Occlusives in Skincare

Occlusives are a category of moisturizing ingredients commonly found in skincare products. They mainly come in the form of oily or waxy substances such as vegetable oils (e.g., coconut, olive, and castor oil), as well as ingredients like petrolatum, mineral oil, and beeswax. These substances are typically present in various cosmetic products like lotions, occlusive moisturizers, creams, and lip balms. In skincare, the primary role of occlusives is to create a protective barrier on the skin that helps to lock in moisture and prevent dehydration. Unlike humectants that attract moisture to the skin or emollients that soften the skin, occlusives primarily focus on forming a barrier that seals in existing moisture, thus aiding in maintaining the skin’s hydration levels.

How Occlusives Work

Occlusive ingredients have important functions in skin care products:

Prevent water from evaporating off of the skin

Function as an emollient to coat the skin, fill in ridges, and make the skin feel smooth

Push other ingredients that are put under the occlusive into the skin to increase absorption

Prevent absorption or contact of ingredients and allergens that are placed over the occlusive

Protect skin from allergens, irritants and extreme cold

Occlusives are made of oils, fatty acids, or films and patches such as colloidal membranes. Occlusives in moisturizing creams, ointments, hydrating masks and patches prevent water evaporation off of the skin known as transepidermal water loss (TEWL). They prevent TEWL by putting a protective coating on the skin’s surface.

The pressure of the water that wants to evaporate off the skin but cannot because of the occlusive barrier causes a downward pressure on the skin. This downward pressure pushes in any ingredients on the skin’s surface under the occlusive. The pressure of occlusion:

Increases skin penetration and absorption of the skin care product or medication that is placed under the occlusive.

Decreases skin penetration and absorption of anything such as skin care ingredients, allergens and irritants placed over the occlusive.

Occlusives do not have to be moisturizers or cosmetic products. They are often used to deliver drugs. Occlusives can be oils, ointments, plastic wrap or skin patches. For example, nicotine and estrogen patches are on occlusive patches that push the medication into your skin. Saran wrap occludes the skin and increases the penetration of any medication below it. Oils on the skin are occlusive as well.

Occlusion can also happen when one body part pushes on another. For example, if you have large breasts, the skin under the breasts may occlude the skin at the top of the rib cage. This also happens under the arms and in the groin area. This is why these areas can get rashes and skin allergies to certain products- because the allergens get pushed into the skin by occlusion (the pressure of the skin upon other skin).

Occlusive ingredients, patches, masks or plastic wraps have several functions:

Hydrate the skin by preventing evaporation of water off the skin

Prevent evaporation of any medication or skin care product on the skin

Push ingredients or medications into the skin

Protect the skin from friction

Protect the skin from excessively cold temperatures

Speed wound healing by keeping the wound wet and growth factors on the skin’s surface

Some occlusive agents work better than others. The size and material of the occlusive play a large role in determining its effectiveness of the occlusive. A thick plastic for example would occlude more than a light cream moisturizer. An ointment will occlude more than a lotion or a serum. In skincare, larger molecules tend to occlude better than smaller molecules.

However, skincare products with larger occlusive molecules such as ointments tend to be thick and difficult to spread on your skin. For this reason, occlusives are often formulated in skincare products with other ingredients to help make them more spreadable and convenient to use.

Vaseline and Aquaphor are well known occlusives. There is a new skin care trend in to use Vaseline, Aquaphor and other ointments or oils on top of skincare products to “slug” the skin. Slugging the skin means increasing the penetration of skincare ingredients. Click here to learn more about how to use occlusive ingredients to slug the skin. Jello skin is skin that is full of water due to the use of occlusive skin care ingredients.

Occlusives vs Humectants

Occlusives are a type of moisturizing ingredients commonly found in skincare products. These ingredients, such as oils and waxes like coconut oil and beeswax, create a barrier on the skin that locks in moisture and prevents water loss. Unlike humectants, which draw water into the skin, occlusives do not add moisture but instead focus on retaining the skin’s existing hydration levels by forming a protective seal. Humectants, on the other hand, attract water from the environment or deeper layers of the skin to hydrate the skin. Humectants can increase trans-epidermal water loss if not paired with an occlusive. In terms of product types, lotions typically contain humectants, which are effective in moisturizing the skin, especially when the humidity is above 70%.

Mineral oil

Olive oil

Petrolatum

Safflower oil

Tamanu oil

Mineral oil and petrolatum are two of the most effective occlusive ingredients and have been used as effective moisturizers for many decades. Petrolatum and mineral oil are petrochemical byproducts made from crude oil production, so they have a negative impact on the environment.

Environmentally Friendly Occlusives

There are many sustainably grown and harvested sources of occlusive ingredients used in skin care today. If you are concerned about the impact your skin care makes on the globe, consider some of these ingredients.

Argan oil

Avocado oil

Borage seed oil

Coconut oil

Jojoba oil

Marula nut oil

Safflower oil

Sesame seed oil

Shea butter / Shea oil

Sunflower oil

Olive oil*

*Often used as an occlusive on the skin, but it is rich in the fatty acid oleic acid, which can create tiny holes in your skin and therefore damage your skin’s natural barrier. Argan oil is a much better option, as it is high in the fatty acid linoleic acid, which can help to repair the skin barrier and reduce inflammation.

Which Occlusive Ingredients Are Best For Your Skin Type?

The best occlusive ingredients for you depend upon what barriers to skin health you have. To find exactly which occlusive moisturizers, oils, and masks are best for you, shop by your Baumann Skin Type.

In general, occlusive ingredients are best suited to dry skin types that have a hard time retaining water. Occlusives are wonderful at preventing water from evaporating from the skin.

Sensitive skin types often benefit from occlusive ingredients or products because they often, but don’t always, contain anti-inflammatory properties.

Oily skin types might want to avoid some occlusive ingredients with comedogenic properties, like coconut oil, because their skin is prone to acne.

Negative Effects of Occlusives

The potential negative effects of using occlusives in skincare include the risk of developing follicular occlusion syndrome. in this syndrome, occlusives block hair follicles leading to painful bumps, acne, and folliculitis. While occlusives can help prevent contact dermatitis by coating the skin and preventing contact with allergens, they may also increase the severity of contact dermatitis and skin irritation if they are used over irritants or allergens. Some occlusives are comedogenic and clog pores.

Occlusives in Your Skincare Routine

Occlusives should be incorporated into your skincare routine by applying them as the last step in your night skincare routine. They will seal in moisture and any serums or creams applied before them. In fact, they help anything applied before them absorb better. (This is called slugging.) Apply following the direction of hair growth to prevent follicular occlusion syndrome. Avoiding vigorous rubbing. Most occlusive products may feel greasy, such as Vaseline, so it’s advisable to use them an hour or more before bedtime to avoid transferring them onto your pillow.

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.
