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.

A great choice for skin with dark spots; a few toners fit it even better.

## Why this fit

- Offers moderate exfoliation for pigmentation and is highly suitable for your normal skin due to the presence of mandelic acid, which gently exfoliates and promotes skin renewal while beta-glucan and panthenol support hydration and barrier function.
- Glycyrrhiza glabra root extract and centella asiatica extract further contribute to soothing and calming the skin, enhancing the overall comfort and efficacy for your skin concerns.
- The formulation is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

Mandelic acid helps fade dark spots and uneven skin tone while being generally gentle on the skin. It works by gently exfoliating the outer layer to reveal fresher, more even skin underneath.
