Choosing a face serum: how to find a formula that suits your skin

A face serum can be a useful step between cleansing and moisturising. But choosing one isn’t always straightforward. A lightweight gel, a hydrating serum with hyaluronic acid and a retinol serum all serve different purposes. If you choose based only on words such as “glow”, “lifting” or “deep repair”, you could easily end up with a product that doesn’t suit your skin or daily routine.

Common pitfalls when choosing a face serum

1. Mistaking marketing language for verifiable product information

Terms such as “anti-wrinkle”, “firming” and “intensive repair” sound appealing, but tell you little without an ingredients list and instructions for use. Instead, look for specific details:

  • Which active ingredients are listed?
  • What concentration is stated?
  • Is the serum intended for daily use, or should you introduce it gradually?
  • How many millilitres do you actually get?

A brand’s claim about visible results is no guarantee of how your skin will respond. For example, a brand may refer to percentages or user feedback based on its own research. Treat this as brand communication, not as a promise of personal results.

2. Choosing a serum that’s too strong for a beginner routine

A retinol serum or vitamin A serum needs more consideration than a simple hydrating serum. According to product information, retinol and retinal can increase sensitivity to sunlight. So start with a small amount and use it infrequently. Apply sunscreen during the day, and don’t automatically combine several potent active ingredients while you’re building up your routine.

3. Focusing on the promise and not the texture

A serum that feels heavy, heavily fragranced or sticky may end up unused in your cupboard after a few days. Check the formula:

  • A watery or lotion-like texture often works well in a hydrating routine.
  • A gel serum can feel comfortable on normal or combination skin.
  • An oil-based formula may feel more comfortable on dry skin.
  • Fragrance and essential oils may be worth checking if you’re looking for a serum for sensitive skin.

Which specifications should you compare?

1. Active ingredients and your skin concerns

Start by deciding which concern you want to address. For dehydrated skin, glycerin, panthenol and hyaluronic acid serum formulas are useful ingredients to compare. Hyaluronic acid comes in different forms and molecular sizes. An ingredients list tells you that it’s present, but not necessarily how much difference you’ll notice.

For a duller complexion, you could look at niacinamide, alpha-arbutin or vitamin C derivatives. A brightening serum with alpha-arbutin, such as Beauty of Joseon Glow Deep Serum, is described as helping to promote a more even-looking complexion. Use sun protection during the day too, particularly if pigmentation is a concern.

If you’re focusing on fine lines or skin texture, you could consider an anti-ageing serum, retinol serum or anti-wrinkle serum. Retinol, retinal and bakuchiol are different ingredients, each with its own recommended approach to use. A more complex formula isn’t automatically a better match.

2. Skin type, tolerance and warnings

Check whether the product is described as suitable for your skin type. “For all skin types” is a broad claim, but individual tolerance varies. Patch test new products and stop using them if you experience persistent redness, itching, swelling or a burning sensation.

Instructions for use are particularly important with retinol and retinal. For example, start by using the product twice a week, and only increase this if your skin tolerates it well. Don’t use a retinol product during pregnancy or while breastfeeding unless advised by a healthcare professional, as also stated in SKIN1004’s product warning.

3. Size, packaging and shelf life

Compare more than just the price of the bottle; check the amount too. A 7, 9 or 10.5 ml serum may be intended as a targeted course or an introduction to the product, while 30, 50 or 100 ml may be more suitable for daily use.

Check the packaging as well. Capsules can provide a set amount for each application. A pump bottle may limit contact with the product. If you’re using a pipette, good hygiene is important: don’t touch your skin with it. Always check the expiry information and the period after opening on the packaging.

How to use a face serum in your routine

  1. Cleanse your face and gently pat your skin dry.
  2. Apply a few drops, unless the packaging gives a different dosage.
  3. Avoid direct contact with your eyes.
  4. Finish with a moisturiser if your skin needs one.
  5. Use sunscreen during the day, especially with retinol, retinal or other ingredients that may increase sensitivity to the sun.
  6. Don’t introduce several new active serums at the same time. This makes it easier to see which products your skin tolerates well and which it doesn’t.

Frequently asked questions about face serum

How often should you use a face serum?

It depends on the formula. A hydrating serum can often be used daily, as directed on the label. It’s best to introduce a retinol serum gradually: for example, start by using it twice a week in the evening, and only increase this if your skin tolerates it well.

How long does a face serum last?

Check the expiry date and the period after opening on the packaging. Store your serum somewhere cool and dry, away from direct sunlight. Always close a pipette or pump bottle securely. If the product changes in smell, colour or texture, stop using it.

How much does a good face serum cost?

The price depends on the brand, size, packaging and ingredients. So compare the price per millilitre and check whether the formula is suitable for daily use. A smaller retinol serum may be a good way to try one first, while a 30 to 50 ml hydrating serum is often more practical for a regular routine.
