The cosmetics industry is undergoing a significant shift towards sustainability, natural ingredients, and eco-friendly practices. This chapter explores the challenges and strategies for incorporating natural ingredients into cosmeceutical products, focusing on the emerging trends in green cosmetics. The distinction between natural materials, natural sources, and organic components is crucial in understanding the complexities of formulating with natural ingredients. While the terms “organic” and “natural” lack formal definitions in the cosmetics industry, certifications and regulations provide guidance for manufacturers. Nutricosmetics, a growing trend in green cosmetics, combines the fields of food, pharmaceuticals, and personal hygiene to create beauty supplements. The characteristics of the green consumer, who prioritizes environmental sustainability and safety, are also discussed. Green cosmetics must meet specific criteria, such as reduced raw material usage, biodegradable packaging, and minimized environmental impact.
