Description

Who’s It For

Individuals with oily, combination, or acne-prone skin who want to control excess oil, smooth skin texture, minimize the appearance of pores, and tackle post-acne marks — all in a lightweight, non-sticky formula.

Introduction

This is a highly concentrated serum featuring 15% niacinamide, complemented by acetyl glucosamine, zinc PCA, and allantoin. Together, these ingredients help regulate sebum, soothe inflammation, visibly fade hyperpigmentation, support collagen production, and refine skin tone and texture — without clogging pores or feeling heavy on the skin.

How to Use It

  • Use after cleansing, during the serum step of your routine.
  • Apply a few drops to your face.
  • Gently massage using fingertips, moving from the center outward until fully absorbed.
  • It can be used morning and/or night — just be sure to follow daytime use with SPF 30 or higher.
  • Avoid pairing it directly with high-concentration vitamin C to reduce irritation risk; it does work well with BHA or propolis.
