Why Skincare Experts Are Rethinking Dimethicone-Based Products

The Science of Dimethicone in Skincare

Dimethicone is a silicone-based ingredient that was once valued for its texture-enhancing properties in skincare.

Despite its versatility and popularity, many companies and consumers have avoided using dimethicone in skincare due to concerns about its potential impact on skin health and the environment.

Read on to learn how dimethicone works and why some people avoid it in their skincare.

What is Dimethicone?

Dimethicone is a silicon-based polymer, commonly known as silicone. Its name indicates that it is a silicon-based molecule with two methyl groups (Di=2, Methi=Methyl, Cone=Silicon).

The structure above shows that oxygen binds two silicon-based molecules into one molecule.

This compound has a smooth texture and was once commonly found in moisturizers and other cream products.

Recently, this ingredient has fallen out of favor due to its impact on the environment and the increasing availability of quality alternatives.

Before we get into the reasons for the increasing use of dimethicone, it’s important to first understand why it was used in the first place.

Why Dimethicone Is Used in Skincare

For decades, dimethicone has been used as a texturizing additive in cosmetics and skincare products. Although dimethicone is no longer popular, here are some of the reasons why it was once so popular:

Humectant: By forming a protective layer on the skin, dimethicone prevents water loss and keeps the skin hydrated.

Smoothing effect: It gives skincare a silky texture and is non-greasy. Dimethicone is not greasy like many other creamy ingredients.

Protective properties: Dimethicone acts as a barrier against environmental pollutants, protecting the skin from external irritants like dirt or smoke.

Wrinkle-smoothing: The ability to fill fine lines and wrinkles can make skin look temporarily smoother—a highly sought-after property in anti-aging skin care products.

It actually does little to prevent skin aging. It’s like filling a crack in a wall with frosting; it’s a very temporary solution.

Knowing these benefits explains why dimethicone has been a go-to ingredient for years.

However, the evolving skin care industry is characterized by a greater focus on ingredient safety and environmental responsibility.

Some are interested in more than just dimethicone because of their responsibility to each other and the environment.

Why is dimethicone considered harmful?

Dimethicone has gone from being a skin care product to an outlier due to personal skin issues and general environmental influences.

Here are some reasons consumers and formulators use more than dimethicone:

Potential skin irritation: Although relatively rare, dimethicone can cause skin irritation or allergic reactions. Although this problem only occurs on extremely sensitive skin, it still exists.

Comedogenicity: Due to dimethicone’s occlusive effect, it can trap sebum, dirt, and other impurities under the skin in some cases.

This issue is particularly important for people with oily skin or those prone to acne. That’s why it’s so important to know your Bowman skin type!

Environmental impact: Dimethicone is not biodegradable. Dimethicone does not naturally break down when handled. Some risks to marine life are particularly noteworthy.

This ingredient has made a significant contribution to the discussion of the ecological footprint of the cosmetics industry.

Oral issues: Studies by the Cosmetic Ingredient Review Panel showed a decrease in muscle mass and testicular size after oral administration in male subjects.

However, these results only apply to oral administration. Applying dimethicone to the skin does not seem to cause this shrinkage.

Alternatives to Dimethicone

Advances in green chemistry and biotechnology have made alternatives to dimethicone more accessible.

As dimethicone gradually loses popularity, new and old ingredients are gaining traction in the skincare space. In my opinion, the most promising alternatives include:

Plant oils: Ingredients from natural sources, such as sunflower seed oil, coconut oil, marula oil, rosehip oil, etc., are a promising alternative.

They offer similar benefits in terms of skin feel and moisture supply, but are more environmentally friendly.

Biodegradable Silicones: Innovations in silicone chemistry have led to the development of biodegradable silicones that offer nearly identical benefits to dimethicone, but without the environmental impact.

Dimethicone in Hair Care

While the use of dimethicone in skin care products has been widely discussed, its use in hair care products deserves special attention.

Known for their conditioning properties and ability to improve hair quality, dimethicone is a common ingredient in shampoos, conditioners, and styling products.

However, just like their use in skin care, understanding how they work and why they should be avoided can help consumers make informed decisions.

Benefits of Dimethicone in Hair Care

Despite concerns about dimethicone, dimethicone is generally considered to have many benefits for hair:

Smoothness and Shine: Dimethicone coats hair strands, making them appear smooth and shiny. This effect not only makes hair shiny, but it also helps detangle and reduce frizz.

Protects: By forming a protective barrier around the hair shaft, dimethicone shields hair from environmental influences such as pollutants and UV rays.

This barrier can help keep hair healthy and prevent damage.

Moisturizes: Similar to skincare, dimethicone helps retain moisture, which is especially beneficial for dry and damaged hair because it supports hydration and prevents further moisture loss.

Improves Care: It is a key ingredient in many conditioners and deep conditioning products, helping to make hair overall soft and manageable, making styling easier and more effective.

Dimethicone’s contribution to hair care demonstrates its versatility as an ingredient in beauty and personal care formulations.

Despite its significant benefits, it is important to be aware of its potential drawbacks for the sake of hair health. The beauty industry is constantly evolving.

The development of innovative, sustainable alternatives may open up new opportunities to achieve desired hair care results without compromising environmental sustainability or hair health.

Risks of Dimethicone in Hair Products

Despite its many benefits, using dimethicone in hair products also comes with some aspects that users should consider:

Potential for accumulation: Over time, dimethicone can build up on the hair shaft, causing hair to weigh down and appear limp.

To remove these deposits, a special cleansing shampoo may be necessary, which strips the hair and scalp of natural oils.

Porosity and hair type sensitivity: The effectiveness of dimethicone varies by hair type.

While it can provide needed moisture and tame frizz for thick, coarse hair, it can be too heavy for fine hair, causing it to be greasy and lack volume.

Environmental concerns: Similar to skin care products, the environmental impact of dimethicone can affect its use in hair products due to its non-biodegradable nature.

These concerns highlight the need for sustainable processes and alternatives in product formulations.

Alternatives to dimethicone in hair care are: argan oil, coconut oil, cocoa butter, safflower oil, sesame oil, and these cleansing oils.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
