Formulate a skincare product these days and you're likely looking at a familiar lineup: hyaluronic acid for hydration, niacinamide for brightening, throw in a peptide or two. They work. But they each do one thing, maybe two if you're generous.
The issue isn't that these ingredients fail. It's that relying on them to build minimalist, "protect and repair" skincare products often means stacking more actives than the category originally intended. The result feels counterintuitive: formulas claiming simplicity that require multiple functional ingredients to hit all the expected claims.
In a recent webinar, Covalo and Bitop brought together cosmetic engineer Marina Cardia Jardim (founder of Tupi Beleza) and Disha Patel, Senior Sales & Business Development Manager at bitop, to discuss a different approach. The focus: two naturally derived ingredients called Ectoin® natural and Glycoin® natural, marketed as "extremolites" designed to collapse multiple benefits into one or two actives. The conversation touched on real formulation challenges and regulatory considerations worth unpacking.
Modern skin isn't dealing with one acute problem, it's dealing with accumulated exposure. Blue light, air pollution, and rapid environmental shifts wear down the skin barrier continuously, pushing it toward oxidative stress and inflammation.
As Marina Jardim put it during the session, this has changed what "performance" means in a formula:
"Barrier repair isn't a trend anymore. It's a must for performance in skincare."
That shift matters commercially, too. Consumers more attuned to microbiome health and environmental exposure since the pandemic are actively seeking out prevention claims, not just repair claims after damage is already visible. The result is a growing expectation that a single product should protect, repair, and support long-term skin resilience without a ten-step routine to get there.
It's easy to be skeptical of any ingredient marketed as "does everything." But Disha Patel drew a sharp distinction between genuinely multifunctional actives and the popular ingredients formulators default to.
"You cannot expect niacinamide to have any kind of anti-inflammatory benefits... nor can you expect hyaluronic acid to reduce the redness or irritation on your skin."
That's not a knock on those ingredients. They're effective at what they do. The point is narrower than most people assume: a hero ingredient with one or two functions still requires a formulator to stack additional actives to cover inflammation, barrier repair, energy metabolism, or pigmentation. Multifunctionality, done properly, isn't a buzzword. It's a way to replace three ingredients with one without losing efficacy on any single benefit.
Ectoin was discovered in 1985 by Professor Dr. Galinski and is produced by halophilic bacteria (Halomonas elongata) that survive extreme salinity and heat, which is exactly why the molecule itself is so heat and cold-stable. Bitop was the first company to bring it commercially into cosmetics.
Its mechanism is what gives it such a broad claim set: ectoin forms "ectoin-hydro complexes," effectively acting like a magnet that pulls water molecules onto the lipid bilayer, stabilizing the cell membrane and improving fluidity. That stabilization is what drives its documented claims:
"It's kind of a second skin... working to protect and prevent your skin from any damage that comes your way." — Disha Patel
For formulators, the more immediately useful detail may be how forgiving ectoin is to work with. It has a broad pH range, is water-soluble, tolerates boiling temperatures without degrading, and has no strict formulation order. Add it before or after emulsification, at 70°C or 100°C, alongside retinoids, vitamin C, phospholipids, or ceramides, with no compatibility issues.
"It's one of a kind... we call it the formulators' darling, because there are actually no guidelines to follow when you're using ectoin."
That's the specific gap Ectoin® natural and Glycoin® natural are positioned to fill.
If ectoin is about stabilization, Glycoin® natural is about metabolism. Chemically a glycerol glucoside, it's biotechnologically inspired by Myrothamnus flabellifolia, a "resurrection plant" native to African deserts that can appear completely dead after prolonged drought, then fully re-green within 24 hours of rehydration. That resilience comes from its natural production of glycerol glucoside, which Bitop replicates through an enzymatic, sustainable process.
Once on skin, glycoin boosts cellular ATP production, functioning as fuel for skin cell metabolism, which is why it's referred to internally as the "cell energizer." Its differentiated claims include:
Ectoin and glycoin share several overlapping claims: anti-aging, blue light protection, and brightening. But their standout benefits are distinct enough that Disha Patel and Marina Jardim described them as complementary rather than interchangeable, calling glycoin "the brother of ectoin."
During the webinar, Marina Jardim started essentially formulating out loud, checking her own logic against Patel's:
Disha Patel's take on combining them was blunt:
"You don't need another active — unless it's for marketing. As far as efficacy is concerned, they both are enough to complete the claims."
Prevention is trending as a claim category, but formulators are often unsure how to substantiate it. Disha Patel's answer was more concrete than the industry chatter usually is: it depends entirely on what you're preventing (sun damage, barrier disruption, pigmentation) and the format you're using. At 1 to 2% concentration, ectoin has clinical data supporting anti-inflammation and skin barrier repair claims specifically framed as prevention.
One clarification worth flagging for regulatory teams: Ectoin® natural and Glycoin® natural are cosmetic-grade actives. Bitop also produces med-ectoine, a pharmaceutical/medical-device-grade version used where a finished product needs to be registered as a drug or OTC product. Regulations here vary significantly by country. What's cosmetic in one market may require medical registration in another.
The broader argument from this session isn't that ectoin and glycoin are miracle molecules. It's that "next generation" shouldn't just mean new. It should mean ingredients engineered to do more per molecule, so formulators can build genuinely minimalist products without quietly compromising on efficacy.
Stressed, inflamed skin becomes the baseline condition formulators are designing against, not the exception. Backbone actives like these may end up doing more to simplify formulation than any amount of ingredient stacking ever could.
