      WHY WE ♥
      ▸ With a high concentration of Niacinamide (15%), this serum minimises enlarged pores, regulate oil sebum production, and reduce uneven skin texture.
      ▸ Powered by the hydrating and restorative benefits of squalane, panthenol, and beta-glucan, this formula won’t dry out the skin—even with a high concentration of niacinamide. While other serums can often be drying, this product keeps the skin perfectly balanced. It provides deep hydration and fortifies the moisture barrier to prevent dryness effectively.
      ▸ While simultaneously by combining with Yuja (Citrus Junos) extract, this serum revives back tired and dull skin to a more radiant complexion. It targets deep hyperpigmentation, post acne scarring, and uneven skin tone. In addition with Glutathione and Tranexamic Acid (TXA), a powerhouse ingredient that is an effective treatment for UV-induced spots, PIE, and melasma. 
      ▸ Infused with yuja oil and agar gum capsules, this formula deeply hydrates the skin for an instant, radiant glow.

    • This product is supposed to be alcohol-free, but I am seeing Cetearyl / Cetyl Alcohol, and such on the ingredient list.. Why?

      Not all alchols are bad for your skin. When refering to alcohol-free we would refer to free of Simple Alcohol (Denat, Ethanol, e.d.). Do you want to know more about the differences between these alcohol types, please have a look in our Beauty Class about Ingredients or check out the glossary with common terms used in skincare.
