If a client does not feel stinging from the exfoliating serum, what does this indicate?

If a client does not feel stinging from the exfoliating serum, this typically indicates that the product is not strong enough to effectively remove dead skin cells or boost cellular turnover. Exfoliating serums are designed to stimulate and work at the level of the skin where exfoliation occurs, and a mild or ineffective product may not trigger the desired sensations that often accompany an active exfoliation process.

While irritation or an overly strong formulation would typically present as discomfort or a burning sensation, the absence of stinging suggests that the active ingredients may not be sufficiently concentrated to produce noticeable results in terms of exfoliation. Therefore, when a client does not feel any stinging, it can signal the need for a more potent formulation to achieve desired outcomes, such as brighter skin and improved texture.
