It's best to wait until your cold sore scab has fallen off and the skin behind it has completely healed before coming in for a facial. The movements of the facial massage can aggravate the lesion or even spread it to the eye area, which can be dangerous. To avoid any risk, our aesthetic therapists follow these specific guidelines. If you currently have a cold sore, we recommend that you continue your home care routine and increase your hydration until your skin is ready for your next treatment.
