Choosing a serum for spots and pigmentation: how to compare ingredients and formulas

Spots, redness and pigmentation don’t always call for the same product. A serum for spots and pigmentation can address several skin concerns, but the formula needs to suit your skin type and routine. This is especially important if you have oily, combination or sensitive skin: don’t take marketing claims at face value.

Common pitfalls when choosing a serum for acne and pigmentation

1. Using too many active ingredients at once

A serum containing niacinamide, tranexamic acid, acids, vitamin C and azelaic acid might sound appealing, but several potent ingredients can upset your skin. This is particularly true if you also use an exfoliant or retinoid. Start with one targeted formula, and only consider adding a second product later.

2. A higher percentage doesn’t automatically make it a better choice

A 10% niacinamide serum or a 10% azelaic acid serum may suit certain routines, but concentration isn’t everything. The overall formula, texture and frequency of use all affect how comfortable a serum feels on your skin. If you have sensitive skin, it’s often wiser to introduce a product gradually than to apply a lot every day.

3. Claims about results can sometimes be interpreted too broadly

Words such as “brightening”, “pore-refining” and “soothing” describe what a product aims to do, not a guaranteed result. According to some brands’ product descriptions, centella asiatica may help skin feel more comfortable, while tea tree and niacinamide are often chosen for blemish-prone skin. If you experience persistent irritation, swelling or a strong burning sensation, stop using the product and seek professional advice.

Which specifications matter?

1. Look at the key active ingredients

Choose an ingredient based on your main skin concern:

  • Azelaic acid: worth considering in a serum for blemish-prone skin, visible redness and uneven-looking skin tone. According to its ingredients list, the SKIN1004 Madagascar Centella Azelaic Acid 10 Ampoule contains 10% azelaic acid.
  • Niacinamide: often used in a facial serum for acne, for shiny skin and to help create a more even-looking skin tone. Check the percentage and look out for other ingredients too.
  • Tranexamic acid: a commonly used ingredient in serums for pigmentation and post-acne discolouration. The Anua formula lists 4% tranexamic acid.
  • Tea tree and centella: options for anyone looking for a serum for redness or a centella ampoule. Skin reactions vary from person to person; tea tree may not suit some people with sensitive skin.
  • AHA and BHA: used for surface exfoliation and blocked pores. Take care when combining these acids with other active products.

2. Check the full INCI list

A short product name doesn’t tell you whether a formula is right for you. Check the packaging for fragrance, alcohol, oils and any ingredients you’ve reacted to before. Also check the period after opening, batch information and storage instructions.

Cosmetics sold on the EU market should include an ingredients list, directions for use and details of the responsible person on the packaging, among other information. Always check the current packaging, as ingredients can change.

3. Consider the texture, size and frequency of use

A watery ampoule can sit comfortably under a moisturiser, while a richer serum may suit drier skin better. A 30 ml bottle is handy for everyday use; a 9 or 15 ml size can be a good way to try a formula first.

Apply a new product to a small area of skin first. Use active serums according to the product instructions, avoid applying them to damaged skin and wear sun protection during the day. This is particularly important if you’re addressing visible pigmentation or using a serum for acne scars.

Tips for using your serum

  1. Gently cleanse your face and apply the serum to dry or slightly damp skin, depending on the directions for use.
  2. Start with a small amount. One to a few drops is often enough for an active serum.
  3. Don’t combine several exfoliating products straight away.
  4. Finish with a moisturiser. Wear sun protection during the day, especially if your routine targets pigmentation.
  5. Store the product in a cool, dry place away from direct sunlight. Check the expiry date and the period after opening.

Frequently asked questions

Which serum is suitable for both spots and pigmentation?

It depends on your priority. A formula with niacinamide may suit oily or combination skin. Azelaic acid is often chosen for blemishes and visible redness, while tranexamic acid is worth considering for uneven skin tone. Ideally, start with one key active ingredient.

Can I use a serum for acne scars every day?

Follow the instructions on the packaging. Some serums are suitable for daily use, but it may be best to introduce active formulas gradually. Test the product on a small area of skin first and stop if irritation persists.

How long does a serum last?

It depends on the size, how often you use it and whether you apply it to your whole face or just problem areas. A 30 ml bottle will generally last longer than a mini size with daily use, but always check the recommended amount and the period after opening.
