Formulation Evaluation Lead Since 2021
Overview
A disciplined technical approach ensures our skincare formulation catalog offers only verified compounds with physiological bioavailability and stable packaging barriers.
Professional Background
Irina Petrova joined Dermai in 2021 to oversee product development, compound curation, and regulatory compliance. Her background combines cosmetic chemistry analysis with clinical formulation logistics across European and North American dermatological standards.
Operational Offer
Curation of active creams and serums (33–125 USD per sealed unit) and facial, body, and hair care cosmetic regimens (28–150 USD per sealed unit). Encompasses plant cellulose capsules, dietary softgels, compressed mineral tablets, micronized powders, and topical emulsions.
Quotation Mechanism
Every entry represents the baseline cost for one individual package unit. Quotes depend directly on manufacturer brand, volume or capsule count, INCI active ingredient purity, release format (airless pump, amber dropper, blister-packed softgel), fulfillment from our Portland facility, and volume tier structures.
Corporate Verification
Backed by active Florida corporate entity registration and formal cosmetic trade association membership. All outbound shipments are audited against lot retention records before dispatch from 224 Southwest 1st Avenue in Portland, Oregon.
Methodology
Every formula reviewed by Irina Petrova must survive a five-stage filtration rubric before being authorized for catalog publication.
Criterion 1 • Active Purity
Raw ingredients must provide third-party chromatography verifying active stereoisomer integrity. Synthetic peptides must achieve ≥98.0% purity; plant-derived lipids such as squalane must demonstrate complete absence of residual pesticide solvents.
Criterion 2 • Physiological pH
Acid-tolerant actives such as topical vitamin C formulations are maintained between pH 3.0 and 3.5. Peptide face serums and barrier repair moisturizers are calibrated to pH 5.2–5.8 to support stratum corneum acid-mantle enzyme activity.
Criterion 3 • Packaging Barrier
We reject transparent flint glass and unsealed open-mouth jars. Actives vulnerable to atmospheric oxidation must be enclosed in airless polypropylene vacuum dispensers or Grade III amber apothecary glass flushed with medical-grade nitrogen.
Criterion 4 • Preservative Safety
Formulas must pass United States Pharmacopeia <51> antimicrobial challenge tests using nature-identical organic acids (sodium levulinate and sodium anisate). Formaldehyde-releasing biocides and parabens are banned outright.
Criterion 5 • Run-Length Modeling
Formulations must carry realistic volumetric run-lengths. Irina Petrova verifies that single package units provide clinically meaningful 30, 60, or 90-day supply spans when applied across specified anatomical zones.
Oversight
Continuous physical batch auditing ensures that clinical aesthetic clinics receive unadulterated cosmetic batch specifications.
Lot Traceability
Every compounding run is assigned an indelible alphanumeric lot code stamped on both the container base and outbound shipping carton. Retained reference vials from every lot are stored in our Portland vault for twenty-four months.
Thermal Vault Monitoring
Our storage warehouse at 224 Southwest 1st Avenue maintains continuous environmental data logging. Temperatures are held at 18°C ± 2°C with automated excursion notifications dispatched to Irina Petrova.
Clinic Protocol Consulting
Irina Petrova conducts formulation audits for aesthetic medical practices, calculating specific volume requirements, transit timelines, and sensitive skin skincare regimen compatibility.
Refusals
Strict formulation boundaries that Irina Petrova enforces across our active skincare catalog.
No Synthetic Fragrance
Fragrance chemicals are the leading cause of cosmetic contact dermatitis. We reject masking agents and volatile citrus essential oils across all creams, serums, and cleansers.
No Inflated Marketing Potencies
We refuse to formulate peptides or exfoliating acids above biological saturation thresholds. Excessive concentrations provoke tissue irritation without increasing therapeutic cellular signaling.
No Opened Return Processing
Safety protocol prohibits restocking unsealed products. Once a seal is severed, micro-contamination risks prevent product re-issuance.
No Telemedicine Prescriptions
Dermai provides physical cosmetic formulations and dietary oral-dermal adjuncts. We do not provide medical diagnoses or schedule telemedicine doctor consults.
