The Ultimate Guide to Slugging: Unlocking Dewy, Hydrated Skin
Learn everything about slugging—from its origins to its step-by-step routine—so you can decide if this viral skincare technique is right for you.
What Is Slugging?
Slugging is a popular skincare technique that entails applying an occlusive product—most commonly petrolatum or petroleum jelly—as the last step of your nighttime routine to lock in moisture and help repair the skin barrier. The name ‘slugging’ refers to the shiny, slick finish these products leave on the skin, reminiscent of a slug’s trail.
The method found viral fame due to Korean beauty routines, but it has roots in Black and Brown households, where petroleum jelly has long been used to protect and hydrate skin.
How Does Slugging Work?
Slugging utilizes occlusives—ingredients that form a physical seal over the skin. This seal traps in moisture, prevents transepidermal water loss (TEWL), and allows the skin to heal more efficiently overnight.
- Occlusive effect: Slugging products don’t hydrate your skin directly. Instead, they seal in existing moisture, including anything absorbed from your serums and creams.
- Improved ingredient absorption: By locking down actives like hyaluronic acid and niacinamide, slugging can enhance their effects.
- Skin barrier repair: Ideal for dry, sensitive, or irritated skin, slugging supports the healing of a compromised skin barrier.
- Fresh, dewy complexion: Many users report waking up to plumper, softer, and smoother skin.
Who Should Try Slugging?
Slugging can benefit many skin types, but it’s particularly effective for those with dry or sensitive skin.
- Dry skin: Nightly slugging boosts radiance and texture.
- Combination or oily skin: Best practiced 2-3 times weekly, as too much occlusion may lead to breakouts.
- Compromised skin barrier: Ideal for recovery after harsh weather or over-exfoliation.
- Not for: Acne-prone skin types should be cautious, as occlusives may trap excess oil and exacerbate breakouts.
Step-by-Step Slugging Routine
Implementing slugging is as simple as layering, but proper order and product choice maximize results:
- 1. Cleanse thoroughly:
Begin with a gentle cleanser to remove dirt, oil, and makeup. If exfoliating, do so 1-2 times per week, but avoid immediately before slugging if your skin is sensitive.
- 2. Apply thinnest skincare products (serums, toners):
Let serums, especially those containing hydrating actives (e.g., hyaluronic acid, glycerin), penetrate fully.
- 3. Layer on moisturizer:
Choose a lightweight or hydrating moisturizer appropriate for your skin type.
- 4. Apply occlusive product:
Spread a thin, even layer of petroleum jelly or an ointment like CeraVe Healing Ointment over your entire face, avoiding eye and lip areas if sensitive.
- Warm the product between your hands for easier spread.
- Wait 15-30 minutes after applying other products to maximize absorption.
Pro tip: Place a clean towel over your pillow, and tie hair back to avoid transferring product onto bedding.

Potential Risks and Common Concerns
- Acne and breakouts: Slugging may cause breakouts in those with oily or acne-prone skin. Always patch-test and consult a dermatologist for personalized advice.
- Transfer to bedding: Shiny, sticky skin can leave residue on your pillow and sheets—use protective covers if necessary.
- Clogged pores: Using comedogenic occlusives increases risk—stick with trusted brands and non-comedogenic formulas.
- Not for daytime use: Occlusives are too thick for makeup layering; slugging is a nighttime ritual.

Slugging’s Origins: A Rich History
While recently popularized by Korean beauty trends and social media, slugging is far from new. Black and Brown communities have used petroleum-based occlusives for generations to protect skin from harsh weather and promote healing. Today, slugging bridges cultural wisdom with modern skincare science.
The Science Behind Slugging
Occlusives are a class of skincare ingredients that create a barrier over the skin, reducing moisture evaporation. Petrolatum—the most popular occlusive in slugging—has been shown to reduce water loss by up to 99%.
- Occlusives do not add hydration; they prevent water from escaping.
- This “seal” enables other ingredients (e.g., peptides, antioxidants) to work more efficiently overnight.
- Skin regenerates almost exclusively at night, making slugging an optimal technique for enhanced results.
Benefits of Slugging
- Enhanced hydration: Wake up to skin that’s plump and dewy.
- Smoother, softer texture: Visibly restores rough or flaky patches.
- Repair of compromised skin barrier: Ideal after irritation or harsh environmental exposure.
- Boosts the efficacy of active ingredients: Retains serums and moisturizers for maximized impact.
- Budge-friendly: Petroleum jelly is affordable and widely available.
Expert Tips for Safe and Effective Slugging
- Consult your dermatologist before starting slugging, especially if you have acne-prone or sensitive skin.
- Limit frequency for oily or combination skin.
- Choose non-comedogenic occlusives to avoid blocked pores.
- Use a thin layer; more is not always better.
- Consider slugging only during winter or in harsh climates.
Frequently Asked Questions (FAQs)
Q: Can slugging cause acne breakouts?
A: Yes, slugging may increase the risk of acne or breakouts, especially for those with oily or acne-prone skin. Use non-comedogenic products and patch-test first.
Q: How often should I use slugging in my routine?
A: Daily for very dry skin, and 2–3 times weekly for oily or combination skin. Adjust based on individual needs.
Q: Which product is best for slugging?
A: Petroleum jelly (e.g., Vaseline) or a non-comedogenic ointment (e.g., CeraVe Healing Ointment) are most commonly recommended.
Q: Is slugging safe for sensitive skin?
A: Generally yes, especially if the barrier is compromised or very dry. Always start slowly and consult with a professional.
Q: Should slugging be done in the morning or at night?
A: Slugging is best as the last step in your nighttime routine; occlusives are too heavy for daytime use.
Conclusion: Is Slugging Right For You?
Slugging is a time-tested technique to boost hydration, repair the skin barrier, and maximize ingredient absorption overnight. If you suffer from dry, sensitive, or compromised skin, slugging may be a game-changer in your routine. However, if you are acne-prone, proceed with caution and consult your dermatologist before introducing occlusives.
Like all beauty trends, customize slugging to your skin’s unique needs and observe how your complexion responds for the best possible result.
