1.🔬The Blue Bottle Betrayal

So Biotherm quietly tweaked their cult-favorite Life Plankton Essence. No fanfare. No announcement. Just a new label and a watery consistency that has loyalists fuming.

The real tea? The old formula felt like silk sliding across your face. The new one? More like fancy tap water that evaporates before your fingers finish patting.

2.💧What Actually Changed

It’s still a “treatment lotion” — $55 for 5.1 oz. The claim is the same: 200x more Life Plankton extract than their original formula. But the texture is thinner. Way thinner.

1

Viscosity shift

Gone is the almost-gel slip. Now it runs off your palms if you’re not fast.

2

Absorption speed

Drinks into skin in 8 seconds flat — but so does water, you know?

3

Scent change

Still that faint, clean plankton smell, but somehow more… diluted.

3.⚖️What’s Actually Inside

Same hero ingredient — Vitreoscilla filiformis ferment (fancy talk for thermal plankton grown in French springs). But the new formula feels like they cranked up the water content and dialed back the thickeners. Here’s the breakdown:

  • Life Plankton Extract: Microbiome balancer — calms redness in 3 days, not 3 weeks
  • Glycerin: The hydrator — but lower on the list now, so less humectant power
  • Zinc Gluconate: Oil control — random in an essence, but helps if you’re shiny
  • Copper/Lysine: Wound healing — makes it decent for post-extraction nights

4.👃The Sink Test

First pump: ran straight through my fingers onto the bathroom counter. Texture is watery-slick, like a thin toner. Takes 3 layers to feel like the old one layer did.

Week two surprise: fewer breakouts. The lighter formula didn’t clog my combo skin like the original sometimes did. But my dry patches? Pissed. Absolutely parched by noon.

💡

One Thing: Press 3-4 drops into damp skin right out of the shower. Let it sit 30 seconds before anything else. This is not a pat-and-go essence anymore.

5.📊The Verdict Grid

Measurable wins: less redness around my nose, fewer tiny bumps on my forehead. But my cheeks feel tighter by 2 PM unless I layer a thick moisturizer after. Trade-off city.

Worth it?
Only if you snag the travel size first. The full bottle is a gamble now.
