DISCOVER MORE about the physiology of your skin, the challenges it faces as we age and how our probiotic ingredients can help maintain its appearance. As one of the first brands to innovate in probiotic skincare, our science remains unique.


Designed to reduce cellular damage and promote the production of collagen and hyaluronic acid for plump, dewy skin that glows, PROTIDA™ is at the leading edge in probiotic innovation. Three unique probiotic complexes combine to boost the skin’s natural immunity, managing inflammation and enhancing repair for powerful results from within.

Aurelia London’s PROTIDA™ technology continuously protects, restores and balances the skin by calming the natural inflammatory response which can be overstimulated by factors such as pollution, sunlight and stress. PROTIDA™ in turn reduces the damage that inflammation can cause to collagen, elastin and healthy cells, and helps to maintain the skin’s natural equilibrium.


Our advanced PROTIDA™ technology works to calm the natural immune triggers in your skin, which can be overstimulated by pollution and stress.

We pride ourselves on being probiotic skincare pioneers who lead the way in harnessing our science which remains unique to this day. We want our products to make a real difference by delivering glowing, balanced skin every day.

We don’t use live bacteria or work on the skin’s surface microbiome – we believe there is a much better, more advanced way. We use a non-live probiotic from bifido bacteria in the form of a glycoprotein (a molecule which helps cell-to-cell communication) which we then combine with a milk peptide to protect and restore your skin from within.

We are different to all other probiotic skincare brands and have made a beautiful two-minute animation to explain how, please take a look above.

Having continuously pushed the boundaries of science and nature, we’ve won over 100 industry and consumer awards since 2013 for our brand and beautiful products.



How can I look after my skin’s microbiome / natural acid mantel

The microbiome, or the acid mantel of the skin, is a critical part of the jigsaw of healthy-looking balanced skin. It needs to be looked after with the utmost of care!

The biggest impact to the health of the natural skin barrier is actually caused by a number of factors but importantly how we choose to treat our skin has a huge impact. Many of us often use ingredients that are too harsh which strip the natural oils. This exposes the skin to irritants which leads to imbalance, redness and dryness as moisture escapes from the skin layers. Dermatologists call this TEWL (Transepidermal Water Loss).

The skin’s natural acid mantel or microbiome is delicate and needs to be looked after in order to help protect it. The best way to do this is by treating your skin gently and avoiding harsh preservatives, especially MI, and foaming agents (SLS), strong acids peels and pads as well as too much exfoliation. Stress, hormones and lack of sleep can also impact the skin barrier negatively so looking after yourself also helps to promote healthy looking skin. External factors add to this including daily pollution, grime, extreme weather and harsh sunlight.

At Aurelia London we believe that avoiding certain ingredients on your skin improves the acid mantel and that using our probiotic products in combination helps restore, balance and protect the skin from within. By effectively working on immune triggers within your skin you will be protecting it from daily pollutants and the impact of day-to-day challenges on the skin.

We use a Probiotic Milk Peptide to boost elasticity, collagen and natural hyaluronic acid levels

Aurelia London’s probiotic milk peptide works with our other probiotic ingredients to help stimulate cells (fibroblasts) that produce collagen (responsible for skin elasticity), hyaluronic acid (responsible for hydration) and fibronectin (responsible for skin support). These components give skin its youthful, supple and toned appearance and their deterioration leads to loss of skin tone, skin sagging and wrinkles.

The probiotic milk peptide delivers an active network of natural signaling molecules, including Transforming Growth Factor β (TGF- β), to stimulate fibroblast activity and restore the composition of the extracellular matrix resulting in firmer skin. Our scientific studies prove an increase in fibronectin synthesis of 220%, collagen synthesis of 140% and a huge 1,900% increase in natural hyaluronic acid levels. In addition, the Probiotic Milk Peptide has been shown to improve skin smoothness, reduce wrinkle depth and enhance the overall structure of the skin.

Aurelia’s eye treatment contains a powerful Eye Complex to dramatically reduce wrinkles

Aurelia London’s eye complex works on protein complexes within our skin cells (proteasomes) that are key for breaking down unwanted and degraded proteins, for example oxidised proteins that may be present in stressed or aged skin (caused by free radicals).

Although proteasome activity in our skin declines with age, Aurelia’s eye complex can recharge this activity and boost the natural protein recycling process in our skin cells. Our scientific testing showed that skin cells treated with Aurelia’s eye complex have double proteasome activity, compared with untreated cells after just 24 hours.

Our eye complex also boasts a 17-30% visual improvement in the appearance of fine lines.

Aurelia London's Pigmentation Complex used in our hand cream reduces pigmentation by 61%

The rate and stage at which we age depends on a number of factors including genetics, lifestyle, exposure to UV light and exposure to environmental stressors and internal factors such as stress and hormones. However, first signs of ageing usually occur in our mid to late 20s or early 30s, with fine lines appearing, pigmentation, a change in skin texture and loss of skin radiance resulting in dullness. Aurelia London’s high performance and core range has been specifically designed to target these early skin changes and continues to help manage the levels of inflammation within the skin as we age.


What happens to my skin as I get older ?

We all age in different ways depending on a number of factors including genetics, lifestyle, exposure to UV light, pollution and other internal factors such as stress and hormones. For many the first signs of ageing occur in our mid to late 20s or early 30s, with fine lines appearing, pigmentation, a change in skin texture and loss of skin radiance resulting in dullness. It’s not all bad news, by taking good care of your skin at any age huge improvements can be seen!

Skin in your 20s

In your twenties skin may still be going through lots of changes. With slightly higher oil production you may still experience breakouts although your overall complexion will be smooth and naturally radiant. Skin tends to settle down throughout your late twenties and establishing a gentle but effective routine here will help skin look fantastic in later life. Avoid treating the skin too harshly at this age, look out for ingredients that can cause irritation and avoid harsh exfoliants and acid pads which strip the natural skin barrier. Learn more about ingredients to avoid here.

Skin in your 30s

Skin in your thirties is when free radicals are on the loose, expression lines start to make themselves visible and sun worshippers may start to see some light sun-spots so make sure you use a minimum of SPF 30 on your face. Some women suffer adult acne at this age, just when they think things are improving. You might notice skin is not as radiant, as cell turnover decreases and collagen production slows down, causing less plumpness and the beginning of fine lines and early wrinkles. Studies show we are at our most beautiful throughout our thirties so make the most of it.

Skin in your 40s

Skin has all the potential to look lovely in your forties. You may still have the to-do list from your thirties but perhaps a bit more time to spend on yourself. At this stage you’re looking to keep a youthful glow about your skin, staying hydrated and increasing collagen production. You may have deeper expression lines, a lack of radiance and drier or more dehydrated skin as your natural sebum production decreases. All easily solvable with the right skincare to boost radiance, hydration and glow.

Skin in your 50s

Skin in your fifties can look fabulous but may start to change again so it’s really important to take extra care. Skin may continue to get drier and, if you’re going through the menopause, hot flushes can affect your skin too. Those with oilier skin will hugely benefit here and will show fewer signs of ageing. Enjoy the confidence you should feel in your fifties and embrace your beautiful skin!

Older & Wiser

In your sixties and beyond, collagen and elastin can decline further and the structure of the skin can become looser around the face and neck. Serums and treatments will boost your routine perfectly and overnight oils will become your saviour! As before, embrace your natural beauty and keep looking after your skin to maintain radiance.

Why does my skin sometimes look dull?

As we become older one of the main indications of ageing is when our skin starts to lose its natural glow and begins to look dull and tired. When young, our body’s renewal processes behave optimally and our skin cells turn over on average every 28 days. As we age the body’s natural ability for cell renewal deteriorates. Although the rest of our body may feel energised, the blood flow to our skin and the body’s natural replenishment process slows down and the skin’s natural enzymes that help remove and replace dead cells become inefficient. This can lead to dead skin cells piling up, which absorb light and cause our skin to appear dull and fatigued. Dullness is a major ageing skincare concern and one we focus on greatly improving at Aurelia Probiotic Skincare. For younger skins that suffer from dullness it is often caused by a build-up of unwanted ingredients have been on the skin. Silicones and mineral oils are commonly used and should be avoided. Silicones are often used to achieve a superficial silky feeling when applied to the skin but they do this by creating a plastic-like film. This alters the skin’s ability to process toxins and can mean irritants are trapped on the skin’s surface and pores are more easily blocked. The skin does not function and ‘breathe’ in the right way.

How do wrinkles form?

Smooth, plump skin relies on proteins called collagen and elastin. When these two proteins are compromised, wrinkles become visible. Collagen, together with elastin, is responsible for skin strength and elasticity and these proteins give skin its youthful, supple and toned appearance. Collagen strands within the Extracellular Matrix (ECM) help to hold the skin’s structure together and form the framework of tissues. As we age, and degradation occurs, these collagen strands slacken and can break, which causes the skin to sag and wrinkles to form.

Why do I have pigmentation?

With age, our skin becomes more prone to the development of pigment spots, a hallmark of photo-exposed skin.

Normally appearing on our face neck and hands, these clusters of excess pigment (melanin) are typically the combined result of prolonged sun exposure and high levels of stress in our skin cells.

This is because prolonged UV exposure and intense stress in our skin cells can trigger biological pathways that lead to overproduction of melanin in clusters of cells. This excess melanin is transported from melanin producing skin cells to cells in upper layers of the skin, where the dark brown spots form.

What do antioxidants do?

Thousands of natural antioxidants are found in fruit, vegetables and plants and include vitamins A, C, and E. Aurelia London is abundant in natural antioxidants from the precious BioOrganic botanicals used throughout the range that are ethically sourced from around the world. The high antioxidant content combats free radicals which are the cause oxidative stress, damage to the skin structure and, at excessive levels, induce an inflammatory response. They terminate chain reactions by removing free radical intermediates and inhibit other oxidation reactions. They do this by being oxidised themselves, working to reduce free radicals and prevent skin ageing. Aurelia London has been all over the world and searched for the very best botanicals which are rich in antioxidants to add to our scientifically developed formulations. Antioxidants are fantastic when dealing with the first signs of skin ageing and paired with our probiotic ingredients your skin will be balanced from within.

What role do free radicals play in causing our skin to age?

The damage free radicals cause to the skin is directly linked to a speeding up of the ageing process. When the skin is damaged immune triggers release collagen and elastin-digesting enzymes which unbalance the skin’s equilibrium. Collagen and elastin are important proteins which are responsible for skin strength and elasticity. They give skin its youthful supple and toned appearance and their degradation (caused by these harmful enzymes) leads to loss of skin tone, skin sagging and wrinkles. Make sure your products contain antioxidants to help fight free radical damage.
