Balance, Brighten and Hydrate for a Dewy, Even Glow
Rather like a long, cool drink for your skin, this antioxidant-rich serum does what it says on the tin, albeit in a way that feels rather marvellous. Light, fragrance-free and utterly forgiving, it layers into your routine without fuss while doing the heavy lifting for balance, hydration and brightness. Even temperamental skin stays happy.
Why Choose Our Replenish Serum
Oil-Free Hydration: A weightless formula that absorbs in moments, leaving skin plumped and soothed without any greasy residue. Think of it as the skincare equivalent of showing up on time and not overstaying your welcome.
Clinically Proven Actives: Niacinamide refines tone and minimises pores while guarding against free radicals. Triple-weight hyaluronic acid holds moisture at every skin layer. Ectoin and Glycoin, both plant-derived powerhouses, boost hydration and support barrier health to prevent pigmentation.
For All Skin Types: Particularly splendid for sensitive, hormonal or blemish-prone skin. This serum calms without irritation, helping refine texture while keeping your barrier happy and resilient.
Social Proof: Margaret H reports her skin feels nourished, hydrated and the best it has looked and felt in years. It is, quite frankly, a joy to use.
Product Details
Format: Cool, weightless and refreshing. Glides on effortlessly and absorbs fast.
Per Bottle: Approximately 180 applications from a 50ml bottle. That is rather good value for twice-daily devotion.
Certifications: Vegan, certified cruelty-free and palm oil-free. Handmade fresh in the UK.
How to Use: After cleansing, press 2 pumps into your face and neck. Follow with your moisturiser and optional radiance booster. If you use retinols or exfoliating acids, Replenish becomes your best ally against dryness and irritation while keeping everything beautifully balanced.
This is the serum Margaret H wished she had found years ago. Rather a good time to discover it yourself.
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.

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.
