Drinking Olive Oil for "Glass Skin"? Inside Korea's Viral K-Wellness Obsession

Over the past few months, extra virgin olive oil has transformed into Korea’s latest Korean olive oil trend—sold in small stick-pouches like ginseng extract, pre-mixed with lemon juice or tomato juice, and marketed as a "viral revolutionary discovery" for glass skin and inner beauty. The basic health benefits of healthy fats are real, but the framing is pure marketing strategy. Most of the oil is simply imported Spanish cooking oil. Here is a look from Seoul at what the Korean olive oil trend actually is, what the quality numbers on the label mean, and how to look at it sensibly.

For most of the last decade, when the beauty industry talked about Korea, it meant skincare...

Over the past several months, extra virgin olive oil has become one of Korea’s buzziest ingestible-wellness products. But it isn't sitting in a glass bottle by the stove—people are drinking it straight.

The format is key. Instead of standard kitchen bottles, olive oil now comes in capsules, single-serve sachets, and stick-pouches—the exact same packaging Korea uses for red ginseng extract, hangover tonics, and vitamin syrups. Brands building their identity around "inner beauty" sell an olive oil shot paired with lemon juice or tomato juice, dosed like a daily supplement: one pouch every morning on an empty stomach.

The claims on social media are high. Influencers—mostly skincare influencers—credit the daily olive oil shot with clearer skin, fewer breakouts, and a glowing "glass skin" look from the inside out. The versions mixed with lemon juice or tomato juice come with scientific-sounding justifications:

• Lemon juice: Cuts the heavy feel of the oil and adds vitamin C for collagen support.

• Tomato juice: Provides lycopene, an antioxidant that fat helps the body absorb.
  
  

None of this is new science. Drizzling olive oil over tomatoes is lunch. Adding lemon juice to olive oil is salad dressing. Countries across the Mediterranean—Spain, Greece, Italy—have been pairing fat with tomatoes for centuries simply because it tastes good. What’s clever here isn’t a new discovery. It’s the packaging.

When I started looking into the sourcing, I was curious where all this extra virgin olive oil was coming from. Turns out, it is mostly Spanish oil: Spanish Picual, Spanish Arbequina, and Spanish cold-pressed oils. Some brands even sell dual-pack sachets where both the olive oil and the concentrated lemon juice come from Spain.

This makes sense because Korea has no local olive oil production, so everything must be imported. But a Korean olive oil trend presented as a new Asian wellness secret relies on the exact same Mediterranean oil that people in Europe use for basic cooking every day.

The reliance on Spanish oil comes down to production scale. Spain produces roughly 38% of the world’s olive oil supply—several times more than Italy or Greece—and exports it at lower wholesale prices. For any company buying oil in bulk to package into sachets, Spain is the obvious choice for reliable, cost-effective supply. Brands buy standard global commodity oil at commodity prices, put it in a sleek pouch, and sell it back as a luxury K-wellness supplement dose.

Here is what that number means in simple terms:

• What it measures: Acidity in olive oil isn't about sour taste. It measures free fatty acids, showing how fresh the olives were when pressed. Lower is better.

• Legal limits: To be labeled Extra Virgin, international rules set the ceiling at 0.8%. Standard "virgin" oil goes up to 2.0%.

• The baseline: Good producers regularly achieve between 0.1% and 0.3%.
  
  

A sachet claiming 0.18% olive oil acidity is using a good number. But that number is standard for almost any decent bottle of Spanish extra virgin olive oil on a supermarket shelf. The acidity spec being presented as an elite wellness credential is just the normal baseline for good bottled oil, repriced inside a sachet.

The real shift here is psychological.

Pouring olive oil over pasta or a salad feels like meal prep; it’s familiar and ordinary. But tearing open a measured stick-pouch and swallowing it at 7:00 AM on an empty stomach feels like a deliberate health practice. It fits what Korean wellness culture values: precision and effort.

Putting extra virgin olive oil into the same stick-pouch as traditional herbal extracts shifts the product out of the kitchen category and into the inner beauty Korea category. The consumer taking the sachet doesn't feel like they are drinking cooking oil; they feel like they are taking a functional skin supplement. Same oil, different perception.

Extra virgin olive oil is healthy. It is a monounsaturated fat with well-documented anti-inflammatory properties and clear heart health benefits when eaten as part of a balanced diet.

However, medical professionals clarify that drinking it as a shot offers no unique advantages over eating it with food:

• For skin benefits: Medical insights from The Educated Patient point out that skin health improvements come from overall habits like hydration, balanced nutrition, and consistency, rather than drinking oil shots.

• For digestive health: Gastrointestinal experts interviewed by TODAY note that there is no clinical evidence showing olive oil and lemon juice on an empty stomach do anything unique for digestion, as the digestive tract processes fat the same way regardless of timing.
  
  

There is also a basic nutritional reality to keep in mind: olive oil helps the body absorb fat-soluble vitamins (A, D, E, K) and antioxidants when eaten alongside other food, like vegetables. Drinking plain oil in a sachet misses that dietary benefit entirely.

A single tablespoon of olive oil contains roughly 120 calories of pure fat. Adding multiple daily shots on top of normal meals adds extra calories quickly. Buying olive oil in sachet format is also significantly more expensive per milliliter than buying a high-grade bottle from a store.

It’s surreal to walk through Seoul and see basic cooking oil packaged like a clinical beauty tonic. Korea hasn't discovered new medical properties in olive oil that were missing for generations. What Korea has done is take an imported food staple and turn it into a sleek, packaged daily habit for people who might not otherwise consume it.

Good extra virgin olive oil is great for you. But it doesn't need a single-serve sachet or a "glass skin" promise to be worth buying. You get the exact same health benefits—and much better food—by keeping a good bottle next to your stove and using it on your plate.
