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.
Age spots on your skin is known as hyperpigmentation, dark spots, or liver spots. There are several reasons you might experience hyperpigmentation, but those we are referring to here are those that are caused by acne scarring or sun exposure. Age spots are most common on the face, the shoulders, and the back. There are some age spots that might appear as a side effect of certain medications. Age spots are typically harmless, but we always recommend conferring with your dermatologist if you’re experiencing a larger-than-usual area of age spots, or if they are changing in color, thickness, or appearance in any way.
To prevent age spots, 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 vitamin C, acai oil, jojoba oil, alpha-lipoic acid, green tea extract, retinol/vitamin A, coenzyme Q10, caffeine, alpha-hydroxy acid and salicylic acid are all beneficial for preventing and reducing age spots. Hydrolyzed is also good for restoring the overall vitality of the skin.
collagen may be effective for age spots, 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.
