Ingredient women should add to their coffee to 'reduce wrinkles' - it's 'great for your skin!'

Taking to TikTok, Robert Love (@robertwblove) advised people to stock up on broccoli, wild-caught salmon and collagen protein.

Collagen - a protein that helps form the connective tissues of the body, including the ligaments, muscles, tendons and skin - depletes with age. In fact, by the time women are 55, they have lost approximately 50 per cent of the collagen in their skin.

Explaining the importance of combatting this depletion, the neuroscientist said: "Research shows that women who take a collagen protein supplement have stronger bones, stronger muscles and fewer wrinkles on their face.

"So not only is collagen great for your skin, it's also good for your bone density and muscle strength as well."

"Something I like to add to smoothies but you can also add to coffee is collagen protein.

Collagen may also have excellent hair-boosting benefits. Indeed, one model revealed that her secret to great hair is collagen.

The experts at the skin care and cosmetic clinic, Victorian Dermal Group, confirmed the benefits of collagen for the skin.

They said: "Do collagen supplements reduce wrinkles? Does taking collagen prevent wrinkles and skin wrinkling? In a way, yes.

"For sensitive skin or skin that is starting to age and weaken, ingesting collagen peptides can improve hydration and skin elasticity.

"Taking collagen as you age is especially important, as many of us experience decreased collagen production over time.

"Collagen fibres have also been proven to reduce wrinkles and dryness in your skin, thereby slowing the ageing process and resulting in improved skin elasticity.

"For women, taking three to 10 grams of collagen derivatives per day for roughly 70 days greatly improved skin hydration."
