Hi, my name is Dragica, a Doctor of Medical Science (PhD), pharmacist, and toxicologist. I specialize in cosmetic product safety assessment and regulatory compliance, helping brands ensure their products are safe, scientifically justified, and compliant with EU and UK cosmetic regulations. During my PhD and professional work, I have focused extensively on toxicology, safety evaluation, immune-modulating compounds, natural ingredients, and exposure-related health risks. This background allows me to assess cosmetic products with a robust, evidence-based approach, covering both conventional and natural formulations. What I can help you with: • Cosmetic Product Safety Reports (CPSR) – drafting and review • Product Information Files (PIF) – compilation and compliance checks • Toxicological risk assessment of cosmetic ingredients and finished products • Margin of Safety (MoS), exposure assessment, TTC and read-across approaches • Safety evaluation of natural ingredients, botanicals, supplements, and cosmetics • Assessment of ingredient interactions, cumulative exposure, and special populations • Review of raw material documentation, formulations, and supplier data As a pharmacist and toxicologist, I am trained to evaluate both beneficial and adverse effects of cosmetic ingredients and to identify potential interactions, contraindications, and safety concerns, including for consumers with chronic conditions or long-term exposure. I am known for being highly organized, detail-oriented, and reliable, able to work independently while delivering accurate, regulator-ready documentation. My goal is to make compliance clear and efficient, so you can move forward with confidence. 💡 If you need a knowledgeable and dependable cosmetic safety expert who combines medical science with practical regulatory insight, I would be happy to support your project.

I am a chemistry/biology/physics PhD (the title itself was obtained at an engineering school but the context was systems biology) with a wealth of experience in scientific research. I have been a part of a few scientific research projects in the fields of chemistry/biomedicine/biophysics/omics and am a published author in my field(s). Other than working in a laboratory writing is what I enjoy the most. From writing poetry and short stories (mostly for my own pleasure) to essays and academic research papers, all things writing suit me. If they are related to science, even better. Even if they are not, I am a person of many interests, I adore history, culture, art, philosophy, etc. I am available also for diverse scientific work, including interpretation of analytical chemistry data (mass spec, NMR, HPLC), solving various problems in the fields of chemistry/physics/biology. I pride myself on being a very analytical and patient individual, as well as intelligent and able to grasp concepts previously unknown to me very quickly. I actually do this on a regular basis, challenge myself and try to learn about things outside of my main interests. When it comes to writing, I am familiar with most citation styles used in academia, and am able to follow guidelines well. I do have a specific writing style and I like to leave my distinct mark on the writing I do.
