The DERMA-X Development Journal
Behind the Nighttime Formula
DERMA-X Night Renewal is being
developed as a nighttime cosmetic
cream featuring Hydroxypinacolone
Retinoate (HPR), a retinoid ester.
The project combines emulsion
formulation research with the
evaluation of selected skincare
ingredients and their compatibility
within a cream-based system.
Earlier prototype work involved
preparing the water and oil phases,
observing the emulsion during cooling,
reviewing formulation texture,
and recording preliminary pH
measurements.
These development observations
are preliminary. They do not
establish finished-product
safety, long-term stability,
or demonstrated skin benefits.
Product Format
HPR-containing nighttime cream
in a proposed 2 oz cosmetic jar
Featured Ingredient
Hydroxypinacolone Retinoate (HPR),
selected for the formulation
Development Status
Active formulation refinement.
Release date not announced.
01 / Ingredient Research
Exploring the Components
The following ingredients have
been selected, used in earlier
prototypes, or considered during
development. The final commercial
ingredient list remains subject
to formulation review.
Featured Retinoid Ingredient
Hydroxypinacolone Retinoate (HPR)
Hydroxypinacolone Retinoate
is a retinoid ester selected
for inclusion in the
DERMA-X Night Renewal
formulation.
Our research focuses on its
incorporation into the cream,
compatibility with selected
ingredients, and the effects
of formulation conditions
on its chemical stability.
Light exposure, oxidation,
packaging suitability,
and appropriate safety
assessment are areas
for further evaluation.
The final active HPR
concentration has not
been established for release.
The percentage of HPR in
a supplied ingredient solution
should not be confused with
the concentration in the
finished cream.
Emollient Research
Olive Squalane
An emollient used in the
exploratory cream base.
Development work considers
its influence on the
sensory characteristics,
spreadability, and
texture of the emulsion.
Oil Phase Research
MCT Oil
A lightweight oil component
incorporated into an earlier
prototype as part of
the formulation's oil phase.
Emulsion Development
Emulsifying Wax & Cetyl Alcohol
Ingredients used in developing
the preliminary cream structure.
Their roles include helping
form the oil-and-water emulsion
and influencing its viscosity
and texture.
Peptide Research
GHK-Cu & SNAP-8
These peptides have been
explored within the broader
DERMA-X development program.
Their suitability for the
final HPR-containing Night
Renewal formulation has
not been established.
Supporting Cosmetic Ingredients
Additional Formulation Components
Niacinamide, azelaic acid,
hyaluronic acid, and other
cosmetic ingredients have
been considered during
DERMA-X development.
Final inclusion and
compatibility remain
subject to evaluation.
02 / Formulation Development
Developing the Night Cream Base
Our exploratory formulation
work focuses on developing
an oil-and-water emulsion
suitable for further
ingredient compatibility
research.
01
Preparing the Phases
Water and oil phases were
prepared separately during
earlier exploratory work.
02
Emulsion Formation
The prepared phases were
combined and mixed to
develop the initial
cream structure.
03
Cooling & Evaluation
The emulsion was observed
during cooling for changes
in texture, consistency,
and appearance.
04
HPR Formulation Research
Ongoing development considers
how the selected retinoid
can be incorporated while
evaluating compatibility,
stability, and suitable
formulation conditions.
03 / Development Journal
What We've Observed So Far
Selected observations from
earlier cream prototype work.
These do not constitute
validated stability or
safety test results.
Initial Emulsion Formation
An exploratory batch produced
a cream-like emulsion after
preparation and mixing
of the water and oil phases.
Texture and Appearance
The initial cream base
appeared light yellow
and visually uniform
during early observations.
This does not confirm
long-term stability.
Preliminary pH Observation
An earlier prototype
produced a recorded pH
reading of approximately
4.46. This is an
exploratory measurement,
not a finalized product
specification.
Exploratory Concentrate Addition
A separate test jar
was used to observe
incorporation of a
previously prepared
daytime concentrate.
Its initial appearance
was observed, but
long-term compatibility
was not established.
HPR Development Priorities
The HPR-containing formulation
requires further evaluation
of chemical stability,
processing conditions,
packaging, and ingredient
compatibility. No validated
HPR stability results are
being reported at this stage.
04 / Current Project Status
Where Development Stands
DERMA-X Night Renewal
— In Development
HPR has been selected as
a featured component of
the Night Renewal formulation.
Work continues on the
cream base, ingredient
compatibility, and
formulation refinement.
The commercial formula,
active HPR concentration,
shelf life, and release
date have not yet been
finalized.
Areas requiring additional
evaluation include:
HPR chemical stability,
including light and
oxidation sensitivity
Emulsion texture and
physical stability
Ingredient compatibility
and formulation pH
Preservative effectiveness
and microbiological safety
Appropriate retinoid
safety assessment,
warnings, and labeling
