Product is great! Is hydrating, but not enough on its own if you have very dry skin or live in a dry climate, so still need a hydrating moisturizer too.

I’ve struggled with very dry, easily irritated skin, and my dermatologist recommended Serum Bleu to me. Within just a few days, I started noticing a real difference, my skin felt much less irritated and significantly less dry. I’m hooked! Thank you, Cible Skin, and thank you, Dr. Gerstner, for recommending it to me!

I have been using Sérum Bleu for a long time, and it has become my favorite hydrating serum. Before using it, my cheeks used to get extremely dry every winter, and I would often notice dry, flaky patches on my skin.

After using it for about a month, I could really feel that the dryness had improved. My skin felt more comfortable, smoother, and better hydrated. What I also like is that it absorbs quickly into my skin and never feels sticky or heavy.

Now I use it every day, especially when my skin feels dry or needs extra comfort.

I use Cible Skin Sérum Bleu every single day, and it is a game‑changer for office‑based skin concerns. Long hours sitting under office air conditioning used to leave my skin stiff, flaky and dehydrated by midday. This serum offers phenomenal instant hydration with reliable 8‑hour moisture retention, keeping my skin plump all workday. It reinforces the skin barrier, dulls oxidative dullness caused by stale indoor air, and gently relieves dryness‑triggered redness. The lightweight blue serum absorbs quickly with zero sticky residue. I will keep repurchasing and highly recommend it to office workers struggling with air‑conditioning damaged dehydrated skin!

I’ve been using Sérum Bleu for years and really enjoy it. It absorbs incredibly fast, so I can layer it with almost any other skincare product without pilling. The hydration doesn’t come from a greasy finish—it feels like my skin is actually absorbing water from within. My skin stays comfortable, looks healthier, and feels more balanced throughout the day. I’ll definitely keep using it.

Customer (France)

I use this serum for its antioxidant benefits, as vitamin C products tend to feel too heavy on my skin. It keeps my skin hydrated, gives it a healthy glow, and makes it look more plump. I’ve also noticed that the dehydration lines on my forehead are less visible.

There is the water and there is the blue serum…It’s the product that hydrates my skin, calms it down, and at the same time gives me a beautiful complexion.
