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.
