In the ever-evolving world of skincare trends, TikTok has become the birthplace of viral beauty routines that resonate with both novices and enthusiasts alike. One of the latest—and arguably most effective—trends to gain traction is called “Skin Flooding.” Unlike fads that promise instant miracles, skin flooding is rooted in solid dermatological science and delivers visible, healthy hydration by following a strategic sequence of skincare layering.
From beauty influencers to licensed estheticians, skin flooding is receiving praise for its gentle, effective, and skin barrier-supportive approach. But what exactly is skin flooding? How do you do it? And why is it quickly becoming a go-to hydration ritual in every skincare routine?
Let’s dive in.
What Is Skin Flooding?
Skin flooding refers to a layered hydration technique that involves applying multiple lightweight moisturizing products, in the right order, onto damp skin. The goal? To flood the skin with moisture, reinforce the skin barrier, and prevent transepidermal water loss (TEWL)—especially for dry, dehydrated, or sensitive skin types.
Instead of relying on one heavy cream, the idea is to build hydration gradually, using humectants, hydrating serums, and occlusives to seal it all in.
Why It’s Trending on TikTok
With the hashtag #skinflooding garnering millions of views, the trend taps into the desire for dewy, plump, and healthy skin—a look made popular by the Korean beauty philosophy of glass skin. But beyond aesthetics, skin flooding is being celebrated for its science-backed benefits and accessibility.
Unlike harsh exfoliation trends or expensive treatments, skin flooding can be done with products you already have, and it works for nearly every skin type, including acne-prone and aging skin.
The Science Behind Skin Flooding
Skin flooding is more than a social media fad—it’s a smart skincare strategy. Here’s the science that supports it:
- Damp skin is more permeable: Applying products on damp skin allows active ingredients and hydration to penetrate better.
- Layering humectants like hyaluronic acid helps draw moisture into the skin from the environment or deeper layers.
- Occlusives like squalane or ceramides lock that moisture in, creating a barrier that prevents water loss and maintains elasticity.
This combination mimics the skin’s natural hydration system, boosting resilience and glow from within.
Step-by-Step: How to Do Skin Flooding Properly
The effectiveness of skin flooding lies in the order and type of products used. Here’s a typical step-by-step routine:
Step 1: Start With Clean, Damp Skin
Begin with a gentle, non-stripping cleanser. After rinsing, do not towel dry completely. The skin should still be slightly damp to enhance product absorption.
Step 2: Apply a Hydrating Mist or Toner
Use a hydrating mist, essence, or toner that contains ingredients like glycerin or aloe vera. This sets the stage for deeper hydration.
Step 3: Layer a Humectant-Based Serum
This is the heart of skin flooding. Apply a serum rich in hyaluronic acid, polyglutamic acid, or panthenol. These ingredients draw water into the skin and plump it from the inside out.
Step 4: Follow With a Barrier-Strengthening Serum
Optionally, follow with a niacinamide or peptide serum to support the skin barrier, especially if you have sensitive or redness-prone skin.
Step 5: Lock It In With a Moisturizer or Facial Oil
Finish with a ceramide-rich cream, squalane oil, or any non-comedogenic moisturizer. This step prevents moisture from evaporating and keeps your skin hydrated longer.
Step 6: Sunscreen (Morning Only)
If it’s your morning routine, don’t forget to apply a broad-spectrum sunscreen as your final step.
Who Can Benefit From Skin Flooding?
Skin flooding is especially beneficial for those with:
- Dry or dehydrated skin
- Irritated or sensitized skin
- Post-acne marks or flaking
- A compromised skin barrier from over-exfoliation
- Mature skin with visible fine lines
Even oily or combination skin types can benefit by adjusting the richness of products used. For example, use gel-based serums and oil-free moisturizers.
Tips to Maximize Results
- Avoid harsh actives right after flooding (like retinol or strong acids).
- Use fragrance-free products if you have sensitive skin.
- Consider adding an occlusive balm at night if you have severe dryness (also known as slugging).
- Be consistent—skin flooding works best as a routine, not a one-time fix.
Common Mistakes to Avoid
- Using too many thick products: This can clog pores and reduce absorption.
- Applying products to dry skin: Always start with damp skin to trap more moisture.
- Skipping the sealing step: Without a final moisturizer or oil, the hydration won’t last.
- Layering incompatible ingredients: Avoid combining exfoliants or retinoids directly after skin flooding unless recommended by a dermatologist.
