Peptides: Signal, Carrier, Copper — Which Ones Actually Do Anything?
'Peptides' is one word standing in for a dozen unrelated molecules with wildly different evidence — most serums are hope in a bottle, but a few classes earn their place.
The Prosome Delivery System that slowly releases kinetin and zeatin over 12 hours is genuinely unique — most night creams deliver their actives immediately upon application. Combined with clinical data showing improvement in rosacea symptoms (a claim few night creams can make), this formula occupies a rare space as an anti-aging product that is specifically validated for reactive and sensitized skin.
A thoughtfully formulated night cream built for skin that cannot tolerate conventional anti-aging actives. The kinetin-zeatin complex with ceramides and a sustained-release delivery system delivered clinical results for both aging and rosacea — a rare combination. Discontinued but still worth tracking down.

There is a frustrating gap in skincare that dermatologists know well: the patient who needs anti-aging intervention but whose skin cannot tolerate it. Retinoids cause flaring. AHAs trigger burning. Even vitamin C at standard concentrations can send reactive, rosacea-prone skin into a spiral of redness and irritation. For years, the advice for these patients was essentially to moisturize and wait — or to endure the irritation period and hope the barrier eventually adapts.
Obagi's Gentle Rejuvenation Advanced Night Repair was built to fill that gap, and for the patients who found it, it was something close to a revelation.
The formula centers on kinetin and zeatin — two cytokinins, plant growth factors originally studied for their ability to delay senescence in plant cells. When researchers turned their attention to human skin, they found something genuinely interesting: kinetin demonstrated the ability to reduce signs of photoaging — roughness, fine lines, hyperpigmentation — with minimal to no irritation. It was not as aggressive as retinol, not as dramatic as prescription tretinoin. But for skin that could not handle either, it offered a third path.
Obagi paired the kinetin-zeatin duo with their Prosome Delivery System — a liposomal encapsulation that releases the cytokinins gradually over approximately 12 hours. This is not marketing theater; sustained release is a well-established pharmaceutical approach, and applying it to a night cream means the active ingredients work throughout the overnight repair window rather than dumping their payload in the first hour and declining.
The supporting cast is where this formula truly distinguishes itself from simpler night creams. Three ceramides — NP, AP, and EOP — are included alongside cholesterol and phytosphingosine, recreating the physiological ratio of lipids found in a healthy skin barrier. This is the same structural approach used in CeraVe's ceramide complex, and for good reason: research consistently shows that this trio, in the correct ratio, is among the most effective ways to repair and maintain barrier function. For rosacea-prone skin, where the barrier is almost always compromised, this is not a luxury — it is a necessity.
Palmitoyl tripeptide-5 adds a collagen-stimulating dimension, mimicking the body's own TGF-beta signaling pathway. And ergothioneine — a rare mushroom-derived amino acid antioxidant — provides mitochondrial-level protection against oxidative stress. It is a sophisticated ingredient that you do not see in many night creams, and its inclusion here signals that someone was thinking carefully about what aging skin actually needs at the cellular level.
The clinical trial data, while limited in scope, is compelling. An 86% improvement in roughness is a meaningful outcome for any topical product. But the 80% reduction in rosacea symptoms over 12 weeks is the more remarkable claim — it positions this night cream as one of the very few anti-aging products with validated benefits for reactive skin. That is a claim most brands would not dare to make, and Obagi backed it up with trial data.
On the skin, the cream delivers an experience that matches its clinical positioning. It is lightweight for a night cream — not the thick, blanket-like consistency that many overnight products default to. It spreads easily, absorbs within a minute or two, and leaves a velvety finish that feels comfortable without suffocating. There is no fragrance, no tingling, no sensory indication that active ingredients are at work. For people accustomed to equating sensation with efficacy, this quiet performance might seem underwhelming. For people whose skin panics at the first sign of an active, the silence is the whole point.
Sweet almond oil and jojoba esters provide the emollient base, with glycerin and saccharide isomerate handling the humectant duties. Saccharide isomerate is an underappreciated ingredient — it actually binds to the skin's keratin, creating a persistent moisture reservoir that outlasts typical humectants. This means the hydration you feel at night is still detectable by morning, which is more than many richer-feeling night creams can honestly claim.
The price, at $102 for 1.7 ounces, is premium but not unreasonable for the level of formulation sophistication on display. The ceramide complex alone would be respectable at this price point; adding the kinetin-zeatin technology, sustained-release delivery, and clinical trial validation creates a package that at least attempts to earn the asking price. It is not drugstore value, but it is not empty luxury either.
And then Obagi discontinued it. The Gentle Rejuvenation line has been quietly retired, with the Hydrate Luxe recommended as a replacement — a product that shares some moisturizing qualities but lacks the kinetin-zeatin complex and Prosome technology that made this cream unique. For loyal users, the discontinuation was a genuine loss.
Remaining stock can still be found through some authorized retailers and online sellers. If you have reactive, rosacea-prone, or sensitized skin and you have struggled to find an anti-aging night cream that does not trigger your skin, this is worth seeking out while supplies last. It solved a real clinical problem with genuine formulation intelligence, and the skincare market has not yet produced a clear successor.
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Kinetin-Zeatin Complex | The proprietary duo at the heart of this formula — two plant-derived cytokinins (growth factors) that work through Obagi's Prosome Delivery System to penetrate deep into the skin during its natural overnight repair window. Kinetin has been shown to reduce signs of photoaging by promoting cell turnover without irritation, while zeatin accelerates cell division. Together in this night cream, they target fine lines, roughness, and uneven texture during the 12-hour overnight repair cycle. | Not yet assessed |
| Ceramides NP, AP, EOP | A trio of skin-identical ceramides that work alongside cholesterol and phytosphingosine to rebuild the lipid matrix of the skin barrier overnight. In this formula, the ceramide complex compensates for the barrier lipids naturally depleted by daytime UV exposure and aging — reinforcing the structural integrity that the kinetin-zeatin complex is working to rejuvenate. | Established mechanism for Dryness · established mechanism |
| Palmitoyl Tripeptide-5 | A collagen-stimulating peptide that mimics the body's own thrombospondin-1 signaling to activate TGF-beta, a key trigger for new collagen synthesis. In this overnight formula, it supports the kinetin-driven cell renewal process by encouraging the structural protein production that keeps skin firm and resilient. | Not yet assessed |
| Sodium Hyaluronate | A low-molecular-weight form of hyaluronic acid that penetrates more deeply than its larger counterpart, drawing moisture into the mid-layers of the skin during overnight use. Works in concert with the saccharide isomerate and glycerin in this formula to create a multi-depth hydration system. | Plausible mechanism for Dullness |
| Ergothioneine | A rare amino acid antioxidant found in mushrooms that protects skin cells from oxidative stress at the mitochondrial level. In this night cream, it provides antioxidant defense during the overnight repair window, helping prevent the cumulative oxidative damage that accelerates visible aging. | Not yet assessed |

Make this the final step in your evening skincare routine, after cleansing and any treatment serums. The cream's rich texture creates an occlusive layer that locks in the preceding products. If using retinol, apply it first and allow full absorption before layering this on top.
Immediate overnight hydration and softening from the first use. Improved skin texture and reduced roughness become noticeable within 2-4 weeks. Clinical trials showed 86% improvement in roughness and 80% reduction in rosacea symptoms over 12 weeks of consistent use.
Kinetin (N6-furfuryladenine) has been studied for its anti-aging properties since the late 1990s. A key study published in the Journal of Investigative Dermatology (1999) by Rattan and Clark demonstrated that kinetin delays the onset of several cellular aging characteristics in human skin fibroblasts, including morphological changes and accumulation of lipofuscin. This work laid the foundation for topical kinetin applications.
A clinical trial published in the Journal of Cosmetic Dermatology (2004) evaluated topical kinetin at 0.1% in a double-blind study and found significant improvements in skin texture, fine wrinkles, and pigmentation after 24 weeks, with notably less irritation than retinol at comparable efficacy levels. The mild side-effect profile made kinetin particularly relevant for patients with rosacea or otherwise reactive skin.
The ceramide complex in this formula — NP, AP, and EOP alongside cholesterol and phytosphingosine — reflects the skin-identical lipid approach validated by research from Imokawa et al. published in the Journal of Investigative Dermatology (1991), which established that ceramide depletion is a primary mechanism in barrier dysfunction. Replenishing these specific ceramide species in their physiological ratio has been shown to restore barrier function more effectively than individual ceramides alone.
Palmitoyl tripeptide-5 has been shown to stimulate collagen production through TGF-beta activation. Research reported in the International Journal of Cosmetic Science (2009) documented its ability to increase type I collagen synthesis in vitro, supporting its inclusion in anti-aging formulations targeting skin firmness.
Skin-care clinicians have noted that kinetin-based products fill an important clinical niche for patients whose skin cannot tolerate standard anti-aging actives. Dermatologists frequently encounter patients — particularly those with rosacea, eczema, or post-procedure sensitivity — who need gentle alternatives to retinoids and chemical exfoliants. The clinical trial data showing rosacea symptom reduction is particularly compelling to dermatologists, as few over-the-counter night creams can demonstrate benefits for this condition. The ceramide complex adds proven barrier repair value that dermatologists consider essential for compromised skin types.
Apply a small amount to clean, dry skin every evening as the final step in your nighttime routine. Gently massage into face, neck, and decolletage. Allow the Prosome delivery system to work overnight — the kinetin and zeatin release gradually over 12 hours. Use consistently every night for best results. Can be layered over retinol or other treatment serums for those who tolerate them.
At $102 for 1.7 oz, this cream is priced in the upper range for night moisturizers, but the formulation complexity justifies the premium more than many products at this price point. The combination of kinetin-zeatin technology, a Prosome sustained-release delivery system, a three-ceramide barrier complex, peptides, and ergothioneine represents genuine formulation investment. The clinical trial data adds value that most competitors at this price cannot demonstrate. With discontinuation, availability is becoming an issue.
This night cream is specifically designed for people with sensitive, rosacea-prone, or reactive skin who want anti-aging benefits without the irritation of retinoids and acids. It is ideal for anyone who has tried and failed to tolerate conventional anti-aging products but still wants evidence-based ingredients working overnight.
Those with oily skin may find the emollient base too rich for nightly use. Anyone looking for dramatic, rapid results should consider retinoid-based options instead — kinetin is gentler but slower-acting. Budget-conscious shoppers should note this is a premium product, and those who want guaranteed long-term availability should consider in-production alternatives.

The Gentle Rejuvenation line was Obagi's answer to a real clinical gap: patients who needed anti-aging intervention but whose skin — whether due to rosacea, sensitivity, or prior irritant overuse — could not tolerate retinoids, AHAs, or other conventional aging treatments. Kinetin, a plant growth factor originally studied for its anti-aging properties in the early 2000s, offered a gentler alternative. Though the product has since been discontinued, it remains sought after by patients who found it uniquely compatible with reactive skin.
Obagi Medical was founded in 1988 by board-certified dermatologist Dr. Zein Obagi, a pioneer in skin health restoration. The brand is widely distributed through dermatologist offices and medical spas, with decades of clinical use backing its prescription-grade and OTC product lines.
Plant growth factors in skincare work the same way as human growth factors.
Kinetin and zeatin are cytokinins — plant hormones that regulate cell division in plants. In human skin, they do not function as true growth factors but instead act as antioxidants and mild cell-turnover promoters. The mechanism is different, but the clinical outcomes (reduced roughness, improved texture) are documented.
Discontinued products are no longer effective or safe.
Discontinuation reflects business decisions, not safety concerns. Remaining stock from authorized retailers is identical to what was sold at launch. The formula is stable within its shelf life and PAO period.
Yes, this product has been discontinued by Obagi. Remaining stock may still be available through authorized retailers and online sellers. Obagi recommends the Hydrate Luxe Moisture-Rich Cream as an alternative, though it does not contain the kinetin-zeatin complex that made this product unique.
Yes — clinical trials specifically documented an 80% reduction in rosacea symptoms after 12 weeks of use. The fragrance-free, hypoallergenic formula with kinetin and ceramides was designed for reactive skin, making it one of the few anti-aging night creams clinically validated for rosacea-prone skin types.
Obagi's Prosome Delivery System encapsulates the kinetin and zeatin in liposomal carriers that slowly release the active ingredients over approximately 12 hours. This sustained-release approach allows the growth factors to work throughout the overnight repair window rather than delivering everything at once.
Yes, this cream can be layered over retinol treatments. Its ceramide and allantoin content may help buffer retinol irritation. Apply your retinol first, allow it to absorb fully, then apply this cream as the final step. The gentle formula is designed to complement more active treatments.
Kinetin (N6-furfuryladenine) is a plant-derived cytokinin that has been studied for anti-aging benefits in human skin. Research shows it can reduce signs of photoaging — roughness, fine lines, and uneven pigmentation — without the irritation associated with retinoids. In this formula, it is paired with zeatin, another cytokinin, for enhanced effects.
