If you’ve spent any time browsing skincare forums or Instagram, you might have come across the term slugging. It sounds a bit unusual, but it’s actually a popular and effective skincare technique that many people swear by for achieving soft, hydrated skin. So, what exactly is slugging, and should you try it? Let’s break it down in simple, everyday language.
What Does “Slugging” Mean?
Slugging is a skincare method where you apply a thick layer of an occlusive product—usually petroleum jelly or a similar heavy ointment—on top of your regular skincare routine, especially your moisturizer. The idea is to create a protective barrier that locks in moisture and prevents water loss from your skin overnight.
The name “slugging” comes from the shiny, gooey look your skin gets after applying the product, resembling the slimy trail a slug leaves behind.
Why Do People Do Slugging?
Our skin naturally loses moisture throughout the day and night. Sometimes, especially if your skin is dry, damaged, or sensitive, it can lose too much moisture, leading to dryness, irritation, or a compromised skin barrier.
Slugging helps stop this moisture loss by sealing everything in. This can be especially helpful during harsh weather, dry seasons, or if you have naturally dry skin.
By forming a protective shield on your skin, slugging:
- Prevents water from evaporating
- Allows your moisturizer to work more effectively
- Helps repair and strengthen the skin barrier
- Leaves skin feeling plump, smooth, and hydrated
How Do You Slug?
Slugging is usually done as the last step in your nighttime skincare routine. Here’s a step-by-step guide:
- Cleanse your face thoroughly to remove makeup, dirt, and impurities.
- Apply your regular skincare products like serums, treatments, and moisturizer.
- Apply a thin, even layer of petroleum jelly or an occlusive ointment on top. This is the “slugging” step.
- Go to bed and let it work overnight.
- In the morning, gently wash your face to remove the occlusive layer.
What Products Are Used for Slugging?
Petroleum jelly (such as Vaseline) is the most common and affordable product for slugging. It’s widely available, safe, and effective at sealing moisture.
There are also other occlusive balms or ointments made with ingredients like:
- Mineral oil
- Lanolin
- Beeswax
- Shea butter
But petroleum jelly remains the gold standard because it’s non-comedogenic (won’t clog pores) and hypoallergenic for most people.
Who Should Try Slugging?
Slugging can be a game-changer for:
- People with dry or flaky skin who need extra hydration and moisture retention.
- Those with compromised skin barriers due to over-exfoliation, harsh weather, or skin conditions like eczema or psoriasis.
- Anyone living in cold or dry climates where skin tends to lose moisture faster.
- People wanting to boost the effects of their nighttime skincare routine.
However, slugging isn’t for everyone.
When Should You Avoid Slugging?
Slugging isn’t ideal for people with:
- Oily or acne-prone skin since the occlusive layer can trap oil and bacteria, potentially worsening breakouts.
- Very sensitive or reactive skin that might feel clogged or irritated by heavy ointments.
- Active acne or skin infections where sealing the skin might trap irritants and bacteria.
If you’re unsure, start with a patch test and observe how your skin reacts. If your skin feels too greasy or congested, slugging might not be the best choice.
What Are the Benefits of Slugging?
Many people report noticeable improvements after adding slugging to their routine:
- Deep hydration: Your skin feels softer and more supple.
- Reduced dryness and flakiness: Especially helpful for rough patches or peeling skin.
- Faster healing: Slugging can speed up repair of minor skin damage or irritation.
- Enhanced skin barrier: Over time, your skin becomes stronger and more resilient.
- Comfort and relief: Slugging can soothe tight, itchy, or uncomfortable skin.
Is Slugging Safe?
Generally, slugging is safe for most skin types when done properly. The key is using the right product (a pure occlusive like petroleum jelly) and applying it on clean, well-moisturized skin.
Avoid layering on too much product to prevent clogged pores. Also, if you notice increased breakouts, irritation, or discomfort, discontinue slugging and consult a dermatologist.
Tips for Successful Slugging
- Always apply slugging as the last step in your nighttime routine after moisturizing.
- Use a thin layer of occlusive; more isn’t always better.
- Make sure your skin is clean and hydrated before slugging.
- Don’t slug on broken skin or open wounds without professional advice.
- If you wear makeup or sunscreen during the day, slugging isn’t necessary—it’s mainly a nighttime treatment.
- Experiment with frequency: some people slug every night, while others only do it a few times a week.
Final Thoughts
Slugging is a simple but effective skincare hack that helps lock in moisture and protect your skin’s barrier. If you struggle with dryness, irritation, or want to boost hydration overnight, slugging might be worth trying.
It’s inexpensive, easy to do, and can make a big difference in your skin’s texture and comfort. Just remember, it’s not for everyone, especially if you have oily or acne-prone skin.As with any new skincare practice, listen to your skin and adjust based on how it feels.
