Jeju Green Tea Water

Jeju green tea water works to hydrate the skin, whilst offering antioxidant protection through the high concentration of polyphenols present in the green tea.

Retinol

Retinol

Retinol, is a part of the vitamin A family of ingredients and is one of the most well-researched actives used in skincare today. Retinol and all of its derivatives are broken down within the skin first into retinaldehyde, then into retinoic acid, the active form recognised by the body to trigger its skin benefits. 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. It is part of a family of ingredients also found on ingredients lists as encapsulated retinaldehyde, hydroxypinacolone retinoate, retinaldehyde, retinyl palmitate, retinyl propionate and retinyl retinoate (8x more powerful than retinol)

Threonine

Threonine

When taken orally, it helps the digestive and intestinal tracts function more smoothly and also helps the absorption of nutrients. As for skincare, it helps to hydrate the skin. 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, leucine, lysine, proline, serine, taurine and valine and yeast amino acids.

Fernblock

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.

Isoleucine

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.

Homosalate

Homosalate

Homosalate is a synthetic UV filter used in sun care products to provide UVB protection against the wavelengths 295-315 nm. Other ingredients in the class of synthetic UV filters include bis-ethylhexyloxyphenol methoxyphenyl triazine, butyl methoxydibenzoylmethane, ethylhexyl salicylate, ethylhexyl triazone, octinoxate, octisalate, octocrylene and triazine diethyl butamidotriazone.

Mineral UV Filters

Mineral UV filters are naturally-occurring mineral powders, used in sun protection products to absorb UV light. They work predominantly by absorbing UV rays, like their synthetic/chemical counterparts, with only about 5% of UV rays reflected. There are currently two mineral UV filters on the market: zinc oxide and titanium dioxide.

Palmitoyl Tripeptide-1

Palmitoyl tripeptide-1 is a synthetic fatty acid-linked peptide that can help repair visible skin damage and strengthen skin’s underlying supportive elements. It is from 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 nonapeptide, palmitoyl oligopeptide, palmitoyl pentapeptide, palmitoyl tetrapeptide, pentapeptide, sh-oligopeptide, tetrapeptide and copper palmitoyl heptapeptide.

Guarana Extract

Guarana extract is derived from the seeds of the guarana plant (Paullinia cupana), which is native to the Amazon rainforest. It is used in skincare for its potential energizing, antioxidant, and skin-conditioning properties.

Luffa Cylindrica Extract

Lecithin

Lecithin

Lecithin can be classed as a phospholipid, which occurs naturally in eggs, soybean, sunflower oil and corn. It contains a high concentration of fatty acids, which support the skin’s natural barrier by creating a lipid film to prevent transepidermal water loss (TEWL). Lecithin also has lipophilic & hydrophilic properties, meaning it can function as an emulsifier and skin penetration-enhancer, helping to deliver actives deeper into the skin. Lecithin is in the class of essential lipids, and can be found on ingredient lists as caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, linoleic acid, linolenic acid, phospholipids and phytosphingosine.

Fructooligosaccharides

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.

Mango Seed Butter
