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

## Why this fit

- Offers high suitability for your oily skin due to niacinamide for seboregulation and glycerin for humectant action, while phenylethyl resorcinol provides moderate brightening and evening of skin tone.
- The serum offers general hydration from glycerin and sodium hyaluronate, which supports oily shine without being targeted for your primary concern.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of prohibited or harsh ingredients.
