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.

A great choice for mature skin; a few serums fit it even better.

## Why this fit

- This serum is highly suitable for your normal skin, as niacinamide and tocopherol work synergistically to provide antioxidant activity and support barrier repair, addressing your concerns about wrinkles and fine lines. Adenosine further aids in promoting collagen production and improving skin texture, enhancing its effectiveness for anti-aging.
- The formulation also includes arbutin and glutathione, which contribute to brightening and evening skin tone, offering additional benefits beyond your primary goal.
- The product is safe for your skin, with no reported risks of irritation due to the absence of harsh or prohibited ingredients.
