Rudolph Care Serum: The heart of your skincare routine

A serum is one of the most powerful and sensorial steps in your skincare routine. At Rudolph Care, we see serum as the heart of a well-balanced ritual; it's like an undershirt – the first essential layer of care for your skin. A concentrated formula that works deeply to strengthen your skin’s natural balance, hydration, and vitality.

At Rudolph Care, we develop serums with the belief that beauty and care must go hand in hand with consideration for both you and nature. A serum from Rudolph Care is therefore more than an effective skincare product – it’s a moment of wellbeing, where you give your skin exactly what it needs in a pure and uncompromising formula.

Rudolph Care has three serums in the collection. The ultra-hydrating Firming Perfector Serum, rich in hyaluronic acid, which plumps and smooths the skin with moisture and care. Açai All in One Serum, featuring RetinART, evens the skin tone and boosts collagen production – and can help reduce pigmentation with stabilized vitamin C. And finally, Sun Face Serum SPF 30, loved for its light texture and broad-spectrum sun protection combined with hydrating hyaluronic acid and smoothing niacinamide. Sun Face Serum can be used as your daytime serum – throughout the sunny half of the year.

What is a serum – and how does it make a difference for your skin?

A serum is a light, concentrated skincare product that gives your skin a boost of active ingredients. While a cream nourishes and protects the surface of the skin, the serum works deeper – where the skin often needs the most nourishment and care, and where visible results can occur.

A good serum can transform your skincare routine. It strengthens the skin’s moisture balance, improves firmness and elasticity, and gives the skin a radiant glow from within. A serum can bring calm and balance to the skin and help create a more even skin surface.

When you combine serum with your face cream and/or facial oil, you create a synergy where the ingredients work together to give your skin maximum nourishment and care.

Serum for intense hydration, fullness, and glow

If your skin feels dry, has lost some of its fullness, or lacks radiance, a hydrating serum is key to renewed comfort and suppleness. Hyaluronic acid is one of the most effective moisture-binding ingredients – it attracts and retains hydration in the skin, leaving it fresh and alive.

Firming Perfector Serum is an intensely hydrating serum that restores the skin’s moisture balance and gives it fullness. The hyaluronic acid, so to speak, plumps the skin from within. The formula is also rich in active ingredients that strengthen the skin’s resilience and structure – such as apple stem cell extract, which mimics the skin’s own cell signals and activates its natural renewal process. The result is softer, firmer skin that feels stronger and more elastic.

During the summer months, you can replace your serum with Sun Face Serum SPF 30 in your morning routine to give your skin both moisture and smoothing care.

Serum for clear and even skin

If you’re looking for the best serum to give your skin a caring boost and replace dryness lines with radiant skin, Açai All in One Serum is an obvious choice. It’s formulated with the groundbreaking ingredient RetinART, a natural bio-retinol that reduces lines and enhances glow, while stabilized vitamin C evens the skin tone and helps reduce pigmentation. At the same time, açai oil and microalgae deliver antioxidants that protect the skin against free radicals.

When the sun is shining, we always recommend using Sun Face Serum during the day – a true must-have throughout the summer season.

If you have sensitive skin…

Many with sensitive skin can benefit from using Açai All in One Serum, which works with the skin without stressing or disturbing its balance. The natural bio-retinol works like traditional retinol but without the unpleasant side effects such as irritation or the need for SPF in the following days.

If you experience pigmentation spots, the stabilized vitamin C in Açai All in One Serum helps to even your skin tone.

And remember SPF during the sunny months – Sun Face Serum is your best friend!

If you have very sensitive skin or experience conditions such as acne or rosacea, it’s always a good idea to consult a dermatologist to find what works best for your skin.

If you have combination skin…

If your skin tends to be oily or experience impurities, Açai All in One Serum is an excellent choice. The light texture works to even out the skin tone and create a smooth surface without weighing down the skin.

The active ingredient RetinART, a natural bio-retinol, stimulates cell renewal and helps reduce unevenness, while stabilized vitamin C brightens and refines the complexion. At the same time, açai oil and microalgae act as powerful antioxidants that protect and strengthen the skin.

Açai All in One Serum is ideal for combination skin that needs balance, moisture, and lightness – without compromising on care and efficacy.

During the summer season, we always recommend protecting the skin with SPF during the day – so you can easily switch your serum for Sun Face Serum, which also provides hydration.

When and how to apply serum

Apply your serum to clean skin morning and night, before using your face cream and/or facial oil. Use 1–2 pumps and spread the serum gently over the face, neck, and décolleté.

A serum works as an active base that enhances the effect of the products you apply afterward. This means both moisture and nourishment from your cream are absorbed more effectively, giving your skin the most from your routine.

One of our best tips for applying serum is to use a hydrating mist, we recommend Mist Delight, before applying your serum. The hydrating drops act as a transport system for the nourishing ingredients in the serum, helping them absorb deeper into the skin.
