CALECIM®️’s PTT-6®️ technology takes the spotlight in an article featured in The New York Times exploring regenerative skincare, hair thinning and the science of aging. Can cell-signaling technology really improve how our skin and hair behave?

The article raises an essential point:

“Not every ‘regenerative’ claim has the same evidence behind it.”

Here’s what matters.

1. Is the science plausible?
Yes. Growth factors and other signaling proteins can influence processes involved in skin repair and the environment around hair follicles.

As Dr. Phoebe Jones explains in the article, “we’re trying to improve the biology of the skin itself.”

But a plausible mechanism is only the beginning. Each technology needs evidence of its own.

2. How powerful is the active ingredient?
Its source, concentration and biological activity matter. Simply including exosomes or growth factors does not establish effectiveness.

CALECIM’s PTT-6®️ combines naturally produced growth factors, cytokines, proteins and exosomes derived from proprietary umbilical cord lining stem-cell technology. This complex mixture delivers multiple biological signals, with its activity investigated in laboratory and human studies.

3. What should you look for?
Research showing both how the technology works and what improvements occur in people. Check the formulation tested, study size, results and safety reporting.

Expect gradual improvements in skin quality and healthier hair with decreased shedding.

The promise is compelling. The evidence behind the active ingredient is what gives it credibility.

More than ingredients. PTT-6®️ influences behavior.

Through cell signalling, PTT-6®️ goes beyond what you apply to your skin and scalp. It helps influence how your own cells respond and function.

Cell messaging is already part of the conversation around exosome skincare and haircare.

Here’s how PTT-6®️ is different:

1. A distinctive stem cell source

PTT-6®️ is derived from ethically sourced stem cells, using patented technology. It contains the biological substances these cells release.

1. More than exosomes

Exosomes are only part of the picture. PTT-6®️ also contains growth factors, cytokines and other stem-cell-derived proteins involved in cellular communication.

This naturally produced complex brings a broad combination of biological messengers together. That complexity is central to the PTT-6®️ approach to skin and scalp health.

1. Studied in the laboratory—and in people

Our research investigates what this complex actually does. And includes both in vitro research—showing how cells respond in the laboratory—and in vivo research—assessing results in people. Together, they help connect how PTT-6®️ works with its visible effects.

PTT-6®️is a biological complex produced by nature. It is not a single exosome, lab-grown ingredient. This is why PTT-6®️ can do what other exosome technology can’t.

It’s no miracle. It’s Science®️.

Some results are especially personal.

“I don’t just talk about CALECIM®️—I’ve seen the journey unfold in my own home.

This is my husband, photographed 24 months apart. No stock imagery and no borrowed transformation. I took these photos, followed his progress and watched the changes happen over time.

CALECIM®️ Hair Serum is powered by PTT-6®️, a cell-signalling complex designed to support the scalp and follicle environment and improve the appearance of thinning hair.

As a hairdresser and CALECIM educator, I can explain the science—but sometimes, the pictures tell the story best.” —

This is what two years of consistent, ongoing use looked like for this user. The progress accumulated day by day, as empty-looking areas filled in gradually and each strand of hair gained its strength and resilience.

PTT-6®️ re-invigorates the growth cycle and activates dormant follicles. Sometimes even we are astounded by the results of our users.

The best thing is …the reward isn’t confined to a 12-week milestone. It’s every day afterwards, when the mirror begins to reflect the hair that you feared you had lost forever.

Individual results and timelines may vary.

One of the most interesting things about PTT-6®️ technology is that the benefit rarely appears in just one place.

You may first notice that your skin looks brighter. Then more even. The contours look a little more lifted. Skin feels denser and looks smoother, clearer and more luminous. Even the eye area can begin to look different.

That is because PTT-6®️ is not designed around one isolated cosmetic concern. Its complex of cell-signalling proteins, growth factors and other bioactive factors supports the skin’s own renewal and repair processes — helping skin function more effectively as a whole.

And when skin is functioning better, the changes tend to appear together:

More density. More resilience.
A more even-looking tone.
Greater luminosity.
Smoother texture.
A visibly firmer, more lifted appearance.

It is why sometimes you can see that something has changed without immediately being able to pinpoint what it is.

Your skin simply looks healthier.

And healthy skin tends to look naturally more youthful, rested and beautiful.

Less said. More seen.
We prefer results to promises.

Growth factor skincare deserves more than marketing claims. PTT‑6®️, the proprietary ingredient behind CALECIM®️, has been investigated through both in‑vitro and in‑vivo research published in peer‑reviewed medical journals.

In‑vitro research allows scientists to examine biological activity under controlled conditions. In‑vivo research assesses what happens in living skin. Peer review adds another level of scrutiny, with the research evaluated by experts in the field before publication.

Together, these studies help us understand how PTT‑6®️ supports our body’s natural renewal and repair processes—and why meaningful skin and hair improvement develop progressively over time.

Why this is important? Because you should be confident of your choices and you deserve more than a promise. We believe our trustworthiness as a technology should come from science that can be examined.

“This client came to us concerned about the visible thinning through the top of his hair and wanted to see if we could improve the overall appearance of density and fullness.

We started him on our CALECIM®️ 6-Week Hair Program… and these are his results after just 6 weeks🤍

The difference in the appearance of his hair through that top area has been incredible — it looks fuller, healthier and so much less visibly sparse.” Jacobs Well Hair & Beauty

CALECIM®️ didn’t begin with a beauty brief. Our roots are in biotechnology—and that shaped the way we function.

Before we make anything, we ask: does it serve a purpose? Does it protect the formula? Does it improve the way the product performs?

Our packaging helps preserve the formula. Our signature pink acts as a pH indicator. Our samples contain enough product to be properly experienced. Even the absence of added fragrance is intentional.

Because for us, luxury comes after function. Results come before branding. And every choice must have a reason.

PTT‑6®️. Beauty, logically.

Dark spots, hyperpigmentation and uneven skin tone need more than surface-level brightening.
CALECIM®️ Professional Pigment Solution is a hydroquinone-free dark spot corrector designed to target discoloration at every stage.

Powered by PTT-6®️ and a multi-pathway complex of 4-butylresorcinol, alpha arbutin, tranexamic acid and glutathione, it works on existing discoloration while helping build skin’s resilience against new discoloration.

The change can be easy to miss—until one day, you look again. Skin appears clearer, brighter and more even, and the splotchiness you had grown accustomed to is no longer the first thing you see.

Use morning and night across areas of uneven tone, with a second application directly onto stubborn spots.

This client’s personalized alopecia and hair-loss treatment was managed by our clinical partners Aoife Mullally and Dr Shad at The Good Life Wellness Clinic, combining medical assessment and appropriate scalp treatment with CALECIM®️ Hair Serum and professional microneedling.

After a rapidly enlarging patch of hair loss appeared, medical assessment and blood investigations were carried out to explore possible hormonal, nutritional and other contributing factors. Dr Shad then administered steroid treatment to the affected area.

Following this, Aoife Mullally introduced CALECIM®️ Hair Serum alongside professional microneedling with the Dermapen 4 at a depth of 1 mm. The client completed six weekly treatments.

Visible new hair growth was already evident after four weeks. By five months, there was significant regrowth and noticeably improved coverage.

More than one year later, the result has been sustained—with excellent hair growth, no further patches of alopecia and no ongoing hair fall reported.

This case demonstrates why hair loss is best approached individually. Medical investigation, appropriate treatment, professional care and consistency can all play an important role in achieving—and maintaining—meaningful results.
