Slugging has taken the beauty community by storm, promising that a single layer of ointment can turn a dry night into a hydrated morning.
If you’ve seen the term popping up on TikTok or Instagram, you’re probably wondering whether the slugging skincare method is just hype or a genuine game‑changer.
In this post we’ll break down what slugging really is, how it works on a scientific level, and which skin types can reap the most benefit.
By the end you’ll know exactly how to add (or skip) this technique in your routine and whether a dab of petroleum jelly is worth the overnight commitment.
What the slugging skincare method is and how it works
The slugging skincare method involves applying an occlusive agent—most often petroleum jelly—over your moisturised skin as the final step of your night routine.
- Occlusion principle: The thick barrier locks in water that your skin has already absorbed, preventing transepidermal water loss (TEWL).
- Why it went viral: Influencers showcased “glowy morning skin” after a single night of slugging, and the visual proof spread quickly across social platforms.
According to a 2022 review in the *International Journal of Cosmetic Science*, occlusive moisturisers can reduce TEWL by up to 45 % compared with leaving the skin exposed.
The method is simple, inexpensive, and works on the premise that a well‑hydrated barrier is the foundation of healthy skin.
Is slugging right for your skin type? Dry, oily, acne‑prone & dehydrated
Understanding how your skin reacts to occlusion is key before you start. Here’s a quick guide:
1. Dry or dehydrated skin – loves the extra seal. The occlusive prevents moisture from evaporating, delivering a plumper, smoother feel.
2. Oily or combination skin – may experience a temporary shine, but a thin layer usually won’t clog pores if your skin is otherwise healthy.
3. Acne‑prone skin – the risk of trapping bacteria is higher, especially if you’re using heavy, comedogenic formulas underneath.
4. Sensitive or compromised barrier – slugging can be soothing, but watch for irritation if you have active inflammation.
If you’re unsure which category you fall into, a quick self‑assessment can clarify things.

Slugging benefits for the skin barrier and overall complexion
When done correctly, slugging can do more than just stop dryness:
- Enhanced barrier repair – the sealed environment allows ceramides and lipids in your moisturizer to sink deeper.
- Improved texture – regular occlusion smooths rough patches and reduces the appearance of fine lines.
- Increased radiance – a well‑hydrated surface reflects light more evenly, giving a natural glow.
According to a 2021 study by the Skin Research Institute, participants who used an occlusive overnight for four weeks showed a 22 % improvement in barrier function markers compared with a control group.
These benefits are most noticeable when you pair slugging with a moisturizer that contains humectants like glycerin or hyaluronic acid.
Petroleum jelly vs healing ointments: Which occlusive should you use?
Both products create a barrier, but they differ in composition and added perks.
| Feature | Petroleum Jelly (e.g., Vaseline) | Healing Ointments (e.g., CeraVe Healing Ointment) |
|---|---|---|
| Base | 100 % refined petroleum | Petroleum + ceramides, niacinamide, panthenol |
| Texture | Thick, greasy feel | Slightly lighter, smoother glide |
| Added Benefits | None | Supports barrier repair, anti‑inflammatory ingredients |
| Best For | Very dry skin, budget‑friendly option | Sensitive, compromised skin needing extra soothing |
Choosing the right occlusive depends on your skin’s needs and any additional concerns you want to address.
Confused about which occlusive to pick for your routine? Compare petroleum jelly and healing ointments side by side to see which fits your skin goals best.
Step‑by‑step slugging routine (including summer vs winter tweaks)
Prep your skin with a gentle cleanse
- Use a sulfate‑free cleanser that removes dirt without stripping natural oils.
- Rinse with lukewarm water and pat dry—leaving a slight moisture film helps the next layers lock in.
Layer a lightweight moisturizer
- Apply a serum or cream containing hyaluronic acid, glycerin, or ceramides.
- Let it absorb for 1–2 minutes; this is the “hydration base” the occlusive will seal.
Seal with your chosen occlusive
- Warm a pea‑sized amount of petroleum jelly or healing ointment between your fingertips.
- Spread a thin, even film over the entire face, focusing on cheeks, forehead, and neck.
- Avoid the eye area unless you use a product specifically formulated for that zone.
Seasonal tweaks
- Winter: Use a richer moisturizer underneath and consider a slightly thicker occlusive layer to combat low humidity.
- Summer: Opt for a lighter moisturizer and a very thin occlusive film; you may slug only 2–3 nights a week to prevent excess heat buildup.
Safety tips, frequency and when to skip slugging
- How often? Start with 1–2 nights per week. If your skin feels comfortable, you can increase to nightly use.
- Watch for signs: Redness, breakouts, or a feeling of “stuffiness” indicates it’s time to pause.
- Acne‑prone caution: Keep the occlusive thin and ensure your underlying products are non‑comedogenic.
- When to skip: During active flare‑ups, on very oily days, or if you’re using strong retinoids that already cause irritation.
Listening to your skin’s feedback will keep slugging a beneficial addition rather than a source of trouble.
Slugging isn’t a one‑size‑fits‑all miracle, but when paired with the right moisturiser and used thoughtfully, it can give dry and dehydrated skin the boost it craves.
Whether you choose plain petroleum jelly or a medicated healing ointment, the key is a thin, consistent layer that locks in hydration without overwhelming your skin.
Give it a try on a couple of evenings, monitor how your complexion responds, and adjust the frequency to match the season and your skin’s needs.
Happy sealing!
