Lovi Assistant explains

  • Highly suitable for your normal skin, this serum effectively addresses redness and irritation with niacinamide and tranexamic acid, which reduce inflammation and improve skin tone.
  • The inclusion of kojic acid further aids in evening skin tone, complementing the primary ingredients for enhanced brightening.
  • The product is safe for your sensitive skin, as it contains no harsh or prohibited ingredients that could cause irritation.

How to apply

  • Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
  • Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
  • Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
  • Always do a patch test before your first use and avoid getting the serum too close to your eyes .
