What is the last basic step involved in developing a new skin care product?

In developing a new skincare product, the final basic step is marketing. This stage is crucial as it involves creating a strategy to promote the product to the target audience. Effective marketing encompasses various tactics, such as advertising, branding, and positioning the product in a way that highlights its benefits and appeals to consumers. It ensures that potential customers are aware of the product's existence and understand its value proposition.

The preceding steps in the development process, such as formulation and testing, focus on creating the product itself and ensuring its safety and efficacy. After these steps are completed, marketing becomes essential to drive sales and engage customers. Therefore, after the formulation and testing phases, launching the product into the market through effective marketing strategies is what ultimately leads to its success.
