Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers excellent suitability for your oily skin, as azelaic acid and niacinamide work synergistically to control sebum production and reduce pore appearance, directly addressing your concern with oily shine.
  • Snail mucin further supports skin hydration and repair, complementing the primary actives for overall skin health.
  • The formula is safe for your skin, with no identified risks of irritation due to the absence of harsh or prohibited ingredients.

How to apply

  • Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
  • Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
  • Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
  • Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
  • Avoid the delicate eye area and do a patch test before using the serum for the very first time.

People Say

★4.8Overall rating based on 500+ reviews

Users with acne-prone and sensitive skin highly praise this serum for its ability to calm redness and soothe inflammation without causing irritation. While the lightweight, watery texture is frequently complimented for layering well, many users note that fading hyperpigmentation (PIE/PIH) is a gradual process requiring consistent long-term use.
