisture loss, keeping your skin hydrated.



Smooth finish: It creates a silky texture in skincare formulations, leaving a non-greasy finish. Dimethicone doesn’t have the same oiliness as many other creamy ingredients.




Protective Qualities : Dimethicone acts as a barrier against environmental pollutants, helping to shield the skin from external irritants like dirt or smog.



Wrinkle Smoothing : Its ability to fill in fine lines and wrinkles temporarily gives the skin a smoother appearance, a sought-after quality in anti-aging skincare products. It doesn’t actually help with the causes of aging. It’s kind of like using frosting to fill a crack in a wall; It is a very temporary solution.




Understanding these benefits provides insights into why dimethicone has been a preferred ingredient for years. However, the evolving landscape of skincare is marked by a heightened focus on ingredient safety and environmental responsibility. Because of these responsibilities we have to each other and the environment, some people are looking beyond dimethicone.



Why is Dimethicone considered bad?




Dimethicone has gone from a skin care staple to a pariah because of individual skin health concerns and broader environmental implications. Here’s why some consumers and formulators are looking beyond dimethicone:



Potential for Skin Irritation : While relatively rare, there are instances where dimethicone can cause skin irritation or allergic reactions. While only those with extremely sensitive skin have to worry about this issue, it is still notable.




Comedogenicity : Dimethicone’s occlusive nature means it can, in some cases, trap sebum, dirt, and other impurities under the skin. This concern is particularly relevant for individuals with oily or acne-prone skin types. That’s why it’s so important to know your Baumann Skin Type!



Environmental Impact : Dimethicone is not biodegradable. When disposed of, dimethicone does not break down naturally. Some risks to marine life are particularly notable. This ingredient is a major contributor to the larger discussion on the cosmetic industry’s environmental footprint.




Concerns for oral use: Studies by the Cosmetic ingredient review panel demonstrated that when consumed orally, male test subject demonstrated a decrease in muscle mass and the teste size. These results were specific to oral use, however. Using dimethicone on the skin does not seem to cause this same shrinkage.



Dimethicone alternatives




Advances in green chemistry and biotechnology have made alternatives to dimethicone much more accessible. New and old ingredients alike are getting more focus in skin care as dimethicone falls out of favor. Some of the most promising alternatives in my opinion are:



Plant-Based Oils: Ingredients derived from natural sources such as sunflower oil, coconut oil, marula oil, rosehip oil, and more offer a promising path, providing similar benefits in terms of skin feel and hydration, with a significantly lower environmental impact.




Biodegradable Silicones : Innovation in silicone chemistry has led to the development of biodegradable silicones that have almost exactly the same benefits as dimethicone, without the environmental impact.



Dimethicone for hair care




Dimethicone for Hair care



While dimethicone’s presence in skincare has been widely discussed, its application in hair care products deserves a spotlight as well. Known for its conditioning properties and ability to enhance hair texture, dimethicone is a popular ingredient in shampoos, conditioners, and styling products. However, as with its use in skincare, understanding how it works and when it might be best avoided can help consumers make informed choices.


Benefits of Dimethicone in hair care

While the concerns around dimethicone are not to be forgotten about, there are a number of benefits for hair that are commonly attributed to dimethicone:

Smoothness and Shine : Dimethicone coats the hair strands, creating a smooth and shiny appearance. This effect not only makes hair shiny, but also helps in detangling and reducing frizz.

Protection : By forming a protective barrier around the hair shaft, dimethicone can shield hair from environmental aggressors such as pollutants and UV rays. This barrier can help maintain hair health and prevent damage.

Moisture Retention : Similar to its role in skincare, dimethicone helps lock in moisture, which can be particularly beneficial for dry and damaged hair, aiding in hydration and preventing further moisture loss.

Enhanced Conditioning : It is a key ingredient in many conditioners and deep conditioning treatments, where it contributes to the overall softness and manageability of hair, making styling easier and more effective.

Dimethicone’s contribution to hair care demonstrates its versatility as an ingredient in beauty and personal care formulations. While it offers considerable benefits, awareness of its potential drawbacks is essential for hair health. As the beauty industry continues to evolve, the development of innovative, sustainable alternatives will likely provide new opportunities for achieving the desired hair care results without compromising on environmental values or hair health.

Risks of dimethicone in hair care

Despite its advantages, the use of dimethicone in hair care products comes with considerations that users should be aware of:

Buildup Potential : Over time, dimethicone can accumulate on the hair shaft, leading to buildup that can weigh hair down and make it appear limp. This buildup may require specific types of clarifying shampoos to remove, which can strip natural oils from the hair and scalp.

Porosity and Hair Type Sensitivity : The impact of dimethicone varies depending on hair type. While it may benefit those with thick, coarse hair by providing much-needed moisture and frizz control, individuals with fine hair might find it too heavy, leading to a greasy appearance and lack of volume.

Environmental Concerns : Similar to the concerns raised in skincare, the environmental impact of dimethicone, due to its non-biodegradable nature, extends to its use in hair care products. These concerns highlight the need for sustainable practices and alternatives in product formulation.

Some alternatives to dimethicone for hair care are: argan oil, coconut oil, cocoa butter, safflower oil, sesame oil, and these cleansing oils.

DQH Can I use salicylic acid first and then vitamin C? It’s easy to create a skincare routine, but knowing how to use it is another thing entirely. In most cases, if you’re not getting the desired skin results, it could be due to the layering of conflicting ingredients. So, is it possible that salicylic acid and vitamin C are such ingredients? Or are these active ingredients the duo that’s been missing from your skincare routine? If you want answers, stick around because today we are going to explain the benefits of salicylic acid and vitamin C and how they can be used in your daily life. What are the benefits of salicylic acid for skin? Salicylic acid is one of the most commonly used beta hydroxy acids and is favored by many people with oily, acne-prone skin. This acid is derived from willow bark, and unlike its water-soluble relatives (called alpha-hydroxy acids), salicylic acid is oil-soluble, which means it can penetrate deeper into the lower layers of the skin. Once it reaches the lower layers, it can help unclog pores of excess sebum, dirt, bacteria, debris, and impurities. This results in clearer skin tones and greater definition. Not only does salicylic acid benefit the underlying layers, but the outer surface of the skin benefits as well. When applied to the skin, salicylic acid removes the buildup of dead skin cells. This is accomplished by breaking the bonds that hold dead cells to the surface. Over time, this can cause the complexion to look dull and prone to acne, blackheads, and other blemishes. If you’d like to learn more about salicylic acid and how it can improve your skin, check out this dedicated blog post from a beauty insider. What are the benefits of vitamin C for skin? Vitamin C is considered one of the most powerful antioxidants, which means it is very effective at fighting free radicals and preventing them from causing further skin damage. Examples of free radicals include pollution, central heating, UV rays and harsh climate. They attack proteins, fats and cell membranes as soon as they come into contact with the skin, causing signs of premature aging such as fine lines and wrinkles as well as hyperpigmentation, flaky patches of skin and loss of elasticity. Many people usually prefer to use vitamin C in their morning routine as this ingredient gives the complexion a radiant glow. You’ll also find that vitamin C can target areas of hyperpigmentation, plumping the skin and reducing the appearance of fine lines and wrinkles. The thing about vitamin C is that there are a lot of outdated studies going back to the 1950s that describe vitamin C as an unstable skin component. Thanks to improvements in modern technology, this is no longer the case as all products now contain a stable form of vitamin C. Visit The Beauty Insider to learn more about vitamin C. So please check out our blog post. Can I use salicylic acid first and then vitamin C? Yes, you absolutely can. In fact, it’s thought that using salicylic acid before using vitamin C ensures it penetrates faster and works faster. This is an efficient way to utilize two power sources, and the reason has to do with pH. For example, the skin’s natural pH is about 4.7, making it slightly acidic. Salicylic acid and vitamin C are also both acidic, and you’ll find that vitamin C is absorbed quickly into the skin. Therefore, using salicylic acid beforehand can increase the acidity of the skin and allow vitamin C to penetrate into the skin faster. While this is considered an effective way to combine two powerful ingredients, you need to be aware of your skin type and how it reacts to certain active ingredients. Even people with perfect, normal skin can experience skin sensitivity and irritation. Therefore, always consult a doctor or dermatologist before using any new products on your skin. It’s also important to follow skin application rules. In this case, you need to use the product correctly to ensure you get the best results for your skin. If you’re not sure what I mean, the basic rule for skin is to start with the thinnest consistency and work your way up to the thickest consistency. This prevents a barrier from forming on the surface, preventing other active ingredients from penetrating the skin. Can I use salicylic acid at night and vitamin C in the morning? Yes, absolutely, this is considered the most effective way to get returns without any adverse side effects. This is because there is enough time between applications to ensure that the skin’s pH levels return to balance. You’ll also find that Vitamin C is rich in antioxidants and is perfect for use in the morning to ensure your skin is protected and looking its healthiest. Due to the small size of salicylic acid molecules, it is an acid that is able to reach the deepest parts of the skin. While this is effective at keeping skin clear, it also increases the risk of irritation and photosensitivity. Therefore, many people prefer to use powerful BHAs in their evening routine without exposure to UV rays, pollution, or harsh weather. Warning: If you avoid using sunscreen every day, none of these ingredients will do what your skin needs. The combination of chemical peels and powerful ingredients increases the risk of further damage to the skin’s surface. Use SPF 50 every day to keep your skin protected and your lipid barrier healthy, even on cloudy days, keeping your skin in top condition.
