💎 15% Niacinamide for Brightening

The hero ingredient is 15% niacinamide, a high-concentration form of vitamin B3 widely used in skincare for brightening, oil-balance and improving the appearance of uneven skin tone.

If your main concerns are:

Dullness → Dark spots → Uneven tone → Visible pores → Uneven texture

this serum can fit naturally into a targeted brightening routine.

The manufacturer specifically lists dull/dry skin, pigmentation, uneven texture and troubled skin among its target concerns.

🍋 Yuja + Niacinamide Glow

The formula combines niacinamide with Citrus Junos (Yuja) Fruit Oil, creating a brightening-focused Korean skincare combination.

The formula also includes glutathione, tranexamic acid and sodium ascorbyl phosphate, giving the serum additional antioxidant and tone-focused ingredients.

Together, these ingredients make this more than a basic niacinamide serum — it’s positioned as a glow + brightening treatment.

💧 Hydration Without a Heavy Feel

Brightening treatments don’t have to mean a dry-feeling skincare routine.

This formula includes several moisturizing and conditioning ingredients, including:

• Glycerin
• Panthenol
• Squalane
• Sodium Hyaluronate
• Beta-Glucan

These ingredients help support a comfortable, hydrated-feeling complexion.

✨ For Dark Spots & Uneven Skin Tone

If you’re building a routine around the appearance of post-blemish marks, pigmentation or uneven tone, this serum can be used as your targeted brightening step.

For best results, consistency matters. And during the day, sunscreen remains essential when you’re working on pigmentation and uneven tone.

⚠️ For Sensitive Skin

Because this contains a relatively high 15% niacinamide concentration, customers who are new to concentrated niacinamide may want to introduce it gradually.

Patch-test first, particularly if your skin is sensitive or you’re already using multiple active ingredients.
