If a client does not feel stinging from an exfoliating serum, what does it imply?

When a client does not feel stinging from an exfoliating serum, it suggests that the serum is not strong enough. Stinging or a tingling sensation is often expected with more potent exfoliating agents, particularly those containing acids like glycolic or salicylic acid. These sensations indicate that the product is actively working to exfoliate the skin.

If a client experiences no sensation, it may mean that the concentration of the active ingredients is insufficient to elicit such a response, signaling that the product might not be effective for their skin type or condition. As a result, practitioners may consider evaluating the formulation or strength of the serum for future use to ensure it meets the client's skincare needs.
