Alejandra H.

I am Alejandra, a Ph.D. Chemist and Pharmacist with strong expertise in Cosmetic Formulation, Skincare Product Development, and Natural Ingredients Chemistry. I worked as a scientist in academia, focusing on natural products chemistry, including natural polymers, herbal extraction, quality control, and the formulation of active ingredients. Since 2002, I have been running my own consulting business specializing in Cosmetic Product Formulation. I help brands create innovative and market-ready products.. My work covers formula design, ingredient selection, and scientific consulting for lotions, serums, moisturizers, masks, cleansers, hydrogels, and more. I deliver custom cosmetic formulas (vegan, paraben-free, plant-based, clean beauty) and improve them according to client feedback and testing. I also contribute to AI training projects, providing professional data labeling, knowledge structuring, and scientific input for systems focused on cosmetic science, natural products, and pharmaceutical chemistry. If you are looking for a cosmetic chemist, skincare formulation expert, or AI training consultant with proven experience, I would be glad to collaborate on your project.
