Shiseido HAKU Melanofocus IV is a powerful brightening serum that suppresses excessive melanin production and prevents the formation of dark spots and freckles. Two active formulas (4MSK and m‑tranexamic acid) act at the root of the problem, providing prevention and protection. The additional action of dipotassium glycyrrhizate soothes and prevents inflammation, keeping skin even and healthy.

Active ingredients and their effects:

4MSK (potassium 4‑methoxysalicylate) is the key brightening ingredient that suppresses melanin production in the epidermis, preventing spots and freckles while maintaining skin translucency and radiance.
m‑tranexamic acid works together with 4MSK to block inflammatory and pigmentary processes that provoke persistent spots, providing long‑term pigmentation prevention.
Dipotassium glycyrrhizate is a natural anti‑inflammatory ingredient that reduces irritation, soothes the skin, and prevents roughness and flaking.
Vitamin C in a stable form (3‑O‑ethyl ascorbic acid) is a powerful antioxidant that protects cells from damage, boosts collagen production, and gives the skin a healthy glow.
Hyaluronic acid deeply hydrates by binding moisture in tissues, making skin soft and elastic, eliminating tightness and supporting water balance throughout the day.
Plant extracts provide soothing and antioxidant effects, support natural renewal processes, and help strengthen the skin’s protective barrier.

HAKU Melanofocus IV serum effectively fights visible imperfections. With regular use, skin appears healthy, hydrated, and radiant.
