The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Canada.

Brand: [Isntree](https://lovi.care/skincare/ca/brands/isntree)
Category: [Serums and treatments](https://lovi.care/skincare/ca/best/serums)

This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

One of the best serums for skin with dark spots.

## Why this fit

- This product is highly suitable for your normal skin, as Bifida Lysate Ferment and Beta-Glucan work synergistically to significantly enhance skin barrier resilience and hydration. Niacinamide and Willow Bark Extract offer additional benefits by regulating melanogenesis and providing mild exfoliation, supporting overall skin health.
- While the formula provides excellent general skincare benefits, it does not specifically target your primary concern of pigmentation as effectively as a dedicated treatment would.
- The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components like Allantoin and Panthenol.
