Scientific Methodology & Scoring Architecture
Oriva operates on a 4-layer deterministic decision engine. Every recommendation, warning flag, and compatibility score is verifiable, reproducible, and explainable.
The 4-Layer Intelligence System
Cosmetic Chemical Database
Ingredients are indexed with chemical CAS numbers, functional roles (humectant, emollient, occlusive, surfactant), molecular weights, pH stability windows, and comedogenic thresholds. We do not rely on binary "clean vs dirty" marketing gimmicks.
Full Formulation Matrix Analysis
Products are evaluated as complete chemical matrices. An ingredient rated 4 on an outdated raw scale is assessed differently when formulated at 0.5% in a water-based gel versus 20% in an anhydrous ointment.
Skin Fingerprint & Health State
User profiles map sebum excretion rate, stratum corneum barrier health, sensitivity triggers, pregnancy status, active retinoid usage, and Malassezia susceptibility into a multi-dimensional constraint vector.
Deterministic Rule Evaluation
The engine evaluates hard disqualification rules (e.g. retinoids for pregnant users, lipid triggers for fungal acne) followed by soft scoring adjustments (occlusiveness vs ambient humidity, ceramide ratio bonuses).
Specialized Screening Frameworks
Fungal Acne (Malassezia) Protocol
Malassezia yeast consumes lipids with carbon chain lengths between C12 and C24. Oriva screens for all straight-chain fatty acids (lauric, palmitic, stearic, oleic), polysorbates (20, 40, 60, 80), and ester compounds, while validating safe exceptions like sugarcane Squalane and Caprylic/Capric Triglycerides.
Revised Comedogenic Thresholding
Rather than relying on outdated 1970s rabbit ear tests, Oriva weighs ingredient placement in the INCI list, finished texture viscosity (gel, lotion, cream, balm), and sebum-dissolving actives (salicylic acid) to determine true acne safety.
Pregnancy Safety Screening
Flags systemic and topical Vitamin A derivatives (Tretinoin, Retinol, Retinal, Adapalene), hydroquinone, and leave-on salicylic acid >2%, while highlighting dermatologist-approved alternatives (Azelaic Acid 10–15%, L-Ascorbic Acid, Glycolic Acid <10%).
Geo-Climate Adaptation Model
Integrates real-time ambient relative humidity and temperature. In high humidity (>70%), heavy petrolatum occlusives are penalized to prevent follicular congestion; in low humidity (<40%), multi-weight humectant-emollient combos receive score boosts.
