fatty acid
Fernblock
Known as FernBlock, this is a patented active from Heliocare, developed alongside Harvard medical school. It is derived from a tropical fern native to South America, and works by protecting against UVB-induced sunburn, as well as protecting against UVA and Infrared wavelengths. The active is also able to support cell renewal and protect from cumulative damage caused by sun exposure (such as ageing and DNA damage). It is an antioxidant, protecting against free radicals, and has been shown to boost production of collagen, elastin and hyaluronic acid in the skin.
Ferric hexapeptide is an anti-ageing peptide and is used in skincare to treat fine lines and wrinkles. It is in a class of ingredients also found on ingredients lists as acetylarginyltryptophyl diphenylglycine, acetyl tetrapeptide, arginine/lysine polypeptide, azelaoyl bis-dipeptide, copper heptapeptide-14 pantothenate, dipeptide, dipeptide diaminobutyroyl benzylamide diacetate, 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.
Ferulic Acid
Ferulic acid is a naturally occurring acid found in plants, such as bran. It is used in skincare for its antioxidant properties, meaning it can neutralise free radicals before they can cause any cellular damage. It has also been shown to stabilise Vitamins C and E when used in combination, resulting in a boost in their efficacy vs being used without the addition of Ferulic acid.
Feverfew has been used in ancient medicine for centuries to treat everything from headaches, constipation, vertigo, worms, spasms & arthritis. One of the oil-soluble flavonoids, Tanetin, has been shown to modulate inflammatory responses in the body, whilst other flavonoids provide antioxidant protection.
Fomes Officinalis (Mushroom) Extract
Fomes officinalis is in a class of ingredients also known as mushroom extract and polyporus umbellatus (mushroom) extract
Fructooligosaccharides
Fructooligosaccharides are in a class of prebiotic ingredients also found on ingredients lists as alpha-glucan oligosaccharide, fructooligosaccharides, lactobacillus extract filtrate, rhamnose and saccharomyces cerevisiae (yeast) extract. Prebiotics are a class of ingredients which can be found on ingredients lists as alpha-glucan oligosaccharide, lactobacillus extract filtrate, rhamnose and saccharomyces cerevisiae (yeast) extract.
Ginkgo Biloba is a tree native to Asia, one of the oldest plant species on the planet, and rich in flavonoids and terpenoids. These provide powerful antioxidant protection, reducing potential damage caused by reactive free radicals. Studies have also shown Ginkgo Biloba to provide skin-smoothing and hydrating properties.
ginkgo biloba extract
Gluconolactone is a poly hydroxy acid (PHA). PHAs work by gently dissolving the keratin that binds our outermost layer of skin cells, encouraging the natural exfoliation process of the skin, leading to smoother, clearer skin. This process also encourages new skin cell generation in the basal layer of the epidermis, a process which naturally slows with age, so with repeated use this can have an overall anti-ageing effect on the skin. Gluconolactone has also been shown to inhibit the enzyme elastase, which breaks down elastin in the skin (an essential protein produced by the fibroblasts), leading to sagging of the skin. PHAs are much larger in molecular weight vs AHAs so they cannot penetrate the skin as fast or as far, which therefore makes more gentle & suitable for more sensitive skin types, including those with rosacea-prone skin. Gluconolactone is also especially good for drier skin types as it also has natural humectant qualities, meaning it draws water towards it, hydrating the skin from within. Gluconolactone is in a class of polyhydroxy acid ingredients also known by lactobionic acid, and maltobionic acid.
glutamic acid
A non-essential amino acid used in skincare as a skin conditioning agent.
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 its high performance and broad availability (making it very cost-effective). Recent research has shown that its 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.
Glyceryl Glucoside is used in skincare for its 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.
Glycine
Glycine is an amino acid that is found in glycerine and collagen, which are ingredients in many skincare products. Glycine can improve the visible signs of aging, moisture retention, collagen production and regeneration. 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.
Glycolic acid is an alpha hydroxy acid (AHA), derived from sugar cane. 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. Glycolic acid has the smallest molecular weight of all the AHAs, meaning it can penetrate the skin quickest, producing the fastest results, but also most likely to cause skin sensitivity, so it is best for those with fairly tolerant skin types.
