Slugging has been all over social media for the past few years. The idea is simple: apply a thin layer of petroleum jelly as the last step in your nighttime skincare routine. The jelly seals in moisture while you sleep. If you have mature skin and you are wondering if this slugging skincare trend works for aging skin, the short answer is yes, with a few things to keep in mind.
What Is Slugging and Why Does It Work for Skin Over 40
Slugging gets its name from the shiny, slug-like look your skin has after you apply petroleum jelly. The technique started in Korean skincare and went mainstream on TikTok. According to Cleveland Clinic dermatologist Dr. Amy Kassouf, petroleum jelly is an occlusive ointment that forms a protective layer on the surface of your skin. That layer helps seal in hydration and keeps your skin from drying out overnight.
For women over 40, that matters. As skin matures, it loses moisture faster. Hormonal changes during perimenopause and menopause can make dryness, crepey texture, and fine lines more noticeable. The Vaseline slugging benefits for mature skin come down to petroleum jelly skin barrier repair. When you lock in your nighttime products with an occlusive layer, you help your skin hold onto moisture instead of losing it while you sleep. Dr. Kassouf notes that the retained hydration can fill the outer layers of skin, making it more pliable and elastic.
Is Slugging for Mature Skin Over 40 Safe
In general, slugging tends to be a good fit for mature skin. Dry, dehydrated skin benefits the most. However, Dr. Kassouf advises against slugging if your skin is oily, acne-prone, or if you have any open wounds or infections.
You should also avoid slugging over strong active ingredients like retinol, AHAs, or BHAs. The petroleum jelly traps those ingredients against your skin, which can make them more irritating. Gentle, non-irritating products work best underneath your occlusive.
If you are looking for the best occlusive for mature skin slugging, plain petroleum jelly (like Vaseline) is the simplest option. Aquaphor is another choice, though it contains additional ingredients like lanolin that some people may be sensitive to.
How Do You Set Up an Overnight Slugging Routine
Building an overnight slugging routine is simpler than most skincare trends. Here is how to do it:
Step 1: Cleanse your face
Slugging should only go on clean skin. Remove all makeup, sunscreen, and buildup from the day.
Step 2: Apply your skincare products
Layer from lightest to heaviest. Start with serums, then follow with your moisturizer.
Step 3: Apply a thin layer of petroleum jelly
You do not need a thick coat. A small amount on the driest areas of your face, like your cheeks and forehead, is plenty.
Step 4: Wait about 30 minutes before bed
Give everything time to settle. A towel over your pillowcase can protect your bedding.
Step 5: Wash your face in the morning
Use a gentle cleanser to remove the petroleum jelly and anything that stuck to it overnight.
You do not need to slug every single night. Dr. Kassouf says a couple nights in a row can help if your skin is very dry, but it rarely needs to be a nightly habit.
What Should You Layer Under the Petroleum Jelly
The products you apply before slugging matter more than the petroleum jelly itself. Slugging locks in whatever is underneath, so you want gentle, hydrating products that will not irritate your skin when sealed in.
Fièra's Bakuchiol Rejuvenating Facial Treatment is a retinol alternative that uses bakuchiol, a plant-based ingredient, to visibly smooth fine lines and wrinkles. Unlike retinol, bakuchiol does not increase sun sensitivity and tends to cause less peeling and irritation. That makes it a solid choice for layering under an occlusive. The treatment also contains squalane and hyaluronic acid for hydration, plus licorice root to help with the appearance of dark spots. Follow it with your moisturizer, then seal with petroleum jelly.
Can You Slug the Eye and Neck Area Too
The skin around your eyes and on your neck is thinner and tends to show signs of aging faster. You can apply a small amount of petroleum jelly around the eye area after your eye cream. Fièra's Bakuchiol Firming Eye Cream uses bakuchiol and coffee seed extract to visibly reduce fine lines, puffiness, and dark circles. It was formulated for the needs of 40+ skin, and applying a touch of petroleum jelly over it at night could help lock that hydration in place.
For your neck and chest, slugging can feel heavy. A lighter approach works better. Fièra's Néckligée™ Firming Neck & Chest Cream contains a ceramide complex, ectoin, and vitamin C to support firmness and hydration on the neck and décolletage. The whipped texture absorbs quickly and is not greasy or sticky, so it provides barrier support without the heaviness of petroleum jelly.
What to Watch for With Slugging Before and After Over 40
Most women who try slugging for mature skin over 40 notice softer, smoother skin the next morning. Fine lines can look less visible when skin is properly hydrated, and makeup often applies more smoothly on well-moisturized skin.
Slugging is a hydration technique. It helps your skin hold onto moisture, but it does not replace targeted treatments for firmness, dark spots, or crepey texture. Using good products underneath the occlusive, paired with a consistent daytime routine (serum, moisturizer, and SPF), gives you the best chance of seeing results over time.
Frequently Asked Questions
Q. How often should women over 40 try slugging?
A few times per week is a good starting point. Dr. Kassouf says a couple nights in a row can help if your skin is very dry, but most people do not need to slug every night. Listen to what your skin tells you.
Q. Can slugging clog pores on mature skin?
Petroleum jelly itself is not likely to clog pores, but it can trap dirt or other residue underneath. Cleansing your face thoroughly before slugging helps prevent breakouts. Women with acne-prone skin should avoid slugging.
Q. Is petroleum jelly the only product you can use for slugging?
Petroleum jelly (like Vaseline) is the most common option. Aquaphor and CeraVe healing ointment are alternatives. Dr. Kassouf recommends using pure petroleum jelly or products with minimal additional ingredients.
Q. Can slugging help with crepey skin on the neck?
The neck can benefit from extra hydration, but petroleum jelly may feel too heavy there. A ceramide-rich neck cream like Fièra's Néckligée™ Firming Neck & Chest Cream gives barrier support with a lighter, more comfortable texture.
