Biologi's serums are unusual: single-plant-extract formulas with no preservatives, no emulsifiers, and no water — just the plant's own liquid, extracted cold. The Bf Bakuchiol + Finger Lime Cucumber Serum is a genuinely novel product. Short shelf life is the honest trade-off.
Strengths
- + Single-ingredient focus
- + No preservatives or fillers
- + Strong native-Australian sourcing
Weaknesses
- − Short shelf life (60-90 days open)
- − Premium pricing
- − Small range
The Biologi Story
Biologi was founded in 2017 in Sydney by Ross Macdougald, a biochemist who'd been researching plant-extraction techniques for Australian native botanicals (finger lime, kakadu plum, native eucalyptus). The brand's proprietary process extracts bioactive compounds from fresh plants as a water-free liquid, preserving compounds that typically degrade in standard formulation. Each product contains exactly one ingredient. Distribution is primarily premium Australian retail and select global spas.

Bg Defence Anti-Pollution Serum
Biologi's signature radical-minimalism. The entire INCI list is four ingredients — but the Eucalyptus Olida (Australian Strawberry Gum) Leaf Extract at 99.8% naturally contains salicylic acid, niacinamide (B3), pantothenic acid (B5), and protocatechuic acid (a potent antioxidant). Cold-pressed, single-source, no synthetic actives needed. The Australian indie brand that's quietly beating Korean essence drops at their own game.
