What Is Slugging and Why Is It Popular in Korean Skincare?
Slugging, a skincare trend sweeping social media, involves applying a thin layer of petroleum jelly as the final step in your nighttime routine. This technique, rooted in "skin cycling" practices and popularized by the Korean beauty industry, creates an occlusive barrier to lock in moisture and enhance product absorption. While petroleum jelly has been a staple in households for over a century due to its gentle, non-toxic formula, its modern use for facial skincare has sparked both excitement and skepticism. Korean beauty influencers often pair slugging with other hydrating ingredients like glycerin or hyaluronic acid to amplify its effects, but its surge in popularity raises questions about suitability for all skin types and potential clogged pores.
How Slugging Supports Skin Barrier Function
Dermatologists agree that a healthy skin barrier is key to glowing skin. Slugging's primary ingredient, petroleum jelly (commonly sold under brands like Vaseline), forms a water-resistant film that prevents moisture loss. This is especially beneficial for those dealing with dehydration or compromised barrier function from over-exfoliating. According to the American Academy of Dermatology, occlusive agents are often recommended for dry skin conditions like eczema or flaky patches, which aligns with slugging's intended purpose. However, unlike medical recommendations for body use, facial application requires caution, as thick occlusives can worsen acne-prone or oily skin if misused.
Who Should Try Slugging — and Who Should Skip It?
While slugging can be transformative for dry or sensitive skin, it's not universally recommended. Those with oily skin or a history of comedones (blackheads and whiteheads) should avoid overloading pores with heavy products. "For non-fragile skin types, lighter alternatives like ceramide- or squalane-based moisturizers might be better," explains board-certified dermatologist Dr. Whitney Bowe in a 2024 interview from "Allure" magazine. Teenage acne sufferers may also find petroleum jelly exacerbates breakouts. Conversely, slugging might soothe irritation caused by retinoids or harsh actives like AHAs and BHAs, which are often highlighted in anti-aging cosmetics discussions.
Step-by-Step: How to Slug Safely at Home
To slug effectively, follow these measures: Cleanse with a gentle, pH-balanced cleanser (a staple in Korean skincare), apply lightweight hydrating products (serums or toners), then pat on a remarkably thin layer of petroleum jelly. Avoid slugging immediately after clay masks or heavy-based acne treatments. Instead, limit it to 2-3 times a week for combination skin types or nightly for dry skin. For men's skincare routines, this adaptation can save time and product costs by replacing complex moisturizing regimens. Always patch-test for allergic reactions to petroleum-based products before applying to the entire face.
Dispelling Slugging Myths: Is It Medically Backed?
Some claims suggest slugging can reverse aging or cure acne scars, but scientific evidence remains anecdotal. While UV protection and face masks (key categories on this website) have established research, occlusive moisturization primarily addresses moisture retention rather than permanent skin rejuvenation. Dr. Bowe adds, "Petroleum jelly isn't a miracle ingredient, but it's excellent for sealing other ingredients like antioxidants or barrier-supporting peptides found in Korean-style essences." Like blue light protection or hand care, slugging should be part of a bigger skincare strategy instead of a standalone solution. Always check for conflicting advice in readers' guides to neck and décolletage skincare, which emphasize lighter formulas for delicate areas.
Alternatives to Traditional Slugging for Sensitive or Oily Skin
If you're wary of petroleum jelly, Korean skincare offers alternatives such as "cotton slugging," which uses silkier occlusive agents like dimethicone or plant-based oils. Some brands blend colloidal oatmeal or niacinamide with lighter textures to avoid clogging pores, tying into acne treatment and skin microbiome health. For teenage skincare, swapping out Vaseline for options like Centella Asiatica-infused balms can mitigate greasiness while maintaining the skin barrier. Likewise, travel-friendly skincare routines benefit from compact occluded balms over bulky jars.
Slugging Meets Oily Scalp Secrets and Hand Care Principle
Interestingly, slugging shares DNA with other forgotten jewels in the skincare realm, like managing an oily scalp with targeted oils and protecting hands against premature aging. Just as petroleum jelly seals moisture on the face, similar occlusives are used in hand creams to combat UV and environmental stressors. Conversely, the "oil-cleansing" method in Korean skincare sometimes clashes with slugging, since mixing or removing oils can backfire if not executed carefully. Scalp treatments, on the other hand, prioritize lightweight oils like jojoba or tea tree oil instead of thick barriers, making them less compatible with slugging ethos for face use.
Pronouncing a Healthy Glow: Final Tips for Effective Nighttime Skincare
Ultimately, slugging aligns with broader trends in beauty sleep science, where overnight recovery is essential for daily skincare routines. To complement this practice, ensure hydration by drinking adequate water (tied to "dehydrated vs. dry skin"), wear protective clothing alongside sunscreen in the morning, and invest in humidity-friendly environments for face masks and slugging to thrive. While the skin microbiome section of our site advocates for balanced routines, slugging fits into the discussion only when paired with practices that promote skin's pH stability and microbiota diversity. Regularly consult updates from "DIY natural cosmetics" articles to test homemade alternatives, though most dermatologists roll their eyes at whipped butters slugging recipes missing occlusive effects.
