PEELS. About pH and Buffering
First, keep in mind this sentence:
“In the aesthetics industry Research and Development timelines don’t generally go well with marketing timelines and customer aspirations”
“How corrosive an acid or a base is does not relate to its strength or percentage in the solution.”
The concentration of acids in the solution and pH are not the only factors in determining the strength of a peel. A chemistry law that largely unspoken of in marketing brochures but which is inherent to all molecules determines the relative strength of all acids or bases is what known as the pKa value.
“The higher the pKa value, the weaker the acid. The lower the pKa value the stronger the acid”
pKa values are fixed and constant for every molecule, it never changes no matter what the concentration of the molecule in a solution, no matter what the pH of a solution is
The efficacy it depends not only on the structure and size of the molecules, their concentration, and the pKa of each molecule and the pH of the global formulation is also a question of balance and respect of chemistry rules.
Skin proteins are complex chains of amino acids and they are very sensitive to the level of pH surrounding them. When the skin’s proteins react with an acid in low pH coagulation occurs. This is a non-reversible reaction where the proteins are basically destroyed.
If the pH is chemically altered to give a higher pH, the reaction is slower and the coagulation is less than it would be if the peel were un buffered, this allow you to keep this on your skin without feeling a constant irritation while still benefiting from the acid.
Buffering can either increase or decrease a pH level when mixing chemicals. Buffered and non buffered products can carry the same percentage of an active ingredient, but the strength of the ingredient will vary greatly.
