Overnight Occlusive Trend

Slugging - coating face in petroleum jelly (Vaseline) before bed to lock in moisture - became TikTok’s viral skincare trend (2021-2022) via K-beauty influence, dermatologist endorsements, and satisfying transformation videos.

The method: After skincare routine, apply thick layer of Vaseline or petroleum-based occlusive; sleep with it; wake with glowy skin

Korean origins: K-beauty practice for decades; TikTok Western discovery rebranded it “slugging” (shiny, slug-like appearance)

Why it works: Petroleum jelly creates barrier preventing transepidermal water loss; locks in serums, moisturizers underneath

TikTok virality: Before/after videos showing dewy morning skin; 600M+ #slugging views (2022)

Dermatologist validation: Pros confirmed benefits for dry skin; cautioned against acne-prone skin (comedogenic risk)

Product boom: CeraVe Healing Ointment, Aquaphor, La Roche-Posay Cicaplast became slugging staples

Variations: Slug masks (sheet masks soaked in slugging products), body slugging, targeted slugging (lips, hands)

Criticism: Gross factor, stained pillowcases, not suitable for oily/acne skin, overhyped simple technique

Lasting impact: Normalized occlusive final step; introduced Gen Z to barrier repair

Slugging represents TikTok skincare’s pattern - rebranding old practices through aestheticized content and dermatologist validation.
