📊 Comedogenicity

2/5

🛡️ Safety rating

Safety tier is a starting heuristic from regulatory status and comedogenic rating, not a dermatological verdict — see our Terms for the full disclaimer. Research confidence reflects how many real cited studies back this ingredient, not the strength of their findings.

🌍 Regulatory Status

💧 Skin Type Compatibility

Derived from this ingredient’s irritancy potential and comedogenicity rating against the needs of each skin type — e.g. oily and acne-prone skin are marked down for pore-clogging ingredients, sensitive skin for irritants. A starting heuristic, not a dermatological verdict.

📚 Research & Evidence

🔬 The Science

Linum usitatissimum seed oil contains significant amounts of polyunsaturated fatty acids (PUFAs), with alpha-linolenic acid (ALA) being particularly abundant. The body can partially convert ALA into omega-3 fatty acids like docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), though this conversion is limited. The seed itself is nonabsorbable fiber that has historically been used as a laxative and applied topically to treat various skin conditions. Beyond its fatty acid content, flaxseed contains other nutritionally significant compounds: #1: The seeds are rich in protein and fiber depending on growing conditions and seed color (yellow-seeded varieties tend toward higher oil content under normal conditions, while brown-seeded varieties accumulate more fiber and protein under water stress, according to Plants (Basel) 2023).

#2: Flaxseed contains lignans, specifically secoisolariciresinol diglucoside, a secondary metabolite whose concentration varies by seed type and environmental conditions. #3: The seeds contain mucilage, a gel-forming substance whose content also varies by variety and growing conditions. Regarding safety, flaxseed is generally well tolerated in adults, with the 2006 peer-reviewed source noting only occasional allergic skin reactions as a concern. However, that same source emphasizes that very limited data exist on safety and efficacy in nursing mothers or infants, and notes that because dietary supplements don’t require extensive pre-marketing FDA approval before sale, differences often exist between labeled and actual ingredient amounts across different products.
