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)
