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.

Works for skin with dark spots; other serums fit it better.

## Why this fit

- This serum offers moderate benefits for your normal skin, with ingredients like Retinal and 3-O-Ethyl Ascorbic Acid working to smooth texture and brighten tone, though these are not the most effective for your primary concern of pigmentation.
- Niacinamide and Panax Ginseng Root Extract provide antioxidant activity and barrier repair, which are supportive for normal skin.
- The product is safe for your normal skin, as it contains soothing ingredients like Bakuchiol and Panax Ginseng Root Extract, and lacks harsh or prohibited substances.
