Biologi Skincare Review: Luminosity, Rejuvenation, Hydration

This is a sponsored post.

Biologi are a brand that’s doing something I haven’t seen before in consumer skincare – they sell single ingredient, undiluted, “100% active” whole plant extracts as ready-to-use skincare products, with no extra potential irritants like fragrances, preservatives or emulsifiers. Plant extracts are often the “hero” active ingredients in skincare products, but in general you’ll find them at really low concentrations (2% or below). While this means that you can cram more actives into the one product, it also means that the final product is less potent, and a lot of the time the benefits come from the first few standard ingredients instead of the plant extracts.

Biologi was started by Ross Macdougald, a chemist with 30 year’ experience as a product development chemist working with many multi-national companies developing cosmetic formulations and active ingredients. Annoyed at how the low concentrations meant that the natural ingredients weren’t really getting a chance to shine, Biologi sells certified organic plant actives at 100% concentration, extracted using a special method to keep the extract as unaltered from the natural version in the plant as possible. The entire production process is controlled by the one company, so the products are traceable from plant to bottle.

Some natural ingredients can’t really be used at high concentrations since they can cause reactions, but the ones from Biologi are fine to use even if you have sensitive skin, as long as you introduce them slowly. They currently have three products, which Biologi recommend as all-in-one moisturiser, toner, primer, eye cream and anti-aging product (they recommend that you have an additional cleanser, exfoliator and sunscreen). The three products are:

• Bd Luminosity – 100% Davidson Plum
• Bk Rejuvenation – 100% Kakadu Plum
• Bf Hydration – 100% Finger Lime

Bd Luminosity Face Serum ($97.95 for 30 mL) contains 100% Davidson Plum extract. Some of the key components of the extract are phenolic acid, tartaric acid, anthocyanin and quercetin, which are supposed to help skin strength, hydration, natural skin glow and photosensitivity, and creates a protection barrier against environmental factors. It’s recommended for rejuvenation, anti-aging and acne prone skin.

Bk Rejuvenation Eye Serum ($79.95 for 15 mL) is 100% Kakadu Plum extract, which has gallic acid and ellagic acid along with a whopping 40% vitamin C, in its unaltered plant-sourced form. I didn’t quite trust that the high vitamin C wasn’t a typo, but Biologi kindly provided me with their HPLC analytical data (performed by Southern Cross University) and yeah, 40% is right. As you’d expect from a high vitamin C product, it claims to increase collagen production, elasticity and skin tone, and protect your skin from environmental damage. Since the pure plant extract is used, the vitamin C should be stabilised from oxidation by the components that would normally keep it stable inside the plant.

Bf Hydration Body Serum ($64.95 for 50 mL) has 100% Finger Lime extract, which has tryptophan, ferulic acid and 10% vitamin C (again, verified by Southern Cross University). It’s intended to increase moisture, protect from environmental damage, boost collagen, elasticity and even out skin tone. You can use this on your face as well if you like, but Biologi recommend that you use it in conjunction with another Biologi product.

All three products are very runny serums. Bk Rejuvenation takes the longest to sink in, but once they’ve had time to sink in all three leave a similar weightless but slightly sticky film on the skin. Bf Hydration smells a bit like lemonade, while the other two smell slightly sweet (and all three taste sweet, if you’re tempted to lick them).

The lack of preservatives worried me at first, but Ross reassured me that they’d been stability tested to have a 2 year shelf life, and the airless pump bottles prevent the entrance of any microbes. The pump bottles are really gorgeous as well.

After a week of using Rejuvenation and Luminosity on my face I had noticeable fading of some hyperpigmentation of some chin acne that had been lingering, and my skin felt beautifully hydrated the whole time. Hydration also worked fantastically on my legs, which are usually very difficult to keep smooth and hydrated, but it completely got rid of my scaly winter skin – and they stayed smooth for a week after I stopped using it too.

They are a bit on the pricey side if you’re considering them as a single skincare product, but if you consider the percentages of actives compared to products that contain the same actives they’re really good value – for example, Biologi Bk is $79.95 for 15 mL with pure (100%) active, but if you diluted it to 2% like in a standard product it would translate to $1.60 for 15 mL.

If you intend to use them as all-in-one products they’re pretty good value, and compared to other luxe natural, certified organic products they’re pretty similarly priced (and of course, actually better value if you consider the percentage of actives as I mentioned above).

Biologi can be purchased at the Biologi webstore.
