Pickup currently not available
For Skin That Looks Utterly Fabulous (and Slightly Smug)
If your body feels more crumply than crisp lately, this gloriously clever serum is just the ticket. Packed with sea botanicals and plant extracts, it coaxes skin into behaving like its younger, better-hydrated self. Think less 'wilting lettuce', more 'champagne on a summer lawn'.
Why Choose Our Firming Algae Body Serum?
Cellulite Reduction: Organic horse chestnut and ginkgo leaf improve circulation, giving dimples a run for their money. It’s basically diplomacy for your thighs.
Firmer, Fresher Skin: Infused with cranberry extract and cornflower water full of vitamin C and salicylic acid, it gives you that radiant, 'I definitely do yoga' glow—even if you very much don't.
Deep Hydration: Mineral-rich rockweed seaweed hydrates your skin with the tenacity of a hopeless romantic. Goodbye dryness, hello glorious smoothness.
Product Details:
Formula: COSMOS Organic Certified for extra peace of mind and general smugness.
Free From: No parabens, sulfates, silicones or EU-listed allergens. Nothing ghastly, in other words.
Ethics: Vegan, cruelty-free and made with minimal ingredients—but maximum panache.
Application
Massage morning and evening into the bits needing a little... support: arms, tummy, hips, bum (terribly sorry), thighs and knees. Pair with our anti-cellulite cream for truly marvellous results. Rather like showing up for a run without actually running.
Your skin’s future is looking fabulously firm. Might be best to get started now, before everyone else catches on.
SHIPPING + RETURNS
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!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us

We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
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.
