Exploring Peptide Science

Built on active peptide science, CAREL develops precise, effective, and gentle skincare solutions.

01 Why We Start with Peptides

Unlike ingredients that simply replenish moisture or lipids, peptides are active signaling molecules composed of amino acids. By participating in skin signaling pathways, they can support repair, firmness, and visible signs of aging.

At CAREL, peptides are the scientific starting point—not simply another ingredient added to a formula. Our formulations are built around targeted peptide technology, sensitive-skin compatibility, and measurable efficacy, creating a more structured and science-driven approach to skincare.

02 PeptiFusion™ Three-Core Synergy

From Individual Ingredients to Systematic Synergy

CAREL’s proprietary PeptiFusion™ technology system integrates three interconnected cores: the Peptide Signal Core, Functional Active Core, and Local Adaptation Core.

Each plays a distinct role in signaling, active support, and environmental adaptation. Rather than simply layering ingredients together, every formula is systematically designed around how ingredients work together.

Peptide Signal Core

Delivering Targeted Skin Signals

Active peptides function as signaling factors within the formula, supporting specific skin-care pathways and helping other functional ingredients work in a more coordinated way throughout the repair process.

Functional Active Core

Supporting Skin with Targeted Actives

Botanical extracts, biotech-derived ingredients, and other functional actives are selected according to different skin needs, providing multidimensional support for hydration, firmness, soothing care, antioxidant protection, and barrier support.

Local Adaptation Core

Adapting to Skin and Environment

Regional temperature, humidity, lifestyle, and skin conditions are considered when optimizing formula structure and sensory experience—helping each product better respond to real-world skin needs.

03 Peptide Structure & Formula Synergy

Peptide Synthesis & Purification Technology

Advanced technologies including segmented long-peptide synthesis, targeted cyclic peptide synthesis, RP-HPLC, and rapid chromatography are used to support peptide purity and quality.

High-Performance Stability Technology

Active encapsulation, targeted delivery, and pH stabilization technologies help protect active ingredients and maintain up to 90% of their activity when the formula comes into contact with skin.

DDS Delivery System

A delivery structure designed with lipid ratios inspired by the skin barrier, combined with micro- and nano-scale delivery technologies to support ingredient compatibility and delivery.

Sensitive-Skin Formulation Technology

High-purity peptides are combined with formulations specifically developed with sensitive skin in mind.
