Today, we see many Western beauty products are derived from Korean skincare that have meticulous multi-step skincare rituals. With the rise of K-beauty, their exceptional serums continued on dominating the beauty and dermatology industry worldwide.
Serums are the next step essential in your skincare and should be used after cleansing and before moisturizing. Consists of smaller molecules, they have concentrated “actives”, made in clear, gel-like solutions applied to the skin. This means that they are absorbed quickly and penetrate deep into the skin.
But, what if you have oily skin? Do you know that you also need serums to avoid the overproduction of sebum which results in oilier skin? If you’re searching for the best Korean serum for oily skin, our team provided this article with all of the basic information and in-depth research about the top-rated serums in the market.
Important Factors to Consider
Formula and Skin Types
Unlike moisturizers which have larger molecules, serums are mostly water-based and able to hydrate and nourish the skin deeply. They do not contain occlusive, moisturizing ingredients like petrolatum or mineral oil. They have a high concentration of active ingredients such as antioxidants, vitamins, peptides, and brightening agents.
Facial serums are used to treat a multitude of skin problems such as dryness, fine lines, wrinkles, dark spots, uneven skin tone, large pores, acne, and premature skin aging. Generally, they are good for all skin types. So, it all goes down to your choice of serum which largely depends on your personal needs or skin concern that you want to address:
- For people who have mature skin, use antioxidant serums with higher amounts of vitamins and minerals, ferulic acid, and resveratrol can be specifically useful to fight free radical damage.
- For those who have dry and flaky skin, use hydrating serum with hyaluronic acid or vitamin E, and powerful plant water extracts that contain high capacity of retaining hydration.
- For people who suffer in large pores and oily skin, you can use serums with Vitamin C, niacinamide, and zinc. You can also use serums with exfoliants particularly BHA and LHA. These compounds unclog pores and deep cleanse the skin to minimize sebum production and large pores.
- For people who have combination skin (oily T-zone areas and dry U-zone areas in the face), use hydrating serum that has light consistency. Try serums with hyaluronic acid for deep hydration and plant extracts that are soothing, calming, and able to decrease the production of natural oils or sebum.
- For those who have sensitive skin, you need calming and restoring serums that contain ingredients like Vitamin B5 which can soothe the skin and promote healthy barrier function.
- For those who have dull or hyperpigmented skin, exfoliating serums that also have hydrating and soothing properties are your face heroes! Look for exfoliants in the ingredients list specifically AHA and PHA to remove and shed dead skin cells and reveal new, glowing skin.

In this section, we provide you the most common questions along with the corresponding answers that people have about Korean serums.
What Does a Korean Serum Do For Skin?
Similar to the Western serums, Korean serums are concentrated skin treatments that don’t contain fillers like emulsifiers or emollients that cleansers and moisturizers do. So the actives can get to your skin faster. Like what have mentioned earlier, serums have smaller molecules of active ingredients as they are made to heal your particular skin concerns.
How Does Serum Differ from Essence, Boosters, and Ampoule?
Actually, they have the same purpose which is to target your skin concern with concentrated actives and nourishing ingredients. But in Korea, there are two types of essence: first essences and treatment essences. First essences have water-like consistency and fall on the pre-toning stages as your first step in the hydration process. On the contrary, those products that are labeled treatment essences are basically serums that treat your skin problems such as hyperpigmentation, fine lines, large pores, etc.
Ampoules and boosters are commonly known to have higher concentration of serum but it really depends on how the product itself is formulated. So, it really depends on how the brands market their products. You need to check the label properly and the product’s usage.
What Type of Serum is Best for Oily Skin?
The goal for oily skin is to balance water and oil production. Search for ingredients that offer hydration, pore minimizing, and exfoliating properties. For deep hydration, search for hyaluronic acid, panthenol, and plant water extracts. If you need exfoliation, find chemical acids like AHA, BHA, PHA, and LHA.
Search for niacinamide and zinc if you have large pores and oily skin. Find plant seed oils rich in linoleic acid or Omega-6 fatty acid that are rich in antioxidants and anti-inflammatory properties, great for all skin types especially dehydrated skin. Some examples of these plant seed oils are rosehip seed oil, hemp seed oil, grapeseed oil, and many more.
Is It Alright To Use More than One Serum, Ampoule, or Booster at the Same Time?
Based on the website by Klog, it is safe and ok to layer your serums or add an ampoule to your usual skin care routine for an extra boost. For extra glowing makeup, you can add a drop of serum to your foundation right before you apply it. Remember, it depends on how much you mix in, your foundation’s consistency might change, so mix carefully.
How Long Does It Take To Notice the Results After Using the Serums?
It takes about four weeks to see results from using serums. Less than 28 days, some people can see results. But if you want to give a new serum one more chance, give it a month. After all, even though the treatment is concentrated, it won’t change the rate your skin cells turn over. Also, each one of us has his own particular skin structure and type. Please cultivate patience while using serums.
Therefore, having serums in your skincare routine is all about customizing your routine to your time needs as well as your skin’s needs. If you’re limited in the amount of time that you have, you can apply one serum in the day time and one in the evening. If you have a busy morning, apply once in the morning and at night.
For your self-care, this is a healing personalized step that will allow you to achieve your skincare goals and not take up too much time. Most significantly, serums are fundamental to your skincare game whatever skin type you have.
