Seborrhoea Dermatitis
What is seborrheic dermatitis?This is a common skin condition that causes a scaly rash on oily areas of the body like the scalp and face. The rash can appear on the skin in many different ways, and sometimes looks like another dry skin condition. Manage dietary sugar intake to reduce internal triggers. Sebborhea dermatitis can cause irritation on skin as the scales from the scalp land in the facial skin .

What causes skin ageing?
Skin ageing is caused by two main processes; intrinsic and extrinsic. They both contribute to the visible signs you may see on your skin, such as fine lines, wrinkles, loss of firmness, and discolouration.

Hyperpigmentation.
The word hyperpigmentation is the umbrella term that loops together many different types and causes of excess pigmentation issues, from hormonal melasma, sun spots, age spots to PIP (Post Inflammatory Pigmentation) caused by scaring such as acne scaring or injury.

Trans epidermal Water Loss – What is it and How to Stop It
If you are struggling with dehydrated or dry skin, one of the causes may be trans epidermal water loss (TEWL). You're losing water and moisture from your skin. TEWL can lead to a variety of dry skin conditions — including severe dehydration — but there are ways that you can keep your skin hydrated or prevent dryness from occurring in the first place. What Is Trans epidermal Water Loss? To understand TEWL, let's revisit the layers of our skin. Our skin is made up of three primary layers, the outermost being the epidermis (aka what you look at in the mirror). The dermis is the middle layer, and the hypodermis is the innermost layer. TEWL occurs when water passes from the dermis through the epidermis and evaporates through the skin barrier.

The Science behind daylight/ darkness and restful sleep.
What can you do to optimise light for better health? The simple rule of thumb is to expose yourself to as much daylight as possible during the day (without looking directly at the sun!), as little light as possible in the evening, and absolutely no light when you sleep (i.e. sleep in complete darkness).

Antioxidants Explained.
Antioxidants - When we’re exposed to UV, pollution or other stressors such as smoke and chemicals, free radicals form in the skin. At a cellular level, these free radicals can kick off a chain reaction that causes a huge path of destruction and often, ultimately, the death of the cell.

Lipids such as Cholesterol, Essential fatty acids and Ceramides and their role in ageing skin.
Essential fatty acids, Ceramides and Cholesterol are all naturally occurring lipids in the correct ratio in healthy skin. Lipids are the good fats in your skin that make it look healthy and young; as you age, your skin loses them, causing dullness, dryness, and wrinkles. These healthy fats play a critical role in maintaining a healthy functioning skin barrier. The skin barrier is Crucial for this skin barrier function is the lipid matrix in the outermost layer of the skin, the stratum corneum.

Acne-Rosacea
Acne Rosacea -Rosacea is a complex skin condition , with inflammatory triggers, in which environmental factors can interfere negatively or positively in its evolution. Our skin barrier can be disrupted due to many possible reasons. When it’s damaged the tight junctions between the skin cells are lost. This allows external irritants to get in our skin a lot easier and lead to more water leaving our skin, leading to a dry tight feeling. Damaged skin barrier is characterised by an easily irritated, dehydrated and flaky skin, red skin. Improving the skin barrier function can significantly reduce symptoms, plus reduce inflammation. Up to 30% of rosacea sufferers have a family history of the condition leading researchers to believe it involves as yet unidentified genes, and for some, this is an inherited condition.

Free radicals & Antioxidants.
What are free radicals?Natural chemical reactions in our cells produce unwanted by-products called reactive oxygen species (ROS) – better known as free radicals. These furiously ping about inside cells causing havoc, particularly a type of damage called oxidation. Seen an apple go brown? Smelt oil or nuts that have gone off? That’s oxidation. Unchecked, a disastrous chain reaction would occur in which cell’s most precious elements – their fat rich membranes, their proteins and DNA - would degrade and suffer irreparable harm.There’s also a whole other source of free radicals - the environment. The skin is bombarded by sunlight (UV, infrared, visible light), weather and pollution which trigger the production of free radicals.

What can be done to slow the ageing process?
We start losing collagen from the age of 20, starting the creation of lines and wrinkles. Healthy skin reflects overall health, and poor nutrition can contribute to factors that accelerate skin ageing.Environmental factors such as ultraviolet radiation, pollution, nutrition and stress, play a key role in the way we age. Research also suggests that a diet rich in sugar contributes to the loss of collagen in the tissues as the result of a process known as glycation, which can destroy collagen. Smoking kills vitamin C and in turn damages collagen.

Discolouration and Dark Circles Under the Eyes
Dark circles, also known as periorbital hyperpigmentation, are a commonly encountered condition best described as the darkening of skin pigmentation around the eyes. Whilst dark circles are not usually caused by an underlying medical condition, many people think they make them look tired, sad or older than they are, and therefore can affect their emotional well-being .

Antioxidants help to protect against Free Radical damage.
Free radicals are unstable molecules that can cause damage to our cells. What makes them unstable is that they are missing electrons from their outer shell. This causes them to search for other atoms or molecules that have these electrons, in order for them to feel whole again and become stable. Due to their reactive nature, free radicals can wreak havoc on your skin and other cells in their quest to find an electron and feel whole again. In order to stabilise themselves, free radicals try to bond to other atoms or molecules.

Is technology ageing your skin ?
Technology can damage your skin.Blue light, also known as HEV (High Energy Visible Light) is naturally emitted from the sun, it is also produced from our digital devices, phones, computers, etc. Like UVA and UVB light, blue light can contribute to premature skin ageing, and, studies show that adults are spending a significant amount of time using digital devices. Blue light is not only affecting our skin, but it’s also having a negative impact on our sleep. By disrupting our natural circadian rhythm; Blue light in the form of daylight wakes us in the morning but being exposed to a significant amount of blue light before bed can make it harder to get to sleep as the blue light at night keeps you more alert.

Your skin’s greatest enemy is no longer just the sun.
Since pollution is all around us, the best thing we can do is to make sure we give our skin the best protection available. Sunscreen is no longer enough. With these new findings, it is ever more important to replenish your skin’s antioxidant levels either through diet, topical products or both.

Skin Ageing - the causes .How the Environment Ages Your Skin?
Aging is inevitable. As we get older, our bodies’ natural ageing processes kick in, causing the skin to sag and fine lines and wrinkles to set in. It’s a fact of life. But, did you know that time only accounts for 10% of skin changes? The remaining 90% is caused by external influences that accelerate the ageing process. Read on to learn about three sources of environmental ageing and how you can protect your skin from damage.
