What Is Collagen?
Collagen is the most abundant protein in our body, found everywhere from joints and ligaments to the hair, skin and nails. It's made up of a series of amino acids, and because it's quite rigid by nature, it works well to hold things together like an in-built support system.
What Does Collagen Do?
When we're young, our collagen levels are high, hence a springy, bouncy complexion. As we age, our collagen production slows down, causing signs of ageing — loss of volume, brittle nails, thinning hair and slackened skin.
Do Collagen Supplements Work?
Yes, but they aren't a quick fix. Collagen supplements are designed to support a healthy diet and lifestyle overall. Good nutrition, sleep and daily sunscreen are your first line of defence, but emerging science suggests ingestible blends are an effective complementary option.
How Long Does It Take?
Around eight to 12 weeks. Like any skincare routine, you have to take your collagen supplements consistently over time to see results.
