I often get questions about whether using a face serum is necessary. So, I decided to dispel any doubts and explain the role of serums in skincare and how to use them. A face serum is a cosmetic with a highly concentrated formula, containing high concentrations of active ingredients such as vitamins, peptides, and acids. Thanks to its light consistency and deep penetration, a serum can significantly improve the skin's condition—moisturizing, brightening, firming, or helping to combat imperfections. However, for a serum to be as effective as possible, proper use is crucial. In this article, you'll find a practical step-by-step guide that will show you how and when to apply a serum, how to choose one for your skin type, and what to pay attention to in your daily skincare routine.

Why is using serum important?
It is worth using serum because:
- works faster and more intensively than cream,
- goes deeper into the layers of the epidermis,
- can significantly improve skin condition after just a few weeks,
- complements the action of other cosmetics in the care routine.
How to properly use facial serum?
When to apply the serum - morning or evening?
It depends on the type of serum and its composition.
- In the morning, antioxidant serums, such as those with vitamin C, niacinamide, trehalose or ectoine, are best because they help protect the skin against external factors.
- In the evening, it is worth reaching for a regenerating serum with acids (e.g. PHA, AHA, BHA), retinoids, peptides or ceramides, which support night-time cell renewal.
How often should you use a facial serum?
Most serums can be used daily – morning and/or evening , with the exception of intensely exfoliating products, which should be applied 2–3 times a week. For sensitive or inflamed skin, it's best to start with a lower frequency and observe your skin's reaction.
How to apply serum - step by step?
- Makeup removal and cleansing – thoroughly remove makeup and impurities.
- Toning – restore the proper skin pH with tonic or hydrolate.
- Serum application – Apply 2–4 drops of serum to dry or damp skin on the face, neck, and décolleté. Spread gently without rubbing.
- Wait a while (30–60 seconds) for the product to absorb.
- Apply cream – protect the serum with a layer of cream, which will prevent the active ingredients from evaporating and enhance their effect.
The order of applying cosmetics with serum - are you doing it right?
The rule is simple: from the lightest to the heaviest consistency .
A typical routine looks like this:
- Cleaning
- Tonic/essence
- Serum
- Cream
- Sunscreen (morning)
Important: Serums do not replace cream . Even if they seem "rich," they do not have an occlusive effect—so they should always be covered with cream.
How to choose a serum for your skin type?
The choice of serum should be based on your skin's needs and type. Examples:
Skin type – Recommended active ingredients:
- Dry: hyaluronic acid, trehalose, ceramides, tremella
- Mixed: niacinamide, zinc, green tea, PHA (gluconolactone, lactobionic acid)
- Oily/acne: salicylic acid, BHA, retinol, neem, bakuchiol, tremella
- Mature: retinol, peptides, coenzyme Q10, reihi, trehalose
- Vascular: vitamin C (stable), niacinamide
- Sensitive: ectoine, centella asiatica, panthenol, lactobionic acid
Frequently asked questions about using facial serums (FAQ)
Can the serum be used under the eyes?
Not all serums are suitable for this purpose. It's worth choosing products specifically designed for the eye area, with a balanced pH and ophthalmologically tested.
How long should I wait before applying the cream?
Usually, 30–60 seconds is enough – this is how long it takes for the serum to absorb and not roll under the cream.
Can you combine different cheeses?
Yes, but with caution. Combining vitamin C with niacinamide or peptides with hyaluronic acid is safe, but some ingredients (e.g., retinol and AHAs) may irritate the skin when used together.
Summary – how to best use the potential of a facial serum?
Using a serum is one of the most effective ways to consciously and effectively care for your skin. The key to success, however, lies not only in choosing the right product but also in applying it correctly, consistently, and adapting it to your skin's needs. If you incorporate a serum into your routine according to the tips above, you'll notice improvements in skin hydration, firmness, and overall appearance over time.
