Choosing the right face serum: our tips

Finding the right serum can seem complex. Skin changes, and so do its needs: radiance, hydration, anti-aging, soothing, spot correction…
This guide helps you understand each formula for choosing the A serum that's truly suited to your face.

Understanding what a serum is

A serum is a concentrated treatment that targets a specific problem: hydration, wrinkles, spots, redness, imperfections, loss of firmness…
Its fine texture allows powerful active ingredients (hyaluronic acid, vitamin C, niacinamide, botanical extracts…) to penetrate more quickly and act in depth , whereas a cream only moisturizes the surface.

• Its formula contains a high concentration of active ingredients .
• It acts as a reinforcement , a booster that improves the results of the routine.
• It is used before the cream, morning and evening.
• It is suitable for all skin types, even sensitive skin.

To go far...

When should you use your serum?

The serum should be used morning and evening , on clean skin, immediately after cleansing. This regularity helps the active ingredients work deeply and maintain optimal hydration.

Here are the best moments:

• The morning
  It prepares the skin for makeup, strengthens protection against external aggressions (pollution, temperature variations, oxidative stress) and provides an immediate glow.
  → A vitamin C or moisturizing serum works particularly well at this time.
• The evening
  The skin enters a phase of cell renewal : this is the ideal time for anti-aging, anti-blemish, soothing or purifying formulas.
  → The serum slips perfectly under a night cream to increase the effectiveness of the ritual.
• After exfoliation
  The Magic Pschitt can be used every day (unique case among exfoliants of this type).
  It smooths the skin surface and allows the serum to penetrate with even greater precision.

A helpful tip: a serum works best when applied right after gentle cleansing — the skin then absorbs the treatment easily, without overloading.

Why use a serum?

Serum has become essential because it provides what neither a cream nor a mask can offer: targeted, deep, and immediate action . Its fine texture infuses the skin with powerful active ingredients capable of transforming its appearance day after day.

Here's what a serum actually provides:

• A precise response to the skin's needs
  Hydration, radiance, anti-aging, anti-blemish, soothing, purification… Each formula concentrates active ingredients chosen for a well-defined problem.
  → Example: hyaluronic acid to plump, niacinamide to soothe, vitamin C to illuminate, salicylic acid to reduce imperfections.
• Deeper penetration
  Thanks to its fluid texture, the serum reaches skin levels where the cream does not act.
  The active ingredients act on collagen, cell renewal, sebum regulation, and pigmentation.
• A boosting effect for your routine
  The cream then seals in the moisture, but the serum prepares the ground.
  The result: a more effective routine, a more even complexion and skin that reacts better to skincare.
• A visible improvement in the appearance of the skin
  Dull complexion, visible pores, wrinkles, spots… The serum works on the details that change everything.
  Several weeks are enough to observe a clear and gradual change.
• A gesture suitable for all skin types
  Even sensitive, oily, mature or acne-prone skin can find a suitable serum.
  Each skin type benefits from a specific action without overloading.

The serum then becomes a daily companion capable of providing the precision, gentleness and effectiveness that one expects from a modern skincare product.

How to apply it?

Applying the serum makes all the difference. A few simple steps are all it takes to increase its effectiveness and allow the active ingredients to work in close proximity to the skin's needs.

Here is the most effective method:

1. Prepare the skin

Gentle cleansing helps to remove sebum, impurities and traces of makeup.
The skin should be clean, slightly damp if possible — water facilitates the penetration of active ingredients.

2. Exfoliate if necessary

The Magic Pschitt can be used every day , a rare feature among exfoliants.
It smooths the surface, unclogs pores and optimizes serum absorption.
Other classic exfoliants, on the other hand, are used 1 to 2 times a week .

3. Warm the serum between your hands

A few seconds are enough to make the texture more fluid and allow for even application.

4. Place a few drops

Apply a small amount to:

• the front,
• the cheeks,
• the nose,
• the chin,
• then go down to the neck.

"A small amount of product, but well placed" is often the most effective rule.

5. Smooth gently

From the center of the face outwards, with upward movements.
The serum's fine texture glides on effortlessly and absorbs quickly.

6. Emphasize the targeted areas

Spots, visible pores, fine lines, dry patches or imperfections…
The serum works precisely when you take the time to massage these points.

7. Finish with a suitable cream

The cream seals in moisture and prolongs the action of the serum.
→ A day cream in the morning,
→ A richer or soothing cream in the evening.

Trick : Lightly tap the eye contour area if the serum is suitable for this area; this enhances the smoothing and decongesting effect.
