What is the maximum pH level for exfoliation products used by a Master Esthetician?

The maximum pH level for exfoliation products, particularly those utilized by a Master Esthetician, should be around 4.0. This is important because pH levels significantly affect the effectiveness of exfoliation products. Products with lower pH levels, such as 1.0 or 2.0, can lead to a more intense exfoliation but also carry a higher risk of irritation and adverse reactions for clients with sensitive skin. A pH level of 3.0 is still within a range that may be used, but it is not the optimal maximum limit for safe professional use.

Thus, maintaining the maximum pH level at 4.0 ensures efficacy while minimizing potential skin irritation, allowing for professional-grade exfoliation that enhances skin texture and appearance safely.
