This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other serums fit it better.

## Why this fit

- Offers moderate brightening and evening of skin tone for your oily skin due to the presence of 3-0-Ethyl Ascorbic Acid and Niacinamide, which also offer seboregulation and antioxidant activity.
- While Allantoin and Camellia Sinensis Leaf Water provide general hydration and soothing benefits, they are less relevant to your primary concern of reducing oily shine.
- The product is safe for your oily skin, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components like Niacinamide and Allantoin.

- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
