Looking for a Korean serum or ampoule that genuinely fits your skin? At YUZUM, we have brought together a carefully selected range of Korean serums and ampoules for hydration, sensitive skin, dullness, uneven-looking tone, excess oil and early signs of ageing.
Whether you want a lightweight hydrating serum for everyday use or a more concentrated ampoule for a specific concern, you can compare formulas from trusted Korean skincare brands and choose the product that makes sense for your routine. Our collection includes popular ingredients such as centella asiatica, heartleaf, hyaluronic acid, propolis, niacinamide, vitamin C, rice and alpha-arbutin.
What Is the Difference Between a Serum and an Ampoule?
Serums and ampoules are both concentrated skincare products, but they are normally used slightly differently.
A Korean serum is usually designed for regular use. It can be applied every morning, every evening or both, depending on the formula. Serums are a practical option when you want ongoing support for hydration, brightness, skin texture or general skin comfort.
A Korean ampoule is often more focused or concentrated. Some ampoules are used every day, while others can be added when your skin needs extra attention. The texture may be watery and lightweight or slightly richer, depending on the ingredients.
You do not necessarily need both in the same routine. For many people, choosing one well-matched serum or ampoule is more useful than layering several active products at once.
Choose a Korean Serum for Your Skin Concern
The best Korean serum is not simply the most popular one. It should match your skin type, main concern and the other products already in your routine.
For Dry or Dehydrated Skin
If your skin feels tight, rough or uncomfortable, look for hydrating ingredients such as hyaluronic acid, glycerin, beta-glucan, birch juice and panthenol.
A lightweight option such as the Round Lab Birch Juice Moisturizing Serum can be layered between your toner and moisturiser without making the routine feel unnecessarily heavy.
You can also explore our full skincare collection for dry skin to find compatible cleansers, toners and moisturisers.
For Sensitive or Easily Uncomfortable Skin
When your skin is sensitive, a simple formula is often a better starting point than a routine containing several strong active ingredients.
Ingredients such as centella asiatica, heartleaf, green tea and panthenol are frequently chosen for routines focused on hydration and skin comfort. Popular options in this collection include:
- ANUA Heartleaf 80% Moisture Soothing Ampoule
- SKIN1004 Madagascar Centella Ampoule
- Beauty of Joseon Calming Serum Green Tea + Panthenol
Always check the complete ingredient list and introduce one new product at a time, particularly when your skin is reactive. Our sensitive-skin collection contains more products selected for gentle and uncomplicated routines.
For Dull or Uneven-Looking Skin
For a brighter and more even-looking complexion, consider ingredients such as vitamin C, niacinamide, rice extract and alpha-arbutin.
The Beauty of Joseon Glow Deep Serum Rice + Alpha-Arbutin is an option for routines focused on dullness and uneven-looking tone.
Brightening products usually need consistent use rather than occasional application. Introduce them gradually and wear sunscreen during the day.
For Oily or Blemish-Prone Skin
Oily skin still needs hydration. Removing every moisturising product from your routine can leave the skin feeling uncomfortable and may make it harder to maintain a balanced routine.
Look for lightweight, fast-absorbing serums containing ingredients such as niacinamide, heartleaf, centella or green tea. Avoid starting several exfoliating or highly concentrated formulas at the same time.

Popular Korean Serum and Ampoule Ingredients
Understanding a few common ingredients can make choosing a product much easier.
- Hyaluronic acid: Helps support hydration and is commonly found in lightweight serums for dehydrated skin.
- Centella asiatica: Frequently used in Korean skincare formulas made for sensitive or uncomfortable skin.
- Heartleaf: A popular Korean skincare ingredient used in routines for sensitive, oily and blemish-prone skin.
- Niacinamide: A versatile ingredient used in products targeting dullness, uneven-looking tone and excess oil.
- Vitamin C: Commonly selected for brightening routines and antioxidant support.
- Propolis: Often found in nourishing and glow-focused Korean ampoules.
- Rice extract: Used in formulas intended to support hydration and a more radiant-looking complexion.
- Panthenol: A moisturising ingredient often included in products for skin comfort and barrier support.
The ingredient with the highest percentage is not automatically the best choice. The complete formulation, your skin type and how frequently you use the product all matter.
How to Use a Korean Serum or Ampoule
A serum or ampoule is normally applied after cleansing and toning but before moisturiser.
- Start with a suitable facial cleanser.
- Apply your preferred Korean toner.
- Dispense two or three drops of serum or ampoule.
- Spread the product gently across your face and neck.
- Allow it to absorb before applying a moisturiser.
- Finish your morning routine with a product from our Korean and Japanese sunscreen collection.
You do not need to use a large amount. Applying more product does not guarantee faster or better results.
When introducing vitamin C, exfoliating acids, retinoids or other active ingredients, begin slowly and monitor how your skin responds. A patch test is sensible when you have sensitive skin or known ingredient allergies.
Can You Use More Than One Serum?
Yes, but more products do not always create a better routine.
Two compatible serums may be layered when they address different needs—for example, a lightweight hydrating serum followed by a targeted brightening product. Apply the thinnest texture first and allow each layer to absorb.
However, avoid combining several strong active ingredients without understanding how they work together. When your skin becomes irritated, simplifying the routine is usually more helpful than adding another treatment.
When Should You Apply Serum?
Most hydrating and soothing serums can be used in the morning, evening or both. Some active formulas may have specific usage instructions, so always check the individual product page and packaging.
In the morning, use sunscreen as the final skincare step. At night, finish with a moisturiser that suits your skin type and the season.

Frequently Asked Questions
Is an ampoule stronger than a serum?
An ampoule is often more concentrated or focused, but this is not a universal rule. Always compare the ingredients and usage instructions of the individual products.
Do I need both a serum and an ampoule?
No. One well-chosen product may be enough. Use both only when they serve different purposes and work comfortably together in your routine.
Can I use a Korean serum every day?
Many hydrating and soothing serums are designed for daily use. More active formulas may need to be introduced gradually, depending on their instructions and your skin tolerance.
Should serum be applied before or after moisturiser?
Serum is normally applied before moisturiser. A common order is cleanser, toner, serum or ampoule, moisturiser and then sunscreen in the morning.
Which Korean serum is best for beginners?
A simple hydrating or soothing serum is often the easiest starting point. Choose according to your skin type and introduce only one new product at a time.
How long does a serum take to work?
Hydration and skin comfort may be noticeable relatively quickly, while changes in the appearance of tone or texture generally require consistent use. Results vary by formula, routine and individual skin.
