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.
Pigmentation is simply skin’s coloration, determined by the amount of melanin produced by the skin cells. This umbrella term can include a wide variety of skin pigmentation disorders that can affect small or large areas of the skin. It includes genetic conditions, as well as environmental ones, such as sunspots or liver spots. Hyperpigmentation, for example, refers to a darkening of the skin, such as with age spots and sunspots.
To prevent discoloration from damaging UV, 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 acai oil, alpha-lipoic acid, jojoba oil, green tea extract, retinol/vitamin A, coenzyme Q10, caffeine, alpha-hydroxy acid and salicylic acid are all beneficial for preventing and reducing the appearance of hyperpigmentation. Vitamin C is also a good brightening agent for hyperpigmentation. Hydrolyzed collagen also enhances the appearance of dull or damaged skin by reducing flaking and restoring the overall vitality of the skin.
collagen may be effective for pigmentation, 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.
