Numbuzin No.3 Skin Softening Serum and Beauty of Joseon Glow Serum (Propolis + Niacinamide) are both K-beauty serums built for radiance and smoother-looking skin. They often appear in the same “glass skin” routines, but they approach glow differently. Numbuzin leans on fermented ingredients for softness and refinement; Beauty of Joseon relies on propolis and niacinamide for calm, hydrated radiance. Here is how to choose based on skin type and goals.

Ingredient science
Fermented ingredients
Fermented ingredients, such as galactomyces and bifida ferment lysate, are widely used in Korean skincare. Fermentation can break down compounds into smaller molecules and produce amino acids and other substances associated with hydration and a smoother feel. Evidence is mostly from small studies and brand testing, so expect cosmetic softness and glow rather than dramatic change.
Propolis and niacinamide
Propolis is a bee-derived resin used for its soothing and antioxidant properties. Niacinamide at around 2% supports the look of evenness and barrier function. Together they give Beauty of Joseon’s serum an immediate glow with gentle long-term benefits.
Which suits your skin?
| Skin type or goal | Better pick | Why |
|---|---|---|
| Rough texture, dullness | Numbuzin No.3 | Softening, refining focus |
| Dry, dehydrated | Beauty of Joseon | Rich, hydrating texture |
| Oily | Numbuzin No.3 | Lighter finish |
| Redness-prone, sensitive | Beauty of Joseon (if no propolis allergy) | Soothing focus |
| Uneven tone | Beauty of Joseon | Niacinamide support |
| Fungal acne concerns | Check both labels | Some ferments and oils can be triggers |
How to use and layer
Apply either after cleansing and toner, before moisturizer. Use 2–3 pumps or drops and press into the skin. Both can be used morning and night. In the morning, follow with sunscreen.
Using both together
They layer well. A common order is Numbuzin first for texture, then Beauty of Joseon for glow and hydration, then moisturizer. If you notice stickiness, use less of each or split them between morning and evening.
Pairing with actives
- Retinoids: both are gentle companions; apply after the retinoid on sensitive nights.
- Vitamin C: apply vitamin C first, then either serum.
- Exfoliating acids: fine for most, but keep total active load moderate.
What results to expect
Both give a visible glow soon after application, thanks to their textures. Longer-term softness and evenness build over 4–8 weeks of consistent use. Neither replaces sunscreen or evidence-based actives for aging or pigmentation.
How to tell which one your skin prefers
Use one serum alone for three weeks, then the other for three weeks, keeping the rest of your routine unchanged. Note how your skin feels at midday, whether makeup sits better or worse, and whether any new bumps appear. Texture-focused users often notice Numbuzin’s softening first; dry-skinned users usually notice Beauty of Joseon’s comfort first.
Value
Numbuzin’s 50 ml bottle usually works out slightly cheaper per ml and lasts longer. Beauty of Joseon is cheaper per bottle. If you only buy one, pick the one matching your primary goal: texture (Numbuzin) or hydration and calm (Beauty of Joseon).
Who should avoid each
Avoid Beauty of Joseon Glow Serum if you are allergic to bee products, propolis or pollen. Those sensitive to fermented ingredients or yeast should patch test Numbuzin. Anyone prone to clogged pores or fungal acne should review both ingredient lists for potential triggers. Stop use if you notice itching, rash or new breakouts after a week or two.
FAQ
Is Numbuzin No.3 an exfoliant?
It is positioned as a softening, smoothing serum rather than an acid exfoliant. Check the current label if you want to avoid exfoliating ingredients.
Can Beauty of Joseon Glow Serum be used by oily skin?
Yes, many oily-skinned users enjoy it. Use a smaller amount and a light gel moisturizer to avoid excess shine.
Bottom line
Choose Numbuzin No.3 Skin Softening Serum if your priority is smoother, more refined-looking texture with a lighter feel. Choose Beauty of Joseon Glow Serum if you want hydration, calm and glow with gentle niacinamide support, provided you are not allergic to propolis. They also layer well together for glass-skin routines.
