Why is it essential to avoid using multiple strong active ingredients simultaneously?

Avoiding the simultaneous use of multiple strong active ingredients is essential primarily because it can irritate the skin and increase sensitivity. When strong active ingredients, such as retinoids, alpha hydroxy acids (AHAs), or beta hydroxy acids (BHAs), are used together, they can disrupt the skin barrier, leading to conditions like redness, peeling, and dryness. This irritation occurs because each active ingredient exerts a strong effect on the skin, and their combined impact can overwhelm the skin's natural processes.

When the skin barrier is compromised, the risk of adverse reactions heightens, making it crucial for practitioners and clients to be aware of how these ingredients react with one another. This practice helps in maintaining a balanced approach to skincare, ensuring that the skin can tolerate the treatments without experiencing negative side effects. Understanding ingredient interactions aids in creating a more effective and targeted skincare regimen tailored to the individual's needs.
