This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate benefits for your normal skin with sensitivity, as niacinamide and acetyl glucosamine work to even skin tone and minimize pores, while allantoin and dipotassium glycyrrhizate provide soothing support for redness and irritation.
- The formulation is highly suitable for normal skin types, with ingredients like niacinamide and allantoin supporting anti-inflammatory actions and barrier repair.
- The safety profile is excellent, with no risks of irritation due to the absence of prohibited or harsh ingredients.
