Great, comfy bed - so good I bought 2!
Size: 23 in, Size: 23 in
My dog loves this bed, I have one at home for him and one in my office at work (in pic). He sleeps so soundly on it. He’s about 7 lbs and it’s a great size for him, he likes to stretch out when he sleeps. It’s a simple, comfy bed good for dogs about 5-12 lbs. You may want to go one size bigger if your dog is 13-22 lbs.

The Kind of Cream That Makes Your Skin Look Smoother, More Refined, and Just… Better
Color: Collagen, Size: 1.69 Fl Oz (Pack of 1), Color: Collagen, Size: 1.69 Fl Oz (Pack of 1)
At 52, post-menopausal, with dry, increasingly sensitive skin, I’ve become very selective about creams that promise pore refinement, firming, or smoothing. Those claims can go wrong quickly. A lot of products aimed at “pores” are too drying for mature skin, and a lot of “firming” creams end up feeling heavy, silicone-heavy, or overly cosmetic. This cream surprised me because it manages to feel supportive and refining without pushing the skin too hard.
That balance is exactly why it works so well for me.
First, it’s important to set expectations correctly. This is not a miracle product, and it’s not going to literally shrink pores or dramatically transform the structure of your skin overnight. What it does do — and does very well — is improve the surface quality of the skin. My skin looks smoother, more hydrated, more even, and more refined when I use it consistently. And at this stage, that kind of steady improvement matters far more than dramatic claims.
The texture is one of its strongest points. It has a smooth, elegant cream texture that feels substantial enough to moisturize properly, but it never tips into heavy or greasy. It spreads easily, absorbs well, and leaves the skin looking soft and supported rather than coated. For dry, mature skin, that is not always easy to find. I want comfort, but I do not want a cream that just sits on top of my face and makes everything feel overloaded.
What I notice most with this cream is how it helps my skin look more polished and refined. The skin feels softer to the touch, looks smoother through areas where texture can become more obvious, and has that hydrated, slightly firmer look that makes the whole complexion seem healthier. The effect is subtle, but very real. It’s less about “wow” overnight change and more about waking up and noticing that your skin just looks better behaved.
I also appreciate that this does not feel like a pore product in the harsh, stripping sense. A lot of products marketed around pores are clearly made with oilier, younger skin in mind. This feels much more compatible with skin that is dry and mature. It gives you that smoother, more refined appearance without sacrificing comfort, and that makes it much more useful in a long-term routine.
Another strength is how well it layers. It sits beautifully over serums, doesn’t pill, and works well under sunscreen and makeup. That’s a major point for me, because if a cream disrupts the rest of the routine, it doesn’t matter how good it sounds on paper. This one integrates easily. In fact, I find that makeup sits more smoothly on top of it because the skin underneath looks more even and hydrated.
The packaging is also worth mentioning. I really like the pump bottle format here. It feels hygienic, easy to use, and more practical than repeatedly dipping into a jar. It also makes the product feel more treatment-focused, which suits the formula well.
The scent is minimal and clean, which I prefer. Nothing perfumey, nothing distracting, and nothing that makes the experience feel irritating or overly fragranced.
Value-wise, this sits in a good place for me because it performs like a treatment moisturizer rather than just a basic cream. You’re getting hydration, smoothing, and that more refined skin finish in one step. And because you don’t need a huge amount each time, it should last reasonably well.
For me, this is the kind of cream that earns its place by being consistently useful. It doesn’t overpromise. It doesn’t overwhelm the skin. It simply helps the skin look smoother, more balanced, and more refined over time — and for mature skin, that is often exactly what you want.

243 dalton cream
Color: Collagen, Size: 1.69 Fl Oz (Pack of 1), Color: Collagen, Size: 1.69 Fl Oz (Pack of 1)
LOVE this lightweight cream. I live in a very dry climate and need something I didn’t have to reapply. This last for 24 hrs easy, makes my skin soft and radiant! It’s 243 daltons which makes it easy to absorb in the skin. Have I reversed signs of aging, of course not but it makes my skin more liveable. Even, smooth and bright are the best possible outcomes I am happy to get.
Recommend use with the other collagen products which are soothing to the skin!
I love this BIODANCE product. Worth every penny!

Hydrated
Color: Collagen, Size: 1.69 Fl Oz (Pack of 1)
I’ve been using Bio Dance cream and it feels very moisturizing and soothing on my skin. The texture is smooth, lightweight, and absorbs nicely without feeling too greasy. My skin feels softer and more hydrated after using it, especially when my skin feels dry or tired. It also works well under makeup and gives a healthy glow. A great cream for keeping the skin calm and hydrated.

Absolutely LOVE this product and product line!!!
Color: Collagen, Size: 1.69 Fl Oz (Pack of 1)
Love it! I have noticed that buy using this entire system my skin looks plump - i.e. super hydrated!! I would agree that the product plumps (no weird tingling type of plumping). I have noticed that my pores do appear slightly smaller. This does leave your skin feeling slightly sticky, but it goes away once it has dried or soaked in. The sticky is not sticky it's more like your hair might stick to it a little bit. It does not last long and that factor also depends on how much product you are putting on. in the morning, I do a thinner layer of the cream. At night I put a thicker layer on. This product when used with the system makes my skin feel and look very soft, hydrated, and glowy. I have sensitive skin and I have no issues with irritation. In fact, I have acne prone skin, and my acne has fully cleared up since I began using this product line a month ago.
I LOVE and will continue to use! Highly recommend!
