Understanding Your OEM Needs
Before evaluating potential OEM partners, you must clearly define your brand's specific requirements. This foundational step determines which manufacturers can truly meet your needs and ensures a successful long-term partnership.
Critical Questions to Answer First
- Product Type: Sheet masks, hydrogel patches, serums, creams, or multi-product lines?
- Volume Requirements: Initial order quantity and projected annual volume
- Budget Range: Per-unit cost targets and total investment capacity
- Timeline: Product development, testing, and launch schedule
- Target Markets: Geographic regions and regulatory requirements
- Brand Positioning: Premium, mid-range, or mass-market segment
Product Specialization Matters
Not all OEM factories excel at every product type. Korean manufacturers, for example, have developed world-leading expertise in specific categories:
Hydrogel Specialists
Factories with advanced hydrogel technology, precision molding equipment, and sterile production environments. Ideal for eye patches, face masks, and body patches.

High-volume production capabilities with multiple material options (cotton, bamboo, bio-cellulose). Best for brands requiring large quantities.
Explore OptionsFactory Evaluation Criteria
A systematic evaluation framework helps you objectively compare potential OEM partners. Here's the comprehensive checklist used by successful skincare brands:
1. Production Capacity and Scale
Facility Size and Equipment
Minimum 10,000 sqm for serious manufacturers. Look for automated production lines, clean rooms (ISO 7 or better), and modern quality control laboratories.
Monthly Production Volume
Top-tier factories produce 5-10 million units monthly. Verify they can handle your current needs plus 50-100% growth without quality compromise.
Lead Times and Flexibility
Standard lead time: 45-60 days from order to delivery. Rush capabilities and seasonal demand handling are crucial for market responsiveness.
2. R&D and Formulation Expertise
The best OEM partners don't just manufacture—they innovate. Evaluate their research and development capabilities:
Must-Have Capabilities:
- In-house formulation chemists
- Stability testing facilities
