As an outstanding factory deeply engaged in the cosmetics field, we have a R&D and manufacturing team that combines professional expertise and rich experience, equipped with a full set of advanced imported production equipment, and have established a standardized and refined production system.

Especially in the field of lip liner factory production, we adhere to strict quality control standards, from raw material selection to finished product delivery, every step is strictly inspected. We use natural and safe ingredients to create with great care, aiming to present high-quality lip liner products that are both luxurious, safe and practical.

1. What specific natural ingredients are used in your factory's lip liner products, and how do you ensure the safety and mildness of these ingredients?

The natural ingredients we use in our lip liner include mainly natural plant extracts, food-grade beeswax, and natural mineral pigments, without artificial preservatives, fragrances or harmful pigments. All raw materials have been tested by authoritative institutions and meet international cosmetic safety standards.

They have also passed skin irritation tests and are suitable for sensitive skin. We have established a raw material traceability system to control the purity of the ingredients from the source, prevent substandard raw materials from entering the production process, and ensure that our products are gentle and non-irritating. 

2. What are the specific strict control links in the production system of lip liner pencils?

We have established a strict full-process control system for lip liner pencils, covering six core links: raw material selection, formula development, mixing and stirring, molding and filling, sterilization and disinfection, and finished product testing. Raw materials need to pass three purity tests before being stored in the warehouse.

During the production process, aseptic workshop operations are adopted, and each batch of products undergoes multiple tests including color, texture, adhesion, and safety. Unqualified products are all destroyed to ensure that every lip liner pencil leaving the factory meets quality standards.

3. What advantages do your factory's imported production machines have over ordinary equipment in the production of lip liner pens?

The imported production machines we have introduced are all from internationally renowned brands. Compared with ordinary equipment, they have three core advantages:

first, they offer higher precision, enabling precise control over the thickness and uniformity of the lip liner's core, and preventing issues such as core breakage and clumping;

second, they have higher production efficiency, allowing for batch standardized production while retaining the delicate texture of handcrafted products;

third, they are more environmentally friendly, featuring low energy consumption and low emissions, with no harmful waste generated during the production process, aligning with the concept of green production.
4. What are the core capabilities and R&D directions of the R&D team in the iteration of lip liner products?

Our R&D team is composed of senior engineers and formula developers with over 20 years of experience in lip liner pen research and development in the cosmetics industry. Our core capabilities lie in accurately grasping market trends, optimizing product formulas, and enhancing user experience.

Our R&D focus is mainly on three points: first, developing formulas that are more long-lasting and less prone to smudging, to meet the needs of different scenarios; second, introducing more natural color series to satisfy diverse aesthetic preferences; third, improving the texture of the pen core to create a smooth, easy-to-apply, non-streaking, and non-drying application experience, while balancing beauty and practicality. 

5. Do the quality control standards for lip liner pens comply with relevant international and domestic industry norms?
Our lip liner's quality control standards strictly adhere to the domestic "Cosmetics Safety Technical Specifications" (2022 Edition), and also comply with international authoritative certification standards such as the EU CE and the US FDA. Every indicator meets or exceeds industry norms.

We have established a complete quality inspection laboratory, equipped with professional testing equipment, to conduct comprehensive tests on the product's heavy metal content, microbial indicators, and irritancy, ensuring the product's safety and compliance, and making it exportable to many countries and regions around the world.
6. What are the requirements for the shelf life and storage conditions of lip liner made from natural ingredients?
Due to being made from natural ingredients and without the addition of artificial preservatives, the shelf life of our lip liner is 18 months (unopened). After opening, it is recommended to use it up within 6 months to ensure its freshness and effectiveness.

Storage conditions should be noted: avoid placing it in high-temperature, direct sunlight, or humid environments. It is suggested to store it in a cool, dry, and well-ventilated place, out of reach of children, and also avoid collisions with sharp objects to prevent the core from breaking and the shell from being damaged.


7. Could your factory customize lip liner products of different specifications and color series according to customer requirements?

Sure, we have professional customized production capabilities. We can customize lip liner products of different specifications, color series and packaging according to the specific needs of customers. Whether it is the thickness of the pen core, texture (matte, moisturizing, velvet), color series blending or packaging design, we can combine the customer's requirements, and the R&D team will optimize the formula and design the plan, while the production team will accurately implement it.

At the same time, we strictly follow the original quality control standards to ensure that the quality of customized products is consistent with that of regular products, meeting the personalized needs of customers.

8. How can common problems such as broken cores and uneven coloring of lip liner be avoided during the production process?
To prevent problems such as broken cores and uneven coloring of lip liner, we strictly control two core links: first, the raw material ratio. The R&D team has conducted repeated experiments to optimize the ratio of beeswax, plant oil and color powder, ensuring that the core is tough and not easy to break, while also ensuring that the color powder is evenly distributed. Second, the production process.

We use imported molding equipment to precisely control pressure and temperature, ensuring that the core is fully formed and has a fine texture. Subsequently, it undergoes multiple grinding and inspection processes to eliminate substandard products, fundamentally eliminating problems such as broken cores and uneven coloring.

9. What is the production cycle of your factory's lip liner pencils approximately? How is the delivery capacity for bulk orders?
The production cycle of our lip liner pencils is determined by the order quantity. For regular bulk orders (1,000 - 10,000 pieces), the production cycle is 7 to 10 days. For large bulk orders (over 10,000 pieces), the production cycle is 10 to 15 days. If there are customized requirements, the production cycle will be appropriately extended by 2 to 3 days depending on the complexity of the customization.

We have sufficient production capacity, equipped with multiple imported production lines, and can handle multiple batches of orders simultaneously. We strictly adhere to the agreed delivery time to ensure that it does not delay the customer's market launch plan, while also guaranteeing the stable quality of each batch of products. 

10. How can you prove the quality of your factory's lip liner pens? Do you provide relevant test reports or samples?
We can provide quality inspection reports issued by authoritative institutions for our lip liner pencils, including component testing, safety testing, and quality index testing, to ensure the transparency and traceability of product quality. Meanwhile, we offer free samples to customers for on-site testing of core performance such as texture, color application effect, and durability.

Additionally, customers can make appointments at any time to visit our factory to inspect the production process and quality control procedures on-site, and gain a direct understanding of our production capabilities and product quality, thus eliminating any quality concerns.
