EPISODE 01
1:47Why BOOST-UP works so well after cosmetic treatments
Why BOOST-UP is recommended after cosmetic treatments and how to use it during the first seven to ten days.
Transcript & sources
Lea: Sarah, BOOST-UP is particularly recommended after cosmetic treatments. Why is this serum so well suited to that phase?
Sarah: Because that is exactly what we developed it for: it is lightweight, oil-free and fragrance-free, yet provides intensive care. BOOST-UP hydrates the skin, helps it feel pleasantly soothed and provides cosmetic support for the skin’s natural renewal process, without feeling heavy.
Lea: And what does the recommendation mean for the first seven to ten days?
Sarah: During this period, we recommend using BOOST-UP morning and evening as your sole intensive skincare product. Apply one or two pumps to cleansed skin, gently spread it over the face, neck and décolletage, and pat it in. This keeps the routine clear and focused.
Lea: What makes the formulation particularly suitable for this?
Sarah: It is the way the ingredients work together: our five-fold Growth Factor Peptide System, 4D hyaluronic acid for multi-layer hydration, niacinamide, soluble collagen, aloe vera and natural moisturising factors. We do not expect one fashionable ingredient to do everything. The entire formula works as a coordinated skincare concept.
Lea: And after the intensive phase?
Sarah: BOOST-UP simply becomes part of your daily routine: use it morning and evening before your usual skincare products. If your skin is dry, follow with a richer cream. Alternatively, mix one pump with your favourite cream in the palm of your hand.
Lea: What is the most important thing to remember after a cosmetic treatment?
Sarah: Good cosmetic skincare does not stop at the treatment-room door. BOOST-UP helps you continue that care consistently at home: lightweight, intensive and uncomplicated.

EPISODE 02
1:57How to make BOOST-UP part of your daily routine
A simple morning and evening routine with BOOST-UP, including layering, mixing and sun protection.
Transcript & sources
Lea: Sarah, many people buy a serum and only ask themselves once they are home: where does this fit into my routine? Let’s make it very practical today.
Sarah: Of course. Apply BOOST-UP to the face, neck and décolletage after cleansing, morning and evening. One or two pumps are enough. Gently pat it in, allow it to absorb briefly and then apply your usual skincare products.
Lea: What does that look like in the morning?
Sarah: Cleanse, apply BOOST-UP, follow with your daytime moisturiser and finish with sun protection. The serum is oil-free and absorbs easily, so it sits very well under both a daytime cream and SPF.
Lea: And what if my skin needs more nourishment?
Sarah: There are two easy options. You can apply a richer cream after BOOST-UP, or mix one pump with your favourite cream in the palm of your hand. Both methods are explicitly included in the intended use.
Lea: Do I have to replace my entire existing routine?
Sarah: No. BOOST-UP is designed to enhance an existing routine. It combines intensive hydration, the five-fold Growth Factor Peptide System, 4D hyaluronic acid, niacinamide and other conditioning components in a single, everyday step.
Lea: Is there a difference between regular use and the period after a cosmetic treatment?
Sarah: Yes. As part of your everyday routine, use BOOST-UP before your usual skincare products or mix it with them. After cosmetic treatments, we recommend it as your sole intensive skincare product for the first seven to ten days. After that, it can simply return to its usual place in your morning and evening routine.
Lea: What is the short version to remember?
Sarah: One or two pumps, morning and evening. Used on its own, under your skincare products or mixed with your favourite cream, BOOST-UP adapts to your routine.

EPISODE 03
2:24What really makes BOOST-UP premium
BOOST-UP’s premium quality comes from a clear purpose, a coordinated formulation and a routine that works in everyday life.
Transcript & sources
Lea: Sarah, premium skincare is often discussed in terms of individual active ingredients. In your view, what truly makes BOOST-UP a premium product?
Sarah: Three things: its clear purpose, its coordinated formulation and how it works in everyday use. BOOST-UP is designed to provide intensive hydration, support a smoother, fresher-looking complexion and still feel lightweight and pleasant on the skin.
Lea: And what makes that more than just an appealing description?
Sarah: The way the ingredients work together. The five-fold Growth Factor Peptide System does not stand alone. It is joined by 4D hyaluronic acid, soluble collagen, niacinamide, aloe vera, amino acids and components of the skin’s natural moisturising factor. The formula is oil-free, fragrance-free and pH-optimised.
Lea: So this is not ingredient bingo?
Sarah: Exactly. We did not simply collect as many familiar names as possible. Every component has a place within the overall concept. Humectants help retain water in the upper layers of the skin. Niacinamide supports the skin barrier. Signal peptides form part of the product’s cosmetic care and communication concept. The base allows the serum to spread easily without weighing down the skin.
Lea: What does the person standing in front of the bathroom mirror notice?
Sarah: That one or two pumps are enough, that the serum quickly becomes part of their routine and that it combines easily with the skincare products they already use. Premium quality is not only visible in an ingredient list. It is also reflected in how coherent a product feels, from the first pump to regular use.
Lea: And what about skin tolerance?
Sarah: BOOST-UP was independently dermatologically tested on sensitive skin and rated ‘VERY GOOD’. For us, that is another important part of a premium formulation.
Lea: Your conclusion?
Sarah: With BOOST-UP, premium is not a single buzzword. It is the sum of the formulation, the way it feels on the skin, how well it is tolerated and a method of use that people can genuinely maintain.

EPISODE 04
1:574D hyaluronic acid, simply explained
What 4D hyaluronic acid means and why different forms of hyaluronic acid are combined for multi-layer hydration.
Transcript & sources
Lea: Sarah, 4D hyaluronic acid sounds technical at first. In simple terms, what does it mean in BOOST-UP?
Sarah: It means that we do not use just one form of hyaluronic acid. Different forms, or molecular sizes, complement one another to bind moisture at several levels within the upper layers of the skin. That is why we call it multi-layer hydration.
Lea: Why is that more interesting than simply saying ‘with hyaluronic acid’?
Sarah: Because not all hyaluronic acid is the same. Larger molecular structures tend to remain on the surface, where they support a smooth, pleasantly hydrated skin feel. Smaller structures can be distributed differently within the stratum corneum. Together, they create a graduated hydration concept.
Lea: Does that make up BOOST-UP’s entire hydration complex?
Sarah: No, and that is important. The 4D hyaluronic acid does not work alone. Aloe vera, urea, sodium lactate and sodium PCA complement the skin’s hydration. Soluble collagen also supports a moisture-binding film on the skin’s surface.
Lea: That is much easier to understand than reading out a long INCI list.
Sarah: That is exactly the aim. Anyone who wants to explore the details can, of course, consult the complete ingredient list. For everyday use, this idea is enough: BOOST-UP combines different approaches to hydration in a lightweight, oil-free formula.
Lea: When do you notice the difference most?
Sarah: When the skin is craving moisture, feels tired or stressed, or needs concentrated yet lightweight care after a cosmetic treatment. For everyday use, one or two pumps morning and evening are enough.
Lea: The one sentence to take away?
Sarah: In BOOST-UP, 4D hyaluronic acid is not about making more noise. It is about multi-layer hydration through intelligently combined forms of hyaluronic acid.

1:46DOUBLE: Two phases for face, body and scalp
Why DOUBLE visibly separates, why shaking is essential and how versatile the fluid is in everyday use.
Transcript & sources
Lea: Sarah, DOUBLE looks different from a conventional serum in the bottle. Why does it visibly separate?
Sarah: Because the two phases are intentional. The water phase carries water-soluble conditioning ingredients. The lightweight lipid phase delivers oil-soluble active ingredients and nourishing lipids. Before use, shake the bottle vigorously until a milky emulsion forms.
Lea: What is the benefit of that?
Sarah: DOUBLE combines intensive hydration with lipid care without feeling like a heavy cream. That makes it particularly versatile for stressed, rough or flaky areas of skin.
Lea: Where can I apply it?
Sarah: On the face, body and scalp. Apply a few drops to the desired areas in the morning or evening and massage the product in gently. Typical areas include dry shins, elbows and knees. On the scalp, it can be applied section by section and left on overnight, for example. It is also intended for the skin beneath the beard or for use after shaving.
Lea: And what do the two phases contain?
Sarah: Together, the two phases contain a five-fold peptide complex, resveratrol, calendula, betulin, niacinamide, hyaluronic acid, natural moisturising factors and lightweight lipids. Once again, what matters is how everything works together: soothing care, hydration, lipids and antioxidant components in a two-phase system.
Lea: Can DOUBLE be combined with other skincare products?
Sarah: Yes. You can apply it before your usual skincare products or mix a few drops into a cream or body lotion as a booster.
Lea: What is the most important application tip?
Sarah: Shake vigorously first, then apply it where your skin needs care. The visible separation is not a fault; it is the principle behind DOUBLE.

2:04BOOST-UP and DOUBLE together: light in the morning, intensive at night
Sarah presents a simple combined routine with BOOST-UP in the morning and DOUBLE as an evening skincare step.
Transcript & sources
Lea: Sarah, can BOOST-UP and DOUBLE be used in the same routine?
Sarah: Yes, absolutely. The two products combine very well. They can take on different roles or complement one another, depending on what your skin needs.
Lea: Give us a very simple example.
Sarah: In the morning, apply one or two pumps of BOOST-UP to the face, neck and décolletage after cleansing. Follow with your daytime moisturiser and sun protection. In the evening, cleanse your skin, shake DOUBLE vigorously and apply a few drops as a richer skincare step.
Lea: Why does this division work so well?
Sarah: BOOST-UP is oil-free, lightweight and focused on intensive hydration. It sits comfortably under a daytime moisturiser and SPF. DOUBLE combines a water phase with a lipid phase. This makes it particularly well suited to evening use, when the skin needs additional nourishing lipids and a richer skin feel.
Lea: Can I use DOUBLE only on selected areas in the evening?
Sarah: Of course. The routine is flexible. You can use DOUBLE on the face or apply it specifically to dry or stressed areas. It is also explicitly intended for use on the body and scalp.
Lea: And what if I would rather layer both products in the same routine?
Sarah: That is possible too. Apply BOOST-UP first and allow it to absorb briefly. Then follow with DOUBLE, after shaking it thoroughly, or with your usual skincare product. Both products can be combined with other skincare products.
Lea: So there is no reason to set them against each other artificially?
Sarah: Exactly. BOOST-UP and DOUBLE are not an either-or choice. They are two formulation concepts that work individually and together create a very coherent morning and evening routine.
Lea: What is the short version to remember?
Sarah: BOOST-UP under your daytime moisturiser and SPF in the morning, DOUBLE as an intensive skincare step in the evening: simple, easy to combine and practical for everyday life.

2:04A routine that fits your life
It is not the number of products that matters, but a routine with clear steps that work well together.
Transcript & sources
Lea: Sarah, does a good skincare routine have to be as short as possible?
Sarah: No. Short is not automatically good, and long is not automatically wrong. What matters is whether you understand the purpose of each step and whether the routine fits your everyday life.
Lea: How can I assess that in my own skincare routine?
Sarah: Ask yourself three questions about each product: What should it do for my skin? When should I use it? And what can I combine it with? If you can answer those questions, your routine becomes easy to understand.
Lea: What does that mean for BOOST-UP?
Sarah: BOOST-UP is the lightweight, oil-free serum step for intensive hydration, a fresher-looking complexion and cosmetic support for the skin’s renewal process. Use one or two pumps morning and evening, followed by your usual skincare products. After cosmetic treatments, it can be used as the sole intensive skincare product for seven to ten days.
Lea: And DOUBLE?
Sarah: DOUBLE is the shake-to-activate, two-phase fluid for the face, body and scalp. It combines hydration with lipid care and can be applied over a larger area or specifically to stressed patches of skin.
Lea: How does that become a personal routine?
Sarah: For example, use BOOST-UP, a daytime moisturiser and SPF in the morning, then DOUBLE as your evening skincare product. Or use BOOST-UP in the morning and evening, adding DOUBLE only to dry areas, the scalp or skin after shaving. You can also combine both products with creams you already know and trust.
Lea: So it is not about using as little as possible?
Sarah: Exactly. It is about combining products consciously. A good routine does not feel like a test. It gives you clarity and is easy enough to repeat consistently, so skincare truly becomes part of your everyday life.
Lea: Your final thought for this season?
Sarah: Understand the purpose, choose the right formulation and combine products in a way that suits your skin and your everyday life.
