7% Ectoin Booster.

"Ectoin is an extremely light antioxidant and skin hydrator. It's a trendy ingredient, but I have to admit, I am finding it to be a great ingredient in moisturizing products, and it may help in defending against oxidative stress that contributes to some of the visible signs of skin aging. This far and away was my all-time favorite ectoin product. But oh my goodness, was it ever painful to buy this because it is so expensive at baseline. It's one of the most expensive products that I have bought, used, and wanted to rebuy over and over again and keep recommending, but it's like, dang, that price point is rough. So, look out for Paula's Choice sales. It's usually pretty good. I would definitely get it during the sale for sure."

"As far as ectoine standpoint, the Paula's Choice one is good. I would have ranked it very highly, but I still would outrank Paula's Choice on this one. It's better. I see more of a noticeable change with that product, and it's just a richer, nicer, more emollient texture, too."

"Ectoin is fantastic for dehydrated skin. This product is good for dehydrated skin. My skin is dehydrated. And I love this product. It's getting cold and that definitely means drier environment inside, cold, windy, harsh weather outside. My skin is feeling dehydrated for sure, but also dried out as well. And so this is the time of year where my combo skin, especially the T-zone, starts to go really dry. And the irritation from the dehydration can really settle in if it's not balanced out properly. I'm actually waking up with a lot less of that because I've been working this into my skincare routine. 7% ectoine, which I've been obsessed with ectoin for over two years now, and it's really had a moment this year."

"I'm getting the moisture that I need for the dryness that I'm starting to feel in my skin, but I'm getting that deep down hydration that is solving the dehydration that's really helping my skin barrier as well, all in one bottle. I absolutely love this."
