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.

allantoin

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.

arginine

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.

glyceryl glucoside

glycine

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.

hyaluronic acid

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.

I have chosen this peptide-based serum to target the ageing concerns you mention. Loaded with various anti-ageing peptides, this works to reduce wrinkles and improve skin firmness and smoothness.

Acetylarginyltryptophyl Diphenylglycine is a synthetic tetrapeptide used in skincare for its firming abilities. It works by inhibiting the enzyme elastase, which breaks down elastin in the skin (the protein responsible for skin firmness and elasticity). This reduction in elastase allows for higher levels of elastin in the skin, which in turn leads to skin that looks firmer, tighter and restructured.

acetylarginyltryptophyl diphenylglycine

Many peptides function as anti-ageing ingredients in skincare, due to their ability to fit specific receptors in the body to trigger anti-ageing responses. This includes mechanisms like collagen production, cell regeneration or even blocking muscle contractions to smooth expression lines. Peptides are made up of amino acids, and are unique in shape, with a huge variety available to target specific responses in the body.

acetyl hexapeptide

dipeptide diaminobutyroyl benzylamide diacetate

histidine

Lactococcus Ferment Lysate is a post-biotic ingredient derived from Gram-positive bacteria, Lactococcus lactis. It is used in skincare for its ability to increase the speed of epidermal growth, leading to a thicker stratum corneum (outermost layer of the skin), and in turn better barrier function. This is seen as healthier-looking, more hydrated and supple skin.

lactococcus ferment lysate

Probiotics can be defined as living bacteria which are good for the skin, and are useful to include in skincare formulations in order to populate a healthy microbiome (the ecosystem of bacteria on the skin). 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.

palmitoyl tetrapeptide

pentapeptide

Sodium hyaluronate is the sodium salt of hyaluronic acid (a polysaccharide which occurs naturally in the body), created to improve the ingredient stability. It 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.

This simple moisturiser is a great option for you to add hydration to the skin and support the natural lipid barrier without clogging pores. It is packed with ingredients which occur as part of the natural moisturising layer of the skin, to help support surface hydration and keep skin healthy.

Linoleic is an Omega 6 essential fatty acid (EFA), found in many plant oils: corn, safflower & sunflower. Linoleic acid forms the fatty acid based of Ceramides EOH, EOS and EOP, which are essential for the normal functioning of the skin barrier. Applying linoleic acid topically helps to support ceramide functioning within the skin, leading to improved skin hydration and smoothness.

Research also shows that sebum in acne-prone skin can be lacking in Omega 6 (with too much Omega 3), so there is evidence to suggest applying this topically can help to balance the sebum composition and in turn reduce acne lesions.

linoleic acid

Our outer layer of the skin, the stratum corneum, has a multilamellar structure (essentially a fine membrane), made up of lipids (fats), to form a non-permeable barrier. This keeps water inside the skin, and acts as the first defense against external aggressors. The lipids which make up the majority of this are known as ceramides, which are produced naturally in the body from a range of other naturally-occurring lipids, which we class here as essential lipids (not the same as essential fatty acids, which are deemed ‘essential’ as the body cannot produce these naturally.) Using these lipids in skincare helps to support the natural skin barrier, preventing water-loss to keep skin hydrated and balanced.

Sodium lactate is a salt produced by the fermentation of lactic acid. It acts as a humectant in the skin, drawing water molecules from the atmosphere towards it to plump and hydrate. It is present in the skin’s natural moisturising factor (NMF), as both sodium and lactate. Studies have shown that lactate levels in the stratum corneum directly correlate with the hydration levels within the skin, with low levels resulting in dry, rough, flaky skin. Applying this ingredient topically helps the natural water-binding capacity of the epidermis, resulting in smoother, softer, more hydrated skin.
