Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate benefits for your combination skin, as ascorbic acid, tocopherol vitamin e, and ferulic acid provide antioxidant protection and support collagen synthesis, which can be helpful for oily shine.
  • While generally beneficial, the formula does not specifically target oily shine, and lighter humectant support could further enhance comfort for combination skin.
  • The product is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

How to apply

  • Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
  • Apply the serum after cleansing and toner, and right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
  • Apply the serum on clean and dry skin since your skin is not sensitive.
  • Always do a patch test before using the serum for the first time, and avoid the eye area .

People Say

★4.6Overall rating based on 1000+ reviews

Based on a very large amount of data, users widely regard this serum as an effective, affordable alternative to high-end Vitamin C serums, praising its ability to fade hyperpigmentation and brighten the complexion. While the water-light texture is a hit for oily skin, the product's instability requires fridge storage to prevent rapid oxidation, and the potent formula can be irritating for sensitive skin types.
