Evidence-Based Approach

Our Methodology

Transparency is core to what we do. Here is exactly how LuxSense analyzes and scores cosmetic ingredients.

Our Data Sources

EU CosIng Database

The European Commission's official Cosmetic Ingredient database contains over 36,000 entries with regulatory status, restrictions, and authorized functions.

This is the primary authority for cosmetic ingredient regulation in the EU and provides the foundation for our safety assessments.

PubChem (U.S. NIH)

PubChem is the world's largest open chemistry database, maintained by the U.S. National Institutes of Health. It provides detailed safety, toxicity, and hazard data.

We use PubChem's GHS hazard classifications and toxicity data to supplement EU regulatory information.

Open Beauty Facts

A community-driven, open-source database of cosmetic products from around the world, providing real product data and ingredient lists.

Licensed under ODbL, this helps us match barcodes to products and cross-reference ingredient lists.

Scoring System

Every ingredient receives a safety score from 0 to 100. Here is what the ranges mean.

90+

Excellent

Well-studied ingredient with strong safety profile. No significant concerns identified in regulatory or scientific data.

70+

Good

Generally safe with minor or conditional concerns. May have usage restrictions at high concentrations.

50+

Moderate

Some concerns exist. May be an irritant for sensitive skin, have environmental concerns, or be subject to regulatory restrictions.

30+

Caution

Notable safety concerns. May be a known irritant, allergen, or have significant regulatory restrictions. Worth investigating further.

<30

Avoid

Serious safety concerns. May be banned or heavily restricted in the EU, known to be toxic, or have strong scientific evidence of harm.

What We Analyze

Regulatory Status

Is the ingredient authorized, restricted, or banned in the EU? What are the maximum permitted concentrations? We check against official CosIng data.

Irritant Risk

Based on GHS hazard classifications from PubChem and known allergen data, we assess the likelihood of skin irritation or sensitization.

Comedogenic Risk

We flag ingredients known to clog pores based on established comedogenicity research, helping those with acne-prone skin make better choices.

Environmental Impact

We assess environmental concerns including aquatic toxicity, biodegradability, and whether the ingredient is flagged for environmental harm.

Our Commitment to Transparency

No Fear-Mongering

We do not sensationalize. If an ingredient is safe according to regulatory data, we say so clearly, even if it has a scary-sounding chemical name.

Evidence-Based

Every score is derived from regulatory databases and published scientific data. We do not rely on anecdotal claims, influencer opinions, or marketing materials.

Sources Cited

In the app, every ingredient links back to its source data. You can verify our assessments against the original CosIng and PubChem entries yourself.

Public commitments

Five things LuxSense will not do.

The clearest way to describe a methodology is sometimes by what it excludes. These are explicit commitments, not aspirations.

No affiliate links, no commerce kickbacks.

LuxSense does not sell products, link to retail with revenue-bearing affiliate codes, or accept payment for ingredient or product placement. Our scoring is independent of any commercial relationship with brands or retailers.

No brand call-outs by name.

We score ingredients against regulatory and scientific evidence, not products against brands. You will never see a "this brand is dangerous" framing on LuxSense. Scoring stays at the ingredient level, where the science actually lives.

No "no data = safe" defaults.

When the published toxicology or regulatory data on an ingredient is insufficient, we flag it as insufficient data, not as "likely safe" by default. Insufficient evidence is its own category, and we say so.

No alarmist vocabulary.

Words like toxic, dirty, chemical-free and free from obscure more than they reveal. LuxSense uses regulator-grounded language: Annex II prohibited, Annex III restricted at X%, SCCS opinion pending. Every score links to its source.

No private methodology.

Every input to a score is published. The data sources are public. The scoring rubric is on this page. When regulators or scientific committees update their positions, LuxSense's scores update with them, and we say what changed.

Important Disclaimer

LuxSense provides informational ingredient analysis only. It is not medical, dermatological, or health advice. Safety scores are mathematical outputs of our algorithm and are not endorsed or certified by any regulatory body.

Ingredient lists extracted from photos via AI vision (OCR) may be incomplete, inaccurate, or vary between scans depending on photo quality and label legibility. Our algorithm does not consider ingredient concentrations, formulation context, pH, individual skin factors, or interactions between ingredients.

Always read the physical product label. If you have allergies, skin conditions, or health concerns, consult a qualified healthcare professional before using any cosmetic product.
