Ultra-light texture that absorbs in seconds, no greasy residue. I apply it before my slimming cream morning and evening and after 3 weeks my skin is noticeably firmer on my tummy. I'm on my 2nd bottle.

The first step, before the cream

A light texture that melts into the skin
Its light and silky texture melts instantly into the skin, with fast absorption and no residue: you can get dressed straight away. A soft fragrance accompanies the ritual, and the bottle fits in a bag. Applied before the cream, the serum makes the massage more pleasant and leaves the skin supple and comfortable.

The one that changed my whole routine
Right, a bit of context: since working from home I've been moving around a lot less and I've noticed my figure changing, especially around my tummy and inner thighs. I already had the cryo cream but I was plateauing a bit with the results. I added the serum in October on the advice of a colleague who was already using it. I apply it morning and evening just before my cream, and honestly the texture is perfect — it glides really nicely on the skin and absorbs in under 30 seconds, no greasy film, I can get dressed straight away. After 3 weeks I could feel my thighs were firmer to the touch, and at 6 weeks I compared my before/after photos and the difference is clear: my tummy is smoother and the dimples on my thighs have really faded. I'm on my 3rd bottle now — it's become an absolute essential. Better than anything I'd bought at the chemist before.

Fine but not enough on its own
I bought the serum hoping for a real boost on my thighs. The texture is nice, it's true — absorbs quickly and smells pretty good. My skin is a bit softer after a month and a half of using it on its own, but in terms of cellulite I haven't seen any noticeable change. Apparently you need to combine it with a cream for it to work better, but that means extra cost I hadn't budgeted for. The 150ml bottle also runs out pretty fast when you're using it twice a day on several areas. I'm not totally convinced — I'll finish the bottle with a cream this time and see if that makes a difference.
Answer: Cellublue
Bonjour Charlotte, vous avez la réponse : le sérum est le premier geste d'une routine, pas un produit autonome. Il prépare la peau et la laisse lisse et souple ; c'est le gel ou la crème appliqué juste après qui travaille l'aspect de la peau. Ajoutez ce second temps, matin et soir.

The turning point in my slimming routine
Right I'll try not to write a novel but I've got so much to say about this serum!! After my divorce last year I put on quite a bit of weight, especially around my belly and hips. I already had the Cellublue slimming cream but results were plateauing a bit. I added the serum as the first step in my routine, morning and evening after my shower. The texture is amazing, ultra-light, sinks in within seconds and leaves skin silky. No greasy film, no need to wait 10 mins before getting dressed. The scent is fresh and subtle, I love it. After 2 and a half weeks I felt my skin much firmer around my belly, and at 5 weeks I'd lost 3cm off my waist. But the real thing is it really boosts the effect of the cream I apply after, it's like an accelerator. My sports coach congratulated me on my progress even though I only do 2 sessions a week. I've just finished my first bottle and already bought another, it's non-negotiable in my routine now.

Great texture but slow results for me
I'll be transparent because I think it's important to have balanced reviews. On the product quality itself there's nothing to fault: the texture is really nice, very light, sinks in super fast and skin is soft and smooth right after application. The formula is clean, almost 100% natural, that's a big plus for me who cares about what I put on my skin. But results-wise on my thighs it was really slow. I applied religiously morning and evening for almost 4 weeks before starting to feel a difference to the touch. I've had cellulite since my teens so I think that's linked to it. The 150ml bottle runs out quite quickly when you use it twice a day on multiple areas. Despite all that I'm continuing because from week 5 onwards I'm really seeing it shift, my skin is firmer on my inner thighs. I just think you can't expect results in 15 days like some people claim.
Answer: CellublueBonjour Katy, un avis nuancé nous est plus utile qu'un avis enthousiaste. Le sérum est le premier geste d'une routine : seul, il laisse la peau lisse et souple, mais c'est la crème ou le gel appliqué juste après qui complète l'action. Vérifiez que cet enchaînement est bien respecté, matin et soir.

Finally found my secret to a flatter belly!
Girls honestly I'm coming to tell you about my experience because I'm so happy!! So right, after my second pregnancy I couldn't get rid of my little belly and love handles. I'd tried everything: £40 creams from the pharmacy, manual massage rolling for hours in front of Netflix... basically nothing worked.
I started the serum in early December, I apply it morning and night before my cryo cream. The texture is INCREDIBLE, it sinks in straight away without being greasy and smells amazing (not that chemical stuff we usually get). After 3 weeks I started feeling my skin firmer, like when you pinch it there's less sagging if you know what I mean.
Now it's been 2 months and honestly the results are there: -4cm waist circumference, my belly is really smoother and my high-waisted jeans fit better!! My boyfriend even said "have you lost weight?" without me mentioning it. The thing is it really boosts the effect of the creams you apply after, I should've got it from the start.
If you're hesitating go for it, honestly for the price it's worth it and the formula is clean. I've just ordered a second one ;)

Good product but you need to be patient
So I'm going to be honest, the product is really well made: super pleasant texture that sinks in quickly, delicate scent, skin is lovely and soft afterwards and the formula is natural which matters to me.
I've been using it for 5 weeks now morning and night before my night cream, and honestly it's a pleasure to apply, it glides well and isn't sticky at all.
But... I waited almost 3 weeks before seeing any result, and at first I was a bit disappointed because I expected something faster given all the positive reviews. Like the first two weeks I was thinking "well it's not working on me" and I was ready to give up.
But actually now that I'm persevering I'm starting to feel my skin firmer on my thighs and my belly is a bit smoother. So I'm continuing because I can see it's starting to work, but yeah you really need to be patient and not expect miracles in a week.
I think it depends on the person and the type of cellulite. For me it's quite old so it's normal it takes longer. I'm giving 3 stars for the timeframe but I'll buy it again anyway!
Answer: CellublueBonjour Nadège, cinq semaines d'application matin et soir, c'est le rythme qui convient à ce sérum aux cinq algues marines. Un point à vérifier : il s'utilise en premier geste, avant la crème de nuit, jamais après. Ce qu'il apporte, une peau lisse, souple et tonifiée au toucher, se juge sur la durée.

The booster my routine was missing
Ultra-light texture, it sinks in within seconds. I apply it before my slimming cream and in 3 weeks my skin is visibly smoother on my thighs. I'm on my 2nd bottle now, I can't do without it anymore.

Good but you have to be consistent
The texture is great, smells nice and the formula is clean, nothing to complain about there. That said, you really have to use it morning AND night for at least 3 weeks to start seeing something. The first few weeks I nearly gave up. Now I can see movement on my belly, so I'm carrying on.
Answer: CellublueBonjour Emmanuelle, vous avez identifié la règle : matin et soir, sans exception, pendant au moins trois semaines. Le sérum est un préparateur, il ne remplace pas le soin minceur qui vient ensuite. Continuez sur le ventre, en massage circulaire jusqu'à pénétration complète.
