Collagen is the main structural protein in human connective tissues, most notably our skin. The vast majority of the collagen in our skin is found in the dermis the second layer of skin that sits beneath the epidermis), where it's also produced. Skin cells in the dermis (fibroblasts) synthesize the collagen that holds the rest of the dermis together, giving our skin its underlying structure.
As for the structure of collagen itself, it’s kind of like a braid or rope: Individual amino acids link up to form long chains, which bundle together to form thicker strands. Those strands then twist and coil around each other to form triple helices. Finally, those helices connect end to end and stack on top of each other to form clusters called fibrils. In other words, collagen is a pretty complex and massive molecule.
That’s why creams formulated with pure collagen simply can’t live up to their lofty claims— those huge braided molecules are just too big to penetrate your epidermis, and definitely too big to get down into the dermis where the real magic happens. So even though collagen creams feel nice and may help moisturize the skin, that’s about it in terms of benefits.
Fine lines are the delicate lines that form on delicate skin (like the face), as collagen and elastin decrease. These shallow lines can appear when the skin is dehydrated or as a result of sun damage. They can also be among the first signs of skin aging and, if they deepen over time, can be the precursor to wrinkles. Usually found around the eyes, lips, and forehead, fine lines can appear anywhere that expressive facial movement are regularly repeated—such as smiling, squinting and furrowing the brows.
To prevent fine lines and wrinkles, it’s best to moisturize daily and wear sunscreen. Additionally, antioxidants protect the skin from free radicals that damage cells and speed up aging. Ingredients and nutrients like rosehip oil, jojoba oil, red tea extract, retinol/vitamin A, coenzyme Q10, glycolic acid and salicylic acid are all beneficial for preventing and reducing fine lines and wrinkles. Peptides and ingredients that boost the production of collagen like vitamin C are good for boosting the plumpness of skin, reducing the appearance of fine lines and wrinkles.
collagen may be effective for fine lines, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you. Take this skin quiz to find the best ingredients for your skin and build your skincare routine.
