Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate benefits for your normal skin, as niacinamide and glycerin provide excellent humectant action and barrier repair, while diglucosyl gallic acid helps to improve skin tone and texture.
  • The formula also addresses redness and irritation with niacinamide and diglucosyl gallic acid, which soothe and reduce inflammation.
  • The product is safe for your sensitive skin due to the absence of harsh ingredients and the inclusion of soothing components like niacinamide and aloe.

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 .

People Say

This serum is widely praised for its ability to visibly reduce redness, minimize the appearance of pores, and fade post-acne dark spots, making it a favorite for those with oily or acne-prone skin.
