Willow Herb Extract
A botanical extract used for its antioxidant and skin-soothing abilities.
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.
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.
N-Acetyl L-Tyrosinamide
Acetyl tyrosinamide is an effective moisturising ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl glucosamine, alanine, arginine, arginine hcl, arginine pca, glycine, histidine, isoleucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.
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.
Retinoic acid (aka tretinoin) is the gold standard of anti-ageing and works in a number of ways. Firstly, it blocks the production of collagen-degrading enzymes, meaning collagen does not get broken down as quickly in the skin. After prolonged use (6M+), it has also been shown to stimulate the production of type I and type III collagen, reducing wrinkles and improving skin firmness. It has been shown to protect against UV-induced damage, as well as reducing the appearance of hyperpigmentation in the skin. Skin treated with retinoids is smoother, more even-toned, firmer and younger looking. Vitamin A is a family of ingredients also known as retinol, retinaldehyde, encapsulated retinaldehyde, Retinoic acid (aka tretinoin), hydroxypinacolone retinoate, retinyl palmitate, retinyl propionate or retinyl retinoate (8x more powerful than retinol). Vitamin A is one of the most well-researched actives used in skincare today. Retinol and all of It's derivatives are broken down within the skin first into retinaldehyde, then into retinoic acid, the active form recognised by the body to trigger it’s skin benefits.
Prunus Serotina
Wild cherry is a natural fruit extract, rich in plant antioxidants and vitamin c which help to protect the skin from free radical damage. It may also offer skin calming benefits.
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.
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.
Tasmanian Pepperberry Extract
This natural berry is high in antioxidants, to help protect against free radical damage, and also has anti-inflammatory properties to soothe and calm.
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.
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.
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).
Cucumis Sativus (Cucumber) Fruit Extract
Cucumber extract, also known as cucumis sativus (cucumber) fruit extract, cucumis sativus or cucumber fruit extract, provides natural antioxidant protection against free radicals. It is comprised of 95% water, plus small concentrations of ascorbic acid (vitamin c), caffeic acid (an antioxidant), fatty acids and silica (mineral required for healthy skin, hair & nails).
Isoleucine
A branch-chained, essential amino acid that can be found in things like almond, cashew or soy protein. In skincare, it is used in moisturising products and is found to be good for skin barrier defence. Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl glucosamine,acetyl tyrosinamide, alanine, arginine hcl, histidine, arginine pca, leucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.
