Quality Control

Quality Control

Rensino Aesthetic Medicine Co., Ltd. applies structured quality control procedures to products developed for professional aesthetic medicine and skin care applications. Our quality approach supports product categories such as acne and scar care, pigmentation management, skin rejuvenation, anti-aging treatments, facial and body contouring, hair care, and post-operative skin repair supplies. From material receipt to final shipment, inspections are performed according to internal inspection standards, approved specifications, and applicable industry-aligned practices.

Quality requirements may vary according to product type, formulation, component, intended application, and customer specifications. We therefore define relevant inspection criteria before production and maintain production and inspection records to support consistency and traceability where applicable.

1. Incoming Material Inspection

Raw materials, packaging materials, components, and accessories are checked before they are released for production. Our team verifies supplied materials against purchasing requirements and approved product specifications, with additional attention given to characteristics that may affect safety, performance, appearance, or shelf stability.

• Supplier and document review: Supplier information and available material documentation are reviewed according to sourcing and product requirements.
• Identity and specification checks: Material names, grades, quantities, batch information, and relevant technical parameters are verified where applicable.
• Visual inspection: Materials and components are examined for contamination, damage, leakage, deformation, discoloration, or other visible defects.
• Packaging component checks: Bottles, tubes, pumps, caps, applicators, labels, cartons, and protective materials are assessed for compatibility, condition, and dimensional conformity as required.
• Material status control: Accepted, pending, and nonconforming materials are identified and handled separately to reduce the risk of unintended use.

2. In-Process Quality Control

Quality is monitored throughout production rather than relying only on final inspection. Process parameters and inspection points are established according to the characteristics of each product. This is particularly important for products intended for sensitive skin care, acne management, brightening, anti-aging, pore care, scar repair, and other professional aesthetic applications where consistency is essential.

• Production setup verification: Materials, equipment, work instructions, and packaging components are checked before processing begins.
• Process parameter monitoring: Relevant operating conditions are observed and recorded subject to the manufacturing method and product specification.
• In-process sampling: Samples may be assessed for appearance, color, odor, texture, uniformity, fill quantity, dimensions, assembly, or other defined attributes.
• Hygiene and handling controls: Work areas, tools, containers, and handling practices are managed according to applicable internal cleanliness requirements.
• Line clearance and identification: Materials and work-in-progress products are identified to help prevent mix-ups between batches, variants, labels, or customer orders.

If an in-process result does not meet the specified acceptance criteria, the affected material is held for review. Production proceeds only after the issue has been evaluated and an appropriate disposition has been determined.

3. Finished Product Inspection

Finished products are inspected against approved specifications before release. The inspection scope is selected according to the product format and intended use, whether the order relates to skin rejuvenation products, pigmentation and melasma care, eye-area and facial anti-aging products, contouring-related items, scalp and hair care, or post-operative repair supplies.

• Appearance and workmanship: Products are checked for visible defects, contamination, damage, leakage, inconsistent finish, or improper assembly.
• Physical characteristics: Relevant attributes such as dimensions, weight, fill quantity, texture, uniformity, and component fit are evaluated where applicable.
• Functional checks: Pumps, closures, dispensers, applicators, seals, and other functional components are tested according to product requirements.
• Label and print verification: Product names, variants, batch details, usage information, and customer-approved artwork are checked for accuracy and legibility.
• Specification-based testing: Additional testing may be arranged or performed when required by the product specification, intended market, or agreed customer quality plan.

Inspection records are maintained as appropriate to the order and product type. Any nonconforming product is identified, segregated, and reviewed before a release decision is made.

4. Packaging and Pre-Shipment Check

Packaging is reviewed not only for presentation but also for its ability to protect products during storage and international transportation. Packaging methods are selected according to product sensitivity, format, order configuration, and agreed customer requirements.

• Primary packaging review: Containers, closures, seals, and contact surfaces are checked for cleanliness, integrity, and correct assembly.
• Secondary packaging review: Individual cartons, inserts, labels, and protective materials are verified against the approved order details.
• Shipping carton inspection: Carton condition, product arrangement, internal protection, quantity, and shipping marks are checked before dispatch.
• Order reconciliation: Product models, variants, quantities, packaging versions, and customer-specific requirements are compared with the sales and production documents.
• Pre-shipment review: Relevant inspection results and shipment information are reviewed before goods are released for delivery.

5. Feedback, Corrective Action, and Continuous Improvement

Rensino Aesthetic Medicine Co., Ltd. treats customer feedback as an important part of quality management. When a quality concern is reported, our team collects relevant information such as the product name, batch details, photographs, packaging condition, and description of the issue. The information is reviewed with the responsible production, quality, sourcing, or packaging personnel.

Depending on the nature of the issue, the review may include record verification, retained-sample assessment where available, material review, process evaluation, or packaging analysis. Appropriate corrective and preventive actions may then be introduced, such as updating inspection criteria, improving work instructions, adjusting process controls, strengthening supplier communication, or refining packaging methods.

Our objective is to provide international B2B customers with clear quality communication, consistent order execution, and products manufactured and inspected according to defined requirements. Customer-specific quality points can be discussed during product development, sampling, private-label preparation, and order confirmation.
