Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Suitable for normal skin, this serum utilizes niacinamide and glycerin to provide antioxidant, anti-inflammatory, and humectant actions, which are beneficial for general skin health and hydration.
  • While it offers good pore-cleansing and texture improvement, it lacks specialized ingredients to directly target your redness and irritation.
  • The formulation is safe for your sensitive skin, as it avoids 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 .

People Say

★4.6Overall rating based on 3.4k+ reviews

Based on a very large amount of data, this serum is highly regarded for its lightweight, non-sticky feel and its effectiveness in visibly reducing pores and smoothing skin texture, all at an accessible price. Many users found it beneficial for controlling oil and redness.
