Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening for your pigmentation concerns, as Ascorbic Acid and Ascorbyl Glucoside provide antioxidant and evening effects suitable for normal skin.
  • The presence of Sodium Hyaluronate offers some hydration, though a more robust humectant profile could further enhance skin comfort.
  • The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

How to apply

  • Apply this serum as part of your PM routine starting 3x/week and build up to daily use if your skin likes it.
  • Place the serum after cleansing and toning, but before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and wait a minute for it to absorb.
  • Apply the serum on dry skin to help fade pigmentation effectively.
  • Avoid the eye area and always use SPF 30+ during the day.
