The full review.
Most propolis serums list the ingredient in the middle of the INCI list at 10 or 20 percent, buffered by water and glycerin. Bonajour changed this. They put propolis extract in the first slot at 80 percent and built a water-free serum around it. This creates one of the densest propolis formulas available. It is why this small Korean indie brand appeared on acne-subreddit wishlists years before most Western retailers could spell Bonajour correctly.
Propolis is the resinous material honeybees collect from tree buds to seal hives. It contains flavonoids, phenolic acids, and terpenes. Research shows it has antibacterial and anti-inflammatory activity, making it useful for breakout-prone skin that cannot handle stronger actives. At 80 percent concentration in a water-free serum, it acts as a flavonoid bath for your face.
Texture
The texture proves this isn’t a standard serum. It is a clear, pale-amber jelly that holds its shape on the dropper before turning almost water-thin on the skin. It feels tacky for about thirty seconds, then absorbs into a soft glazed finish that works under moisturizer and sunscreen.
Scent
The scent is faint, natural, and honey-adjacent. It dissipates quickly.
Works for
The formula manages active inflammation. Users with reactive, acne-prone, or post-procedure skin report that breakouts look calmer within days and redness quiets down over the first couple of weeks. The supporting ingredients—green tea, willow bark, saccharomyces ferment, and botanical extracts—reinforce the anti-inflammatory profile. It contains no oils, butters, or fatty esters that could congest skin or trigger fungal flares. You can recommend this soothing serum to someone managing both regular acne and seborrheic dermatitis.
Not ideal for
It is less effective as a standalone hydrator for dry skin. The humectants are restrained and there is no occlusive layer to lock in moisture. Dry-skinned users expecting a glycerin-and-HA cocktail may feel underwhelmed. It works better when paired with a ceramide moisturizer, as it is a treatment serum first and a hydrator second.
Conflicts With
Regarding the vegan question: Bonajour uses plant-forward imagery, but propolis is a bee-derived ingredient. It is cruelty-free but not vegan. Avoid this category if you avoid bee products for ethical reasons. People with bee or honey allergies should patch test first; propolis can provoke contact reactions in sensitized individuals, and the risk is real at this concentration.
Value
The serum excels in value. A 100ml bottle costs between 15 and 22 dollars depending on the retailer and sale. This is roughly double the size of most comparable K-beauty propolis serums at a lower price, and much cheaper than a Western soothing serum in this category. The cost-per-milliliter is excellent for a budget-friendly, acne-prone routine.
Best for
This is not a hero-active serum like vitamin C or retinol; it won’t fade hyperpigmentation or rebuild collagen. Instead, it buffers reactive skin, reduces visible inflammation from breakouts, and works as a calming step alongside stronger actives. In a category driven by marketing, using more of the ingredient is the innovation.

The science.
The Science
Propolis has attracted real scientific interest over the past decade for its antibacterial, anti-inflammatory, and wound-healing potential. Its activity comes from a complex mix of flavonoids (notably pinocembrin and chrysin), phenolic acids like caffeic acid, and various terpenes, though the exact profile varies significantly with geographic origin and bee species. In vitro studies have repeatedly shown activity against Cutibacterium acnes and Staphylococcus aureus, the two bacteria most implicated in inflammatory acne, and several small clinical studies have reported improvements in acne lesion counts when propolis is used topically over 4–8 weeks.
What makes this specific formulation interesting is the concentration. Most commercial propolis products use the ingredient at 5–20%, where the flavonoid dose delivered to skin is modest. At roughly 80%, Bonajour is essentially maximizing the flavonoid payload while skipping the water phase entirely — an approach more common to essence-style Korean products than Western serums. The supporting ingredients aren't incidental either: green tea's epigallocatechin gallate and the willow bark salicin both contribute independent anti-inflammatory mechanisms, while saccharomyces ferment contributes amino acids and peptides that support barrier recovery. The combination targets inflammation through multiple parallel pathways rather than relying on any single active.
The limitation worth being honest about is that most propolis research to date has been in vitro or in small clinical populations, and standardized concentration-response data is still lacking. The evidence base is promising rather than definitive, and the ingredient's efficacy will depend somewhat on the specific propolis source used — something no brand, including Bonajour, discloses in detail.
Dermatologist Perspective
Dermatologists generally regard propolis as a reasonable adjunct ingredient for mild inflammatory acne and post-procedure redness, particularly for patients who can't tolerate prescription actives or who want to layer a soothing step into a retinoid-heavy routine. Board-certified dermatologists note that propolis is among the more common sources of allergic contact dermatitis in cosmetic ingredients — roughly 1–3% of patch-tested patients in some European studies — so a patch test before full-face use is commonly recommended, especially for anyone with a known history of bee sting reactions. When tolerated, this serum is frequently cited in K-beauty–savvy derm circles as a gentle anti-inflammatory option that pairs well with benzoyl peroxide, adapalene, or azelaic acid prescriptions without compounding irritation.
Where it fits in your routine.
Apply 2–4 drops to clean, damp skin after toner and before moisturizer, morning and night. Press the jelly texture into your skin instead of rubbing. It layers well under vitamin C in the morning or after retinol at night to buffer irritation. If you have bee, pollen, or honey sensitivities, patch test on your inner forearm for 48 hours before full-face use. Store away from direct sunlight and use within 12 months of opening.
At roughly $15–22 for 100ml, Bonajour Propolis Serum offers one of the best per-milliliter values in the soothing-serum category. Better-known K-beauty propolis serums usually cost $25–35 for 50ml, so Bonajour provides double the product for two-thirds the price. The 100ml size works for twice-daily full-face use; most users find a bottle lasts 4–6 months. No larger size exists, but the 100ml bottle is generous for this category. The math favors budget-conscious acne-prone skincare buyers.
Acne-prone, reactive, or post-procedure skin needs a gentle anti-inflammatory serum that won't add irritation from retinoids or exfoliating acids. For anyone building a budget-friendly K-beauty routine, this single hero-concentration soothing product offers unmatched value.
Avoid this if you have a known bee, propolis, or honey allergy. Strict vegans should look elsewhere. Very dry skin types wanting one serum for both hydration and soothing will find this lacks moisture and should pair it with a thicker humectant step.

The backstory.
Bonajour built a small cult following in Korea by stripping formulas down to one star ingredient per product and pushing its concentration as high as possible. The Propolis Serum was the breakout that put the brand on the map internationally, spreading through YesStyle and acne-focused Reddit threads before most Western retailers had even heard of it.
About Bonajour
Established Brand (5–20 years)Bonajour is a Korean indie skincare brand that uses botanical-forward, minimalist formulations. The Propolis Serum has been on the market since at least 2017. It has an established track record in K-beauty communities, but independent clinical validation of its specific formulas is limited.
Common myths.
Propolis is vegan because it's a plant resin
Honeybees collect and process Propolis from plant resins. This makes Propolis bee-derived and not vegan. Bonajour markets itself as natural, but this serum is not for strict vegans.
High propolis percentages cause breakouts because the texture is sticky.
This formula suspends propolis in a lightweight water/glycerin base without heavy oils or butters. Most acne-prone users report no congestion or fungal flares despite the density.
FAQ.
What percentage of propolis is in Bonajour Propolis Serum?
Bonajour markets this serum with roughly 80% propolis extract. Propolis is the first ingredient instead of a typical water base. This concentration is unusually high for a propolis serum, so the formula feels dense on first application.
Is Bonajour Propolis Serum good for acne-prone skin?
Yes — propolis flavonoids, green tea polyphenols, and willow bark salicin target acne inflammation and bacteria without pore-clogging oils. Most users see calmer breakouts within 1–2 weeks.
Is this serum vegan?
No. Honeybees produce Propolis, so this serum is not for strict vegans even though the brand focuses on plants. It is marketed as cruelty-free.
Can I use Bonajour Propolis Serum with retinol or vitamin C?
Yes. The formula is gentle and layers well with active treatments — many users apply it after a vitamin C serum in the morning or after retinol at night specifically to buffer irritation from those actives.
Is Bonajour Propolis Serum fungal acne safe?
Yes — the ingredient list lacks fatty alcohols, esters, or oils that trigger malassezia. This makes it safe for anyone managing fungal acne or seborrheic dermatitis alongside regular breakouts.
Will this serum feel sticky?
It feels slightly tacky for about 30 seconds before it sinks in completely. Some users in very humid climates report lingering tackiness, but it layers cleanly under moisturizer and sunscreen for most people.
