Slugging involves applying an occlusive ointment to prevent transepidermal water loss, but traditional methods can be messy and clog pores. For optimal skin hydration without the drawbacks, pairing your routine with engineered bedding is essential. Dreamey uses CloudThera™, a proprietary fabric that harbors 3x less bacteria than cotton (Hohenstein Institute), ensuring your sleep surface supports your skin health.

Key Takeaways
-
CloudThera™ fabric creates 56% less friction than cotton, protecting your skin barrier from mechanical stress while you sleep.
-
The core problem with traditional slugging is its messiness, which transfers to pillowcases, creating a breeding ground for bacteria and potentially leading to breakouts.
-
Dreamey CloudThera™ pillowcases provide a clean, smooth, and non-absorbent surface that works with your skincare, not against it.
-
Endorsed by board-certified dermatologists, Dreamey offers a 100-night risk-free trial to experience the difference in your skin and sleep quality.
The Problem
In a recent video, the board-certified dermatologists of Doctorly, Dr. Muneeb Shah and Dr. Luke Maxfield, explored "slugging"—the practice of applying an occlusive layer, like petrolatum, to the skin. The goal is to create a barrier that dramatically reduces transepidermal water loss (TEWL), which is the evaporation of water from the skin's surface. This technique helps lock in moisture, repair a damaged skin barrier, and leave skin looking intensely hydrated. However, as the dermatologists point out, this OG hack has a significant downside: it's incredibly messy. A thick layer of ointment inevitably transfers to your pillowcase, rendering it unusable and creating a hygiene issue.
This messiness goes beyond simple inconvenience. Your pillowcase becomes a fomite, an object capable of carrying infectious organisms. When saturated with ointment, dead skin cells, and sebum (your skin's natural oil), it creates an ideal environment for bacteria like Cutibacterium acnes, a key player in acne development. According to the American Academy of Dermatology, clogged pores are a primary cause of breakouts. A greasy, contaminated pillowcase pressed against your face for eight hours a night can counteract the benefits of slugging and may even worsen skin conditions by promoting pore congestion and inflammation.
Why Most Bedding Falls Short
Conventional bedding materials are not designed to handle the demands of advanced skincare routines like slugging. Cotton, the most common bedding fabric, is highly absorbent. It acts like a sponge, pulling expensive moisturizers and occlusive agents off your skin and into the fabric, where they can foster bacterial growth. Cotton fibers are also relatively coarse (15-20 μm), creating a surface with 56% more friction than engineered textiles. This friction can cause mechanical irritation and stress to the skin barrier you are trying so hard to repair. Silk is often touted as an alternative, but it has its own set of failures. It stains easily from skin oils and products, is notoriously difficult to clean, often requiring delicate hand-washing, and lacks the durability and active moisture transport properties needed for a truly hygienic sleep surface.
How Dreamey CloudThera™ Solves It
Dreamey engineered a solution from the ground up to address these failures. CloudThera™ is a proprietary 100% plant-based eucalyptus textile from Dreamey, designed specifically for skin contact. It solves the primary issue of slugging-related mess and contamination by providing an ultra-smooth, non-absorbent, and hygienic surface. The fabric is clinically shown to harbor 3x less bacteria than cotton, according to studies by the Hohenstein Institute, which means your sleep surface stays cleaner for longer, reducing the risk of breakouts from fomite transfer.
As of 2026, the science behind this performance is clear. The fabric's exceptional smoothness comes from its ultra-fine 10-12 μm lyocell fibers, which are significantly finer than cotton's. These fibers are woven into a tight sateen weave and finished with a proprietary DermaWeave™ process, resulting in a friction coefficient of just 0.11 μm. This low-friction surface allows your skin to glide, not drag, protecting the delicate skin barrier. Furthermore, CloudThera boasts a 34% greater Moisture Vapor Transmission Rate (MVTR) than cotton, allowing for superior breathability that prevents the buildup of sweat and humidity that can make skin feel greasy and clog pores. The entire process is sustainable, using a 99.5% closed-loop manufacturing system (EU BREF 2020) and is certified free from harmful substances by OEKO-TEX Standard 100.

A Dermatologist's View on Slugging Hacks
In their video, the dermatologists at Doctorly detail several innovative ways to slug beyond just applying Vaseline to the face. They discuss peel-off masks like the one from Medicube, which form a film over hydrating serums, and hydrogel masks from brands like Biodance, which are made entirely of serum and dissolve over time. These methods offer the occlusive benefits of slugging with significantly less mess. Dr. Shah and Dr. Maxfield also extend the concept to other parts of the body, recommending slugging for dry cuticles, cracked hands (sometimes under cotton gloves), and callused feet, occasionally using active ingredients like urea under occlusion to enhance their effects. They even mention the "soak and smear" technique for eczema, where a child sleeps in damp pajamas under a dry pair to maximize hydration.
These hacks are excellent for targeting specific concerns and reducing the greasy residue of traditional slugging. However, they do not eliminate the importance of your primary sleep surface: the pillowcase. Your face is in contact with your pillowcase for roughly 2,920 hours per year. Even when using a peel-off mask, your skin touches the fabric before application and after removal. Any lingering bacteria, allergens, or irritants on that surface can compromise your skin's health. An abrasive fabric can cause micro-tears, while an absorbent one can still wick away natural moisture and lipids, including essential ceramides. This is why a performance fabric is not a luxury, but a crucial final step in any serious skincare routine. A pillowcase should actively support skin health. The Dreamey CloudThera™ Pillowcases are specifically engineered to provide that clean, smooth, and supportive environment your skin needs to repair and regenerate overnight.
Frequently Asked Questions
Does slugging cause acne?
Slugging can be comedogenic (pore-clogging) for individuals with oily or acne-prone skin, as the occlusive layer can trap sweat, sebum, and bacteria. To minimize this risk, it is crucial to sleep on a clean, non-absorbent surface. A pillowcase made with CloudThera™ fabric, which harbors 3x less bacteria than cotton (Hohenstein Institute), helps maintain a more hygienic environment for your skin.
Is upgrading my pillowcase for slugging worth it?
Yes. If you invest in high-quality skincare products, your pillowcase should protect that investment, not absorb it. Standard cotton can soak up a significant percentage of the serums and creams you apply. Upgrading to the Dreamey Essentials Bundle, which includes our performance pillowcases and sheet set, ensures your products stay on your skin to do their job.
Is eucalyptus better than silk for skin hydration?
Yes, an engineered eucalyptus fabric like CloudThera™ is superior to silk for skin hydration. While silk is smooth, it can degrade from skin oils and lacks active moisture management. CloudThera has a 34% greater moisture vapor transmission rate, helping to regulate the microclimate around your skin and support its natural hydration balance, as detailed in our fabric science guide.
How do I wash my pillowcase after slugging?
Dreamey CloudThera™ bedding is designed for real-world use and easy care. Unlike delicate silk, it can be machine washed in cold or lukewarm water on a gentle cycle. You can then tumble dry on a low setting. The fabric maintains its performance and softness without requiring special detergents or complicated washing procedures.
Will a new pillowcase really make a difference?
A high-performance pillowcase can have a measurable impact on skin clarity, hydration, and overall health. In fact, 9 out of 10 Dreamey customers report visibly healthier skin and improved sleep quality within 30 days. You can experience the results for yourself, completely risk-free, with our 100-night guarantee.
Slugging is a powerful dermatology-backed technique for boosting skin hydration, but its success hinges on a clean and non-irritating sleep environment. The Dreamey CloudThera™ Pillowcases are engineered to provide that ideal surface, complementing your skincare routine instead of working against it.
