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 suitability for your oily skin due to ingredients like Chlorogenic Acids and Camellia Sinensis Leaf Extract providing antioxidant activity, but it lacks sufficient ingredients for strong seboregulation to address oily shine.
- The serum provides excellent protection against environmental stressors with antioxidants such as ergothioneine and tetrahexyldecyl ascorbate, and general hydration from glycerin, which are supportive for oily skin.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of harsh ingredients and the presence of soothing components like Bisabolol and Licorice Root Extract.
