This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for combination skin; other serums fit it better.

## Why this fit

- Offers moderate brightening and evening of skin tone for your combination skin, as niacinamide and sodium ascorbyl phosphate improve skin tone and offer antioxidant activity. Glycerin and allantoin provide general hydration and soothing benefits, which are supportive but not targeted for your oily shine concerns.
- The formula is highly suitable for combination skin due to the presence of niacinamide and sodium ascorbyl phosphate, which regulate melanogenesis and provide antioxidant activity.
- The safety profile is excellent, with no risks of irritation for your combination skin due to the absence of prohibited or harsh ingredients.
