Vaccinium Myrtillus Seed Oil

Vaccinium Myrtillus (bilberry) seed oil is primarily an emollient/occlusive lipid used at low-to-moderate levels in moisturizers and serums, and like most refined plant seed oils it is generally well tolerated. However, botanical oils can still trigger irritation or allergic contact dermatitis in a small subset of highly reactive or eczema-prone patients, particularly if the oil is less-refined or oxidized. Given that nonzero risk but overall low clinical irritancy at typical use levels, a gentle score is most appropriate. Safety Notes: In mass-market leave-on skincare (creams/lotions/serums), Vaccinium Myrtillus (Bilberry) Seed Oil is often used as a minor emollient/antioxidant-support oil at trace-to-low levels (typically ~0.01–0.2%) within blended “berry seed oil” or “antioxidant oil” complexes. Mid-range inclusion in facial oils and richer balms commonly falls around ~0.5–10% as part of a multi-oil lipid phase. The upper end reaches 100% in consumer-available single-ingredient bilberry seed oil products sold as facial/body oils (neat oil); rinse-off products, when it appears, are usually at the low end due to cost and rinse-off deposition limits.
