Why do we need to protect our skin from environmental and UV damage.

  When it comes to extrinsic ageing, science shows that there is a significant reduction in collagen 1, 3 and 7 when we are exposed to these environmental factors. We need to protect the skin from this kind of damage as well as cellular damage. Cellular damage is hugely impacted by something called Free Radical Theory. This is where atoms steal electrons from healthy atoms causing more inflammation and more damage to the DNA and cell structures. That propagates more free radical damage and breaks down collagen fibres

What causes skin to age ?

Skin ageing is caused by a combination of different factors, both internal and external. Understanding the way that internal and external factors affect skin’s structure and function can help to inform skin care choices and prevent premature skin aging. Internal factorsYoung skin has a thick epidermis and a strong network of collagen fibres.Mature skin has a thinner epidermis and a weakened network of collagen fibres.

How does skin change over the years?

Skin is a living organ and undergoes significant changes during a person’s lifetime: from the delicate skin of a new-born baby, through the teenage years when some are acne-prone, to the wrinkles of later life. Each stage has its own demands and skin care should reflect these changing needs. Choosing appropriate products to cleanse, protect, nourish and repair skin at each of these stages will help to keep it healthy and ensure that your skin looks and feels its natural best, whatever your age. How is skin different at each age and stage?

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.

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.

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.
