Korean formulation
Blion:Cell skincare is made in Korea, drawing on sophisticated cosmetic formulation and delivery-system development.
THE SCIENCE
Advanced Korean skincare, explained.
Blion:Cell pairs Korean formulation expertise with carefully selected, high-quality ingredients, purposeful concentrations, sensorial textures and product-specific evidence where available.

PDRN, EXPLAINED
1% pure PDRN. 10,000 ppm in the finished formula.
Collagen Expert V is formulated with 1% pure PDRN powder—not 1% of a diluted PDRN solution. That means the finished ampoule contains a full 10,000 ppm of PDRN. In cosmetic ingredient labeling, the material appears as Sodium DNA.
Finished-formula PDRN1% · 10,000 ppm
Why the distinction matters: two products can both reference “1% PDRN” while containing very different actual amounts if one number refers to pure PDRN and the other refers to a pre-diluted raw-material solution.
Comparisons between products should use documented raw-material specifications and finished-formula calculations. We do not claim that every competing formula uses diluted PDRN.
OUR APPROACH
Science should clarify the formula—not complicate it.
We organize Blion:Cell science around three things: where the formulas are made, what is actually in them, and what has been measured on the finished product. Clinical findings are always presented as product-specific, while supplier technologies and ingredient stories are identified as formulation information.
Purposeful systems
We prioritize ingredient quality, meaningful concentrations and complementary systems rather than adding trend ingredients at token levels. Humectants, soothing ingredients, peptides, lipids and skin-conditioning agents are chosen to serve a clear purpose.
Evidence where available
When finished-product human testing exists, we highlight exactly what was measured, under what protocol, and in which study population.
INGREDIENT SYSTEMS
Designed to work as a formula.
The collection repeatedly returns to hydration, soothing support, peptides and modern skin-conditioning technologies—expressed differently in each product.
SOOTHECentella + Azulene
Azulene Cica Plus is centered on 66.8% Centella Asiatica Leaf Water with niacinamide, panthenol and Sodium Guaiazulene Sulfonate—an azulene-derived soothing ingredient that also gives the ampoule its distinctive blue hue.
Featured in Azulene Cica PlusELASTICITYCollagen + Peptides
Collagen Expert V combines Collagen Water, Sodium DNA, niacinamide, hyaluronic acid, vitamin C and a multi-peptide blend including Copper Tripeptide-1 to support a firmer, smoother, more radiant appearance.
Featured in Collagen Expert VREPLENISHCica + Ceramides
Rejuvina Cica combines Centella-derived components, ceramides, multiple hyaluronic acid forms, peptides and Sodium DNA in a richer cream format.
Featured in Rejuvina Cica Intensive CreamPDRNSodium DNA
Collagen Expert V is formulated with 1% pure PDRN powder, equivalent to 10,000 ppm in the finished formula. The INCI identifies this material as Sodium DNA. This is distinct from formulas that describe the percentage of a diluted PDRN solution rather than the actual PDRN content of the finished cosmetic.
Featured in Collagen Expert V + Rejuvina CicaHYDRATEMulti-form Hyaluronic Acid
Different forms and molecular weights of hyaluronic acid and hyaluronate salts can be combined to create a layered hydration and skin-feel system.
Featured prominently in Rejuvina CicaSIGNALMulti-peptide blends
Blion:Cell formulas use multiple cosmetic peptides rather than treating “peptides” as a single ingredient category.

AZULENE CICA PLUS
The blue comes from the formula.
That signature blue hue is not simply decorative. Azulene Cica Plus contains Sodium Guaiazulene Sulfonate, a water-compatible azulene derivative used for its soothing skin-care properties. It is paired with a 66.8% Centella Asiatica Leaf Water base, niacinamide, panthenol and humectants to support visibly calm, hydrated, comfortable-looking skin.
Azulene-derived soothing ingredient2,000 ppm
This azulene-derived calming ingredient is listed on the INCI as Sodium Guaiazulene Sulfonate, giving the formula its distinctive blue hue while supporting soothing cosmetic care.
Azulene Cica Plus is not formulated with Copper Tripeptide-1 or another intentionally added copper peptide. Sodium Guaiazulene Sulfonate itself is not a copper compound.
COLLAGEN EXPERT V · HUMAN APPLICATION STUDY
Anti-aging focus, with elasticity measured after one use.
Collagen Expert V is designed to address visible signs of aging including loss of firmness, elasticity, smoothness and radiance. In a finished-product human application study, cheek elasticity was evaluated before and after a single application.
What was measuredCheek elasticity (Coefficient of Restitution) using a Ballistometer BLS780.
Who participated23 healthy Korean adult women; average age 52.3 years.
Single-use cosmetic study in 23 healthy Korean adult women. The study report states that no special adverse skin reactions were reported or observed during the study period. Results apply to the tested product, population and protocol; individual results may vary.
HUMAN PATCH TESTING
Finished-product tolerability, tested on skin.
Separate primary skin irritation patch tests were completed on Collagen Expert V Ampoule and Rejuvina Cica Intensive Cream at Human Skin Clinical Trial Center Co., Ltd. Each finished product received a Skin Irritation Index of 0.00 and was classified by the study center as “No irritation (Excellent)” under the study protocol.
COLLAGEN EXPERT V AMPOULE
0.00No irritation (Excellent)
34 healthy adult subjects completed the primary skin irritation patch test. The product was applied in a Finn Chamber® for 24 hours and evaluated by a dermatologist after patch removal.
REJUVINA CICA INTENSIVE CREAM
0.00No irritation (Excellent)
34 healthy adult subjects completed the primary skin irritation patch test. The product was applied in a Finn Chamber® for 24 hours and evaluated by a dermatologist after patch removal.
Primary skin irritation patch tests are short-term tolerability evaluations under controlled study conditions. “No irritation (Excellent)” is the study center’s classification for an irritation index of 0.00 and does not mean that an individual can never experience sensitivity or an allergic reaction.
REJUVINA CICA · FORMULATION TECHNOLOGY
Multiple systems, one recovery-minded cream.
The supplied Rejuvina materials describe a complex formula featuring U-Oliosome TECA1, PDRN/Sodium DNA, nine listed growth-factor-type oligo/polypeptide ingredients, ten forms or weights of hyaluronic acid, and six peptides.
01
U-Oliosome TECA1
A supplier-described carrier/formulation technology used with TECA1 components. We present this as formulation information rather than proof of dermal penetration.
02
10-HA hydration system
A combination of multiple hyaluronic acid and hyaluronate forms designed to support hydration and sensorial skin feel.
03
Peptides + ceramides
A multi-peptide and lipid-supporting approach within a richer cream designed for skin that feels dry, stressed or depleted.
Supplier illustrations and descriptions of U-Oliosome, growth-factor-type ingredients and delivery behavior are not presented as finished-product clinical proof. Cosmetic claims on this site are intentionally limited to supported appearance, hydration and skin-conditioning language.
OUR EVIDENCE STANDARD
Product-specific means product-specific.
Ingredient quality and concentration matter, but so does the evidence behind a claim. Supplier documentation can establish raw-material specifications and delivery concepts; finished-product human testing tells us what was actually measured on the exact cosmetic. We keep those categories separate so you can understand what each statement really means.
