Frequently Asked Questions

How long can my child use the Maxi-Cosi Kani?

The Kani is designed to serve your child from birth through approximately 10 years of age, spanning four distinct modes. It starts as a rear-facing seat for infants and transitions all the way to a backless booster for children up to 45 kg (100 lbs).

Can the Kani fit three-across in my vehicle?

Yes. The Kani features an ultra-slim profile specifically engineered to allow three car seats across the back seat of most vehicles. Actual fit may vary depending on your vehicle's interior dimensions.

How do I convert the Kani to backless booster mode?

An intuitive one-hand release mechanism lets you detach the seat back in seconds, instantly converting the Kani into a lightweight backless booster without tools or complicated steps.

returned- for now
Style: Updated Formula
I was using the lotion version of this for about a year, then went to the balm for more hydration. However, it seems to be breaking me out. I think because it's spring, im not needing as much occlusion as i did during winter. I'm gonna go back to the lotion formula, then pick this up again next winter. It is a little hard to spread, but I spray the avene mineral water on, let it dry slightly, and press the balm into my skin when its still wet. That helps thin the balm just enough to rub in. Otherwise, it can actually feel kind of rough!

Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!
