'It's a facial in a packet' - Sienna Miller just persuaded me to try Charlotte Tilbury's Instant Magic Mask

I'm shopping Sienna Miller's £18 'hydrating' face mask to combat my dry winter skin - she just revealed that the reusable Instant Magic Mask by Charlotte Tilbury is her 'skincare secret' to getting a 'glass skin' look.

Sienna Miller has convinced us here at woman&home to try out a lot of different skincare products and, since we've fallen in love with them all upon trying them out, of course I'm going to buy the face mask that she's just revealed she uses to get a hit of 'hydration' before putting on her makeup.

"Hi everyone, it's Sienna Miller - I promise," the celebrity joked in a video posted to Charlotte Tilbury's social media as she appeared in an almost jump-scare like way with Charlotte Tilbury's Instant Magic Mask already plastered across her skin.

"I am using Charlotte's Instant Magic Facial Dry Sheet Mask which is a facial in a packet - and you can use it more than once which I love," Sienna explained as she began to gently press her fingers across the mask and her skin. "I'm just pressing it in to active it," she said. "But it's doing its thing, I can feel it."

Its 'thing' is to hydrate skin while also smoothing and firming the complexion, with niacinamide, floral extracts, butters and oils working in harmony to nourish and boost radiance. Simply cleanse your skin and then put it on to 'get facialist worthy results in 15 minutes,' Charlotte Tilbury's website says.

Even in the video, the quality of the reusable sheet mask is clear to see, with its thick fabric looking nothing like the usual slippery sheet masks we're used to seeing. This high-quality is why the mask can be re-used up to three times, meaning each pamper session only sets you back £6, with the mask holding in the skin-loving serum over time for a drip-free finish that's comfortable and easy to move around in thanks to the ear loops that hold it in place.

"There we are," she said pulling the mask off. "[I'm] very hydrated and glassy-skinned and ready for my nighttime look."

Sienna isn't the only person who loves the product, shoppers are raving about it too. "I have been surprised by the positive results achieved after using this Dry Sheet Mask," one reviewer wrote, adding, "From first use skin seems firm and deeply nourished."

Another shared, "Super hydrating and leaves you with the most amazing glow. Great value for money and really practical to wear while you're getting ready - no drips!"

And one skeptical shopper wrote, "This mask really surprised me. I took it out and it's like a piece of dry cotton, so I didn't see how it would work. After I removed it, there was definitely a serum like film on my skin which really surprised me! It was a nice pick me up for my skin which was pretty dewy and refreshed after."
