I'm looking for information on a range of ingredients for a project focused on skin health and pigmentation. Specifically, I'm interested in Kojic Acid Dipalmitate, Lithium Orotate, Vitamin D3, K2, Copper, Vitamin B12, Tyrosine, Vitamin B9, and Omega 3. Could you provide insights on the efficacy and natural benefits of these compounds in stimulating and activating melanocytes? Additionally, I'd appreciate any recommendations on the most effective natural methods or formulations you have available that can support melanocyte activation. Understanding how these ingredients work individually and in synergy would be extremely helpful as I move forward with my decision-making process. Thank you for your assistance!
