If you have dry or dehydrated skin, you’ve probably heard about slugging and skin flooding—two trending skincare techniques that promise intense hydration and a glowing complexion. But which one is right for you? Let’s break down the differences, benefits, and best practices for each method so you can find the perfect hydration strategy for your skin.
What Is Slugging?
Slugging is a K-beauty-inspired skincare technique where you apply a thick layer of occlusive moisturizer (like petroleum jelly or an oil-based balm) as the last step in your nighttime routine. This helps lock in moisture and prevent water loss, making it ideal for extremely dry or compromised skin.
🔹 Benefits of Slugging
✔ Deep hydration – Prevents moisture loss overnight
✔ Restores skin barrier – Helps repair dry, irritated skin
✔ Enhances skincare absorption – Locks in serums and creams
✔ Great for cold weather – Protects skin from dryness and windburn
🔹 How to Slug Properly
1️⃣ Cleanse your face and apply lightweight hydrating serums (like hyaluronic acid).
2️⃣ Seal everything in with a thin layer of petroleum jelly or a thick occlusive balm.
3️⃣ Leave it on overnight and rinse off in the morning.
💡 Best for: Very dry, sensitive, or compromised skin (eczema-prone or post-tretinoin users).
🚨 Not ideal for: Acne-prone or oily skin—the thick occlusive layer can clog pores.
What Is Skin Flooding?
Skin flooding is all about layering lightweight, hydrating ingredients (like hyaluronic acid, glycerin, and ceramides) onto damp skin to maximize absorption. This method focuses on water-based hydration rather than oil-based occlusives.
🔹 Benefits of Skin Flooding
✔ Lightweight but deeply hydrating – Great for everyday moisture boost
✔ Absorbs quickly – Doesn’t feel greasy or heavy
✔ Balances hydration levels – Ideal for dehydrated, dull skin
✔ Works well under makeup – Leaves skin plump and smooth
🔹 How to Do Skin Flooding
1️⃣ Start on damp skin – Apply products right after cleansing to help lock in water.
2️⃣ Layer hydrating serums – Use hyaluronic acid, glycerin, and niacinamide.
3️⃣ Seal with a moisturizer – Use a lightweight gel or cream to lock everything in.
4️⃣ Apply SPF in the morning – If done in the AM, always finish with sunscreen.
💡 Best for: Dehydrated, combination, or normal skin types looking for a lightweight but effective hydration boost.
🚨 Not ideal for: Severely dry or compromised skin—this method hydrates but doesn’t seal in moisture as well as slugging.
