The High Intense Serum was developed for skin that can already do more – and wants more.A highly active, biomimetic active ingredient formula combines multi-molecular hyaluronic acid, peptides, niacinamide, ectoine, and a vitamin complex to strengthen, hydrate, and visibly smooth the skin layer by layer. The texture is light, absorbs immediately, and leaves nothing but noticeably softer, plumper skin from day one.

Intensive Hydration & Plumping: Three forms of hyaluronic acid deliver moisture to different depths of the skin and visibly improve skin elasticity. Barrier Strengthening & Cell Protection: Ectoin, Niacinamide, and Panthenol soothe, protect, and promote resilient, balanced skin. Structure & Regeneration: Peptides, Vitamin C, Vitamin E, and Retinyl Palmitate support cell renewal, smooth fine lines, and refine skin texture – without irritating active ingredient peaks. Balancing Vitamin Complex: B vitamins (B2, B3, B5, B6, folic acid) support natural skin function and promote a healthy, even complexion.

The serum is ideal for skin types that can already tolerate higher concentrations of active ingredients, e.g.: skin that already regularly uses serums and is looking for "more effect"; fine lines, first signs of structural loss, tired or dull skin; dehydrated, sensitive, or easily irritated skin that nevertheless tolerates stronger active ingredients. Customers who are looking for a powerful serum without irritants.

Aqua (Water) – Base of the formulation, delivers active ingredients deep into the skin.Pentylene Glycol – moisturizing, supports the absorption of active ingredients.Sodium Hyaluronate – high molecular weight hyaluronic acid for immediate hydration and plumping effect.Hydrolyzed Hyaluronic Acid – low molecular weight hyaluronic acid, penetrates deeper and improves elasticity.Sodium Hyaluronate Crosspolymer-3 – cross-linked hyaluronic acid for long-lasting moisture depots.Ectoin – strong cell-protective ingredient, soothes, protects, and strengthens the skin barrier.Glycerin – natural humectant, keeps the skin soft and supple.Panthenol (Provitamin B5) – soothes, regenerates, and supports a strong skin barrier.Riboflavin (Vitamin B2) – antioxidant, promotes an even complexion.Niacinamide (Vitamin B3) – reduces redness, refines the skin's appearance, and strengthens the skin structure.Pyridoxine (Vitamin B6) – supports skin metabolism and has a balancing effect.Lecithin – skin-identical component, stabilizes the formulation, and improves tolerability.Folic Acid – supports cell regeneration and skin renewal.Tocopheryl Acetate (Vitamin E) – protects against free radicals and promotes a smoother skin feel.Ethyl Ascorbic Acid (stable Vitamin C) – gently brightens, protects against oxidation, supports collagen structure.Retinyl Palmitate (Vitamin A compound) – gentle cell renewal, improves skin texture and evenness.Benzyl Alcohol – mild component of the preservative system, necessary for product safety.Benzoic Acid – ensures microbiological stability, skin-friendly preservative.Dehydroacetic Acid – supports gentle preservation, protects the formula from spoilage.Full list: Aqua (Water), Pentylene Glycol, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer-3, Ectoin, Glycerin, Panthenol, Riboflavin, Niacinamide, Pyridoxine, Lecithin, Folic Acid, Tocopheryl Acetate, Ethyl Ascorbic Acid, Retinyl Palmitate, Benzyl Alcohol, Benzoic Acid, Dehydroacetic Acid.

Cell Resistance & Anti-Pollution

Protection against premature aging caused by environmental stress.
An invisible shield for your skin cells.
Every day, your skin is exposed to stressors such as UV light, fine dust, and dry heated air. This high-end treatment forms a stabilizing protective layer around your cells. It massively increases the resilience of the skin barrier and ensures that moisture stays where it belongs, even under extreme conditions. For a skin feeling that remains relaxed and protected all day long.

Ectoin Stress Protection:

This active ingredient forms a natural protective shield around skin cells, protecting them from extreme environmental influences and preventing moisture loss at a cellular level.

  • Immediate barrier relief:

    Noticeable reduction of feelings of tightness and redness directly after the first application.

  • Structural Padding:

    Dehydration lines are "erased" from within by the 5x hyaluronic complex.

  • Long-term resistance:

    Your skin becomes more resistant to external stressors thanks to Ectoin and ceramides.

Founder Patrizia:

"The High Intense Serum was RE SKIN's first serum in 2018 – and it was way ahead of its time. While active ingredients like ectoine, niacinamide, or folic acid are on everyone's lips today, they were already standard for us back then.
From the beginning, my goal was to create a master serum that combines medical-grade efficacy with absolute tolerability. Even after years, this formulation remains the undisputed gold standard in my routine. It is the perfect product for anyone who doesn't want to compromise: a highly concentrated all-rounder that not only nourishes the skin but also protects and regenerates it at a cellular level."

  • Free from silicones & mineral oils:

    We rely on lecithin to deliver 3% hyaluronic acid and vitamins deep into the skin without clogging pores.

  • 100% Fragrance-Free:

    Despite the complex vitamin formula, we consistently forgo fragrances to guarantee maximum tolerability.

  • Microplastic & dye-free:

    The silky consistency is a direct result of our active ingredient density

  • Vegan & Clean

    Respectful of animals and skin – Made in Germany.

  • Ectoine (Cell Protection Molecule):

    A natural high-tech active ingredient that protects your cells like a shield from environmental stress, heat and dehydration, and inhibits inflammation.
    Stabilized Vitamin C (Ethyl Ascorbic Acid): A particularly gentle and light-stable form. It protects against free radicals, promotes collagen formation, and ensures a bright, even glow.

  • Multivitamin Complex (A, E & B-series):

    Multivitamin Complex (A & B Series): This cocktail acts as an energy system where Retinyl Palmitate (A), Niacinamide (B3), and Folic Acid work hand in hand to activate cell renewal and refine pores.

  • Stabilized Vitamin C (Ethyl Ascorbic Acid):

    A particularly low-irritation and light-stable form. It protects against free radicals, promotes collagen formation, and provides a bright, even glow.

  • Vitamin E: Boosts antioxidant protection.

    The classic protective active ingredient. It smooths the skin's surface, improves moisture retention, and protects the valuable lipids of your skin barrier from oxidation.

  • The Texture: 3% Pure Potency - Noticeable Intensity.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.
