What Is Cosmetic Science? A Guide to the Field and Its Careers

Did you know that the average American adult uses between 6 and 12 personal care products and cosmetics every day?

Cosmetic scientists play a vital role not only in conceiving and formulating new products but also in ensuring they are safe for consumers.

If you love makeup, skincare, and haircare and want a creative career that combines beauty with science and chemistry, read on to learn more about this field and the career possibilities it offers.

Cosmetic science encompasses the research, development, and production of beauty and personal care products, from the shampoo and toothpaste you use every day to makeup, perfume, sunscreen, and specialty skin care.

Cosmetic science is a broad, multidisciplinary field that involves many different teams and processes. Before a product reaches the shelf, it undergoes years of research, product development and formulation, safety testing, quality control, manufacturing, and marketing.

Ultimately, cosmetic science teams work to create products that are not only in demand and enjoyable for customers to use but, most importantly, safe and effective.

The Federal Food, Drug, and Cosmetic Act (FD&C Act) defines a cosmetic as any substance that is applied to the surface of the human body to cleanse, beautify, or protect appearance. Under this law, a cosmetic cannot alter a body’s structure or function in any way.

Some, but not all, of the cosmetic categories listed by the FDA include:

• Makeup
• Fragrance
• Hair care
• Nail care
• Skin care
• Oral care 
• Deodorants
• Shaving products
• Sunscreen

Although cosmetic science and cosmetology sound similar, they are two distinct fields.

A cosmetologist works directly with clients in settings like hair and nail salons and spas. They specialize in makeup, beauty, hair, skin, and nails and must receive a state license from a beauty school before practicing.

Cosmetic scientists, on the other hand, specialize in researching, developing, formulating, testing, and manufacturing cosmetic products. To work in this profession, you need a strong background in science and, at minimum, a bachelor’s degree in a science-related field.  

Cosmetic science is a unique field that blends beauty and art with cutting-edge technology and multiple scientific disciplines, including:

• Chemistry
• Biology & Physiology
• Materials Science
• Chemical Engineering
• Toxicology
• Microbiology
• Consumer Science

Cosmetic scientists need a solid understanding of cosmetic chemistry to handle and mix raw materials and to test cosmetic formulations for quality. Knowing biology and human anatomy, especially hair and skin, also allows scientists to predict how ingredients will affect individuals.

Training in toxicology also lets scientists check whether chemicals are safe, and microbiology helps keep products shelf-stable and free from harmful bacteria.

Whether you work for a new indie makeup company or a beauty conglomerate with dozens of brands, cosmetic scientists apply their unique skills and scientific expertise to different stages of the cosmetic formulation process.

Some of the most common areas that cosmetic scientists work in include:

1. Research and Development
2. Formulation and Testing
3. Clinical and Consumer Evaluations
4. Safety and Regulation
5. Manufacturing 

In this early stage, a cosmetic scientist approaches the drawing board to brainstorm a new product's details. They might set goals for the new product, research customer needs and market demand, and explore potential ingredients and formulations before taking their plans to the research and development (R&D) lab.

According to Crown Abbey, an international cosmetics R&D firm, initial concept research and development can take 3 to 4 months, though innovative products with new ingredients may take much longer.

Cosmetic scientists specializing in formulation and testing work in labs to turn product plans into a reality. They use materials such as emulsifiers, preservatives, active ingredients, stabilizers, and fragrances to develop and troubleshoot cosmetic formulations. This step can take anywhere from 3 months to over a year.

Testing and clinical trials are also important because they determine whether formulations are safe, stable, effective, and meet the product's intended claims. Feedback from these tests and trials usually leads to further refinement until the company achieves a successful formulation. 

Unlike drugs and medical devices, cosmetic products made and imported into the U.S. do not need FDA approval before they are sold on the market, unless they contain color additives. However, that does not mean that cosmetic scientists do not oversee rigorous safety and regulatory checks on new products.

Under frameworks like the FD&C Act, the Modernization of Cosmetics Regulation Act (MoCRA), and the Fair Packaging and Labeling Act, cosmetic scientists must ensure that all products:

1. Are safe for use
2. Are properly and accurately labeled
3. Are not contaminated
4. Only contain claims that are scientifically justified

If a product fails to meet these standards, companies are legally responsible. Therefore, cosmetic scientists must gather and maintain robust safety data sheets on their products, their ingredients, scientific claims, and clinical testing.

Cosmetic scientists are also involved in manufacturing, especially when transitioning a product from lab development to full-scale production. According to Cosmeta, some of the work cosmetic scientists undertake in this process includes:

• Writing manufacturing procedures
• Selecting manufacturing-friendly ingredients
• Supporting pilot batches
• Troubleshooting issues with production supervisors

The global cosmetics industry is a thriving and competitive market, estimated to grow from $375 billion in 2026 to over a trillion by the mid 2030s. Cosmetic science professionals are needed across many different areas and specializations.

According to the Society for Cosmetic Science, some top career pathways in cosmetic science include:

• Research and development
• Clinical and consumer testing
• Product, process, and packaging development
• Manufacturing
• Quality control and assurance
• Product evaluation and safety testing
• Microbiology
• Sales and marketing
• Purchasing

The job outlook for cosmetic scientists is also strong, with the Bureau of Labor Statistics predicting 7% employment growth for chemists and materials scientists and an average annual wage of $91,240.

To begin a career in cosmetic science, an undergraduate degree in chemistry, pharmaceutical sciences, chemical engineering, or biochemistry is the industry standard and serves as a strong starting point. For some individuals, these degrees provide the technical and scientific principles needed to secure an entry-level position.

However, many companies require cosmetic scientists to have graduate degrees in cosmetic science, significant laboratory experience, publications, and direct industry experience. A master’s degree in cosmetic science provides advanced industry knowledge, qualifications, and skills that can help you earn a position at leading companies and stand out in a competitive job market.

Globally recognized as one of the country’s oldest cosmetic science programs, UC’s online Master of Science in Cosmetic Science prepares students with the skills and knowledge to advance their careers in cosmetics and personal care.

Led by renowned faculty within the James L. Winkle College of Pharmacy—one of the top 40 pharmacy colleges in the country—our innovative coursework teaches students how to appropriately use raw materials to make new products and then develop, formulate, and assess the safety and quality of the products for human use.

Students in our program gain an international network while completing their entire degree online with part-time flexibility. Our students and faculty have built careers with some of the most notable brands in professional and personal care, including:

• L’Oréal
