Can you do custom formulation?

Yes, MAYK offers custom formulation (OEM) services tailored to your brand's needs.

For brands looking to create unique products, our service allows you to work with experienced Korean R&D labs to develop custom skincare formulations. This includes selecting active ingredients to customizing texture, scent, and performance.

MOQs start at 1,000 pcs for basic packaging options, and 3,000 pcs or more for more advanced or fully customized packaging.

2. Fill in a form to specify your requests (eg. ingredients that must be included).

Can I cancel a sample order and get a refund?

For retail-ready formulation samples, we also do not offer refunds.

If your sample arrives damaged, please contact us within 7 days of receiving it with a photo. We'll take care of it as soon as possible!

What is the minimum order quantity (MOQ)?

Most Korean manufacturers usually require 5,000 units or 10,000 units MOQ for basic skincare products. However, our network of manufacturers enables us to offer MOQs as low as 1,000 units for custom formulation/OEM products.

For ready-made Retail-Ready Formulations, our lowest minimum order quantity is 50 units. This is the lowest manufacturing MOQ in Korea, and it is only exclusively available at MAYK. This is only limited to the items listed on our catalog.

What is the cost per unit for custom formulation?

For custom formulations, the cost per unit depends on the product category, packaging, ingredients, and overall complexity of the formulation.

As a general rule of thumb, the cost per unit typically ranges between $4~5 for skincare products, and about $1 for sheet masks.

What if we want to use a specific ingredient in the custom formula?

For custom formulations, we will try to source for the ingredients you requested. However, we prioritize raw materials stocked by our manufacturing partners or supplied through their trusted sources. If specific ingredients are difficult to source, we may recommend alternatives with similar efficacy to meet your formulation needs.

What is the typical lead time for the production of skincare products?

For Retail-Ready Formulations, it usually takes 2-3 weeks to produce after confirming your label designs.

For Custom Formulations, it usually takes 6-8 weeks to produce after confirming your label designs.

Can I choose the manufacturer I want to work with?

Yes, but only for Custom Formulation orders, and only if your MOQ is at least 5,000pcs per product. Do note that we will also suggest manufacturers that are suitable for your needs, and you may not be able to work with your ideal manufacturer depending on your requirements (eg. specific certifications for specific countries).

For Retail-Ready Formulations, since the products are ready-made, it is not possible.

Can I partner with Kolmar to create my products?

Yes, but only for Custom Formulation orders, and only if your MOQ is at least 5,000pcs per product. Do note that we will also suggest manufacturers that are suitable for your needs, and you may not be able to work with your ideal manufacturer depending on your requirements (eg. specific certifications for specific countries).

How many samples can I receive?

Retail-Ready Formulations: You can purchase samples for each product from our catalog. For $20, you will receive one sample for one product.

Custom Formulation:

1. Initial sample: We'll create a sample based on your initial consultation and preferences.

2. Revised sample: We'll create a revised sample reflecting your feedback on the initial sample.

3. If you still want to make further refinements after the first two, additional sample revisions are available for $69 each.

Are samples refundable?

Since we custom-create samples specifically tailored to your product development needs, we cannot offer refunds. This is because the cost of the ingredients, packaging and shipping is factored into our service fees.

However, if your sample arrives damaged, please contact us within 7 days of receiving it with a photo. We'll take care of it as soon as possible!
