A: It is normal for treatments to result in some skin irritation, especially for clients with more sensitive skin. Always wait a minimum of 90 minutes before putting anything else on the skin. During this time it is normal for the skin to remain pink or light red. After the 90 minutes you can apply additional moisturizer or other products. Keep in mind however, that as your skin may be more sensitive than usual for several days after the treatment, especially strong topicals should be avoided until the skin returns to normal.
