Almost every firming serum is a peptide-and-humectant story; this one is built around a patented copper-zinc malonate complex that a Jefferson Medical College biopsy study found increased new elastin synthesis in photoaged facial skin within six weeks. That is a different, better-documented mechanism than most of the category, and it is the reason a formula this short can carry a physician-dispensed price.
A rare firming serum with a real, published mechanism, a copper-zinc malonate complex shown on biopsy to prompt new elastin, wrapped in a thin alcohol-silicone vehicle that does little else. The bounce-back some users report after a couple of months is plausible; the instant tightness is a film. At $220 for 30 ml, it is a specialist purchase for people who want the elastin story and can afford to test it.
This assessment rests on six years of physician-channel sales, a few hundred reviews and a peer-reviewed biopsy study of the copper-zinc malonate complex rather than of this serum specifically. The eight-week firmness and crepiness percentages Obagi quotes come from a blinded consumer study held on file at the company and report participant perceptions, not measured elasticity.
Listed for Aging and Sun Damage — the actives here (Glycerin, Dimethicone, Emollient Esters, bi mineral contour complex) are in our research queue for those concerns; there is no verdict until their evidence rows are written. That is a gap in our table, not a mark against the product.

There are two kinds of firmness a serum can sell you, and this bottle contains both. The first arrives in under a minute: amodimethicone and dimethicone lay a film across the skin that contracts slightly as it dries, and the face feels smoother and a touch taut. Every firming serum on earth does this, and none of it survives the next cleanse. The second kind is slower and rarer, and it is the reason Obagi charges $220 for 30 ml. The Bi-Mineral Contour Complex, a copper-zinc malonate compound the company has patented, was studied in a Jefferson Medical College biopsy trial and found to increase new elastin synthesis in photoaged facial skin within six weeks. Reading the serum well means holding both firmnesses apart, enjoying the first without paying for it and judging the product on the second.
Obagi has been a physician-dispensed brand since 1988, when dermatologist Zein Obagi built the Nu-Derm system around tretinoin and hydroquinone, and its ELASTIderm eye cream carried the mineral complex for years before the company extended it to a full-face serum around 2020. In its 2025 relaunch Obagi simplified its names by function, so the ELASTIderm Facial Serum is now labelled Firming Facial Serum; same bottle, same formula, same price. Six years of physician-office sales and a few hundred reviews have given it a steady, if not rapturous, following.
The formula is short and almost entirely vehicle. Water, glycerin, methylpropanediol and denatured alcohol lead, then dimethicone and three light ester emollients, a glycol, a preservative, two thickeners. Malonic acid sits thirteenth, and the two mineral salts, zinc carbonate and copper carbonate hydroxide, are near the end just before the fragrance. Those three ingredients are the complex; everything else exists to deliver them in a thin, fast-setting serum. There is no peptide, no vitamin, no antioxidant, no second mechanism. That is either admirable focus or a very expensive single idea, depending on whether the idea works.
The evidence that it might is unusually specific for a cosmetic. The 2009 Experimental Dermatology study applied a 0.1% copper-zinc malonate cream twice daily to 21 women with photoaged faces and took biopsies at baseline and six weeks. Histology showed regenerating elastic fibres extending toward the dermo-epidermal junction, immunofluorescence for newly made, uncrosslinked tropoelastin was significantly higher, and desmosine, a cross-link found only in elastin, confirmed accumulation. The proposed mechanism is that copper and zinc are cofactors for lysyl oxidase, the enzyme that cross-links elastin and collagen. It is a small, open study with authors connected to the product, and it is also a real biopsy study with a real biochemical endpoint, which is more than almost any competitor in this category can say. Obagi's own eight-week blinded study, held on file, reported that every participant thought their face looked firmer and most saw less crepiness; that is consumer perception and should be read as such.
In use it is undemanding. Two or three pumps of a thin, milky serum spread quickly, set in a minute and leave a smooth veil that layers under moisturizer and sunscreen without pilling. The alcohol gives a brief coolness; the fragrance, last in the list, is light and gone fast. It adds no irritation to a tretinoin routine, which is why Nu-Derm patients are the people most often handed it. Over two to three months, the users who like it describe the thing the study would predict: not a lift, but a change in how the skin recovers when pressed, a little more spring at the jawline and under the cheekbones. Users who do not like it describe the same texture and no change, and at this price that is an expensive way to find out which group you are in.
It is worth being precise about what the study did and did not show, because the price rides on it. Twenty-one women, no placebo arm, six weeks, and endpoints measured in the dermis rather than in the mirror: more tropoelastin, more desmosine, fibres visible on histology. That is evidence that the compound does something biochemically real in human skin. It is not evidence that the something is large enough to see, or that it persists, or that this serum's vehicle delivers the compound as well as the study cream did. A patient who understands that distinction is the right buyer; a patient who reads 'clinically proven' and expects a lift is not.
The objections are straightforward. Denatured alcohol is fourth in the list and fragrance is present, two things a $220 serum from a clinical brand ought to have designed out. The esters are mild comedogenic risks on very congestion-prone skin. There is nothing here for tone, texture or antioxidant protection, so it cannot be anyone's only serum. And the arithmetic is unkind: two to three pumps twice a day empties the bottle in six to eight weeks, so a three-month trial costs $330 to $440 for one mechanism.
Who it suits is a narrow group. Someone with photoaged, slackening skin who already has retinoid, vitamin C and sunscreen in place, wants to add a mechanism none of those address, and can afford to run the experiment for a season will find this the most credibly evidenced elastin product they can buy without a prescription. Anyone still building the basics, or hoping for a visible lift, or working to a budget, should spend the money on the retinoid first; it does more, for less, with far more proof.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Bi-Mineral Contour Complex (Malonic Acid, Zinc Carbonate, Copper Carbonate Hydroxide) (0.1% copper-zinc malonate (per published study of the complex)) | Obagi's patented pairing of copper and zinc with malonic acid, listed in the back third but present at the roughly 0.1% studied in the biopsy work on elastin synthesis. In this face serum it is the entire firming rationale: the minerals are meant to act as cofactors for elastin cross-linking so the skin builds back some of the elastic fibre network photoaging strips away. | Not yet assessed |
| Glycerin | Second in the list, glycerin is the humectant that gives this otherwise sparse serum its immediate plumping and keeps the alcohol-carried minerals from leaving the skin tight. | Not yet assessed |
| Amodimethicone + Dimethicone | A film-forming silicone pair that leaves a smooth, slightly tightening veil on the surface, which is where the instant 'firmer' feel comes from before any elastin work could possibly show; amodimethicone in particular is a substantive silicone more often seen in hair conditioners. | Not yet assessed |
| Isocetyl Stearoyl Stearate + Coco-Caprylate/Caprate | Light ester emollients that carry the mineral complex in a serum rather than a cream texture and give slip without heaviness, so the product layers under a moisturizer twice a day. | Not yet assessed |

AM & PM
Two to three pumps on clean, dry skin morning and night, before moisturizer and sunscreen. It contains no retinoid or acid, so it sits under a tretinoin or Obagi retinol at night; apply the serum first and let it set for a minute.
An immediate smoothing and a faint tightening from the silicone film. Obagi's blinded study reported firmer-looking, less crepey skin at eight weeks, and the biopsy work on the complex showed new elastin at six weeks; three months of twice-daily use is a fair trial before judging whether the bounce-back is more than the film.
The serum is a delivery system for one compound, and that compound has a better paper trail than most cosmetic actives. Photoaged skin loses functional elastic fibres, and the idea behind copper-zinc malonate is to supply the mineral cofactors that lysyl oxidase needs to cross-link newly made tropoelastin into mature elastin. A 2009 study in Experimental Dermatology from Thomas Jefferson University tested a 0.1% copper-zinc malonate cream in 21 women with photoaged facial skin, taking biopsies at baseline and after six weeks of twice-daily use. Histopathology showed evidence of elastic fibre regeneration, including fibres extending perpendicularly toward the dermo-epidermal junction in the papillary dermis; semi-quantitative immunofluorescence with an antibody specific to newly synthesised, uncrosslinked tropoelastin showed a statistically significant increase in elastin biosynthesis; and a desmosine assay, measuring an elastin-specific cross-link, confirmed accumulation of elastic fibres. The authors concluded the compound has the propensity to increase elastin synthesis in human skin in vivo and that this may contribute to the wrinkle effacement seen in its clinical trials. It is a small, uncontrolled study with industry connections, and it is also a biopsy study with a biochemical endpoint, which places it well above the consumer-perception data that supports most firming products.
The rest of the formula is vehicle. Glycerin provides humectancy and immediate plumping; denatured alcohol and methylpropanediol act as solvents and penetration aids for the mineral salts; dimethicone and amodimethicone form the surface film responsible for the instant smoothing and slight tightening, amodimethicone being a substantive amine-functional silicone more common in hair conditioners; and the three ester emollients supply slip in a serum rather than a cream base. Zinc carbonate and copper carbonate hydroxide with malonic acid constitute the complex, and their position near the end of the list is consistent with the roughly 0.1% studied. There is no antioxidant, peptide or pigment-modulating ingredient, so the product's benefits, if any, are confined to elasticity. Obagi's 2019 twelve-week blinded study, with its eight-week figures on firmness, crepiness, elasticity and bounce-back, is described as data on file and reports participant perceptions rather than instrumental or histological measures.
Among physician-dispensed firming products, the ELASTIderm complex occupies an unusual position because it has a human biopsy study with an elastin-specific endpoint, which is the sort of evidence clinicians look for and rarely find in this category. That said, most dermatologists would frame it as an adjunct: the interventions with the strongest evidence for photoaged, lax skin remain a topical retinoid, daily broad-spectrum sunscreen and, where appropriate, in-office energy-based treatments, and a serum aimed at elastin is a reasonable addition once those are in place rather than a substitute for them. It is commonly paired with Nu-Derm or a retinol because it adds no irritation, which is part of its clinical appeal. The reservations are formulation-based: denatured alcohol and fragrance are avoidable in a product for mature, often sensitised skin, and practitioners would typically warn rosacea-prone or eczema-prone patients to patch test. Expectations also need setting, since the elastin effect, if it occurs, is a gradual change in resilience rather than a visible lift, and the immediate tightening is a cosmetic film. For a patient with the basics covered and the budget, it is a defensible recommendation.
Use morning and evening on clean, dry skin. Dispense two to three pumps, spread over the face and neck with the fingertips, and let the serum set for about a minute until the faint film has formed. In the morning follow with moisturizer and a broad-spectrum sunscreen, since sun exposure is what degrades the elastin the serum is trying to rebuild. At night, apply it before a retinol or tretinoin and then moisturize; it adds no irritation, but on nights the retinoid stings, skipping the serum is fine. Patch test on the jawline if you react to fragrance or alcohol. Commit to twice-daily use for at least eight to twelve weeks before judging, and assess firmness by how the skin springs back when gently pressed rather than by the immediate tightness after application. Keep the pump bottle capped and out of heat.
Two hundred and twenty dollars for 30 ml is among the highest prices in the serum category, and Obagi's recommended two to three pumps twice daily empties the bottle in six to eight weeks, so the running cost is well over $100 a month. What the money buys is a patented copper-zinc malonate complex with a genuine biopsy study, physician-dispensed provenance and a pleasant, layerable texture; what it does not buy is any second mechanism, since the rest of the list is glycerin, alcohol, silicones and esters worth very little. Cutting to two pumps once a day stretches a bottle to three months and roughly halves the monthly cost without, on the evidence, obviously compromising the mechanism, though that is below the twice-daily regimen in the study. There is only one size. For someone with the rest of an anti-aging routine in place who specifically wants the elastin story, the price is high but honest about what it is; for anyone else, a retinoid delivers more proven benefit for a fraction of the money.
People with photoaged, slackening skin who already use a retinoid, sunscreen and an antioxidant and want to add a serum aimed specifically at elastic fibres, with a published mechanism rather than a peptide promise. Obagi Nu-Derm or ELASTIderm Eye Cream users looking for the face counterpart, and anyone with the budget to run a three-month trial, are the natural audience.
Anyone still building a basic routine should buy a retinoid and sunscreen first, since they do far more for far less. Sensitive, rosacea-prone or fragrance-reactive skin should be wary of the alcohol and parfum, very congestion-prone skin may not like the esters, and anyone expecting a visible lift from a serum will be disappointed by a mechanism that works in resilience, not contour.

All Year
Obagi introduced the ELASTIderm Eye Cream with its Bi-Mineral Contour Complex in the late 2000s, after a Jefferson Medical College study of the copper-zinc malonate compound, and extended the complex to a full-face serum around 2020. In its 2025 relaunch Obagi simplified product names by function, so the ELASTIderm Facial Serum is now sold as Firming Facial Serum under the ELASTIderm banner.
Obagi was founded in 1988 by dermatologist Zein Obagi and has been a physician-dispensed brand for nearly four decades, with its Nu-Derm and ELASTIderm lines fixtures in US dermatology and aesthetic practices. The copper-zinc malonate complex in this serum has a peer-reviewed biopsy study behind it; the serum's own eight-week figures are from a blinded study held on file at Obagi rather than published.
The tightness you feel right away is the serum firming your skin.
That is amodimethicone and dimethicone forming a film that contracts slightly as it dries. The elastin mechanism the product is sold on works over weeks and shows as better bounce-back, not as an instant pull. Both are real; only one is the reason to pay for it.
Copper and zinc in a serum will build collagen like a copper peptide does.
The complex here is a copper-zinc malonate, not a copper peptide, and the published work on it measured elastin, not collagen. Its proposed role is as a cofactor for lysyl oxidase in elastic fibre cross-linking; collagen claims belong to other products.
Yes. Obagi renamed its products by function in its 2025 relaunch, and the ELASTIderm Facial Serum is now sold as Firming Facial Serum under the ELASTIderm line, with the same 30 ml bottle, the same Bi-Mineral Contour Complex and the same $220 price.
Malonic acid with zinc carbonate and copper carbonate hydroxide, a copper-zinc malonate compound. A 2009 biopsy study in Experimental Dermatology of a 0.1% copper-zinc malonate cream in 21 women with photoaged skin found significantly increased new elastin synthesis and regenerating elastic fibres after six weeks of twice-daily use.
Yes, and many Obagi Nu-Derm users do. It contains no retinoid or acid, so it layers under tretinoin at night without adding irritation; apply the serum first, wait a minute, then the tretinoin, then moisturizer. Sensitive skin may want to skip it on the nights the retinoid stings.
Obagi's eight-week blinded study is when all participants reported a firmer-looking face and most saw less crepiness. The elastin biopsy work showed new fibres at six weeks. Give it three months of twice-daily use before deciding, and discount the instant tightness, which is the silicone film.
Yes. Parfum is the last ingredient, alongside denatured alcohol high in the list. Rosacea-prone or fragrance-reactive skin should patch test; the eye cream in the same line is the gentler entry point.
Only if the elastin mechanism is what you want, because the rest of the formula is glycerin, silicones and esters that cost very little. A bottle lasts six to eight weeks at Obagi's dose, so the running cost is over $100 a month, which puts it among the most expensive serums per benefit on the market.
