Choosing a Face Serum: A Practical Guide to Skin Type, Ingredients and Usage

A face serum can be a useful addition to your daily skincare routine, but a pretty label doesn't tell you everything. If you focus mainly on terms like "glow", "lifting" or "intensive repair", you could easily end up buying a product that doesn't suit your skin or meet your expectations.

Instead, pay close attention to the ingredients list, the usage instructions and the texture. That way, you can avoid using several serums at once, causing irritation, or paying for a formula you barely use.

Common Pitfalls When Choosing a Face Serum

1. A High Percentage Isn't Automatically Better

A vitamin C serum with a high percentage, or a serum for dark spots containing multiple active ingredients, might look appealing. However, a potent formula can be less suitable for sensitive skin. For example, the ANUA Azelaic Acid 10 Hyaluron Redness Soothing Serum advises you to start slowly, using it just once or twice a week. The product information also warns of potential dryness or irritation.

So don't just look at the percentage; also consider the recommended build-up of use.

2. "Hydrating" Doesn't Mean the Same for Every Skin Type

A hydrating serum might mainly contain water-binding ingredients like glycerine or hyaluronic acid. That isn't always enough if your skin also feels dry due to a weakened moisture barrier. You'll often still need a moisturiser on top to lock in hydration.

Also, pay attention to the texture. A light lotion might work better under sunscreen or make-up, whereas a richer essence can feel more comfortable on dry skin.

3. Marketing Claims Don't Replace an Ingredients List

Terms like "anti-ageing serum", "radiance-boosting serum" and "repairing" are no guarantee of a specific result. According to brands' own product information, ingredients such as retinal, niacinamide, alpha-arbutin or vitamin C can contribute to a more even-looking complexion. However, results vary from person to person.

Always check the current INCI list on the packaging. Formulas can change, and the packaging is the most up-to-date source.

Which Features Should You Check?

1. First, Define Your Skin Goal

Identify one main concern before buying a skincare serum:

  • Dry or tight-feeling skin: look for glycerine, panthenol, sodium hyaluronate, beta-glucan or ceramides.
  • Dull complexion or visible discolouration: look for niacinamide, alpha-arbutin, tranexamic acid or vitamin C derivatives.
  • Sensitive skin or visible redness: choose a simple formula without fragrance, and build up usage slowly.
  • Blemish-prone skin: niacinamide, propolis or salicylic acid appear in some formulas. Don't combine too many exfoliating ingredients at once.
  • Fine lines and texture: retinal, bakuchiol, peptides and adenosine are commonly used in anti-ageing serums. Retinal can increase sensitivity to sunlight.

2. Check the Concentration and the Frequency of Use

A percentage is only useful when you know which ingredient it refers to and how often you can use the product. For instance, Beauty Of Joseon Glow Deep Serum states 2% alpha-arbutin and also contains rice bran water, glycerine, niacinamide and panthenol. The usage instructions recommend applying it in the evening, followed by a moisturiser.

With a vitamin C serum, you also need to consider the form of vitamin C. Dr. Althea Vitamin C Boosting Serum contains 3-O-Ethyl Ascorbic Acid and ascorbic acid, among others. OGB Vitamin C Glow Serum lists 15% vitamin C in the product description. These products are therefore not directly comparable based on the word "vitamin C" alone.

3. Pay Attention to Scent, Packaging and Shelf Life

A serum in a dropper bottle requires hygienic use: don't touch the pipette directly to your skin, and close the bottle after use. Store active formulas away from direct sunlight and check the shelf-life information on the packaging.

If you're sensitive to fragrance, it's better to choose a fragrance-free formula. When trying a new serum, do a patch test on a small area of skin first. Stop if you experience persistent redness, itching, swelling or a burning sensation, and seek advice from a doctor or pharmacist if needed.

How to Use a Serum in Your Routine

  1. Cleanse your face with a product your skin tolerates well.
  2. Apply toner or essence if you use them.
  3. Use two to a few drops of face serum on slightly damp skin.
  4. Finish with a moisturiser.
  5. Always use sunscreen during the day, especially with vitamin C, retinal, acids or a serum for dark spots.

Don't introduce several new products at once. Add one formula and observe how your skin reacts. A serum for sensitive skin isn't automatically suitable if you're allergic to a specific ingredient.

Frequently Asked Questions About Face Serums

How often should you use a face serum?

That depends on the formula. A hydrating serum can often be used daily, whereas azelaic acid, retinal or exfoliating ingredients are better introduced slowly. Follow the product packaging and reduce the frequency if irritation occurs.

Can I use vitamin C serum and niacinamide serum together?

This is possible with many modern formulas, but check the full ingredients list and your skin's reaction. It's best to start with one product at a time. Use sunscreen during the day; vitamin C does not replace sun protection.

How long does a face serum last?

Check the expiry date, the symbol for the period after opening and the storage instructions on the packaging. Close the bottle properly and store it away from direct sunlight. A change in smell, colour or texture could be a reason to stop using the product.
