Ah, the age-old quest for the fountain of youth, or in this case, the perfect anti-aging serum. Isn’t it just daunting how many of them there are? But hey, I’m here to make your quest easier, my skincare-loving friend. Let’s journey into the depths of the Biotherm Life Plankton Elixir Anti-Aging Serum. In my weeks using this serum, I’ve grown to know it pretty well, and I’m excited to share my thoughts, personal experiences, and some inside scoop on the formula.

You see, the little wrinkles creeping up around my eyes and the ever-increasing dryness of my skin have been my recent battles. And ladies, we all know how annoying these can be. Enter the Life Plankton Elixir Anti-Aging Serum from Biotherm – a product that caught my eye and my hope.

Being a die-hard fan of Biotherm, I had high expectations. Most of their products I’ve used before have left me satisfied, and I was genuinely excited to see what this serum would bring. So sit back, relax, and let’s dive into this in-depth review. I hope you find it helpful.

Oh, and just to throw it out there, this isn’t a paid or sponsored review. I’m just a skincare enthusiast who loves sharing my honest thoughts and experiences. No strings attached!


Biotherm’s Life Plankton Elixir is an anti-aging serum that does more than just fight wrinkles. It’s an elixir for dehydrated, dull skin that yearns for a healthy glow. Though primarily intended for your face, you can extend its goodness to your neck and décolleté as well.

As an advocate for animal rights, I’m thrilled to say this product is cruelty-free. Plus, with a 50ml bottle at your disposal, you’re looking at a couple of months of regular use. It’s suitable for all skin types, but if your skin is very sensitive, you might want to do a patch test first because it does contain alcohol denat.

Biotherm, the brain behind this product, is a brand that’s been on my radar for a while. Their products often come recommended by friends, and I must say, their reputation is well deserved.

A look at the ingredients list of Life Plankton Elixir reveals some heavy hitters like Vitamin C, hyaluronic acid, and the signature Life Plankton. But let’s not get ahead of ourselves, we’ll dive deeper into the ingredients a little later.

Did The Life Plankton Elixir Anti-Aging Serum Work?

Believe me when I say I’ve trudged the murky waters of anti-aging serums more times than I can count. I’ve battled with ineffective formulas, broken promises, and the all-too-common heartache of a skincare routine that yields no results. When I first got my hands on the Life Plankton Elixir, I’ll admit, my past experiences with other serums had me a tad skeptical.

As per the guidelines, I started using the Elixir every day, integrating it into my morning and evening skincare routine. I loved that it wasn’t another complicated step I had to remember – it slipped right in effortlessly, acting as a precursor to my moisturizer. Right from day one, the lightweight texture was a delight to apply, absorbed quickly without leaving a sticky residue, and the fragrance was subtle yet soothing.

Fast forward to a week into using the product, I started seeing changes – subtle at first, but delightfully noticeable. My skin had this radiance, a glow that wasn’t there before. My friends were asking if I had changed my makeup routine, but it was all thanks to the Elixir!

I’m a gal who loves her beach days and unfortunately, that means dealing with the occasional bout of dry skin. But with the Life Plankton Elixir, my skin stayed hydrated and soft despite long hours in the sun. I even noticed that those stubborn little laugh lines around my eyes were looking less prominent, which, let me tell you, is a sight for sore eyes!

Of course, in the world of skincare, nothing is a silver bullet. I did have my hiccups with the Elixir. As someone with a sensitive nose, I found the scent a little overpowering during those first few uses. And let’s not ignore the elephant in the room – the price tag. It’s certainly an investment, which might not suit everyone’s budget.

All that said, reflecting on my journey with the Life Plankton Elixir, it’s like a love letter to my skin. The initial scent and cost issues were small hurdles in what has otherwise been a magnificent race. My skin feels rejuvenated, looks radiant, and those pesky signs of aging? They’re less of a concern now. Overall, I am genuinely delighted and satisfied with my experience.

Using The Life Plankton Elixir Anti-Aging Serum

The first time I held the Life Plankton Elixir in my hands, it felt like I was cradling a gem. I mean, the packaging alone exudes a sense of luxury and quality that had me smiling right out of the box. It felt substantial, well-crafted, the kind of product that you’d be proud to display on your vanity. And let me tell you, it has the looks to match any special occasion gift, birthday, or anniversary.

The initial sensation of applying the serum was an experience in itself. Imagine a feathery touch, lighter than air, gliding effortlessly on the skin, that’s what it felt like. There was an instant sense of nourishment as if my skin was drinking in the goodness from the very first use.

The amount I used was about two pumps, which seemed to hit the sweet spot. It was just enough to cover my face and neck without feeling like I was overdoing it. But hey, you do you, whether you prefer a more generous application or just a dab, it’s all about what makes your skin feel good.

In terms of where it fits in your skincare routine, think of it as the trusty best friend that you always turn to, no matter the situation. After cleansing and toning, but before you apply your moisturizer, the Elixir steps in to amplify your skincare routine. It was like adding an extra layer of hydration and anti-aging goodness to my skin. The why is simple – it aids in better absorption of your subsequent skincare steps while delivering its own potent benefits.

And here’s the thing – I’ve been around the skincare block a few times, tried my fair share of serums and creams. But the way the Life Plankton Elixir fitted into my routine was like it was always meant to be there. Like the final piece of a puzzle, enhancing and supporting, without overpowering my skin or my senses. It felt natural, it felt right, and that made me enjoy it all the more.

Is Biotherm Life Plankton Elixir Worth the Money?

The backbone of any skincare product lies in its ingredients. It’s like baking a cake; the final outcome depends on what you put into it. So let’s break down what’s in the Life Plankton Elixir.

  • Bifida Ferment Lysate: This ingredient is a type of yeast obtained by fermentation. It’s a probiotic ingredient that can have repairing and anti-aging properties on the skin. It works to strengthen the skin’s barrier, protect against environmental stressors, and even out skin tone.
  • Glycerin: A well-known skincare ingredient, glycerin is a humectant that works by drawing moisture from the air into your skin. This hydrates the skin, leaving it soft, supple, and healthy-looking.
  • Alcohol Denat: This is a drying type of alcohol. While it can have short-term benefits by giving products a quick-drying finish and a weightless feel, it might be irritating for those with sensitive skin.
  • Hydroxyethylpiperazine Ethane Sulfonic Acid: A type of amino acid, this ingredient can help balance the pH of the product and is also an exfoliant that helps remove dead skin cells, leaving the skin smoother.
  • Sodium Hyaluronate: This is the salt form of hyaluronic acid and it’s more easily absorbed by the skin. Its powerful hydrating properties help retain skin moisture, reducing the appearance of fine lines and wrinkles.
  • Vitreoscilla Ferment: Also known as Biotherm’s signature Life Plankton, Vitreoscilla Ferment is derived from thermal plankton, which is rich in vitamins, minerals, and amino acids. It’s known for its skin-soothing and strengthening properties.
  • Ascorbyl Glucoside: This is a stable form of Vitamin C, which is a potent antioxidant. It helps to brighten the skin, fight free radicals, and stimulate collagen production, reducing signs of aging.
  • Adenosine: Known for its skin-soothing and restoring properties, adenosine is also believed to be a cell-communicating ingredient that can support skin repair and renewal processes.
  • Hydrolyzed Hyaluronic Acid: This is a smaller molecule than regular hyaluronic acid, meaning it can penetrate the skin more deeply for more intense hydration. It also has anti-aging properties, helping to reduce fine lines and wrinkles.
  • Tocopherol: Also known as Vitamin E, this ingredient is a strong antioxidant that helps neutralize harmful free radicals, prevents premature skin aging, and maintains skin’s moisture balance.
  • Hyaluronic Acid: This powerful hydrator can hold up to 1,000 times its weight in water, keeping your skin plump and hydrated, thereby reducing the appearance of fine lines and wrinkles.

In conclusion, I’m truly impressed by the thoughtfulness and effectiveness of the ingredients Biotherm packed into this serum. They’ve got some great skincare powerhouses in there!

Final Word

There are countless anti-aging serums out there, but the Biotherm Life Plankton Elixir has been one I was always curious to try. After a month of use, I’d confidently give it a solid 8.5/10.

Why the high rating, you ask? The noticeable results, excellent formulation, and Biotherm’s reputation are hard to ignore.

Sure, I’ve tried many products in the past, but this serum stands out among the crowd. I genuinely enjoyed using it, and the results left me happy. If you’re a Speaking Skincare reader looking for a solid anti-aging serum, I’d say give this one a shot!

But before you jump on the bandwagon, remember that skincare is personal. The alcohol denat might not sit well with everyone, and the rich texture might be a bit much for some. But if you’re willing to take the plunge, you can find Biotherm’s Life Plankton Elixir on their website and at other online stores.

And with that, we wrap up this review. Stay radiant!
