The easiest way to get a debate going in the beauty community is by bringing up the topic of preservatives—and parabens are at the forefront of that discussion. Some believe them to be toxic endocrine disruptors, while others say not enough research exists to support those claims. In an attempt to avoid the issue completely, many beauty companies are reformulating without the use of parabens in favor of alternative ingredients. And in the wake of those changes, consumers are left to wonder about the safety of the other ingredients being used instead, like benzyl alcohol, and whether or not preservatives are all that important in the first place. So what's the deal?
Dermatologist Jessica Krant, MD, says that preservatives do have an important role and deserve a place in your skincare products. "Preservatives are vital for any product that we want to last more than a few days in the bottle—and not have to keep in the refrigerator," she explains. "They help to keep germs out and to keep the products from turning rancid or discolored."
But because some might still be on the fence about using preservatives, we turned to Krant as well as two other experts for their opinions on one of the more common paraben alternatives.
Meet the Expert
- Jessica Krant, MD, is a board-certified dermatologist at Laser & Skin Surgery Center of New York.
- Michelle Wong has a chemistry PhD and is a content creator at Lab Muffin Beauty Science.
- Geeta Yadav, MD, is a board-certified dermatologist and founder of Skin Science Dermatology.
Here's what these experts have to say about the specific ingredient benzyl alcohol and whether or not you're safe to use it in your skincare.
Benzyl Alcohol
Type of ingredient: Preservative, antioxidant, and solvent
Main benefits: Preserves, stabilizes, and dissolves ingredients
Who should use it: In general, benzyl alcohol is safe to use by anyone who does not have a true contact allergy to it. Krant adds that those who prefer un-preserved products would want to avoid products containing standard preservatives like benzyl alcohol, though it may risk contamination.
How often can you use it: Benzyl alcohol is safe to use daily if you're not sensitive to it and if it's used at a low concentration.
Works well with: Benzyl alcohol works well with most, if not all, other ingredients.
Don't use with: Benzyl alcohol works well with most, if not all, other ingredients.
What Is Benzyl Alcohol?
Although it's most widely known as benzyl alcohol, the aromatic alcohol also goes by a few other names, such as benzene methanol or phenylcarbinol. It's derived from fruit (usually cranberries and apricots, says Yadav), comes in the form of a colorless liquid, and has a slightly sweet scent. As a multifunctional ingredient, you can spot benzyl alcohol on the ingredient label of many different skincare, cosmetic, and personal products, such as moisturizers, lip balms, face washes, and even makeup.
According to Wong, it's primarily used in product formulation as a preservative to stop microorganisms from overgrowing in products, which could later lead to an infection. "It's mostly used because of the scaremongering about parabens," Wong says. "Since a lot of consumers are worried about parabens, alternative preservatives have to be used for marketing reasons. It's found naturally, so companies can use it in products and still market them as 'natural.'"
Benefits of Benzyl Alcohol for Skin
Besides possibly having antioxidant effects in certain formulas, benzyl alcohol doesn't have any specific benefits for your skin itself, but rather helps to optimize skincare formulas so that they can better perform for your skin.
- Preserves the product: According to Yadav, benzyl alcohol acts as a preservative in skincare and cosmetic products due to its antibacterial and anti-fungal properties. "Any cosmetic or personal care product that is made with no preservatives (for example, preservative-free eye drops) generally comes in individual single-use containers to prevent contamination by contact or air," Krant says. Benzyl alcohol allows products to be bottled in larger packages designed for more than one use.
- Stabilizes the formula: Krant adds that the ingredient also acts as a stabilizing agent against the oxidative breakdown of the product, which means it allows your products to work more effectively for a longer period.
- Has antioxidant activity: Krant says benzyl alcohol also has antioxidant properties, and antioxidants protect against free-radical damage.
- Dissolves ingredients: Benzyl alcohol acts as a solvent and helps to dissolve other ingredients in a product's formula.
- Decreases viscosity: Benzyl alcohol also decreases viscosity, which allows products to flow more easily.
- Imparts a nice scent: As an aromatic alcohol, benzyl alcohol is naturally fragrant and gives off a slightly sweet scent. Yadav says it's also naturally found in some essential oils, including ylang-ylang and jasmine, and has a delicate floral scent.
Side Effects of Benzyl Alcohol
"Benzyl alcohol is considered to be a safe ingredient in skincare and cosmetics when used on intact skin," Krant says. With that said, you might have seen benzyl alcohol on a list of "bad" alcohols once or twice before.
- Can cause itching for some people: "As is the case for most preservatives, benzyl alcohol can, unfortunately, be an irritant and cause itching for some people," says Krant.
- Toxicity is possible with overuse: "Toxicity is a possibility with excessive ingestion, which is not considered a risk with normal usage," says Wong, adding that it's safe when used at a low concentration—and it usually is in well-formulated products.
However, Yadav points out that only in rare cases is someone actually allergic to benzyl alcohol. If you experience an adverse reaction (such as swelling, or redness) to products containing benzyl alcohol and suspect you could have an allergy to it, Krant says this can be identified through formal skin allergy patch testing with your dermatologist or allergist.
As for more serious risks of using the preservative in your products, those concerns aren't as valid. "The potential for allergenicity is low, and low risk of toxicity," Krant says.
How to Use It
As long as you don't have an allergy to benzyl alcohol, Krant and Wong say it's totally fine to use in your regular skincare routine. Because the ingredient is included in such a wide range of cosmetics, the time of day you would apply it, as well as the step in your routine, depends on each specific product.
The Best Products With Benzyl Alcohol
It seems as though "wrinkle creams" are synonymous with "expensive creams," but it doesn't have to be that way. Enter: This iconic face cream from Olay. Packed with the same ingredients you'd find in a prestige cream, like vitamin B3, amino-peptides, hyaluronic acid, and antioxidants, this formula promises to noticeably soften, plump, and firm (it even made Byrdie's list of best wrinkle creams). And with an open tub packaging like this, you'll be thankful for the benzyl alcohol in the formula that keeps your fingers or air from contaminating your little pot of gold.
Of all the pH-adjusting lip products, this Byrdie favorite is the crème de la crème. Somewhere between a lip balm and a lipstick, this lip glow imparts the perfect natural tint with all the comfort of a lip treatment. As we mentioned before, preservatives play a big part in killing parasites and microbes. Since you won't want to stop applying this product directly to your lips all day long, the importance of benzyl alcohol in keeping it free of contamination is beyond clear.
If you're searching for a face wash that cleanses and exfoliates without stripping or damaging your skin's protective barrier, look no further. One of Byrdie's top glycolic acid cleaners, this foaming face wash removes makeup, dead skin, dirt, and impurities without compromising any of the good stuff.
Dermatologists and beauty editors alike are fans of this drugstore brand for the impressive quality at an even more impressive price. This moisturizer, in particular, has us singing its praises for its lightweight, non-greasy feel, despite the fact that it also contains sunscreen. Props to benzyl alcohol for its easy product flow and for keeping it free of contamination.
The Byrdie editors fell in love with this tinted moisturizer for its light creamy texture, self-adjusting tint, and sun protection and if you're in the medium skin-tone range, you'll soon be obsessed with it, too. Thanks to the preservative and stabilizing properties of the benzyl alcohol included in the formula, you'll get to savor every last bit of the larger-than-life jar (a whopping 2 fluid ounces). Now if only it came in more than one shade…
Whether you're an overexuberant hand-washer or just gearing up for a long winter ahead, this hand cream is one you'll want to (forgive us) keep on hand. Byrdie loves this product for its main ingredient, lanolin, which is meant to soften and hydrate even the driest hands, cracked knuckles, and compromised cuticles—but don't sleep on its other important ingredients, like benzyl alcohol, shea butter, and cetearyl alcohol.
Yep, even makeup foundations contain benzyl alcohol, and you'll be grateful for those antimicrobial properties as you smear it all over your face. This foundation, in particular, is a Byrdie-approved must-try for its incredible coverage, impressive shade range, and airbrush finish. Did we mention it has 430k loves on Sephora?
