A Targeted Brightening Serum with 2% Alpha-Arbutin & 68% Rice Bran Water
A lightweight brightening serum designed for dark spots, uneven skin tone and dull-looking skin.
Beauty of Joseon combines 2% alpha-arbutin with 68% rice bran water, supported by niacinamide, panthenol and humectants. The result is a targeted pigmentation serum that also provides hydration rather than focusing exclusively on strong treatment actives.
Why We Chose It
We chose Glow Deep Serum because alpha-arbutin gives practitioners another evidence-supported pathway for addressing the appearance of pigmentation.
Not everyone wants—or needs—the same pigmentation ingredient. While other products in the Glass Ritual collection use tranexamic acid, vitamin C, kojic acid or multi-active combinations, this serum places 2% alpha-arbutin at the centre of the treatment.
The large proportion of rice bran water and supporting hydrating ingredients also makes it particularly useful for practitioners who want targeted brightening care without abandoning hydration.

Who It's For
Consider this serum if you are concerned about:
- Dark spots
- Post-blemish marks
- Uneven-looking pigmentation
- Dullness
- Uneven skin tone
- Pigmentation accompanied by dryness or dehydration
- Adding alpha-arbutin to your routine without using several separate brightening serums
Individual responses to brightening ingredients vary. Pigmentation can also have different causes, so no single cosmetic ingredient is appropriate for every type of discolouration.
How to Use
After cleansing and toning, apply 2–3 drops evenly over the face. Gently pat until absorbed, then follow with moisturiser.
During the daytime, appropriate sun protection is particularly important when managing pigmentation.
Ritual Position
Cleanse → Tone → Treat with Glow Deep Serum → Moisturise
Use during the treatment stage of your Glass Ritual.
Glass Ritual Pairing
Glow Deep Serum can serve as the primary brightening serum in a simple pigmentation ritual. Pair it with a gentle cleanser, supportive toner and moisturiser rather than automatically layering several pigmentation serums together.
If you already use exfoliating acids, retinoids or other concentrated treatments, introduce combinations gradually and observe your skin's response.
Glass Ritual Principle: Choose ingredients with purpose. You do not need every brightening active in the same routine.

Safety & Ingredient Information
For external use only. Avoid direct contact with the eyes and discontinue use if irritation occurs.
Patch testing is recommended when introducing a new active product, particularly for sensitive or reactive skin.
