Leucine is an amino acid that has anti-aging properties. It is used in anti-aging skin care products and is thought to help regenerate aging skin and reduce fine lines and sagging skin. It is said to create firmer, more supple skin and increase elasticity by repairing aging skin tissue. 

Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl glucosamine,acetyl tyrosinamide, alanine, arginine hcl, arginine pca, histidine, isoleucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.

This cult hydrating serum is formulated to boost hydration, smooth texture and plump the skin. The multi-weight hyaluronic acid and Natural Moisturising Factors (NMF) provide deep hydration and support the skin barrier, while superfood antioxidants help protect the skin and improved overall radiance.

Amino acids are the small building blocks that make up peptides, and proteins. Each amino acid has a unique structure, and as such plays a specific role within the body. There are around 20 different types considered to be most important for human health. In the outer layer of the skin, the stratum corneum, they are present in the ‘natural moisturising factors’, our skin’s own moisturising mechanism, and they help to support water transport between skin cells to keep our surface smooth and hydrated.

alanine

Allantoin occurs naturally in the body, but can also be derived from the root of the Comfrey plant or Chamomile, or produced synthetically. It is used in skincare for its ability to promote wound healing and healthy tissue growth, by stimulating the fibroblasts in the dermis to produce collagen and elastin fibres, essential tissues for skin regeneration and healing. Allantoin has also been shown to have soothing and anti-irritant properties, which is thought to be down to its ability to form complexes with irritating agents, thus preventing them from activating inflammatory mechanisms within the skin.

Arginine is an amino acid which occurs naturally within the human body. It is a popular ingredient in skincare for a number of reasons; it offers antioxidant protection, it hydrates the skin by stimulating the body's own production of humectants like urea and it can also repair visible skin damage.

Glycerin is a humectant present in all natural lipids. It works to attract water molecules towards it, plumping & hydrating the applied area, resulting in smooth, soft, hydrated skin. It is one of the most widely used humectants in skincare, due to it’s high performance and broad availability (making it very cost-effective). Recent research has shown that it’s ability to penetrate the layers of the skin is superior to that of low molecular weight hyaluronic acid, making it a brilliant choice for overall skin hydration, and suitable for all skin types.

glycerin

This ingredient is used in skincare for it’s hydrating abilities. It works by stimulating the production of Aquaporin 3, a natural substance found in the epidermis to regulate the movement of water between cells. An increased level of Aquaporin 3 in the skin results in improved hydration throughout the surface, and deeper layers, of the skin.

Hyaluronic acid is a polysaccharide which occurs naturally in the body. Hyaluronic acid works as an extremely powerful humectant, able to attract 1000x its own weight in water, to immediately plump and hydrate the area it is applied to. The body’s own production of hyaluronic acid slows with age, so supplementing this ingredient in topical formulations helps to support the skin’s natural moisture-binding, anti-ageing mechanisms.

Acetyl Glucosamine is an amino acid sugar

isoleucine

Lactic acid is an alpha hydroxy acid (AHA), which occurs naturally in the body, as well as being found in dairy products, but is typically derived synthetically for cosmetics today.

AHAs work by dissolving the keratin binding the outermost layer of skin cells, speeding up the skin’s natural exfoliation process. This leads to smoother, brighter, clearer skin, whilst reducing skin discolouration & fine lines/wrinkles with continued use.  

lactic acid

Lysine is used in skincare to treat hyperpigmentation & post-inflammatory acne scarring.

phenylalanine

prebiotics

Prebiotics in simple terms, can be classed as a food source that encourages the growth of good bacteria on the skin. The microbiome (the ecosystem of bacteria on the skin) is a relatively new discovery and we are learning that this is linked to many different aspects of our health, mood and appearance. A diverse breadth in the strains of bacteria living on the skin results in a healthy microbiome, and some early research has linked certain imbalances in this microbiome to skin conditions such as acne, ezcema and psoriasis.

proline

serine

Sodium PCA is the sodium salt of pyrrolidone carboxylic acid (PCA), which is found naturally in the body, and in the skin’s natural moisturising factor (NMF). PCA acts as a humectant, meaning it draws water to it, plumping and hydrating the area. The skin’s NMF ensures adequate hydration of the stratum corneum, which also works to support the overall barrier function of the skin, regulating trans-epidermal water loss (TEWL). Including Sodium PCA in skincare supports this natural mechanism of the skin.

sodium pca

Natural moisturising factor (NMF) is a substance produced by the body, made up of minerals, lactate, urea, amino acids & humectants, which coats the surface skin cells to keep them moisturised. NMF increases the skin’s ability to retain moisture, which results in more hydrated, plump, smoother skin.

soybean extract

Soybean extract is used in skincare for its powerful antioxidant potential, meaning it is able to protect the skin from free radical damage. Research has also shown this extract to be able to visibly even out skin tone, and reduce the visible signs of ageing.

taurine

threonine

Urea is humectant ingredient found in the skin’s natural moisturising factor (NMF), making up around 7-8% of the total composition. Its humectant properties mean it can bind to water molecules in the atmosphere, drawing them to it, and in turn plumping and hydrating the skin. Research also shows that Urea has a mild exfoliating action on the skin, encouraging the removal of dead cells which results in smoother, healthier, more hydrated skin.

valine

Calcium pantothenate is the salt of pantothenic acid, a form of Vitamin B5. Its main benefit in cosmetics is as a humectant, meaning it can draw water molecules to it, hydrating and plumping the area it has been applied to.

Pantothenic acid also supports the natural lipid barrier of the skin, by encouraging the production of a precursor to fatty acids & sphingolipids, both of which are essential parts of the skin barrier. This mechanism helps to moisturise the skin by reducing trans-epidermal water loss (TEWL), therefore retaining more moisture within the skin. This also helps to reduce inflammation in dry or broken skin, as an intact skin barrier will prevent potential irritants from getting into the epidermis.
