Love the scent! Paraben free and really hydrating
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1), Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
I've never used any Karl&Hans product before, but I'm really impressed with what they've done here. Contrary to the very European name, this lotion is made in Korea. The Mellow Coconut fragrance isn't subtle, but it's relaxing. It's blatantly coconut right off the bat, but when it settles in, there's a lingering fruity vanilla scent. It'll stay wafting around you for a good amount of time after application.
The lotion is pretty rich and thick in consistency. It's not quite a cream, but it's thick enough that it doesn't run much, or at all, when you plop some on a vertical surface. That might just be because it's cold where I am, though, so it might be more runny in hotter climates. The thickness betrays how easily it rubs in. It's super quick to absorb and hydrates well without feeling heavy. My skin feels moisturized but not sticky or greasy.
PDRN seems to be the hot buzz ingredients of the times right now. I'm not fully educated in the science behind it, but this lotion is really turning me into a believer of whatever skincare magic it's supposed to work. According to Skin Safe, it's also free of parabens, nickel, lanolin, and a bunch of other top common allergy causing preservatives.
At $23 for 13.2 fl oz/390 ml, this is definitely steeper in price than your average body lotion, but it works some serious magic in the moisturizing department. It's been a good while since my skin felt so satisfyingly supple. I'd prefer if the scent weren't quite as strong, I can't deny it smells good.

Side by side comparison ......
Scent: Fresh Mint, Size: 13.2 Fl Oz (Pack of 1)
Like everyone else shopping around for lotion, I want one that, most importantly, works. I'm so very tired of lotions that feel like I'm applying colored water to hands so my go to lotion has become Gold Bond as it's a genuinely thick, somewhat long lasting lotion with minimal scent at a decent (ish) price point. I am however, always looking to find something even better so I thought I'd give this stuff a try. This is just an estimation, but I feel it is about 20% less viscous than the Gold Bond Healing lotion however, in a side by side test where I applied the back of one hand with the GB and the back of the other with this K&H brand, after one hour the K&H feels every bit as supple but just a tad more velvety if you will. Although I prefer a non scented lotion, after an hour, the K&H scent has indeed lighted up a bit but smells better than the GB. The GB seems to almost have an underlying petroleum type odor - not offensive really but just that the K&H smells better to me is all. The Gold Bond does get the favoring nod in the price dept though as it's very close to 50% less expensive than this Karl & Hans. If all things were equal (and that includes the price), I'd pick the K&H over the GB however with price point always being of concern for me personally, I don't think the attributes of the K&H beat out the overall value of the GB.

Great! Unscented
Flavor Name: Unscented, Size: 1 count (Pack of 5)
Good natural ingredients, you can tell by the scent and texture and the ingredients list is spot on, no lies. This is perfect for sensitive skin. It has a pleasant olive oil scent and I have never gotten a rancid smell from it. The natural preservatives keep it nice. I have re-ordered over and over. Good product

Love this All Natural, Made in America, Refreshing Mint Lip Balm!
Flavor Name: Fresh Mint, Size: 1 count (Pack of 5)
This is my fourth order of Mint Tallow Honey Lip Balm from Terra Lotus. My entire family of 6 (including 2 picky teens) loves this lip balm and reaches for it over the popular yellow brand of lip balm we still have laying around (even though I don't buy it anymore).
I love that Terra Lotus is an American company and their grassfed tallow and honey products are Made In America. I also love that I can pronounce every one of their ingredients, each of which could be edible. Please continue making this lip balm forever...especially in Mint!
