BOTOX® and Restylane are injections, so treatment is accompanied by a pricking sensation. We can apply a topical numbing cream, and dermal fillers like Restylane contain lidocaine to minimize your discomfort. Depending on the depth of the needling needed during The Eraser treatment you may feel anything from a slight sensation to more significant pricking – again, a numbing cream can be applied to minimize discomfort. Non-invasive Ultherapy and ThermiSmooth are completely pain-free treatments.
