Look Rather Less Like You Haven't Slept in Three Days
Look, we've all been there. Those mornings when the mirror suggests you've recently survived a minor apocalypse, dark circles looking rather like you've gone ten rounds with a particularly aggressive panda. Our Under Eye Collagen Boost Gel Mask is precisely the sort of thing that might, just possibly, help with that. Twenty minutes of applied indulgence, and your under-eye area becomes noticeably brighter, firmer, and altogether more splendid.
Why Choose Our Under Eye Collagen Boost Gel Mask
Genuinely Nourishing Formula: We've packed these masks with collagen, hyaluronic acid, vitamins A, E, C and B5, plus natural peptides. The science is rather solid, if we do say so.
Targets What Actually Bothers You: Fine lines, puffiness, dark circles. The lot. This isn't some half-hearted approach. It's proper, targeted care where you actually need it.
That Marvellous Cooling Sensation: There's something genuinely rather lovely about the soothing effect. Your under-eye area deflates like a disappointed soufflé, only in a good way.
Suitable for Every Skin Type: Whether your skin is dry, oily, sensitive, or temperamental, these masks won't throw a tantrum. They're gentle, effective, and utterly without judgment.
Ethically Made, Obviously: Cruelty-free, vegan-friendly, and free from the sort of harsh chemicals that make one's skin feel rather cross. We're not heathens.
Product Details
What You Get: 10 pairs per pack. Each is single-use, ensuring complete hygiene and maximum effectiveness.
How to Use: Cleanse and dry the area around your eyes. Open the foil package, peel off the plastic liner, and apply the mask carefully under each eye. Leave for 20 minutes for a quick lift, or up to 40 minutes for something rather more intensive. Remove gently and marvel at your rather refreshed reflection.
Ingredients: Collagen, vitamin A, vitamin E, vitamin C, hyaluronic acid, vitamin B5, and purified water. Nothing unnecessary, everything purposeful.
These masks rather work best as part of a regular routine. Use them weekly, and you'll notice a genuine difference in brightness, firmness, and overall under-eye radiance. The sort of thing that makes you look properly awake without requiring an additional three coffees.
Don't let dark circles and tired eyes become your default setting. Treat yourself to the properly nourishing care you deserve. Your under-eye area will be rather grateful indeed.

THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
