Adding Active Ingredients to Clay Mask Powder

Regarding your question about adding Vitamin B3, Vitamin B6, Zinc PCA, and Green Tea Extract to the dry clay mask powder mix:

Adding these active ingredients to the dry clay powder is possible, but it is generally not recommended. As previously mentioned by the staff, active ingredients are less effective when used in a wash-off product like a clay mask because the clay can hinder their absorption into the skin.

For these active ingredients to provide their intended benefits (whitening, strengthening skin, helping with acne scars/pores), they are best incorporated into leave-on formulations such as serums, gels, or water-based essences, where they can remain on the skin and be properly absorbed.

Therefore, while you can technically mix them into the powder, you would not get the full benefit of these ingredients when using the mask. It is more effective to use these actives in a separate leave-on product.
