Why You Should Never Leave Your Sheet Mask on for Too Long + How to Properly Incorporate Them into Your Skincare Routine

Did you know leaving your sheet mask on for too long can actually cause negative effects on your skin? Did you also know that not all sheet masks are the same; therefore, you cannot use them in the same order each time you do your skincare routine. Furthermore, sheet masks are not a one-and-done step — to maximize the benefits, you need to use your mask in conjunction with other products.

Let’s first take a look at why you should never leave your face mask on for too long. I’ll admit, I didn’t know any better and used to ignore the recommended time frame, leaving my face mask on until all the essence or serum absorbed into my skin. I mean, that sounds about right, right? That leaving on the mask until all the essence or serum absorbed into the skin to get the full benefits of the mask because why would anyone throw away a mask that still has product left on it? Seems like a waste of product, right? Unfortunately, leaving your sheet mask on for too long can cause the now dry sheet to instead suck the moisture out of your skin, causing dry skin and excess sebum production. The moisture and goodness we lovingly poured into our skin with the sheet mask goes away and instead causes negative effects. This is why you should not leave your face mask on for too long. This means you should never, ever, ever sleep with a sheet mask on expecting to wake up with beautiful, glowing skin in the morning. You’ll end up with skin that’s worse than before you even used the mask.

I still tend to leave my sheet masks on a little longer than the recommended time frame simply because I know when I can afford to do so and when I need to take it off. When using a sheet mask, keep in mind that not all parts of your face will absorb the product at the same rate. For me, I find that the first areas of my face to absorb all the product is my cupid’s bow area and then my forehead. I’ll have a sheet mask that’s dry in those areas while the cheek area still has more essence or serum left. Of course, you never want to get to the stage where parts of the mask are drying out. This is a sign you’ve left the mask on for too long and it’s way past the point where you need to remove it. Again, just to reiterate, you need to remove your sheet mask even if there is still product left.

Making sense so far? Now, to further boost the benefits of your sheet mask, you need to use it in conjunction with other products. One sheet mask isn’t going to keep your skin hydrated and moisturized (which are different, by the way! I can do a dedicated post on the difference between the two and why it’s important to do both if you’d like. Just let me know!). A sheet mask shouldn’t be used alone as it’s supposed to be a booster to your skincare, not serve as the main product. I recommend following a Korean skincare routine, which consists of using multiple products to hydrate and moisturize the skin. Typically, the general order with Korean skincare is cleanser, toner, essence, serum/ampoule, eye cream, then face cream/sleeping pack. Of course, this isn’t a set order because different products have different consistencies and formulas even within the same product category and there are also categories such as emulsions, balms, etc. However, the rule of thumb is that lighter, more watery formulas should be applied first and heavier, oilier formulas should be applied last.

Why is this important? Again, not all sheet masks are the same. Some include watery, essence-type formulas, while some have thicker, serum- or emulsion-type formulas. The reason why lighter, watery formulas are applied first is because this helps the skin absorb the products better and the heavier, oil-based formulas are applied last because they help lock in the water-based formulas. Think of your skin like a sponge — it won’t absorb and soak up all the water at once. You need to slowly wet it by giving it a couple squeezes. In that same way, applying a heavy, oil-based cream as your first step in moisturizing won’t allow your skin to fully absorb the product. It will just sit on top of your skin rather than absorb into it. Additionally, applying an oil-based formula first blocks off the water-based products from absorbing into the skin as water and oil do not mix. Therefore, it’s important to realize what type of mask you have in order to use your products in the correct order for your skin to soak in all the benefits.

For the most part, essence-type masks tend to be water-based and emulsion-, serum-, or ampoule-type masks tend to be oil-based. You may see some brands deviate from this, but this general rule should guide you in determining where in your skincare routine you should incorporate your sheet mask. Oh, and you probably already know this, but always apply your skincare on freshly cleansed skin! I typically like to use a foam cleanser, follow up with toner, use a facial mist if I have one on hand, apply my water-based essences, and then continue with the sheet mask and the rest of my skincare routine.

I hope you learned something new today and that this post will help you get the full benefits of your sheet mask going forward! I definitely made mistakes when I first used face masks, so I hope this information will help you all use sheet masks correctly. Let’s get beautiful, glowing skin together!

If you’d like me to share more skincare tips and info, just let me know and I’d be more than happy to do so! I have a couple on my mind such as hydrating vs. moisturizing, navigating the world of Korean skincare (because, let’s be honest, there are so many product categories and exceptions to rules), and maybe a couple different posts focusing on different skincare ingredients. One ingredient post I have in mind is hyaluronic acid and how to properly use it. Please give me feedback on whether or not this is something that you’d find helpful or interesting! Help me help you!

Happy face masking!
