How DNA Can Reveal How You’ll Age


DNA tests have unravelled some of the biggest mysteries of our time. From unsolved crimes to determining paternity, these simple swabs can offer pretty accurate insights into some truly intimate issues. And today, an Aussie genomics company is adding signs of ageing to the list.

Founded by dermal expert Stefan Mazy, SkinDNA is leading the industry in research and scientific advancement in predictive skin ageing and clinical product offering. By taking a simple DNA swab and answering a lifestyle questionnaire, it offers participants the opportunity to receive a personalised skin report that highlights their risk levels against five categories of ageing. Alongside it, comes recommendations of specific topical ingredients, supplements, and professional treatments unique to your skin.

We chatted to Stefan who helped breakdown the five signs of ageing. With our top suggestions to keep your skin looking fresh – whatever your DOB!

DNA says: Keep calm and collagen

A major component of your muscular and bone health, collagen also plays a starring role in strengthening skin – benefiting elasticity and hydration. In fact, it is the most abundant protein in your body, making up 75 percent of the skin’s dry weight.

“When you are younger, your body makes more collagen than it loses. However, after about the age of 40, collagen loss can accelerate, leading to a decline in the health and appearance of the skin” says Stefan. Of course, the rate you lose it depends on your DNA, but it’s never too early to instil preventative measures.

Although a small 2009 study found that topical collagen cream may help reduce fine lines when applied twice a day for three months, and some vegan collagens claim to penetrate deeper into the skin, generally speaking, the most effective way to improve collagen levels is through oral consumption – which has been shown to increase collagen growth and improve wrinkles and skin elasticity.

Alternatively, some experts recommend using red light therapy (professional or at home) or high-grade cosmeceutical ingredients that are scientifically proven to stimulate your body to produce its own collagen.

Specifically, evidence suggests that skincare actives, such as vitamin C, hyaluronic acid and niacinamide (vitamin B3), are most effective. With each of these ingredients delivering their own unique skin-boosting benefits, including them in your skincare routine as a means of promoting collagen production ultimately delivers an anti-ageing double punch.
