Korean vs. Western skincare ingredients: What are the differences?

From their philosophy to their purpose and ingredients, these two cosmetic approaches are entirely distinct. Korean skincare is deeply rooted in Hanbang medicine, favoring ingredients with cultural and historical significance while emphasizing natural beauty. Western cosmetics, on the other hand, are derived from dermatology and clinical science, prioritizing efficacy and visible results with scientifically developed and tested ingredients.

While Western cosmetics often focus on potent active formulas for targeted treatments, Korean skincare ingredients tend to be gentler, emphasizing hydration and problem prevention with innovative, natural extract-based formulas. Want to learn more about them? Keep reading!

Key K-Beauty ingredients

Here are some of the most prominent ingredients in Korean skincare, found in various types of K-Beauty cosmetics, offering numerous benefits for your skin:

Centella Asiatica

Also known as Cica, Centella Asiatica is a medicinal plant rich in anti-inflammatory, antifungal, and antibacterial properties. In skincare, it soothes and treats irritated skin while stimulating collagen production—the main protein responsible for skin structure, firmness, and elasticity. You can find this ingredient in countless Korean skincare products, from creams and serums to soaps, shampoos, and even anti-cellulite products.

Snail Mucin

Who would have thought snail secretion could provide so many benefits to human skin? In addition to its hydrating, soothing, and healing properties, snail mucin helps strengthen the skin and maintain a smooth, youthful complexion. It’s featured in various products, including creams, serums, and masks.

Mugwort

Better known as an herbal infusion, mugwort, or "field chamomile," is a medicinal plant often used to treat menstrual disorders. In skincare, it’s a powerful ingredient that soothes inflammation, calms redness, and strengthens sensitive skin. It can be found in cleansers, toners, essences, and masks.

Propolis

With antibacterial and anti-inflammatory benefits, propolis is a resinous substance created by bees. It’s perfect for sensitive or acne-prone skin as it soothes and protects. You’ll find it in products like ampoules, serums, creams, and masks.

Rice water

Another natural Korean skincare ingredient, rice water brightens the skin, evens out skin tone, and hydrates while reducing irritation and combating signs of aging. It also helps regulate oil production, making it great for oily or combination skin. Rice water can be used in its natural form or found in toners, cleansers, essences, and face masks.

Standout K-Beauty ingredients

Thanks to their unique properties and visible results, some K-Beauty ingredients have gained immense popularity worldwide. Here are a few:

Ginseng

A key ingredient in Korean medicine, ginseng is a medicinal plant rich in antioxidants that rejuvenates the skin, improves elasticity, and reduces wrinkles. It’s prominently featured in anti-aging creams, serums, ampoules, masks, essences, and cleansers.

Green Tea Extract

Packed with antioxidants, green tea protects the skin from external aggressors like free radicals, soothes inflammation, and offers anti-aging benefits. You’ll find it in moisturisers, serums, masks, and more.

Hyaluronic Acid

Did you know hyaluronic acid is a molecule naturally found in our skin, connective tissues, and eyes? It’s a super hydrator that attracts and retains water molecules, keeping the skin plump and protected. One of its major advantages is that it’s suitable for all skin types. This superstar ingredient can be found in serums, toners, moisturizers, eye creams, mists, and face masks.
