pH and Buffering in Peels
Science Behind Beauty: pH and Buffering in peels
In this section, you will discover the scientific foundations that underpin the genuine efficacy of our peels, designed with precision and integrity in our Teiá, Catalunya laboratory. Our formulations are grounded in rigorous research and adhere strictly to established chemical principles, ensuring that our products deliver realistic and safe results without resorting to exaggerated claims or misleading promises. Science behind beauty: pH and buffering in peels.
Understanding pH, pKa, and Buffering
It is essential to understand that «the corrosiveness of an acid or a base does not directly correlate with its concentration in the solution.» In the aesthetics industry, research and development timelines do not always align with marketing schedules and customer aspirations. Therefore, our products rely on solid scientific principles rather than ephemeral trends.
The Role of pKa in Efficacy
The pKa value is a fixed constant for each molecule, defining the relative strength of an acid. A higher pKa indicates a weaker acid, while a lower pKa signifies a stronger acid. This principle is fundamental in illustrating that the concentration of acids and the pH of the solution are not the sole determinants of a peel’s intensity. The efficacy of each product depends on the molecular structure, size, and concentration, as well as the precise balance between the pKa of the active components and the overall pH of the formulation.
Buffering: Achieving the Ideal Balance
Buffering is the process used to adjust the pH of a formulation, thereby preventing undesirable reactions. Skin proteins are complex chains of amino acids that are highly sensitive to pH changes. When exposed to a low pH environment, these proteins may undergo irreversible coagulation, resulting in their destruction. By employing an effective buffering system, the pH is gently elevated, reducing the rate of reaction and minimizing protein coagulation. This approach allows the peel to work effectively while minimizing any constant irritation, thereby maintaining skin integrity and ensuring visible benefits.
