Key Ingredients

Features & Advantages

Vitamin C Boost
Serum from Ka-rei contains a high concentration of vitamin C derived from citrus fruits. Vitamin C is a potent antioxidant that brightens the skin, fades dark spots, and promotes an even skin tone. It also promotes collagen synthesis, which improves skin elasticity and firmness.

Natural Acids
The serum contains a special combination of natural acids found in citrus fruits, such as citric acid and AHAs (Alpha Hydroxy Acids). These acids exfoliate the skin gently, removing dead skin cells and encouraging cellular renewal. The result is a more refined, smoother complexion with improved texture.

Radiance & Glow
The Citrus Serum’s combination of vitamin C and natural acids works synergistically to boost your skin’s natural radiance. The serum brightens dull skin, revitalizes tired skin, and imparts a healthy, youthful glow.

Antioxidant Defense
Citrus extracts in the serum are high in antioxidants such as flavonoids and limonoids. These antioxidants shield the skin from free radicals, environmental stressors, and premature aging. They also help to keep the skin’s overall health and vitality.

Hydration and Nourishment
Hydrating ingredients in Ka-rei’s Serum help replenish and retain moisture in the skin. This hydration boosts plump and softens the skin, reducing fine lines and leaving it feeling supple and refreshed.

Ka-Rei Serum

Instructions for Use:

  1. Cleanse and pat dry your face thoroughly.
  2. A few drops onto your palm or fingertips.
  3. Cover the entire face with it by massaging in upward circular motions.
  4. Allow the serum to fully absorb into the skin without excessive rubbing.
  5. Use the Serum twice daily, morning and evening, for best results.

Safety Precautions:

  1. Patch before applying the serum to your entire face, test it on a small patch of skin, especially if you have sensitive skin or a history of citrus allergies.

  2. Avoid making direct eye contact. If contact occurs, thoroughly rinse with water.

  3. Because the serum contains natural acids, it may make your skin more sensitive to the sun. During the day, use broad-spectrum sunscreen with an SPF of 30 or higher to protect your skin.
