SCIENCE

TRANSLATING SCIENCE WITH CARE

Scientific precision,
translated for skin

Scientific background, cosmetic ingredients and product design each carry a different meaning. We keep them distinct and present information that can be checked.

TWO FOUNDATIONS

From source science
to cosmetic ingredients

Research papers are the source of scientific insight; they do not by themselves prove the efficacy of a finished cosmetic. Finished-product results are presented separately on Evidence & Results.

01

Source Science

Published scientific context—including extracellular-vesicle research—and the relationship between researchers, institutions and papers.

02

Ingredient Translation

Nomenclature, quality review and registration information needed to translate research context into a cosmetic ingredient.

FROM ORGAN REGENERATION TO CONSUMER SCIENCE

From medical research
to everyday skincare

tiptop’s public Source Index connects organ-regeneration research, clinical development, regulatory records, ingredient development and manufacturing in Japan without confusing their owners or meanings. CELLshot is a cosmetic brand—not a medicine—and inherits this discipline of research and quality.

ORIGINAL SCIENCE

Nature → Science Translational Medicine

From lung-regeneration research published in Nature in 2015 to a 2024 Science Translational Medicine clinical study of autologous P63+ lung progenitor cells.

Nature / PMID 25383540 ↗
CLINICAL DEVELOPMENT

IND Pathway / Registered Trials

The investigational pathway and multi-stage clinical-research records, including Phase I/II studies publicly registered on ClinicalTrials.gov.

ClinicalTrials.gov / NCT02745184 ↗
REGULATORY RECORD

U.S. FDA Orphan Drug Designation

Regend Therapeutics Co., Ltd.’s autologous cell product derived from human airway basal cells received U.S. FDA orphan-drug designation for IPF on February 4, 2025. This is not marketing approval.

CONSUMER TRANSLATION

powered by tiptop → CELLshot

tiptop translates public science into original ingredients, freeze-drying, packaging, quality review and manufacturing in Japan. CELLshot brings that technical path into daily skin rituals.

FORMULATION DESIGN

Freeze-dried
Mixed immediately before use

Powder and liquid remain separate during storage, then become one at the moment of use. CELLshot’s two lead products bring this philosophy into daily care through different packaging structures.
