Slugging Skincare Trend: Does It Really Work?

If you’ve spent time on beauty TikToks or Instagram lately, you’ve likely come across the viral trend known as slugging skincare. The glossy, glazed effect might look dramatic, but the idea behind it is simple: lock in moisture and repair your skin barrier using an occlusive layer overnight.

But the big question remains: Does slugging actually work—and is it right for your skin?

Here’s an expert-backed breakdown of what slugging is, who benefits most, and how to do it safely with products available on SkincareEssentials.com.

Slugging is a skincare technique where you apply a thick occlusive product—traditionally petroleum jelly—over your nighttime moisturizer. This creates a protective barrier that prevents water loss and boosts overnight healing.

Dermatologists refer to this process as transepidermal water loss prevention, and it’s especially helpful for repairing a compromised or dry skin barrier.

Yes—when used correctly, slugging can dramatically improve hydration, smoothness, and overall skin comfort.

It works by:

• Locking in moisture

• Protecting the skin barrier

• Helping hydrating ingredients work more effectively

• Reducing irritation from retinoids or exfoliants (when used on non-active nights)

• Improving the appearance of flakiness and dryness overnight

However, it’s not for everyone, and it shouldn’t be used every night.

Slugging is ideal for:

• Dry skin

• Dehydrated skin needing barrier repair

• Sensitive or irritated skin

• Winter or cold climates

• Retinol or exfoliant users experiencing dryness

It’s also great for “rescue nights” when your skin feels tight or compromised.

Slugging is not recommended for:

• Oily skin

• Acne-prone skin

• Skin easily congested or prone to blackheads

• Humid climates

Occlusives can trap oil and bacteria, which may worsen breakouts. If this sounds like you, a lighter barrier cream is a better option.

1. Cleanse thoroughly

Make sure your skin is completely clean to avoid trapping impurities.

2. Apply hydrating layers

Slugging works best when paired with humectants like hyaluronic acid.

Top picks:

• SkinMedica HA5 Rejuvenating Hydrator – perfect for attracting and holding moisture

• Image Skincare Vital C Hydrating Anti-Aging Serum – brightens while boosting hydration

3. Add your moisturizer

Choose a nourishing cream before sealing everything in.

Great options:

• SkinMedica Dermal Repair Cream – deeply moisturizing and barrier-supportive

• Image Skincare Ormedic Balancing Bio-Peptide Crème – gentle, nourishing, ideal for sensitive skin

4. Seal with an occlusive

This is the slugging step. Apply a thin layer of an occlusive balm, such as a petroleum jelly.

5. Use 1–2 nights per week

Daily slugging is usually unnecessary and may be too heavy.

Slugging works especially well on recovery nights of a skin cycling routine.

Avoid slugging on nights when you use:

• Retinoids

• AHAs/BHAs

• Vitamin C

Applying occlusives over active ingredients can irritate the skin.

After a night of slugging, many people notice:

• Softer, smoother skin

• Reduced flakiness

• A stronger, more resilient moisture barrier

• Healthier glow

• Better tolerance of active ingredients over time

Results are often visible after just one night, especially in dry winter months.

So… Does Slugging Work?

Yes—slugging works beautifully for the right skin types.

It’s one of the simplest, most effective ways to boost moisture and strengthen the skin barrier. The key is knowing how often to use it and choosing the right hydrating products to layer underneath.
