Glow Serum: Propolis + Niacinamide

$18·30 ml·~$11/mo to use

Reviewed by SerumTruth Editorial · Price and formula checked 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.

What we like
  • Every active discloses its concentration
  • Cheap to use, about $11 a month

  • Evidence17 / 30

    Strength of the research behind the key actives

    • Propolis Extract: limited evidence
    • Niacinamide: moderate evidence

    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

    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.

    Delivery tech plus packaging, and packaging only counts when actives are fragile.

  • 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

    What a month of use costs: full marks at $6 a month or less, the floor at $60 a month or more.

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

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.

The actives, explained

What the research says

Lab testing on human skin models found propolis extract reduced UV related damage markers, suggesting it may help guard against photodamage.

Propolis Extracts Inhibit UV-Induced Photodamage in Human Experimental In Vitro Skin Models. Antioxidants (Basel), 2019. PubMed ↗

Topical 5% niacinamide was linked to more even looking skin tone, softer looking lines, and less visible blotchiness after 12 weeks.

Niacinamide: A B vitamin that improves aging facial skin appearance. Dermatologic Surgery, 2005. PubMed ↗

A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
