What is the main focus of hydroxy acid formulations?

The main focus of hydroxy acid formulations is indeed centered around the base of the formula, percentage, and pH. Hydroxy acids, such as alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), are used primarily for their exfoliating properties in skincare products. The effectiveness and safety of these formulations largely depend on their specific composition, particularly the concentration of the active ingredient and the pH level of the product.

The base of the formula is critical as it determines the stability and skin compatibility of the acids. A well-formulated product will have a balanced formula that enhances the efficacy of the acids while minimizing irritation. The percentage concentration of the hydroxy acids directly influences their strength and the desired exfoliation effects. Additionally, the pH level is essential because it impacts the acid's ability to penetrate the skin. An optimal pH allows for effective exfoliation while maintaining skin health, which is essential for results.

In contrast, other considerations such as cost efficiency, packaging, marketing, color, scent, texture, application techniques, and aftercare play supportive roles in product development and user experience but do not directly focus on the therapeutic efficacy of hydroxy acid formulations.
