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

A face serum can be a useful addition to a simple skincare routine. Serums often contain a higher concentration of certain ingredients than a day or night cream. That doesn’t automatically mean every serum will suit your skin. The wrong combination can cause tightness, redness or flaking, particularly if you have sensitive skin.

The product name doesn’t tell you everything, either. Terms such as anti-ageing serum, brightening serum and spot treatment serum usually describe what a product is designed to do, rather than how your skin will react to it. So check the ingredients list, directions for use and any warnings.

Three common pitfalls when choosing a serum

1. Using too many active ingredients at once

Combining an exfoliating serum containing AHA, BHA or PHA with a retinoid or azelaic acid serum may be too intense for some skin types. It’s better to start with one active product and use it according to the instructions on the packaging.

2. Mistaking marketing claims for guaranteed results

A brand may state, based on its own research or product information, that a serum visibly reduces wrinkles, dark spots or redness. This doesn’t guarantee the same results for everyone. Skin type, frequency of use and daily sun exposure all play a part. Treat claims as information from the brand and compare them with the product’s objective ingredients.

3. Forgetting your skin barrier and sun protection

Sun protection is especially important when using a serum for dark spots or an exfoliating serum. During the day, use a sunscreen product according to the directions on the label. If you experience irritation, a burning sensation or swelling, stop using the product. Don’t apply an active serum to damaged or sunburnt skin.

What to look for when buying a face serum

1. Choose based on your skin concern, not the brand name

Use this guide as a starting point:

  • Dry or tight-feeling skin: look for a hydrating serum containing ingredients such as glycerine or hyaluronic acid.
  • Dull complexion and uneven texture: a brightening serum may contain ingredients such as niacinamide, vitamin C derivatives or mild acids.
  • Blemishes: a spot treatment serum sometimes contains salicylic acid or other exfoliating ingredients.
  • Redness or sensitive skin: look for a short, straightforward ingredients list and soothing ingredients such as panthenol, allantoin or centella.
  • Wrinkles and mature skin: look for hydrating ingredients, peptides or retinoids. This category calls for extra care when building up use and using sun protection.
  • Dark spots: check that the serum contains ingredients that fit your routine, and avoid layering several intensive treatments.

2. Check the INCI list

Ingredients are listed in descending order by quantity, although there are exceptions for ingredients present in low concentrations. With an azelaic acid serum, it’s worth checking the percentage stated. For example, the SKIN1004 Madagascar Centella Azelaic Acid 10 Ampoule lists 10% azelaic acid, along with ingredients including panthenol, allantoin, glycerine, sodium hyaluronate and centella asiatica.

Also look out for potential concerns:

  • Fragrance and fragrance allergens such as limonene or linalool may cause sensitivity for some people.
  • Alcohol may feel less comfortable on dry or sensitive skin.
  • Retinoids need to be introduced gradually, with extra care around sun exposure.
  • AHA, BHA and PHA can make your skin more sensitive to the sun.
  • Always check the full ingredients list on the packaging, especially if you have any known allergies.

3. Consider the size, amount to use and ease of use

A small bottle with a high concentration may last longer than a larger product that you need to use more of. Check the recommended amount: some serums are applied in a few drops, while others need one or two pumps.

A formula that’s easy to fit into your routine is more likely to be used consistently. Usually, apply a serum after cleansing and before moisturiser, unless the manufacturer advises a different order. If you have sensitive skin, test a small amount on a less visible area first.

Frequently asked questions about face serums

How do you use a face serum?

First cleanse your skin, then apply a small amount of serum. Follow the product instructions for the exact amount to use. Finish with a moisturiser. If you use the serum during the day, apply sun protection if this is recommended for the formula.

How long does a serum last?

It depends on the size, amount used and frequency of use. A 30 ml bottle may last from several weeks to a few months with daily use. Check the expiry information and the period after opening on the packaging. Store the product in a cool, dry place away from direct sunlight if instructed by the manufacturer.

Can you combine several serums?

Sometimes, but don’t combine several strong active ingredients straight away. For example, don’t use a retinol serum, exfoliating serum and azelaic acid serum together without building up gradually. Introduce one product at a time, pay attention to how your skin reacts, and consult a doctor or pharmacist if irritation persists.
