Glow Serum: Propolis + Niacinamide

$18·30 ml·~$11/mo to use

Reviewed by SerumTruth Editorial · Updated July 2026

A dewy, well-priced glow serum that leans on a big dose of propolis with a supporting 2% niacinamide. The niacinamide is the better-evidenced half; propolis is a pleasant, limited-evidence conditioner. A nice-to-use layer, not a corrective treatment.

SerumProof score74 / 100
  • Evidence17 / 30

    Strength of the research behind the key actives

    • Propolis Extract: limited evidence
    • Niacinamide: moderate evidence
    • Score is the average of the key actives’ evidence grades.
  • Potency21 / 25

    Dosed at studied levels, not fairy-dusted

    • Propolis Extract (60%): dosed at a studied level
    • Niacinamide (2%): dosed at a studied level
    • Potency tracks how strongly the actives are dosed, led by the strongest, not how many there are.
  • Delivery & stability14 / 20

    Delivery tech + packaging that protects fragile actives

    • Delivery: standard
    • Packaging: clear dropper
    • No fragile actives here, so packaging barely moves the score.
  • Formulation8 / 10

    Disclosure, active breadth, and ingredient generation

    • 2 of 2 actives disclose a concentration
    • 2 key actives (breadth credit caps at 3)
    • Current-generation or synergistic: Propolis Extract
  • Value14 / 15

    What a month of use costs vs. the category

    • About $11 per month to use
    • $18 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
    • Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside

ActiveDisclosedDose
Propolis Extract60%Studied
Niacinamide2%Studied

Propolis extract as the hero, brand-stated at 60%, with 2% niacinamide and a low level of betaine salicylate, in a frosted glass dropper. It is aimed at the appearance of a dewy, comfortable and more even-looking complexion, the niacinamide adding tone and shine support. It is not vegan, and propolis is a known allergen for some, so patch testing is sensible.

How it’s delivered

DeliveryStandardPackagingClear dropper

Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
