Quick Summary
Slugging became popular for protecting dry skin during cold winters, but India's climate is very different from the regions where the trend originated. In humid cities, a heavy occlusive layer may trap sweat and oil instead of preventing moisture loss. Whether slugging works depends on your skin type, the season and where you live.
What Is Slugging?
Slugging is an overnight skincare technique where a thick occlusive product, usually petroleum jelly, is applied as the final skincare step.
The purpose is simple.
Instead of adding moisture, slugging locks in the hydration already present from moisturisers and serums underneath by reducing overnight water loss.
This makes sense in dry climates where skin loses moisture quickly while you sleep.
Why Did Slugging Become Popular?
The trend gained popularity through Korean and Western skincare communities, particularly during winter.
People living in cold, dry climates often experience:
-
Tight skin
-
Flaking
-
Barrier damage
-
Increased water loss overnight
Slugging helps reduce these problems by creating a protective layer over the skin.
The important point is that slugging was designed to solve dry climate dehydration, not humidity.
Why Indian Weather Changes Everything
India does not have one climate.
The experience of someone living in Mumbai is very different from someone living in Delhi during winter.
Humidity changes how much water naturally evaporates from the skin.
When humidity is high, skin already loses less water.
Adding a thick occlusive layer may trap:
-
Sweat
-
Sebum
-
Heat
-
Product residue
rather than providing additional hydration.
This is why slugging often feels completely different in Indian summers compared with colder countries.
When Slugging Can Work Well
Slugging may still be useful in certain situations.
During North Indian Winters
Cities such as Delhi, Jaipur, Chandigarh and Lucknow experience significantly drier winter air.
Here, overnight moisture loss becomes more noticeable, making slugging more practical.
For Very Dry Skin
People with naturally dry or compromised skin barriers may benefit from occasional slugging regardless of season.
Around Dry Areas
Slugging does not have to involve the whole face.
Applying an occlusive layer to:
-
around the mouth
-
dry cheeks
-
elbows
-
hands
may provide targeted relief without covering oil-prone areas.
In Air-Conditioned Rooms
Sleeping in air-conditioned environments can lower indoor humidity even during summer.
If your bedroom remains cool and dry throughout the night, occasional slugging may still feel comfortable.
When Slugging Is Less Suitable
Slugging is usually less appropriate when:
-
humidity is very high
-
your skin is oily
-
you are prone to acne
-
your skin already feels greasy by evening
In these situations, the additional occlusive layer may feel heavy without solving a genuine hydration problem.
What About Mumbai During Monsoon?
Mumbai's climate is almost the opposite of the conditions slugging was designed for.
High humidity naturally slows moisture loss while increasing sweat and oil on the skin.
Many people therefore focus on gentle cleansing and lightweight hydration rather than sealing the skin with heavy occlusive products.

Are There Better Alternatives for Humid Weather?
Often, yes.
Instead of preventing moisture loss with a heavy occlusive layer, many people simply support the skin barrier using lighter ingredients such as:
-
ceramides
-
hyaluronic acid
-
glycerin
These ingredients help maintain hydration without creating the thick layer associated with slugging.
Many people also choose barrier-supporting cleansers that cleanse gently without leaving skin feeling tight afterwards.
Does Slugging Cause Breakouts?
Slugging itself does not directly cause acne.
However, applying a heavy occlusive layer over skin that already contains excess oil, sweat or trapped impurities may increase congestion in people who are already acne-prone.
This is why cleansing thoroughly before bedtime remains important.
Our article on Cleansing After Wearing SPF All Day explains why removing sunscreen and daily buildup is particularly important before overnight skincare.
Should You Try Slugging?
Ask yourself three questions.
-
Is my skin actually dry?
-
Is the weather currently dry?
-
Am I trying to solve dehydration rather than oiliness?
If the answer to all three is yes, slugging may be worth trying occasionally.
If your skin already feels oily or sticky before bed, it is unlikely to provide the same benefit.
Frequently Asked Questions
Does slugging work in humid Indian weather?
It can, but usually only for very dry skin. For many people, high humidity already reduces moisture loss naturally.
Is slugging good for oily skin?
Generally, oily and acne-prone skin benefits less from slugging, particularly during hot and humid months.
Can I slug during Indian summer?
For most people, it is unnecessary. Summer humidity already slows water loss from the skin.
Is slugging better in winter?
Yes.
Dry winter air creates the conditions slugging was originally designed to address.
What can I use instead of slugging?
Many people achieve comfortable hydration with lighter products containing ceramides and hyaluronic acid rather than using a fully occlusive layer.
Climate Matters More Than Trends
Slugging is neither a miracle technique nor a skincare myth. It is a method designed for a specific problem: preventing moisture loss in dry environments. Before adopting any skincare trend, consider whether your climate and skin actually match the conditions it was created for. In much of India, especially during summer and monsoon, adjusting your routine to the weather often makes more sense than following the same trend all year.
