Alaria Esculenta Extract

Alaria Esculenta Extract

A type of edible brown algae, harvested from waters bordering Europe and Ireland, and rich in amino acids, minerals and antioxidants. When used in skin care, it hydrates, soothes, and imparts the appearance and feel of firmness in the skin. The combined properties of the ingredient results in plump and hydrated skin, and reduced signs of ageing. It is in the class of Algae Extract which also include ahnfeltia concinna extract, algae exopolysaccharides, algae extract, algin, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, macrocystis pyrifera (kelp) extract, and marine extract.

Anti-Ageing Peptides

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 a class of ingredients also found on ingredients lists as acetyl hexapeptide, acetyl tetrapeptide, acetylarginyltryptophyl diphenylglycine, arginine/lysine polypeptide, azelaoyl bis-dipeptide, copper heptapeptide-14 pantothenate, dipeptide, dipeptide diaminobutyroyl benzylamide diacetate, ferric hexapeptide, heptapeptide-15, palmitate, myristol hexapeptide, myristol pentapeptide, myristoyl nonapeptide, myristoyl pentapeptide, oligopeptide, palmitoyl tripeptide, palmitoyl decapeptide, palmitoyl heptapeptide, palmitoyl hexapeptide, palmitoyl nonapeptide, palmitoyl oligopeptide, palmitoyl pentapeptide, palmitoyl tetrapeptide, palmitoyl tripeptide, palmitoyl tetrapeptide, pentapeptide, sh-oligopeptide, tetrapeptide and copper palmitoyl heptapeptide.

Hyaluronic Acid

Hyaluronic Acid

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 is a family of ingredients, also known by hydrolyzed hyaluronic acid, hydrolyzed hyaluronic acid, hydrolyzed sodium hyaluronate, sodium acetylated hyaluronate, sodium butyroyl hyaluronate, sodium hyaluronate or sodium hyaluronate crosspolymer.

Azelaic Acid

Azelaic Acid

Azelaic acid is found naturally in grains such as barley, wheat and rye, but can also be produced commercially in the lab. It has several benefits in skincare including as an anti-inflammatory, with evidence showing great results in treating rosacea symptoms (swelling & redness) via this mechanism. Azelaic also has an anti-blemish activity - firstly, it is an antibacterial which works to kill acne-causing bacteria, P.Acnes. Secondly, it prevents pores becoming blocked by the skin’s natural shedding process, which makes it harder for this bacteria to populate inside the pore to cause a blemish (it needs an oxygen-free environment to thrive). Studies have also shown azelaic acid to inhibit melanogenesis (production of melanin), so also has benefits in treating hyperpigmentation and post-inflammatory acne scarring. It has good skin tolerability, so can be used to treat more sensitive skin types in concentrations of around 10%. It is a family of ingredients, the other ingredient including Potassium Azeloyl Diglycinate.

Thiamidol

Thiamidol

An anti-pigment active discovered by Eucerin after researching the effect of 50,000 different compounds on their ability to inhibit human tyrosinase (which is involved in producing melanin, our skin’s pigment). Clinically proven to visibly reduce hyperpigmentation with just 2 weeks of use.

Salicylic Acid

Salicylic Acid

Salicylic acid works as an exfoliating acid to dissolve the keratin that binds the outermost layers of the skin, encouraging the natural exfoliation process of the skin. Salicylic acids are a family of ingredients and can also be found on ingredients lists as beta hydroxy acid (BHA) or capryloyl salicylic acid.

Niacinamide

Niacinamide, also known as Vitamin B3 and Nicotinamide, has many skincare benefits. Firstly, it regulates sebum production in the skin, which in turn reduces blemishes and visible pore size. It also reduces facial redness by improving microcirculation, which means moving the blood inside the capillaries away from the face to reduce visible redness. It also has the ability to strengthen the natural lipid barrier of the skin by encouraging ceramide production (the building blocks which seal our skin cells together), which in turn increases the hydration within the epidermis. Lastly, niacinamide works to help reduce hyperpigmentation by blocking melanin from being deposited on the skin cells.

Symsitive

Symsitive

This active has been designed specifically to soothe sensitive skin. Research from its manufacturer shows that 3 minutes after application, it can alleviate stinging by 78% and burning by 80%. It works by increasing the skin’s tolerance threshold to regulate the reaction response.

Teprenone

Teprenone

Teprenone, a synthetic active produced by manufacturer Sederma, is believed to provide all-round anti-ageing benefits by supporting the cells natural replication process, and preventing telomere lengthening in the process. Whilst the research is not robust enough to prove this, the study carried out showed promising in-vivo results after 1 month, with instrumental results showing an improvement in skin firmness, elasticity & tone. The same study also showed an improvement in skin smoothness and skin redness, as well as a reduction in pore size.

Perfluorodecalin

Perfluorodecalin

Perfluorodecalin is a synthetic active, used in skincare to dissolve and deliver oxygen into the skin. A lack of oxygen in the skin can cause unwanted bacteria to populate, for example in conditions like acne and rosacea. Adding extra oxygen into the skin, creates a hostile environment for these anaerobic (oxygen-hating) bacteria to survive.

Vitamin B5

Vitamin B5 is a humectant, meaning it can draw water molecules to it, hydrating and plumping the area it has been applied to. It 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. Vitamin B5 is a family of ingredients also known as calcium pantothenate, calcium pantothenate (vitamin b5), d-panthenol, pantothenic acid, panthenol, and panthenyl triacetate.

Aloe Vera

Aloe Barbadensis Leaf Juice

Aloe vera, also appear on ingredients lists as aloe barbadensis (aloe vera) leaf juice, contains around 75 active constituents, including Vitamins A,C & E to provide antioxidant protection, 8 enzymes to inhibit inflammatory processes in the body and 9 different minerals to support the body’s natural functioning. It also includes sugars to provide hydrating humectant properties, fatty acids to provide anti-inflammatory & antiseptic properties, and hormones to promote wound healing.

Acetylarginyltryptophyl Diphenylglycine

Acetylarginyltryptophyl Diphenylglycine

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. It is in a class of ingredients also found on ingredients lists as acetyl hexapeptide, acetyl tetrapeptide, arginine/lysine polypeptide, azelaoyl bis-dipeptide, copper heptapeptide-14 pantothenate, dipeptide, dipeptide diaminobutyroyl benzylamide diacetate, ferric hexapeptide, heptapeptide-15, palmitate, myristol hexapeptide, myristol pentapeptide, myristoyl nonapeptide, myristoyl pentapeptide, oligopeptide, palmitoyl tripeptide, palmitoyl decapeptide, palmitoyl heptapeptide, palmitoyl hexapeptide, palmitoyl nonapeptide, palmitoyl oligopeptide, palmitoyl pentapeptide, palmitoyl tetrapeptide, palmitoyl tripeptide, palmitoyl tetrapeptide, pentapeptide, sh-oligopeptide, tetrapeptide and copper palmitoyl heptapeptide.

Algae Extract

Algae Extract

It is essentially an underwater plant, designed to get its food from sunlight, much like any other plants, although from much more challenging conditions. In all its forms it acts as a powerful antioxidant, protecting from free radical damage, as well as being able to hydrate the skin and deliver naturally-occurring vitamins into the skin. Algaes are a class of ingredients, many of which can be used in skincare. Variants of algae used in skincare are ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella protothecoides oil (oleic acid), chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolysed algin, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, laminaria ochroleuca extract. macrocystis pyrifera (kelp) extract, and marine extract

Adenosine

Adenosine

Adenosine is a well-researched anti-ageing and soothing ingredient. It is produced naturally in the body, but can also be derived from yeast. It works by stimulating the skin's own collagen production process, to reduce the appearance of wrinkles. It also has anti-inflammatory and barrier repair benefits, so is a fantastic multi-functional skincare ingredient.
