## Why this fit

- The formula is highly suitable for your combination skin, with niacinamide and capryloyl salicylic acid providing effective seboregulation and moderate exfoliation to address oily shine.
- The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components like niacinamide and dipotassium glycyrrhizate.
