Peels and Concentrations
You might have heard or seen certain percentages used in conduction with peels: Glycolic Acid 20% or 30%, for example. These denote the concentration of the key ingredient (Alpha-Hydroxy in the case of this example) in the peel’s chemical make-up.
According to Dr Bradley Wagemaker, “The actual chemicals used and the way the entire chemical cocktail is combined in the product plays a huge part in the strength and effectiveness of the peel,” he says. “So you’ll find that a 15% concentration in the same type of peel from two different sources might not be equally effective.”
Another important factor is the person performing the treatment: a skincare therapist or medical aesthetic doctor who is trained and well versed in the particular protocols of a product.
