If you’ve ever heard of occlusives but are curious about their benefits, you’re not alone. In a world of buzzy skincare ingredients, deciphering the ingredient list on your favorite moisturizer can feel like a challenge. So here’s what you need to know: There are three main categories of moisturizing ingredients: emollients, humectants, and—you guessed it—occlusives. The latter of the three is often considered to be especially beneficial for dry or dehydrated skin. In this guide, we’re exploring the benefits of occlusives and sharing helpful tips for incorporating these ingredients into your skincare routine for dry skin. Keep reading for the lowdown on how occlusive moisturizers work, which skincare products fall into this category, and how to use them in your routine for hydrated, softer-feeling skin. What Are Occlusives in Skincare? You may already have some experience with occlusives and not realize it. One of the most well-known ingredients in this category is petroleum jelly (petrolatum) which can be found in countless ointments, creams, lotions, and lip balms. Occlusive moisturizers tend to have an oily or waxy texture and are generally considered to be the thickest moisturizer option. While petrolatum is often considered the best occlusive moisturizer, many other ingredients also have occlusive effects—including beeswax, dimethicone, mineral oil, lanolin, and squalene (more on these ahead). Occlusive moisturizers have gained popularity in recent years due to the rise of skincare trends for dry skin like slugging—a technique that involves applying an occlusive as the final step in your nighttime skincare routine to seal in moisture. With that said, occlusives have been a mainstay in moisturizing products for decades, with petrolatum first being patented for cosmetic use in 1872. How Do Occlusive Moisturizers Benefit Dry Skin? Unlike humectant moisturizers, occlusives don’t hydrate your skin. Instead, they sit on your skin’s surface, creating a physical barrier that helps prevent transepidermal water loss (TEWL). In plain English: They trap moisture in your skin and keep it from evaporating off your skin’s surface (the definition of occlusive is literally “something that obstructs”). The result? Occlusives can help your skin retain moisture for longer, making them especially helpful for dry skin. One clinical study found that participants who used occlusive moisturizers saw a sustained improvement in skin hydration after just five days. According to the American Academy of Dermatology (AAD), occlusive ointments may be less irritating and more effective options for those with dry skin. Because they provide your skin with a protective barrier, occlusives may also help protect dry skin from irritants and allergens in the environment. This is why you’ll find occlusives used in many skin protectants, such as CeraVe Healing Ointment. The protective layer created by occlusive ingredients can also be especially beneficial during the harsh winter months when your skin is exposed to freezing temperatures and dry air. Popular Occlusive Ingredients for Dry Skin While some occlusive ingredients can be found in their purest form (such as petroleum jelly), others are included in skincare formulations alongside popular humectants and emollients, like hyaluronic acid and glycerin, for added benefits. Here are some examples of common occlusive ingredients used in moisturizers for dry skin: Oils and oil-based waxes: These types of occlusives include mineral oil, paraffin, and petrolatum (petroleum jelly). Research shows that petrolatum is the most effective occlusive moisturizer, with the ability to reduce transepidermal water loss by more than 98%. Silicones and silicone derivatives: Some silicones used in skincare formulations, like dimethicone, are also well-known for their occlusive properties. You’ll find dimethicone in many rich creams, including L’Oréal Paris Revitalift Triple Power Anti-Aging Overnight Mask. Wax esters: These include ingredients like lanolin and beeswax, the latter of which is commonly found in lip balms, like Kiehl’s Butter Mask For Lips. Vegetable waxes: Certain vegetable waxes, including carnauba wax, have semi-occlusive properties that can help seal in moisture for softer, smoother skin. Vegetable oils: Some vegetable oils, such as shea butter, squalane, and coconut oil, may also offer semi-occlusive benefits. Look for shea butter in rich, nourishing body lotions like Youth to the People Superberry Firm and Glow Body Butter. How To Incorporate Occlusives Into Your Routine If your skin feels perpetually parched or you’re experiencing seasonal dryness, it may be time to include an occlusive product in your routine. It’s likely that your moisturizer may already contain one or more occlusives, so how can you be sure that you’re getting the most out of these ingredients? Here are a few tips to help you get started. Occlusive moisturizers should generally be applied onto slightly damp skin as the last step in your skincare routine. For dry, flaky patches of skin on your body, a pure occlusive (like petroleum jelly) or ointment may be preferable for targeted relief. Remember to apply it to damp skin to help trap in much-needed moisture. Apply an occlusive ointment onto exposed areas of skin before heading outdoors in the winter—this can help protect your skin against the drying effects of harsh winter weather. Try applying a petrolatum-based ointment on dry eyelids, cuticles, heels, and lips to help combat dryness in these areas. Pure petroleum jelly may feel too heavy or greasy for your facial skincare needs. For this reason, we suggest opting for facial moisturizers that include a combination of occlusives, humectants, and emollients. If your dry skin doesn’t improve with consistent use of occlusive ointments and moisturizers, it’s best to speak with a board-certified dermatologist. They can assess your dry skin and offer the right solution for your needs. 8 Moisturizers To Try for Dry Skin Check out some of our favorite moisturizers for dry skin that feature occlusive ingredients, below.
