• Pigmentation control: the serum contains kojic acid, an active lightening ingredient that inhibits the formation of melanin in the skin. This helps reduce the intensity of existing dark spots and prevent the appearance of new ones (age spots, post-acne marks, freckles).
  

• Evens out skin tone: The formula targets melanocytes, the cells that produce pigment, to gradually reveal brighter, clearer, and less dull skin.
  

• Prevention of “future” spots: the serum works not only with what is already visible, but also with hidden pigmentation that is formed under the influence of UV and micro-inflammation. Regular use helps reduce the risk of these spots appearing on the surface.
  

• Hydration and softness: The formula base contains humectants, emollients and antioxidants. This keeps the skin hydrated without feeling tight after application.

• Kojic Acid: inhibits tyrosinase, an enzyme that triggers melanin synthesis; helps reduce already visible age spots and prevent the appearance of new ones.
  
•  Sodium Acetylated Hyaluronate: retains moisture on the skin's surface for long-lasting hydration and softness.
  
•  Zanthoxylum bungeanum Extract: maintains an even tone and helps limit the “spread” of pigmentation.
  
•  Phellinus Linteus Extract: a plant-fungal extract with soothing and antioxidant effects, helps reduce dullness.
  
•  Tocopherol: an antioxidant that supports skin protection against oxidative stress and affects the overall appearance of the skin (smoothness, elasticity).
  
•  Trans-Resveratrol: an antioxidant that further supports “transparency” and even tone.

ONE BY KOSÉ Melanoshot W is a kojic acid-based facial serum that targets pigmentation. It is designed for people who have dark spots (sun, age, acne) or uneven skin tone, and for those who want to prevent new spots from appearing.

The main ingredient is kojic acid. This is an officially recognized lightening ingredient in Japan that reduces melanin production in the skin. This means that the serum doesn’t just mask dullness, but works on the cause of the darkening.

Additionally, the formula contains moisturizing ingredients (modified hyaluronic acid, glycerin), antioxidants (vitamin E, resveratrol) and plant extracts. This helps keep the skin soft and comfortable, without feeling tight.

The texture is light, quickly absorbed, non-sticky. Suitable for daily use in the morning and evening.
