Clinical Evidence for GHK Peptide
A 6-month randomized, double-blind, placebo-controlled study found that a 5-ALA + GHK peptide complex increased hair count by up to 71.5 hairs, compared with 9.6 in the placebo group.
CAREL Scientific Skincare System
From ingredients to formulation, we build science-backed skincare
designed to work in synergy.
Beyond Ingredients.
Built to Work Together.
CAREL formulas are more than a collection of actives.
We carefully consider ingredient synergy, stability, efficacy, and skin compatibility—so every active works better together.
Through scientific selection and optimized formulation, we help each ingredient perform at its best.
Four Technology Pillars
Four core technologies guide our ingredient selection, formulation,
and skin research—turning science into real product performance.
High-Purity Peptide Fusion
Peptide performance depends on more than concentration—it starts with purity, structure, and formulation compatibility.
Advanced Active Stabilization
We help key actives stay stable and perform effectively within the formula.
Biomimetic Barrier Lipids
Supports the skin barrier to help retain moisture, maintain balance, and defend against external stressors.
Sensitive Skin Research
Sensitive skin calls for science that is precise, thoughtful, and carefully formulated.
PeptiFusion™ Tri-Core Synergy
CAREL builds on peptide science with its proprietary PeptiFusion™
Tri-Core Synergy System.
Traditional formulas focus on what goes in. PeptiFusion™ goes further—focusing on how ingredients work together.
Powered by peptides, three functional cores integrate signaling, active performance, and skin adaptability to create more coordinated, multi-level skincare.
Four Dimensions of Skin
CAREL evaluates every formula through four dimensions: ingredients,
mechanisms, people, and environment—creating skincare designed
for real skin in real life.
Ingredient Dimension
We consider ingredient purity, efficacy, stability, and compatibility—because performance is more than simply adding more actives.
Mechanism Dimension
We look at key skin processes, from signaling and barrier support to hydration and antioxidant defense.
People Dimension
We consider age, skin type, sensitivity, and lifestyle to create skincare for different needs.
Environment Dimension
Climate, humidity, UV exposure, pollution, and daily stress can all affect skin. Our formulas are designed with these real-world factors in mind.
CAREL Core Ingredients
CAREL selects advanced actives for a reason.
Each ingredient plays a clear role, optimized through formulation,
stability, and PeptiFusion™ synergy to deliver better skin performance.
GHK-CU
Supports skin repair, firmness, and resilience.
SNAP-8
Helps soften the look of expression lines for smoother-looking skin.
Pro-Xylane
Supports skin density, elasticity, and moisture retention.
Sodium Hyaluronate
Delivers lasting hydration for plumper, smoother-looking skin.
