Whether your mask is homemade or store-bought, here are six general tips to stick to when pampering your skin. The one caveat to mention here is with enzyme masks. Since these exfoliators become more powerful with increased temperature (even small changes in temperature, like one or two degrees, can increase efficacy by 10% to 20%, according to research!), slathering them on in the shower as opposed to post-rinse can amplify their effects. Just make sure the mask is slightly chilled, as a freezing sensation can shock the skin and potentially cause broken capillaries. A few minutes (like, say, the length of your shower) should do the trick. Not only will using a brush to apply a mask guarantee that most of the product ends up on your face (and not on your palms/fingers/floor), it’ll also ensure even application over your face—it’s much easier to control how much product you pick up and lay down on your skin. That’s not to say you absolutely have to use a brush—your fingers are just fine!—but if you’re looking for a mess-free, elevated experience, they can help. Just remember to wash the brush after every use and make sure it’s dry before storing. But let’s say you skip the clay mask and stick to a thin, jelly goop. Are you A-OK? Well, if the confection contains exfoliating actives, you may run the risk of said ingredients getting a little too active with your skin and, again, run the risk of irritation. As a general rule: Don’t leave the mask on for longer than the recommended time on the packaging, and remove immediately if you think you may be facing a reaction. Extreme temperatures either way can also cause broken capillaries for those with sensitive skin, so opt for room temperature water when it comes to removing a mask. You can also use a gentle, clean cloth (like a muslin cloth) for some extra help if necessary.
