Choosing a Face Serum: How to Find a Formula That Suits Your Skin

A face serum can be a targeted addition to your daily routine. Yet it can be tricky to choose the right one from among a vitamin C serum, niacinamide serum, hydrating serum and Korean skincare serum. A high concentration, eye-catching packaging or a promise of an even complexion doesn’t automatically mean the product is right for your skin.

Pay particular attention to three common pitfalls:

• Too many active ingredients at once: a serum with vitamin C, acids, retinoids and several plant extracts may seem comprehensive, but it can be uncomfortable for sensitive skin.
• Marketing claims without clear context: terms like “brightening” or “lifting” describe a cosmetic goal, not a guaranteed result. What’s more, effects may have been measured under specific conditions according to a brand’s own research.
• No consideration of usage and shelf life: a retinal serum is typically used differently from a hyaluronic acid serum. Exposure to light, heat and air can also affect the formula. Always check the packaging and the instructions for use.

Which Features Should You Check?

1. Look at the Key Ingredient

Start with one clear skin concern. The ingredients list helps make product information verifiable:

• Hydration: glycerin, panthenol, beta-glucan, squalane and sodium hyaluronate are common in a hydrating serum or hyaluronic acid serum.
• A more even complexion: niacinamide, alpha-arbutin, tranexamic acid and vitamin C derivatives are often used in products for a dark spot serum or a serum for an even skin tone.
• Texture and fine lines: retinal, retinol, peptides and bakuchiol are ingredients suited to a cosmetic anti-ageing serum. The effect varies by formula and skin type.
• Redness and a vulnerable skin barrier: panthenol, centella asiatica, allantoin, ceramides and liquorice root extract are practical ingredients to consider for a sensitive skin serum.

An ingredient listed higher up is usually present in a larger amount than one at the bottom. However, the exact concentration is not always stated. So don’t be guided solely by one prominent ingredient on the front.

2. Check Texture, Fragrance and Skin Compatibility

A thin, watery formula works well under sunscreen or make-up. A richer essence or oily formula may be better suited to dry skin, especially during the winter months. If you react quickly, look for fragrance-free, a short ingredients list and do a patch test.

Fragrance isn’t automatically unsuitable, but it can be a concern for sensitive skin. Likewise, “vegan”, “dermatologically tested” and “alcohol-free” are not universal guarantees of quality. Check exactly what is stated on the product page and packaging.

3. Pay Attention to Volume, Dosage and Time of Use

A 15 ml or 30 ml bottle can be sufficient if you only use a few drops per application. An essence of 50, 100, 150 or 200 ml is often intended as a generous layer after cleansing. A 500 ml pack, such as a lotion, is more suited to daily, generous use.

Use a product according to the instructions. A retinal serum, for example, is intended for the evening and should be introduced gradually. Sunscreen with suitable UV protection is important during the day, especially with products containing retinal, vitamin C or exfoliating ingredients. Stop if you experience clear irritation and consult a doctor or pharmacist if symptoms persist.

Frequently Asked Questions About Face Serums

How do you apply a face serum?

First, cleanse your face and then apply a few drops to the skin. A face essence or essence toner can be used before the serum. Finish with a moisturiser. Use sunscreen during the day, especially if the instructions warn you to do so.

How long does a bottle of serum last?

That depends on the volume and dosage. With two to three drops per use, 30 ml can last several weeks to months. Also look at the symbol for the period after opening and follow the shelf-life information on the packaging. Store the product in a cool, dry place away from direct sunlight when advised to do so.

Can you combine several serums?

Yes, but build up gradually. For example, combine a hydrating serum with a simple moisturiser. Be more cautious with combinations of retinal, acids, vitamin C and azelaic acid serum. Introduce one new product at a time and stop if irritation occurs. This way, you can better discover which formula suits your skin and avoid unnecessary purchases.
