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.
Zinc PCA
Zinc PCA is a component of the skin’s natural moisturising factor (NMF), which acts as a humectant to draw water to it, and when synthesized with zinc, it can actually improve the efficacy of zinc, by making it more bioavailable and easily-absorbed. Studies have also shown that zinc PCA can inhibit the activity of destructive enzymes within the skin, therefore providing a protective, anti-ageing mechanism to the skin. Zinc is a family of ingredients that can also be found on ingredients lists as zinc gluconate, zinc sulfate and zinc sulphate.
Butyl Methoxydibenzoylmethane
Butyl Methoxydibenzoylmethane / Avobenzone is a synthetic sunscreen filter used in skin care to protect against damage from UVA light. Other ingredients in the class of synthetic filters include bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl salicylate, ethylhexyl triazone, homosalate, octinoxate, octisalate, octocrylene and triazine diethyl butamidotriazone.
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. it is a family of ingredients also seen on ingredients lists as potassium lactate.
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.
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.
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.
Vitamin C has many skin benefits, including its action as an antioxidant, to neutralise free radicals (reactive molecules with an unpaired electron), preventing them from causing damage to cells within the body. Vitamin C is also involved in the collagen-production process, so provides anti-wrinkle activity through this mechanism. Lastly, Vitamin C inhibits the enzyme tyrosinase, which is involved in melanin-synthesis, and can therefore visibly reduce areas of hyperpigmentation in the skin. Vitamin C is a family of ingredients also known as ascorbic acid, ascorbyl glucoside, ascorbyl palmitate, ethyl ascorbic acid, l-ascorbic acid, magnesium ascorbyl phosphate, sodium ascorbyl phosphate and tetrahexyldecyl ascorbate.
Endothelyol
Endothelyol is used in skincare to target redness and rosacea. It provides a soothing effect by regulating inflammatory processes in the skin, as well as reducing visible redness via encouraging microcirculation (blood flow in the capillaries). It has been proven to reduce rosacea symptoms after 28 days daily use.
Pyrus Malus (Apple) Fruit Extract
Apple extract, also known as pyrus malus extract, is used in cosmetics for its antioxidant abilities, as it is very high in polyphenols. This means it is able to help protect the skin from free radical damage, one of the largest external factors which contributes to ageing of the skin (after UV light).
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.
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.
Euterpe Oleracea Fruit Extract
Acai is a plant ingredient which can also be referred to by its botanical name, euterpe oleracea. It displays potent antioxidant abilities, meaning it is able to protect skin against free radical damage.
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.
Bisabolol
Bisabolol is a naturally-occurring active found in the chamomile plant, although it can also be created synthetically. Its key properties are as an anti-inflammatory and soothing agent, with some studies also showing it to have a brightening effect on the skin. Bisabolol is a rich source of panthenol (vitamin B5), which acts as a humectant, meaning it draws water molecules towards it to plump and hydrate the area. Studies have also shown that bisabolol can enhance the penetration of other actives into the skin, so is great when used in combination with other actives designed to work at the basal layer of the epidermis, or in fact the dermis.
