How to Slug with Korean Skincare

Introduction to Slugging

Slugging has taken the skincare world by storm, but what exactly is it? Originating from the Korean beauty (K-beauty) routine, slugging involves applying a heavy, occlusive layer as the final step in your nighttime skincare regimen. This layer helps to lock in moisture and enhance the effectiveness of the products underneath. The term "slugging" comes from the resemblance to the shiny, mucous-like trail left by a slug, reflecting the dewy glow it imparts to your skin.

Benefits of Slugging

Hydration Boost

Slugging provides an intense hydration boost by preventing water loss from your skin overnight. This is particularly beneficial for those with dry or dehydrated skin, as it ensures that your skin remains plump and moisturized.

Skin Barrier Repair

Regular slugging can aid in repairing the skin barrier, which is crucial for maintaining healthy skin. A strong skin barrier protects against environmental aggressors, reduces sensitivity, and helps retain moisture.

Enhanced Product Absorption

By sealing in your skincare products with an occlusive layer, slugging enhances their absorption and efficacy. This means that your serums, essences, and moisturizers can work more effectively, leading to better overall results.

Essential Korean Skincare Products for Slugging


Start your slugging routine with a thorough double cleanse to melt away makeup and impurities and thoroughly remove dirt, leaving your skin clean and ready for the next steps.


A hydrating toner is essential for preparing your skin. Toners balance your skin’s pH level and provides a layer of hydration that helps subsequent products absorb better.


Essences are a staple in Korean skincare routines. Use ones that are enriched with ingredients that boost hydration and improve skin texture, making it an excellent choice for slugging.


Serums are packed with active ingredients. Choose a serum that is lightweight with deeply hydrating, and soothing benefits to the skin.


A good moisturizer locks in hydration and nourishes the skin. Any moisturizer will do, to keep your skin supple and bouncy.


The final and most crucial step in slugging is the occlusive layer. Use a Sleeping Mask which forms a protective barrier that locks in moisture while you sleep, leaving your skin radiant and hydrated by morning. If you do not have a sleeping mask, you can use a thin layer of Vaseline.

Tips and Tricks for Effective Slugging

Best Practices for Different Skin Types

  • Dry Skin: Slugging is particularly beneficial for dry skin. Ensure you use hydrating and nourishing products before applying the occlusive layer.
  • Oily Skin: Use lighter, non-comedogenic products to avoid clogging pores. Slugging can still be beneficial, but it should be done sparingly.
  • Sensitive Skin: Opt for products with soothing ingredients to avoid irritation. Perform a patch test before slugging to ensure your skin tolerates the occlusive layer.

Common Mistakes to Avoid

  • Using Too Much Product: Apply products in moderation to prevent your skin from feeling too heavy or greasy.
  • Skipping Steps: Each step in your skincare routine is crucial for effective slugging. Don’t skip cleansing or moisturizing.
  • Inconsistent Routine: Consistency is key. Regular slugging yields better results over time.

How Often to Slug

  • For dry or dehydrated skin, slugging can be done 2-3 times a week.
  • For oily or combination skin, limit slugging to once a week to prevent potential breakouts.


Is slugging suitable for oily skin? Yes, slugging can be suitable for oily skin, but it's important to use lighter, non-comedogenic products and limit the frequency to prevent clogged pores.

Can slugging cause breakouts? Slugging can cause breakouts if done too frequently or if heavy, pore-clogging products are used. Always choose products that suit your skin type.

How often should I slug? For most skin types, 1-3 times a week is sufficient. Adjust the frequency based on your skin's needs and response.

Can I slug with any skincare products? It's best to use products that are hydrating and non-irritating. Avoid products with active ingredients like retinol or exfoliating acids during slugging.

What is the best time to slug? Slugging is most effective when done at night, allowing your skin to repair and regenerate while you sleep.
