What Is Slugging?
The term “slugging” refers to the skincare practice of applying a thick layer of an occlusive agent—typically petroleum jelly—as the final step in a nighttime routine. The name comes from the shiny, slick appearance it gives the skin, resembling the trail left behind by a slug. While the term may sound unappealing, the technique is intended to seal in moisture and support barrier repair overnight. Slugging has recently gained popularity across social media platforms as a so-called miracle step for smoother, plumper, more hydrated skin. But despite its trending status, the method itself is not new. In fact, it draws from decades of medical and dermatological practice, particularly in the field of wound healing. Understanding the true origins, scientific basis, and potential risks or benefits of slugging can help determine whether this technique deserves a place in your skincare routine—or whether it may do more harm than good.
Slugging Is Not New: Clinical Wound Care Origins
Though it’s currently trending in beauty circles, slugging’s underlying principle originates in moist wound healing—a well-documented clinical approach. For decades, dermatologists and wound care specialists have used petrolatum-based ointments to protect skin and enhance healing by maintaining moisture in the wound bed. This practice prevents scabbing and minimizes scarring while supporting the skin's natural recovery processes. In modern skincare, that same occlusive technique has been adapted to improve hydration and restore dry, compromised skin—particularly during colder seasons or after exfoliation.
What Does Slugging Claim to Do?
Proponents of slugging believe it improves skin health and appearance by:
- Enhancing skin hydration overnight
- Reducing dryness and flakiness
- Preventing moisture loss in dry or damaged skin
- Promoting a smoother, more supple complexion
- Acting as a barrier against environmental aggressors
When used correctly and on the right skin types, slugging can help restore comfort and radiance to skin experiencing barrier dysfunction or dehydration.
Is Slugging Right for Your Skin Type?
While slugging can offer benefits, it is not a one-size-fits-all technique. Its effectiveness depends heavily on individual skin type and condition. Below is a professional comparison chart to help determine if slugging is appropriate for your skin:
| Skin Type | Is Slugging Suitable? | Explanation |
|---|---|---|
| Very dry / dehydrated | Yes, often beneficial | Occlusion helps lock in hydration and reduce water loss. |
| Mature skin | Yes, can be helpful | Supports natural barrier function and improves plumpness. |
| Normal skin | Occasionally, with caution | May be used seasonally or after barrier stress. |
| Combination skin | Limited use, apply selectively | Avoid oily areas; may benefit drier zones only. |
| Sensitive / rosacea-prone | Caution and patch test | Occlusion may trap heat or irritants; not ideal for flare-ups. |
| Oily skin | Generally, not recommended | Can feel heavy and increase the risk of congestion or shine. |
| Acne-prone skin | Typically avoid | Occlusives may trap bacteria and exacerbate breakouts. |
Beyond Slugging: Hydration Is Essential for All Skin Types
While slugging may help some skin types retain moisture, hydration itself is essential for every skin type, including oily, acne-prone, and combination skin. Environmental factors such as cold weather, sun exposure, winter sports, and air travel can dehydrate even the oiliest skin, weakening the moisture barrier.
In such cases, lighter alternatives may be more appropriate. Hydrating serums containing hyaluronic acid, glycerin, or panthenol, along with soothing gel masks or barrier-repair creams, can offer lasting hydration without the potential drawbacks of heavy occlusion.
Frequently Asked Questions About Slugging
Is slugging safe for acne-prone skin?
Typically not. Occlusive products may trap oil, debris, and bacteria, leading to clogged pores and breakouts.
Can I use something other than Vaseline for slugging?
Yes. Alternatives like Aquaphor, CeraVe Healing Ointment, or plant-based occlusives can be used, but they should be fragrance-free and non-comedogenic.
How often should I slug my face?
This depends on skin type. Very dry skin may benefit from slugging a few times per week, while combination or normal skin should reserve it for periods of increased dryness. Oily or acne-prone skin types may want to avoid it entirely.
Will slugging clog pores?
It can, especially if applied over unclean skin or on individuals prone to congestion. Thorough cleansing before application is essential.
Do I still need to apply other skincare under slugging?
Yes. Slugging should always follow the application of hydrating serums and moisturizers. The occlusive layer is meant to seal in those products, not replace them.
Is slugging only beneficial in winter?
Not necessarily. Slugging can be useful anytime the skin barrier is compromised—after over-exfoliation, sunburn, or extreme weather exposure. However, it is most used during colder, drier seasons.
Final Thoughts: A Clinical Trend With Cosmetic Appeal
Slugging may be marketed as a trendy beauty ritual, but its foundation lies in legitimate dermatological science. While it can be a helpful technique for restoring moisture and strengthening the skin barrier, it is not universally appropriate.
Understanding your own skin’s needs—along with its limitations—is key. In many cases, hydration can be achieved more effectively through well-formulated serums, masks, and moisturizers designed for your specific skin type, without the need for heavy occlusion.
Regular professional care—including facials, exfoliation, and customized masking—can also reduce the need for more extreme measures like slugging. When the skin is consistently hydrated, well-balanced, and supported with the right ingredients, it becomes naturally more resilient and less prone to dryness or barrier disruption.

When in doubt, consult a licensed esthetician or skincare professional to assess whether slugging—or another more tailored approach—is right for your skin.
