SISÓNE takes a longevity-inspired approach to skincare, with a focus on long-term skin vitality rather than short-term beauty trends. Our philosophy brings together modern skincare science, thoughtful formulation and a Scandinavian perspective on simplicity, balance and quality.

We create skincare with the long run in mind — designed to become a considered part of your everyday routine and to support the skin through every stage of life.

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a naturally occurring molecule found in every living cell. It plays a central role in cellular energy metabolism, helping cells convert nutrients into usable energy.

NAD⁺ is also involved in important cellular processes related to signaling, stress response and DNA repair, including processes involving sirtuins and PARP enzymes. These functions have made NAD⁺ an important area of interest within longevity research and the study of how cells maintain normal function over time.

NMN (Nicotinamide Mononucleotide) is a naturally occurring molecule and a direct precursor to NAD⁺, meaning that cells can use NMN as part of the process of producing NAD⁺.

Because NAD⁺ plays an essential role in cellular energy metabolism and other cellular processes, NMN has become an important area of interest within longevity research. Scientists continue to study the relationship between NMN, NAD⁺ metabolism and cellular function during ageing.

Our formulations are built around carefully selected ingredients, including NAD⁺, NMN, Hyaluronic Acid and 24K Gold. NAD⁺ and NMN are connected to cellular energy metabolism and are widely studied within longevity research, while Hyaluronic Acid helps attract and retain moisture in the skin. 24K Gold complements the formulas, reflecting our approach to combining advanced ingredients with a refined skincare experience.

Use each product according to its individual directions and apply your skincare from lighter to richer textures. Begin with clean, dry skin and allow each product to absorb before applying the next step. Some products are designed specifically for morning or evening use, so follow the recommended AM or PM routine for each formula. Consistent use as part of your daily skincare routine will help you get the most from each product.

Our formulas are developed with carefully selected ingredients and are designed to suit a variety of skin types. As every skin is different, we recommend reviewing the ingredient list and performing a patch test before use, especially if you have sensitive or reactive skin. If irritation occurs, discontinue use.
