01 · We Are CULGenesis

A biological platform closing the Genomic Repair Gap.

Sunscreen and barrier care have protected the surface of the skin for fifty years. But environmental exposure has changed faster than topical protection can compensate — and the genomic damage that drives aging, inflammation, and disease accumulates underneath.

CULGenesis is the next layer.

Our patented small molecules are designed to preserve effective lesion-recognition capacity during the extended post-exposure period — supporting the skin's endogenous CUL4-regulated NER machinery as it identifies and resolves persistent UV photolesions. Protection becomes repair. Repair becomes resilience.

Built on Cornell-origin science. Our composition-of-matter intellectual property is exclusively licensed from Cornell University.

// Three Pillars

What we're building.

▲ Topical · 2027

From Protection to Repair

The first topical products launch in 2027 — generating high-margin revenue from day one, proving the science in market, and funding everything that follows.

▲ Pipeline · 2028+

Beyond the Skin

Skin is the initial program. The same regulatory biology may extend to other epithelial interfaces — a longer-range platform hypothesis we'll validate as data accumulates.

▲ IP · Cornell

Patented Composition-of-Matter

Exclusively licensed from Cornell University. Foundational research established the CUL4A regulatory role in UV-damage response; the licensed chemistry is the proprietary CULGenesis advance.

▲ Design Commitment

Built for the full spectrum of human skin.

UV-associated DNA lesions occur across skin tones, and visible burn is not a universal indicator of underlying damage. Pigmentation also shapes the kinetics of post-exposure lesion formation. CULGenesis intends to validate performance across objective melanin levels and diverse phototypes — not as a marketing claim, but as a development principle baked into study design.

02 · The Dark Repair Gap

The sun sets before the damage does.

Sun exposure activates melanin chemiexcitation — a slow chemical reaction that can continue generating potentially mutagenic DNA lesions for hours after the last photon arrives. At the same time, lesion-recognition proteins are subject to tightly timed turnover. This creates the Dark Repair Gap: a potential mismatch between lesion burden and available repair capacity.

Protection addresses the moment of exposure.
Repair must operate on the window that follows.

▲ A Complementary Layer

Conventional photoprotection is designed for the moment of exposure — filtering radiation as it arrives. Chemiexcitation operates on a different timescale: lesion formation can continue past sunset. CULGenesis is designed as the complementary post-exposure layer — supporting endogenous repair after the protection layer has done its work.

◆ Mechanism · The Kinetic Mismatch

Lesion creation can outlast the recognition window.

Nucleotide Excision Repair (NER) removes UV photoproducts and a range of bulky, helix-distorting chemical lesions. Damage detection involves the CRL4-DDB2 ubiquitin ligase and XPC recognition complex; the sequence requires orderly handoff.

Delayed lesions may continue emerging while these early recognition proteins undergo tightly timed turnover — creating a potential mismatch between lesion burden and available repair capacity.

Over years, unrepaired damage may accumulate into a backlog of genomic injury — associated with premature aging, immune dysregulation, and elevated skin-cancer risk.

// The Dark Repair Gap Delayed lesions may remain while early recognition capacity is contracting
● CONCEPTUAL MODEL
▲ Platform Thesis CULGenesis is designed to preserve effective lesion-recognition capacity through the extended post-exposure period — supporting the cell's native repair sequence without disabling the coordinated handoff required for complete NER.
▲ Evidence Status Conceptual model informed by published biology. Compound-specific kinetics and study details available under confidentiality.
// Why Now

The science is published.
The category is open.

Chemiexcitation, CUL4-regulated NER, and the kinetics of damage recognition are now established in peer-reviewed literature. The differentiated opportunity: a small-molecule layer designed for what follows exposure — complementary to existing photoprotection.

▲ The tipping point
03 · The Platform

Mechanism-defined.
Patented. Validated.

Many cosmetic ingredients are selected primarily for phenotype-level benefits. CULGenesis begins with a defined molecular target, measurable pathway engagement, and composition-of-matter chemistry — the foundation for defensible claims, fortified IP, and a credible development program.

NER is the repair engine. CUL4A is the regulatory checkpoint — the scaffold that helps govern timing, availability, and handoff of early lesion-recognition proteins. Our patented small molecules are designed to tune that checkpoint — supporting endogenous repair capacity through the post-exposure window without disrupting the orderly handoff NER completion requires.

// 01Defensible Claims
// 02Fortified IP
// 03Platform Extension
01

The regulator, not the engine

NER is the body's DNA repair engine. CUL4A is the molecular governor — the regulatory scaffold of the CRL4-DDB2 ubiquitin ligase complex that determines how long lesion-recognition capacity remains available. We modulate the governor, not the engine.

02

Tune the regulatory checkpoint

Our actives are designed to support repair-recognition capacity through the post-exposure period — when chemiexcitation may continue seeding potentially mutagenic lesions after exposure ends — without disrupting the orderly handoff that NER completion requires.

▲ Technical · CULGenesis compounds are designed to modulate CUL4-dependent regulation of early lesion-recognition machinery — including the DDB2–XPC axis involved in global-genome NER.

03

Two Nobel-recognized domains

The mechanism sits at the convergence of ubiquitin-mediated regulation (2004) and nucleotide excision repair (2015) — published in peer-reviewed literature.

04

Cosmetic regulatory framework

The initial topical program is being developed for commercialization within the US cosmetic regulatory framework — including applicable MoCRA requirements. Therapeutic applications would follow the corresponding drug-development requirements.

04 · Where We Sit

A differentiated upstream layer.

SPF filters initiating radiation. Senolytics address senescent cells once they form. NAD+ boosters support cellular energetics. CULGenesis is designed to operate further upstream — supporting endogenous repair of the genomic damage that precedes downstream pathology. Designed as a complementary layer, not a replacement for existing interventions.

06 · Roadmap · Skin First

One regulatory insight. A platform beginning with skin.

The initial program is dermatologic — a topical AM/PM system addressing the post-exposure repair window. The same CUL4-regulated biology may extend to other epithelial interfaces over time, but those longer-range opportunities remain platform hypotheses we will validate as data accumulates.

// Two Products · One Mechanism

Aligned to the kinetic biology.

The portfolio is designed to mirror the mechanism. Morning supports recognition capacity ahead of exposure; evening supports the regulatory checkpoint through the post-exposure window in which chemiexcitation may continue producing potentially mutagenic lesions. An AM/PM ritual aligned to the kinetic biology of DNA damage.

AM Pre-Exposure Priming

Solar Prime

Primes the CRL4-DDB2 recognition complex before exposure. Sets repair capacity for the day ahead.

▲ Morning Application

Walk into the day prepared. Repair-recognition capacity primed for the exposure window ahead.

PM Post-Exposure Sustaining

Signal Mist

Sustains the regulatory checkpoint through the dark-CPD window. Extends recognition through the hours when chemiexcitation continues to seed lesions.

▲ Evening Application

The sun has set. The lesion field has not. Let the cell finish what exposure began.

▲ Why this matters Conventional photoprotection is designed for the moment of exposure. Chemiexcitation extends the lesion timeline past it. CULGenesis introduces a product architecture aligned to the full temporal arc of DNA damage — complementary to existing protection.

09 · Investor FAQ

Questions diligence will ask.

Pre-empted, not deflected. Detailed answers in the deck — these are the lines.

// 01 Why a platform, not a single product?

CUL4-regulated NER biology is the core mechanism — initially developed for skin. The same regulatory insight may extend to other epithelial tissues where CUL4-dependent repair biology is relevant, but those are platform hypotheses pending validation. Initial program: topical. Longer-range opportunities follow data. The same composition-of-matter IP underwrites the family.

// 02 What's the regulatory risk?

The initial topical program is being developed for commercialization within the US cosmetic regulatory framework, including applicable MoCRA requirements. Product claims and intended use are being shaped with regulatory counsel to remain appropriate to that framework. Therapeutic applications (ingestible or inhaled) would follow the corresponding drug-development requirements — a long-range opportunity, not a near-term claim.

// 03 How defensible is the IP beyond the licensed molecule?

Composition-of-matter on the lead chemistry, exclusively licensed from Cornell. Mechanism patents around CUL4A-binding chemistry provide a second layer of protection. Mechanism-defined chemistry supports rational development of next-generation compounds against the characterized regulatory target. Full patent numbers and license scope available under confidentiality.

// 04 What's the moat after the first SKU?

Subsequent topical formulations extend the dermatologic franchise — same mechanism, different formulations, mechanism-protected IP. Longer-range opportunities in other epithelial interfaces remain platform hypotheses pending validation. The launch generates revenue and brand recognition while platform development continues.

// 05 How does this compare to other DNA-repair / longevity companies?

Most operate downstream of damage — senolytics address senescent cells once they form; NAD+ boosters support cellular energetics. CULGenesis is a differentiated small-molecule platform positioned upstream, supporting endogenous repair capacity at the genomic-damage event itself. Same Hallmarks-of-Aging map. Different intervention point. Detailed cascade comparison in Section 04.

// 06 Why this category, why now? What about chemiexcitation?

In 2015, Premi et al. (Brash lab, Yale) demonstrated that melanin chemiexcitation can continue generating CPD-class DNA lesions for hours after UV exposure ends. The category implication: photoprotection addresses the moment of exposure; the lesion timeline can extend beyond it.

CULGenesis is developing a differentiated small-molecule approach for what follows exposure — designed to support endogenous CUL4-regulated NER capacity rather than relying solely on radiation filtering or antioxidant defense. The portfolio architecture (Solar Prime AM / Signal Mist PM) is aligned to that temporal biology.

We position this as a complementary category: Post-Exposure DNA Repair. Sunscreen reduces initiating radiation. CULGenesis supports the cell's capacity to resolve lesions afterward.
