- Offers moderate brightening benefits with alpha-arbutin and saccharum officinarum extract to help even skin tone, but the primary focus is not on controlling oily shine.
- The product is generally safe for your oily skin, with minimal risk of irritation from ingredients like Alcohol Denat and Menthol.

- 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.

## Questions and answers

### How well does iS Clinical Brightening Serum work for oily skin?

This serum works for oily skin, though other products fit it better because it manages excess sebum with willow bark extract while helping even skin tone, but alcohol and menthol may cause some dryness. A product of this type needs ingredients like niacinamide, zinc PCA, and ferulic acid to control shine and pores while protecting the barrier without irritation.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30022595/)

### Which ingredients make this serum a good fit for oily skin?

Willow bark extract and saccharum officinarum extract make this serum a good fit for oily skin by helping manage excess sebum and keeping pores clear. To work best for oily skin, a product of this type needs ingredients like niacinamide and zinc PCA to control shine and pores comfortably, alongside soothing extracts and barrier supporters.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30022595/)

### What does Alpha-Arbutin do for oily skin?

Alpha-arbutin helps fade dark spots and uneven tone for oily skin while keeping irritation unlikely. It works to brighten the complexion and manage excess pigment effectively.
Sources: [Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/)

### What does Ascophyllum Nodosum Extract do for oily skin?

Ascophyllum Nodosum Extract helps balance oily skin by managing excess oil and keeping the face feeling fresh and clear. This ingredient is unlikely to clog pores and may help soothe redness, leaving skin smooth and comfortable.

### Where does it go in a skincare routine for oily skin?

This treatment goes in the evening routine, as treatments fit best there for simplicity and safety around sun exposure. Oily skin works well with ingredients like willow bark extract and sugar cane extract to manage excess shine, though this product needs extra hydration to offset potential dryness from alcohol and menthol.

### Can I use this serum with retinol, and in what order?

You can use this serum in your routine, but apply your retinol at a different time or on alternating days to help prevent excessive dryness. For this skin type, a product of this type needs soothing ingredients and lightweight moisture to keep the skin calm and balanced while managing shine.

### How often should I use it?

You can use this treatment in your evening routine once a week to start, as oily skin does best when you slowly build up how often you use it. If your skin feels fine and you like the results, you can carefully use it more often. An oily skin routine needs ingredients that manage excess shine and keep pores clear without causing dryness.

### Can this serum clog pores, cause breakouts or purging for oily skin?

This serum is unlikely to clog pores because it contains Willow Bark Extract and Saccharum Officinarum Extract, which help manage excess oil and prevent pore congestion. Reviewers report a low potential for breakouts, though ingredients like Alcohol Denat and Menthol may cause some dryness.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30022595/)
