Description

A concentrated daily serum for blemish-prone, oily-feeling skin, formulated with Niacinamide (15%) as its headline active. It helps balance the look of excess oil, minimize the appearance of congested pores and improve the look of post-blemish marks for a clearer, more even-looking complexion.

Niacinamide is paired with supporting ingredients chosen to work alongside it. Acetyl Glucosamine (NAG) helps smooth rough-feeling texture and supports a more even-looking tone, while Zinc PCA helps keep shine in check through the day. Allantoin and Trehalose add soothing comfort and hydration, so skin stays soft rather than stripped. The lightweight serum glides over damp skin and layers easily under moisturizer, making it a simple, focused step for skin that tends toward breakouts and visible oil.

Benefits
  • Niacinamide (15%) helps improve the look of post-blemish marks and uneven tone
  • Helps minimize the appearance of congested pores
  • Zinc PCA helps balance the look of excess oil and shine
  • Acetyl Glucosamine helps smooth rough-feeling texture for a softer touch
  • Allantoin and Trehalose add soothing hydration so skin feels comfortable
How to Use

After cleansing and toning, smooth an appropriate amount over damp skin, then gently pat until absorbed.

Follow with moisturizer. In the morning, finish your routine with sunscreen.

Seoulistic Tip
  • New to a higher niacinamide level? Start with once a day and increase as your skin gets comfortable.
  • Apply a few drops to the T-zone first if that is where oil and congested pores show up most.
