Best Biologi Products for Mature Skin
3 Biologi picks that actually work on mature skin — ranked by editor rating, not by what the brand pushes hardest. Updated 2026.
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.

8.5/10 · serumBf Restore Face & Body Serum
Biologi's radical proposition: single-plant-extract serums with no added water, no added actives, no emulsifiers — just the plant and a preservative. The Bf serum is 100% Kakadu plum extract, containing the world's highest natural concentration of vitamin C (up to 100x more than oranges), plus gallic acid (anti-inflammatory), ellagic acid (antioxidant), and the full phytochemical matrix of the fruit. The idea is that the whole-plant extract delivers better than isolated actives. The clinical evidence is promising: published studies show 28% reduction in redness after 8 weeks. A genuinely novel approach to botanical skincare — Australian native science, not just marketing.

8.5/10 · serumBk Vitamin C Face & Eye Serum
Biologi's vitamin C hero — single-ingredient Kakadu plum extract (the highest-vitamin-C food known to science) bottled with nothing else. Where Bd is for general luminosity, Bk is for serious vitamin C work and is gentle enough for the eye area. The native Australian Indigenous-fruit story plus the radical-simplicity philosophy is what makes Biologi a niche editorial favorite.

8.4/10 · serumBd Luminosity Face Serum
Biologi's radical pitch: a single-ingredient face serum, harvested from Australian Davidson plum and bottled with nothing else. No water, no preservatives, no surfactants — just the plant extract itself, naturally rich in vitamin C, polyphenols, and amino acids. The Bd version is the brand's brightening-luminosity hero. Sounds gimmicky; the formulation philosophy is genuinely interesting and the result is real.
