According to Skin Body Soul Spa, a salon in Iowa that offers HydraFacials, there's a whole list of dos and don'ts following the treatment beyond avoiding harmful skincare products. In their post-care instruction manual, they advise customers to wear sunscreen at all times and warn against going in the sun for 72 hours. They also say that you need to stay away from the gym, hot showers, and saunas for the first 24 hours after treatment. While you can wear makeup immediately after a HydraFacial if you want to, you're best leaving your skin to breathe for as long as possible, even if it's just for the rest of the day. 

Lastly, postpone your next wax if it falls to close to your HydraFacial appointment. "Waxing especially exfoliates the skin, and over-exfoliation will make it more likely that the wax will lift the skin and leave you with an ugly scab instead of beautifully groomed brows," Chicago-based aesthetician Meghana Prasad explained to SELF.
