Full Review
The hyaluronic acid serum category has a sameness problem. Nearly every brand offers one. They are usually watery, usually unscented, usually positioned as 'the hydrating step,' and usually distinguished only by their molecular weight claims and price point. Farmacy's Filling Good serum walked into this crowded market and decided to be aggressively different — a thick, honey-scented, peptide-loaded formula that treats HA as a foundation rather than a finale.
The texture is the first departure from convention. Where most HA serums feel like slightly viscous water, Filling Good is genuinely rich — a honey-thick liquid that has real slip and body. It glides over the face with a silkiness that feels more serum-oil hybrid than standard hydrator. The consistency is designed for the formula's ambition: this is not just trying to hydrate. It is trying to plump, firm, and signal for collagen production, and the vehicle needs to be substantial enough to carry those actives.
The hyaluronic acid component uses both pure HA and sodium hyaluronate at different molecular weights, which is standard practice in premium HA serums. What is not standard is everything else in the formula. SH-Polypeptide-123 — a vegan collagen peptide bioengineered to mimic human type I collagen — represents genuine formulation innovation. Most collagen in skincare is marine-derived, which creates ethical and efficacy questions. This bioengineered alternative structurally resembles the collagen your skin naturally produces, and while the evidence base for topical collagen peptides is still emerging, the signaling mechanism through which peptides stimulate fibroblast activity is well-supported in the literature.
The encapsulated thyme extract is another unusual choice. Thyme (Thymus vulgaris) is rich in thymol and carvacrol — compounds with antioxidant and anti-inflammatory properties that are often too volatile for effective topical delivery. The encapsulation technology protects these actives until they reach the skin, and Farmacy references a 60-day clinical study showing visible reduction in smile lines and crow's feet. The study details are not independently published, which means taking them somewhat on faith — but the ingredient mechanism is scientifically plausible.
The honey blend — honey extract, propolis, and royal jelly — is where Farmacy's identity comes through most clearly. These are the brand's signature ingredients, and in this serum they serve a genuine purpose beyond branding. Honey is a natural humectant with osmotic properties that draw moisture into the skin. Propolis provides antimicrobial and anti-inflammatory compounds. Royal jelly contains peptides and fatty acids that nourish and condition. Together they create a hydration layer that is richer and more multidimensional than HA alone can provide.
The immediate effect is genuinely impressive. Within minutes of application, skin looks visibly plumper, smoother, and more luminous. Fine lines around the eyes and mouth appear softer — not because they have been structurally filled, but because fully hydrated skin reflects light differently and the swelling effect of HA in the stratum corneum temporarily smooths surface irregularities. This is honest, hydration-driven plumping, and it is real even if it is temporary without consistent use.
The scent is where things get polarizing. Filling Good smells noticeably of honey and thyme. Some users find this warm, comforting, and spa-like. Others find it cloying or artificial. The formula contains Flavor/Aroma as a listed ingredient, which is a curious choice for a brand that positions itself in the clean beauty space. It does not disqualify the product from any clean beauty standard — the ingredient is regulatory shorthand for a complex of aromatic compounds — but it does create a sensory experience that fragrance-sensitive users should be aware of.
The value question is the serum's biggest vulnerability. At $52 for 30ml, it is priced at the upper end of the prestige HA serum market. Excellent HA serums with similar or superior hydration exist for $15-25. What you are paying for beyond basic hydration is the vegan collagen peptide, the encapsulated thyme technology, and the honey complex. Whether those ingredients deliver enough incremental benefit over a simpler HA serum to justify the $30+ premium is a question that will divide cost-conscious skincare consumers from ingredient enthusiasts.
The honest assessment is that Filling Good delivers on hydration and immediate plumping — it does these things very well. Its anti-aging claims are more speculative, resting on emerging ingredients with promising but limited clinical data. For users who want a HA serum that does more than hydrate, that feels luxurious in application, and that aligns with vegan and clean beauty values, it is a thoughtfully formulated product. For users who view HA serums primarily as a hydration step and want maximum value, simpler options exist at lower prices.

Key Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Multi-Molecular Weight Hyaluronic Acid | Two forms of HA — pure hyaluronic acid and sodium hyaluronate — at different molecular weights create layered hydration that plumps both the skin surface and deeper epidermal layers. The dual-weight system is designed to provide both immediate visual plumping and sustained deeper hydration that persists beyond initial application. | well-established |
| SH-Polypeptide-123 (Vegan Collagen Peptide) | A bioengineered vegan collagen peptide that mimics human type I collagen structure. In this serum, it provides structural support to the extracellular matrix without relying on animal-derived collagen, working alongside the hyaluronic acid to address fine lines through both hydration and peptide signaling. | emerging |
| Encapsulated Thyme Extract (Thymus Vulgaris) | A proprietary encapsulated botanical extract clinically shown to reduce the appearance of smile lines and crow's feet after 60 days. The encapsulation technology protects the thyme's active compounds until they reach the skin, providing more targeted antioxidant and anti-aging activity than standard herbal extracts. | emerging |
| Honey Blend (Honey Extract + Propolis + Royal Jelly) | A triple honey complex providing humectant hydration (honey extract), antimicrobial and anti-inflammatory protection (propolis), and growth-factor-rich nourishment (royal jelly). The combination creates a soothing hydration layer that distinguishes this serum from standard HA serums that rely solely on hyaluronic acid for moisture. | promising |
| Dipalmitoyl Hydroxyproline | A collagen-building amino acid derivative that stimulates the skin's own collagen production. Works synergistically with the vegan collagen peptide — one signals for new collagen synthesis while the other provides structural mimicry, creating a two-pronged approach to firmness. | promising |

Evidence
Science & Expert Perspective
The Science
Hyaluronic acid's hydrating mechanism is among the most well-characterized in cosmetic science. Each HA molecule can bind up to 1,000 times its weight in water, and its efficacy is enhanced when delivered at multiple molecular weights. Research published in the Journal of Clinical and Aesthetic Dermatology (2014) demonstrated that multi-weight HA formulations provided superior hydration retention compared to single-weight formulations, with low-molecular-weight HA penetrating deeper into the stratum corneum while high-molecular-weight HA formed a hydrating film at the surface.
SH-Polypeptide-123 represents a newer class of bioengineered peptides designed to mimic human collagen structure. While topically applied collagen cannot penetrate deep enough to replace dermal collagen directly, peptide fragments can act as signaling molecules that stimulate fibroblast activity and collagen synthesis. Research on collagen-derived peptides published in the Journal of Cosmetic Dermatology (2019) showed that specific peptide sequences can upregulate type I collagen expression in dermal fibroblasts — supporting the theoretical mechanism behind vegan collagen peptides.
Propolis and honey extracts have documented antioxidant and wound-healing properties. A comprehensive review in Evidence-Based Complementary and Alternative Medicine (2017) confirmed that propolis demonstrates anti-inflammatory, antimicrobial, and antioxidant effects through its flavonoid and phenolic acid content. Royal jelly's bioactive peptides — particularly royalactin — have been shown in laboratory studies to promote cell proliferation, which may support the regenerative claims of honey-based skincare formulations.
Dipalmitoyl hydroxyproline is a lipid-conjugated form of hydroxyproline, the amino acid most abundant in collagen. By lipophilizing the amino acid, the ingredient's skin penetration is enhanced compared to free hydroxyproline. While clinical data on this specific derivative is limited, the biochemical rationale is sound: providing the building blocks for collagen synthesis in a form that the skin can readily absorb and utilize.

Dermatologist Perspective
Dermatologists recognize hyaluronic acid as one of the most universally recommended hydrating ingredients in topical skincare. Board-certified dermatologists note that multi-molecular-weight HA formulations provide more comprehensive hydration than single-weight alternatives. The addition of vegan collagen peptides is viewed as an interesting formulation choice — while the evidence base for topical peptide signaling is still developing, the mechanism through which short-chain peptides stimulate fibroblast activity is biologically plausible. Dermatologists would likely note that the anti-aging benefits attributed to the encapsulated thyme extract and vegan collagen are incremental improvements over basic HA hydration rather than dramatic interventions. For patients primarily seeking hydration, a simpler HA serum may offer comparable results at lower cost. For patients interested in a multi-active approach, this formula provides a reasonable combination of hydrating and anti-aging ingredients.
Guidance
Usage Guide
How to Use
Dispense 3-4 drops onto fingertips and apply to clean, slightly damp skin. Pat gently across the face, neck, and eye area (avoiding direct contact with eyes). Follow immediately with a moisturizer to seal in hydration — this is critical, as HA without an occlusive layer can draw moisture from the skin in dry environments. Use morning and evening for best results. In the AM, follow with SPF. In the PM, can be layered under retinol or sleeping masks.
Value Assessment
At $52 for 30ml, Filling Good is among the more expensive HA serums at Sephora. Excellent multi-weight HA serums exist at $15-25, making the premium significant. What justifies some of the markup is the ingredient innovation — the vegan collagen peptide, encapsulated thyme, and triple honey complex are not found in cheaper alternatives. A 5ml travel size is available for trial. Two to three months of twice-daily use puts the monthly cost at $17-26, which is steep for a hydrating serum but reasonable if you view it as a combined hydration and anti-aging treatment. For those who want HA plus anti-aging actives in one step, the consolidation may offset the cost by replacing a separate peptide serum.
Who Should Buy
Anyone prioritizing hydration and early anti-aging in a vegan, clean-formulated serum. Ideal for dry, normal, and combination skin types who want more than basic HA hydration and appreciate the honey-thyme sensorial experience. Well-suited for vegan consumers who want a collagen-boosting serum without marine or animal-derived ingredients.
Who Should Skip
Fragrance-sensitive users — the honey and thyme scent is noticeable and the formula contains Flavor/Aroma. Also skip if you view HA serums purely as a hydration step and want maximum value — simpler, equally effective HA serums exist at a fraction of this price. Those with very reactive skin should patch test due to the botanical extracts and benzyl alcohol.

Myth vs. Reality
Myths & Misconceptions
Myth
Vegan collagen is just a marketing gimmick — collagen has to come from animals to work.
Reality
SH-Polypeptide-123 is a bioengineered peptide that mimics the structure of human type I collagen. While it does not replace the body's own collagen production, it can signal for increased collagen synthesis and provide structural support in the extracellular matrix — similar to how animal-derived collagen peptides function in topical application.
Myth
All hyaluronic acid serums are basically the same.
Reality
HA serums differ significantly in molecular weight distribution, supporting ingredients, and delivery systems. This formula combines HA with vegan collagen peptides, encapsulated thyme extract, and a honey-propolis-royal jelly complex — a combination that extends well beyond basic HA hydration into anti-aging territory.
FAQ
Frequently Asked Questions
Does the Farmacy Filling Good serum really plump fine lines?
The hyaluronic acid provides immediate visible plumping through hydration — fine lines appear softer when skin is fully hydrated. The vegan collagen peptide and encapsulated thyme extract target longer-term improvement. Clinical studies show visible reduction in smile lines and crow's feet at 60 days. Results are real but primarily hydration-driven in the short term.
Is the Farmacy Filling Good serum fragrance-free?
No — despite Farmacy's clean beauty positioning, this serum contains Flavor/Aroma as a listed ingredient, and the honey and thyme extracts contribute a noticeable scent. If you are fragrance-sensitive, this may not be suitable.
Can I use the Farmacy Filling Good serum with retinol?
Yes — hyaluronic acid serums pair excellently with retinol. Apply retinol first on dry skin, wait a few minutes, then layer this serum to provide the hydration that retinol tends to strip. The honey and propolis in the formula add soothing benefits that help buffer retinol irritation.
What is vegan collagen and does it actually work?
SH-Polypeptide-123 is a bioengineered peptide that mimics human type I collagen structure without using animal sources. While it cannot replace lost collagen deep in the dermis, topical peptide signaling can stimulate fibroblasts to produce more collagen. It is a legitimate ingredient with emerging evidence, not just a marketing term.
How should I apply hyaluronic acid serum for best results?
Apply 3-4 drops to slightly damp skin — HA is a humectant that draws water in, so damp skin provides moisture for it to bind. Follow immediately with a moisturizer to seal in the hydration. In dry climates, HA without an occlusive layer on top can actually draw moisture out of the skin.
