Your guide to serum: What is serum, and which serum should I choose?
Throughout your life, your skin changes - due to natural ageing, hormonal fluctuations, pollution and the sun.
A serum is both your skin’s weapon for prevention - and its repairer for rebuilding.
Here you can read all about the abilities and properties of serum, and get guidance on which serum best boosts your skin’s health and glow.
What is a serum?
A serum is a skincare product that works deeply to boost the skin and stimulate its regeneration. Serum is a concentrate of active ingredients that work specifically to treat a particular concern, skin condition or skin problem - going all-in to address it.
Serum has a light consistency that allows the ingredients to penetrate the upper layers of the skin. Here, the active ingredients work effectively and in a concentrated way to improve and support the skin’s natural functions.
A serum can help your skin do everything from regaining its elasticity and smoothing its surface to boosting its vitamin and moisture levels.

Why should I use serum?
Serum is an important step in your skincare routine because it improves your skin, strengthens its resilience and enhances the effect of your other products.
While a face cream is designed to moisturise and care for your skin more broadly, serum provides a power boost precisely where your skin has concerns - whether that’s redness, acne, fine lines or dryness.
Your serum will contain active ingredients, such as salicylic acid for acne, hyaluronic acid to create elasticity and vitamin C for pigmentation changes.
Serum does more than bring your skin back into balance - it also supports the skin so that it becomes healthier and stronger than before.
Which serum should I choose?
Choose the serum that is developed to target your skin concern. If you struggle with dry skin, your serum should provide a moisture boost, and if you’re tired of lines and wrinkles, choose a serum with firming properties.
Many of us can experience several skin concerns at once. In that case, you can easily use two different serums, for example a moisturising serum in the morning and a firming serum on fine lines in the evening.
At ECOOKING, our family of serums is developed to help your skin type with its specific needs for care and strength. Let the overview here guide you.

How and when should I use a serum?

Use your serum after you have cleansed your skin and before applying your face oil and day or night cream. Apply your serum all over your face and, ideally, down your neck and chest too.
Serum has a light, fluid consistency, and when you apply cream over your serum, the cream acts as a protective layer that allows the serum to penetrate and work undisturbed.
You can use a Derma Roller to gently apply your serum. The Derma Roller contains microneedles that stimulate skin cell renewal and allow the serum to reach your pores.
When using serum with active ingredients such as vitamin A or vitamin C, it is important to always protect your skin with sunscreen during the day.
WORTH KNOWING: It is important to choose a serum that is not too harsh for your skin. If you have young skin, primarily look for a moisturising and soothing serum and wait before using high concentrations such as Retinol and Argireline, which are best suited to mature skin.
4 selected benefits of face serum
- Serum has a thin and light consistency, allowing the ingredients to be quickly absorbed into the upper layers of the skin. Serums are easy to apply as part of your facial care routine and do not leave your skin greasy under your makeup.
- Many people find that their serum provides visible improvements over time because the effective ingredients work actively and specifically in the skin. This improves and strengthens the skin where it needs it most.
- You can change your serum over time as your skin changes. For example, use Moisture Serum as a regular part of your daily routine, Acne Serum during periods of hormonal fluctuations and Pigmentation Serum when you want to reduce pigmentation spots.
- Besides addressing specific skin concerns, serums also protect against external influences such as UV radiation and pollution. Antioxidants such as vitamin C and vitamin E protect your skin and improve its overall health.
