Step inside a health food shop – or, really, any high-street supermarket or chemist – and you'll find rows and rows of pills promising everything from better joint mobility to shinier hair, stronger nails and clearer skin.

Welcome to the age of the skin supplement. The popularity of ingestible beauty and wellness boosters is rising, with the category growing an average of 13.8 per cent each year since 2015, and beauty-specific supplements growing faster than the wider category.

Today's beauty arena has created the perfect environment for inside-out supplements for skin to thrive: now, presenting as fresh-faced and radiant is the the ultimate health-signalling humblebrag. Where showcasing your pro-level make-up skills was the beauty goal of five years age, now it's far more satisfying to shine a spotlight on your natural and (seemingly) effortless glow.

Meanwhile, advances in the supplement space are allowing brands to bypass challenges such as potency, preservation and absorption, meaning the best skin-boosting pills can actually deliver on their promises – a far cry from the sponsorship-soaked supplement gummies of the influencer age.

It seems that now, almost any aesthetic concern can be tackled from the inside out, with as little effort as it takes to swallow a daily capsule. Of course, a well-rounded diet and balanced lifestyle are the foundations for everything from shiny hair to glowing skin, but a supplement can provide a targeted boost.

“Supplements work by providing the taker with an additional provision of nutrients that their body may require for certain functions,” explains registered nutritionist Clarissa Lenherr. “For those who may not be able to get all the nutrients they need from their diet, this can be a great way to avoid low levels or nutritional deficiencies.”

“When it comes to nutrition and skin, I believe that your diet and lifestyle choices should always be the first things you look at. However, I fully appreciate that there are things that are out of people's control or difficult to manage, such as stress, or that diets can be limited in certain nutrients (for example, being vegan or vegetarian). In these instances, supplements for skin health can be helpful,” she adds.

“When we eat nutrients or take supplements, the body distributes them to the priority organs – such as the heart and liver – before anywhere else in the body,” says Lorraine Perretta, head of nutrition at Advanced Nutrition Programme. “If you do not have a nutritious diet, the nutrients you eat will all be used up by these essential functions and there will be less to support skin health. For skin super-health you need to ensure you have plentiful amounts of nutrients in the body – and supplements are a good way to top up what may be lacking in your diet, ensuring that key nutrients can work in the skin.”

The key to supplement success? According to Perretta, it’s all in the synergy. “All the vitamins and minerals in your body work together, and if you do not have one of the vitamins necessary to carry out a specific process, the body struggles to complete the activity. Therefore, it is important to ensure that the body has a good variety of all the nutrients needed, and we can support optimum levels in the body with supplements,” she says.

Supplements for skin: where to start?

According to Perretta, multivitamins and probiotics are a good starting point for anyone new to supplements. “On top of that, you would include additional supplements to act as boosters for concerns you specifically want to target. For example, perhaps you would use a retinol serum if you were concerned with the signs of ageing. With supplementation you could add a vitamin A skin supplement to your capsule regime to tackle your concerns from the inside out.”

Which skin supplements show promise?

Collagen supplements have proved especially prevalent in recent years and, according to Lenherr, there may be tangible benefits to taking them. “Collagen is one of the supplements I do consider with clients who consult with me on their skin health,” she says. “Collagen is the most abundant protein in the body, one of the key components of skin, and plays a role in structure, elasticity and hydration. One randomised, double-blind placebo study showed that after eight weeks of taking collagen, participants experienced increased skin moisture, and after 12 weeks saw decreased collagen disintegration.”

However, there are limitations to the powers of taking collagen internally. “When creating supplements, there are a number of things that need to be considered: bioavailability of the nutrient, delivery method, absorption and utilisation of the individual," adds Lenherr. Of course, every body is different, and our ability to absorb, utilise and benefit from a supplement will vary from person to person.

Absorption issues are especially common with collagen, meaning a sub-standard supplement likely won't deliver any noticeable benefits. The solution is to choose a product containing a hydrolysed form. “Hydrolysed collagen peptides have shorter chains of amino acids than collagen obtained from food sources,” explains Lenherr. “This makes them easier to digest and absorb into the bloodstream.” Scan the back of your bottle carefully before investing: a company using hydrolysed collagen will state it loud and clear.

Another promising beauty supplement ingredient is vitamin C, which “contributes to collagen formation, supporting healthy skin strength. Plus, its antioxidant status can help protect your skin from oxidative stress,” says Lenherr.

Vitamin C has dozens of roles in the body – immunity, energy, mood, and many more – but the skin receives it last,” adds Perretta. “This means that if you do not have enough supplies of vitamin C in the body, it cannot fulfil its important roles within the skin: maintaining collagen, brightening and acting as an antioxidant.”

Finally, vitamin E may deliver noticeable improvements to the skin, especially when it comes to fighting external aggressors. “Like vitamin C, vitamin E is an antioxidant, which can help to reduce free radical damage (from sun exposure and pollution) that impacts DNA, skin, cells and connective tissue. Therefore, vitamin E can play a protective role with skin. However, be cautious not to take too much, as it can reduce blood clotting.”

Probiotics for skin

Probiotics are booming, and their benefits don’t stop at the gut – but how exactly can they influence the appearance of our skin on the outside?

“When we have dysbiosis in the gut (a bacterial imbalance), we are more likely to develop inflammatory conditions, and an increase in inflammation in the body has been linked to higher incidence of skin conditions,” explains Lenherr. “Additionally, bacterial imbalance in the gut can impact other bodily collections of bacteria, including the skin microbiome. For example, overgrowth of bacteria in the small intestine, a condition referred to as SIBO, has been linked to rosacea and acne.”

Perretta believes probiotics to be an incredibly exciting and emerging ingredient in the world of skincare supplements.” A lot of new research is driving interest in the area, and our understanding of how probiotics influence the skin is evolving all the time. Previously, it was thought that probiotics only impact the gut, but we now know that they can affect much more – including the skin.”

Gallinee Clear & Microbiome supplement

The gut microbiome relates to the varying microorganisms, including bacteria, that reside in the digestive tract. “Having a diverse, healthy gut microbiome not only encourages better absorption of nutrients but is linked to overall skin health. Specific strains within the gut can target different mechanisms in the skin, and bacteria supplements can use this understanding to specifically target skin concerns,” says Perretta. For example, Advanced Nutrition Programme’s Skin Youth Biome contains four bacterial strains to target the signs of ageing, while Gallinee (a market leader in probiotics) Clear & Microbiome uses specific strains of bacteria to tackle the root cause of acne.

However, not all probiotic supplements are created equal. “Working with living bacteria is always a challenge – they need to be kept alive until they reach the area of the gut where they are needed,” she adds. To achieve this, the bacteria must either be acid-resistant (as some strains are) or coated in a protective capsule. It’s also tricky to find effective probiotic supplements that are vegan-friendly, as most bacteria need to be fed on dairy products.
