But what exactly is collagen, and is there scientific evidence to support these assertions?
Collagen is essentially a protein that plays a crucial role in maintaining the integrity of our body. Naturally synthesized within our bodies, it forms an integral part of our connective tissue, providing structure to bones, strengthening tendons and ligaments, shielding internal organs, and ensuring skin suppleness and hydration.
Our skin, composed of three layers – the epidermis, dermis, and hypodermis – houses collagen primarily within the dermis. Here, it forms a robust network of fibers, imparting strength and elasticity to the skin.
Unfortunately, collagen production diminishes as we age, with a significant decline occurring in the years following menopause. Factors such as excessive sun exposure, poor dietary choices, heavy alcohol consumption, and smoking further impede collagen synthesis. These factors can lead to increased free radicals, inducing oxidative stress that disrupts collagen production, eventually resulting in drier, less plump skin with the emergence of fine lines.
Can Collagen Supplements Enhance Skin Health?
The efficacy of collagen supplements remains a topic of debate. One theory suggests that collagen peptides, once digested, break down into individual amino acids, the fundamental building blocks of protein, thus providing the body with the necessary ingredients for collagen synthesis. Another hypothesis proposes that the presence of specific amino acids may stimulate collagen production by signaling a breakdown, prompting the body to compensate.
Among collagen supplements, two primary types are prevalent: bovine and marine collagen. Marine collagen, like that found in Skinful, predominantly consists of type 1 collagen, the most abundant type in the human body. Notably, marine collagen boasts a smaller molecular weight than bovine collagen, facilitating better absorption. Additionally, it contains elevated levels of glycine, an amino acid known to enhance skin elasticity and hydration.
Several studies corroborate the benefits of marine collagen supplementation for skin health. A meta-analysis conducted in 2023, involving over 1700 participants, concluded that marine collagen supplementation significantly enhances skin elasticity after 90 days of use. Moreover, it identified marine collagen as the optimal source for improving skin hydration.
A 2018 study further supports the positive impact of marine collagen on skin health. Within six weeks of supplementation, participants reported improved skin hydration, with continued usage over 12 weeks demonstrating enhancements in elasticity and reduction in wrinkles.
