There are a number of different types of collagen; the most prevalent two in the human body are types I and III. In fact, type I collagen is the most abundant protein in the human body - it is present in almost every type of tissue. Bone contains almost exclusively type I collagen. The collagen network in bone confers structural strength to bone tissue and prevents bone fragility. Deficient or defective collagen production, as can occur with aging, is a risk factor for fractures and other bone deformities. Type I collagen is also the major protein found in skin connective tissue where it is responsible for providing skin with its tensile strength and resiliency. Type III collagen is found at high levels in cardiovascular tissue and also in newly developing skin. It is essential for the proper development of the cardiovascular system and skin tissue. Types I and III collagen are often found together in the same tissues, as each form complements the structural integrity of the other. Vitamin C is required for the synthesis of collagen and participates at nearly every step of the process.

Cute but wide
Color: Tortoise Frame/Brown Lens
cute sunglasses that look nice on but are a little wide for my more narrow face. They do fit well enough for me to wear, it’s just they’d definitely fall off if I lean down in them. I think I’m going to keep them though. Construction wise, they are nice, very light which makes them more comfortable and the tortoise color is pretty. Overall nice sunglasses for the price.

Perfect shades

I love these sunglasses! I have a small face, and I find that these fit perfectly! They are stylish, fun and I don't have a problem of them sliding down my nose.

Worth Every Penny!

"I absolutely adore these sandals! They look elegant and minimal, making them perfect for dressing up or keeping it casual. Crucially for me, they are incredibly comfortable. The straps are soft and don't dig in at all, and I could walk in them all day. The quality seems top-notch. Highly recommended!"
