This fit is calculated for the concerns frequently associated with mature skin: fine lines, wrinkles, and loss of firmness. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for mature skin; other serums fit it better.

## Why this fit

- Offers moderate brightening and evening of skin tone for your normal skin due to Ascorbic Acid and Niacinamide, which provide antioxidant activity and melanogenesis regulation.
- While it offers general hydration and soothing benefits from Glycerin and Panthenol, it is not specifically targeted for your main goal of addressing wrinkles and fine lines.
- The product is safe for your normal skin, with no risks of irritation due to the absence of harsh ingredients and the presence of numerous soothing components.

## What reviewers say
