Slugging 101: Who Should (and Shouldn’t) Do It
Share

If you’ve spent any time on skincare social media recently, you’ve likely seen creators coating their faces in thick, shiny layers of ointment before bed. This isn't just a fleeting trend; it’s a technique known as slugging skincare. While it looks a bit intense, it is a practice rooted in dermatological science, specifically aimed at skin barrier repair.
But before you reach for the nearest jar of petrolatum, it is vital to understand the "how" and the "who." In a city like Chicago, where the winter air can be bone-dry and the summer humidity can be suffocating, knowing when to incorporate an overnight occlusive skincare step into your dry skin routine is the key to a healthy glow.

What is Slugging?
At its core, a slugging routine involves applying a thick, occlusive ointment (usually petrolatum skincare) as the final step of your nighttime skincare layering routine.
The goal isn't to moisturize the skin directly with the ointment, but to prevent transepidermal water loss (TEWL). By creating a physical seal, you trap the hydration from your underlying serums and creams, forcing them into the barrier damaged skin to accelerate healing.
The Benefits: Why People are Slugging
- Repair Skin Barrier Fast: If your skin feels tight, stinging, or sensitized, slugging acts like a "security guard," protecting the skin while it repairs itself.
- Hydrate Extremely Dry Skin: It is the ultimate anti-aging hydration routine for those losing moisture due to age or environment.
- Soothe Irritated Skin: It provides immediate relief for treat flaky skin conditions caused by Chicago's harsh windburn.
- Maximize Your Products: It ensures your hydration boosting cream doesn't evaporate into the dry indoor air overnight.
The Critical Question: Who Should Avoid Slugging?
Despite the hype, slugging is not for everyone. If you have the wrong skin type, you could end up with more problems than you started with.
1. Is slugging good for acne prone skin?
No. If you have oily or acne prone skin, slugging can be a disaster. While petrolatum itself is technically non-comedogenic (meaning it doesn't clog pores), it is occlusive. This means it traps everything, including the natural oils, bacteria, and dead skin cells your skin is trying to shed. This environment is the perfect breeding ground for breakouts.
2. Does slugging clog pores?
For people with oily skin, yes, indirectly. By sealing the skin so tightly, you prevent the natural flow of sebum, which can lead to congestion and milia.
3. Who should not do slugging?
- Those with active breakouts or "congested" skin.
- People living in extremely hot, humid environments where the skin needs to breathe.
- Anyone using high-strength actives (like retinols or AHAs) who hasn't consulted an expert first.
The Hero Solution: Trio Rebalancing Moisture Treatment
If you want the benefits of a slugging routine without the heavy, greasy mess of traditional petrolatum, you need a medical grade moisturizer. The Trio Rebalancing Moisture Treatment by SkinBetter Science is the best moisturizer for slugging-style results without the risk of breakouts.
Why Trio is the Professional Choice:
- Triple-Action Rebalancing: Unlike a single-ingredient ointment, Trio focuses on the three pillars of a healthy barrier: hydration, natural moisturizing factors, and lipids.
- Medical Grade Hydrating Cream: It is a dermatologist recommended moisturizer that delivers premium night moisturizer results by mimicking the skin's natural moisture balance.
- Safe for Most Skin Types: Because it rebalances rather than just suffocates, it is a safer anti aging hydration routine for those who find traditional slugging too heavy.
- Fast Repair: It is engineered to repair skin barrier fast, making it the perfect barrier repair cream for the seasonal Chicago transition.
How to Do It Right: The Perfect Slugging Routine

- Cleanse: Remove all city pollutants and makeup.
- Hydrate: Apply a water-based serum or hydration boosting cream.
- Seal: This is where you apply your medical grade hydrating cream or a thin layer of occlusive ointment.
- The "Retinol" Warning: Is slugging with retinol safe? Generally, no for beginners. Slugging increases the potency of whatever is underneath it. If you slug over a strong retinol, you may end up with a chemical burn. Keep your slugging for anti aging nights separate from your retinol nights.
Maximizing Your Results: Slugging for Every Season
The benefits of slugging go far beyond the viral trends you see on social media. To truly transform your complexion, you must integrate this technique into a comprehensive skin care routine that accounts for environmental stressors like the harsh Chicago wind. During the winter months, your skin dries out rapidly, making it essential to create a protective barrier that focuses on preventing water loss overnight.
To get the most out of your slugging skincare practice, follow these expert tips for sealing in moisture:
- The Foundation: Always wash your face with gentle cleansers before starting. Slugging on top of dirty skin will only trap pollutants against the layer of your skin.
- The Layering Strategy: Before applying your occlusive, use high-quality skin care products containing jojoba oil or shea butter. These ingredients mimic the skin’s natural lipids to keep the skin moisturized from within.
- Targeted Care: Don't forget your eye cream. Slugging over your eye treatment can help the active ingredients penetrate deeper to smooth fine lines.
- What to Avoid: Be cautious with mineral oil if you have a history of congestion, as it can be too heavy for some, leaving your skin prone to milia.
- Morning Protection: When you wake up, cleanse thoroughly to reveal an improved skin tone. Always finish with a broad spectrum sunscreen to protect your newly hydrated skin from UV damage.

Conclusion: Is Slugging Your Skin's Solution?

Slugging is a powerful tool for skin barrier repair, especially when you need to soothe irritated skin after a long Chicago winter. However, it requires a strategic approach. If you have dry, flaky, or aging skin, an overnight occlusive skincare step could be your holy grail. If you are oily or acne-prone, it's best to skip the heavy ointments and stick to a medical grade moisturizer that rebalances without clogging.
When done correctly, slugging ensures you stay hydrated and protect your skin against the elements for the long term.
