Frequently Asked Questions
How soon will I see results?
You'll notice an instant glow and hydration after your first use. Brighter skin appears within the first week, while firming and anti-aging benefits develop over 2-3 weeks of regular use.
How do I use it?
Apply it as the last step of your nighttime routine. Use the included spatula to spread an even layer, avoiding eyes and lips. Wait 15 minutes to dry, then sleep. Peel off gently in the morning.
Is this safe for sensitive skin?
Yes. It's dermatologist-tested and formulated with calming ingredients like Centella Asiatica. Free from parabens, sulfates, harsh alcohols, and fragrances that can irritate skin.
Will it transfer to my pillow?
No. Once dry, the mask creates a protective seal that stays put all night without transferring to bedding.
How often should I use it?
Use 2-3 times per week for best results. You can use it more frequently during dry weather or when your skin needs extra hydration.
Do I need to rinse it off in the morning?
No. Just peel it off gently from the edges. It comes off cleanly in one piece. You can rinse with water if you prefer, but it's not necessary.
How is this different from other overnight masks?
It creates a protective seal that locks in your skincare while delivering advanced anti-aging actives like Copper Tripeptide-1 for real firming results—not just surface hydration.
What if I'm a side sleeper?
The mask is designed to stay intact even for side sleepers. It won't rip or transfer, so your skincare stays on your face instead of your pillowcase.
Where does this fit in my skincare routine?
Use it as the final step after cleansing, toning, serums, and moisturizer. It seals everything in and maximizes absorption.
Can I use this with my other skincare products?
Yes. It's designed to work with your existing routine and actually enhances the effectiveness of your other products by sealing them in.
What's included?
Each package includes a 100ml tube and a professional application spatula.
Who is this for?
Anyone looking for deep hydration, firming, and anti-aging benefits. Perfect for dry or sensitive skin, side sleepers, and those who want glass skin results without messy products.
What if I don't like it?
We offer a 30-day money-back guarantee on unopened and unused products. Contact us for a full refund if you're not satisfied.
