Significantly Smarter...
ProIsoCharge delivers digitally controlled alternator output distribution while protecting the health of engine start batteries. An industry changing design that provides intelligent and zero voltage loss isolation, charging of up to 3 other battery banks off a single alternator (model specific). For dual engine applications, ProIsoCharge offers an exclusive 2 alternator input model with up to 4 battery banks. Smart enough to provide priority charging to a battery bank that's under load by taking fully charged batteries off line. The all-in-one design eliminates the need for multiple voltage sensitive relays to charge multiple battery banks simultaneously, saving space, installation time and cost. Ensuring fully charged batteries and faster charge times, ProIsocharge eliminates the typical alternator voltage loss of 0.6VDC that's commonly associated with traditional diode based isolators. Installed with the ProNauticP Series, a boat owner can enjoy the full benefit of shore power and on the water charging. Designed to provide more time on the water enjoying what you like most... boating.

A rich moisturizer that doesn’t feel heavy!
Size: 13.5 Ounce (Pack of 1)
I bought this because the skin on my face is very reactive and has also been very dry and I wanted to try something that was a little more rich than the moisturizer I was using. I liked that this is for face and body so it comes in a bigger size than typical face moisturizers come in. I have been using it for about a week and have noticed a reduction in flakiness and my sensitive skin does not get irritated by it. It absorbs really well and doesn’t feel heavy or make my skin feel sticky. I definitely feel it is worth the price since you get so much in the bottle and it will last a very long time!

The best eczema cream I’ve used !!!
Size: 6.76 Ounce (Pack of 1)
I will give 10 stars if it were available!! Used most of the eczema creams out there, including prescribed ointments, but given the fact you can’t avoid using water on your hands throughout the day, the eczema was only getting worse for the past couple of months! I am glad I didn’t give up and found this cream!!! The second I put this cream on my hands, it immediately moisturized the itching and flaking skin without drying or being greasy unlike other creams I’ve used before. It’s very calming, soothing, and deeply moisturizing! So I had to write this review for those who are suffering the similar symptoms. This may help you as much as it is helping me as I speak!

Seems to work for damaged barrier (accidental damage as well as eczema and rosacea).
Size: 6.76 Ounce (Pack of 1)
SO I am currently tryign to repair a damaged skin barrier. I have both rosacea and eczema so it's nearly impossible to find a product that makes both conditions happy. I started out using the cream version of this but my face always felt dry with it. I decided to try this since a balm usually helps keep in moisture much better. I am only using a gentle cleanser and this, planning on adding in a toner at some point. At first I thought I was sent the cream again because this comes out like their cream version but as you rub it to spread, you can tell it has a thicker feel to it. It spreads easily and doesn't tug at my skin. Seems to sink in pretty quickly but it does leave a sticky film until it completely absorbs. I can feel my eyelids stick while waiting. Not sure how long it takes to fully absorb because once it does on my eyelids, I forget. But the stickiness does go away and leaves a soft texture behind. I do find some itching in places I normally get when my skin dislikes an ingredient. But I'm not sure if it's my normal or current damaged barrier. It helps with the dry feeling and I would say I only feel a slight tightness. But so far, the best moisturizer I have used. And I love that there is NO NIACINAMIDE, NO HYALURONIC ACID, no oat, no shea butter, and no cica/centella asiatica. These ingredients wreak havoc on my skin and everybody is adding this to everything. It's been so hard to find a moisturizer.

Works quickly to calm itch
Size: 6.76 Ounce (Pack of 1)
I had an itchy outbreak on the back of my hand the day this product arrived. Perfect timing. Applied Avene and within a short time the itch calmed almost 100%. Slept through the night and this morning, the red rash is about 95% healed. So glad I bought this. Just another old age issue to deal with.

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!
