Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers high suitability for oily skin due to the presence of Ascorbic Acid with antioxidant activity and Lactic Acid with keratolytic action, which help to refine texture and provide antioxidant protection.
  • While the product offers general skincare benefits like hydration and cleansing, it lacks targeted ingredients such as salicylic acid or niacinamide to effectively address your primary concerns of acne, blemishes, and breakouts.
  • The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of prohibited or harsh ingredients.

How to apply

  • Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
  • Apply your serum after cleansing and toning, but before putting on your moisturizer.
  • Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
  • Apply the serum on clean, dry skin to help manage your blemishes safely.
  • Do a patch test before your first use and avoid the delicate eye area.
