Enjoying the mask too much? Leaving it on for a longer period doesn't necessarily yield better results. (They don't just put the 20-minute mark in the instructions for fun.)

Your sheet mask will dry out soon after the recommended duration, which can actually strip moisture and nourishment away from your complexion. So always follow the instructions (okay, maybe exceeding just a FEW more minutes is alright). If you really want to keep it on longer, you might want to try an overnight sleeping pack instead.

Moisturizing after the mask session will seal in the works of your sheet mask and further hydrate your skin, leaving your face supple and glowing.

Okay, so what about toner?

Well, it depends on the type of mask you're using. For sheet and sleeping masks, you've got apply it beforehand, since it'll help prep your skin. For peel-off masks, you should use the toner after, as it helps remove the residue of the product.

Rinsing your face after a sheet mask is money and effort down the drain: You're basically washing off all the good stuff! You need to let your skin absorb all the nutrients to get all the nourishment you need. Give the essence time to settle into your skin. This usually takes around ten minutes — then it's time for moisturizer.

Pro tip: Don't throw away the sheet mask packaging right away — because it's full of extra essence. Instead of throwing it away, why not apply it to the rest of your body? Your hands and neck surely need some skin care loving too! You can also transfer all the liquid to a sealed container and use it with cotton pads in the future.
