From slugging to ice rollers, TikTok has become the go-to place for viral skincare hacks. But with so many trends popping up, it’s hard to tell which ones are worth trying—and which ones could actually harm your skin.

Here are a few trendy skincare hacks that dermatologists say can be safe and effective (when done correctly).


1. Slugging (Petroleum Jelly Overnight)

The trend: Applying a thick layer of petroleum jelly (like Vaseline) as the last step in your nighttime routine to “seal” moisture in.

Derm-approved when used correctly

  • Helps repair the skin barrier
  • Great for dry, sensitive, or eczema-prone skin
  • Not ideal for oily or acne-prone skin (may clog pores)

2. Ice Rolling / Skin Icing

The trend: Using ice cubes or a cooling roller to reduce puffiness and brighten skin.

Safe with moderation

  • Can temporarily reduce swelling and redness
  • Helps soothe inflamed pimples
    Avoid direct ice on bare skin—always wrap in a soft cloth to prevent irritation.

3. Honey Masks

The trend: Applying raw honey (often manuka honey) as a face mask for hydration and acne.

Backed by science

  • Honey has antibacterial and soothing properties
  • Can calm redness and speed up healing
  • Works well for sensitive or acne-prone skin

4. Skin Cycling

The trend: Rotating products (like retinol and exfoliants) across different nights to reduce irritation.

Highly recommended

  • Example routine:
    • Night 1: Exfoliation
    • Night 2: Retinol
    • Nights 3 & 4: Moisturize & repair
  • Prevents over-exfoliation and supports skin recovery

5. “Glass Skin” Routine

The trend: Layering hydrating products for a smooth, dewy, “glass-like” finish.

Effective with the right products

  • Focuses on hydration and barrier repair
  • Can be achieved with hyaluronic acid, niacinamide, and lightweight moisturizers
  • Consistency matters more than buying 10 new products

Trends to Avoid

Not every TikTok skincare hack is safe. Skip:

  • DIY lemon juice masks (too acidic, can cause burns)
  • Toothpaste on pimples (irritating and drying)
  • Sunscreen contouring (dangerous UV exposure)
