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

A face serum can be a targeted addition to your daily routine. However, it’s not wise to rely solely on a striking promise or a popular ingredient. A hydrating face serum, a serum for sensitive skin or a serum for redness only works well when the formula matches your skin’s needs, your routine and your tolerance.

Common Pitfalls When Buying a Serum

1. A Long Ingredient List Doesn’t Tell You Everything

A serum packed with active ingredients may look appealing, but multiple potent ingredients can make your routine unnecessarily complicated. Particularly for sensitive or acne-prone skin, it’s wiser to introduce one new product at a time. This way, you can better gauge how your skin reacts.

Also, pay attention to where an ingredient appears on the ingredients list. A product name that includes, for example, “hyaluronic acid” doesn’t automatically mean the product consists solely or mainly of hyaluronic acid. Always check the actual ingredients on the packaging.

2. Marketing Claims Are Sometimes Taken as Guarantees

Terms like “glow”, “pore-refining” or “anti-ageing” usually describe the product’s aim, not a guaranteed result. According to a brand’s own research, certain effects may have been observed, but that information doesn’t automatically apply to every user.

A serum can make your skin feel more comfortable, smoother or better hydrated. Don’t expect a medical effect, and don’t use a serum for redness or a serum for acne-prone skin as a substitute for advice from a doctor or dermatologist.

3. The Texture Is Underestimated

A rich serum for dry skin can be pleasant when you feel tightness, but it may be less suitable if you want a light routine under make-up during the day. A watery ampoule for the face, on the other hand, can absorb quickly but often requires a moisturiser on top to lock in hydration more effectively.

Important Points to Check

1. Choose Based on Your Skin’s Needs First

  • Dry or dehydrated skin: look for glycerine, hyaluronic acid, panthenol, sodium hyaluronate and skin-identical humectants. A serum with hyaluronic acid or a hydrating face serum is then a logical starting point.
  • Sensitive skin: opt for a short, straightforward formula and test it on a small area of skin first. Centella serum and formulas with panthenol or allantoin are often chosen for a comfortable skin feel. Claims about soothing come from product descriptions and are not a medical guarantee.
  • Acne-prone or oily skin: look for a light texture and ingredients such as azelaic acid or niacinamide. A serum for redness and a serum for acne-prone skin can have different purposes, so check the full formula.
  • Dull or uneven complexion: a brightening serum with niacinamide, tranexamic acid or vitamin C derivatives may suit this need. Always use sun protection during the day.
  • Visible lines and mature skin: an anti-ageing serum may contain ingredients such as retinol, retinal, adenosine or peptides. Start gently, follow the label and combine retinoids with daily sun protection.

2. Check the Concentration, Volume and Frequency of Use

An azelaic acid serum with 10%, according to the product information from ANUA, requires gradual build-up and patch testing. Start, for example, with a small amount and a low frequency. Dryness, stinging or irritation are signs to stop or adjust your usage.

Extra caution is needed with retinol products. The product information from SKIN1004 warns of increased sensitivity to sunlight and advises against use during pregnancy or breastfeeding unless a healthcare professional advises otherwise.

Also check the volume: 30 ml is common for a concentrated serum, while 55, 95 or 100 ml can be more economical for intensive daily users. Also look at the shelf life and the period after opening on the packaging.

3. Pay Attention to the Order in Your Routine

Generally, use a face serum after cleansing and possibly after toner, but before a moisturiser. A simple routine is:

  1. Gently cleanse your face.
  2. Apply one to a few drops of serum according to the instructions for use.
  3. Allow the product to absorb briefly.
  4. Use a moisturiser.
  5. Apply sun protection in the morning.

Don’t combine multiple exfoliating or highly active serums straight away. A patch test is especially advisable with a serum for sensitive skin, azelaic acid serum, retinol or a formula with fragrance and essential oils.

Frequently Asked Questions About Face Serums

How do you apply a face serum?

First, cleanse your face, then apply a few drops of serum to the skin. Gently spread the product and finish with a moisturiser. Always follow the specific instructions on the packaging. If you’re using an active ingredient like retinol or azelaic acid, start with a low frequency.

How long does a serum last?

The shelf life varies by formula. Check the expiry date, batch information and period after opening on the packaging. Close the bottle tightly and store it according to the instructions, usually away from direct sunlight and in a cool, dry place. A change in smell, colour or texture is a reason to stop using the product.

Which serum suits sensitive skin?

Look for a straightforward formula with ingredients like glycerine, panthenol or centella, and avoid introducing multiple active products at the same time. A serum for sensitive skin should first be tested on a small area of skin. Stop if you experience persistent redness, itching, swelling or a burning sensation, and seek advice from a healthcare professional if needed.
