Caprooyl Phytosphingosine
Caprooyl Phytosphingosine is a mixture of fatty acids Caproic acid and Phytosphingosine. It acts as a precursor for ceramide synthesis, meaning it encourages the skin to produce ceramides naturally. The function of ceramides is to hold the skin cells together by creating a barrier against water-loss from the inside-out, and external aggressors from the outside-in. They make up almost 50% of our skins composition, but they can be depleted by UV, free radicals & pollution, and their production also naturally slows with age. This leads to an impaired skin barrier, which results in dry, rough skin with more visible wrinkling and redness. Encouraging the skin’s natural production of ceramides leads to an improved skin barrier, resulting in smoother, more hydrated, younger-looking skin. Caprooyl phytosphingosine is in the class of essential lipids, it can be found on ingredient lists as caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, lecithin, linoleic acid, linolenic acid, phospholipids and phytosphingosine.
Mango seed butter, also known as mango kernel butter or mango butter, is a rich and creamy emollient derived from the seeds of the mango fruit (Mangifera indica). In skincare, it is used for its excellent moisturizing, nourishing, and skin-conditioning properties.
Glycosphingolipids are naturally occurring in the skin and are involved in the skin’s natural ceramide-production process. It in the class of essential lipids, and can be found on ingredient lists as caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, lecithin, linoleic acid, linolenic acid, phospholipids and phytosphingosine.
Chlorella Vulgaris Extract
In skin care products, algae extract has several functions, including as a thickening agent, water-binding agent, and antioxidant. Chlorella vulgaris extract has been shown to stimulate collagen synthesis. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, macrocystis pyrifera (kelp) extract, and marine extract.
Caprooyl Sphingosine
Caprooyl Sphingosine is a mixture of fatty acids Caproic acid and Sphingosine. It acts as a precursor for ceramide synthesis, meaning it encourages the skin to produce ceramides naturally. The function of ceramides is to hold the skin cells together by creating a barrier against water-loss from the inside-out, and external aggressors from the outside-in.

Jeju green tea water works to hydrate the skin, whilst offering antioxidant protection through the high concentration of polyphenols present in the green tea.
Vitamin K1 is a naturally occurring vitamin found in certain plants and algae.
Laminaria Ochroleuca (Kelp) Extract
A type of kelp that helps soothe skin and offers hydration-enhancing properties, it can also play a role in reinforcing skin’s barrier and warding off environmental stressors. Researchers note that this ingredient is particularly useful for those prone to sensitive skin. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, macrocystis pyrifera (kelp) extract, and marine extract.
Glycyrrhiza Glabra (Licorice) Root Extract
It has been shown to prevent and reverse UV-induced skin damage, to provide visible skin-lightening properties to the skin. Its second active component, glycyrrhetinic acid is used in skincare for its anti-inflammatory benefits. It works by inhibiting the production of inflammatory substances, such as cortisone, within the body, with some research showing results to be comparable to prescription hydrocortisone cream. Licorice is a family of ingredients and can also be known as ammonium glycyrrhizate, dipotassium glycyrrhizate (licorice), glycyrrhetinic acid, glycyrrhiza glabra (licorice) root extract, glycyrrhiza glabra root extract or glycyrrhiza inflata root extract.
Probiotics
Probiotics can be defined as living bacteria which are good for the skin, and are useful to include in skincare formulations in order to populate a healthy microbiome (the ecosystem of bacteria on the skin). A diverse breadth in the strains of bacteria living on the skin results in a healthy microbiome, and some early research has linked certain imbalances in this microbiome to skin conditions such as acne, eczema and psoriasis. Probiotics are a class of ingredients which can be found on ingredients lists as bifida ferment lysate, lactobacillus ferment, and lactococcus ferment lysate.
Retinyl Retinoate (8X More Powerful Than Retinol)
Retinyl retinoate is a part of the vitamin A family of ingredients, which combines retinol with retinoic acid. Research shows that this makes it more stable in the delivery (a common problem with either active alone), as well as more potent and less irritating. It is broken down by the body in two stages - first into retinol and retinoic acid, then the retinol is broken down again into retinoic acid, so essentially packing double the punch. Studies carried out comparing this to pure retinol showed significantly more effective and faster results, with comparable side effects. It is part of a family of ingredients also found on ingredients lists as encapsulated retinaldehyde, hydroxypinacolone retinoate, retinaldehyde, retinyl palmitate and retinyl propionate.
Saccharomyces Cerevisiae (Yeast) Extract
Yeast extract (e.g. Saccharomyces Cerevisiae) is used in skincare for its benefits as a moisturising and soothing agent. It has strong antioxidant properties to protect against free radical damage and its fermented nature means it also functions as a prebiotic on the skin (meaning it acts as a food source for beneficial skin bacteria to thrive). Prebiotics are in a class of ingredients that can be found on ingredients lists as alpha-glucan oligosaccharide, fructooligosaccharides, lactobacillus extract filtrate and rhamnose.
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.
Luffa Cylindrica Extract, also known as sponge gourd or loofah, is derived from the fruit of the Luffa cylindrica plant. In skincare, this extract is used for its potential exfoliating, cleansing, and skin-smoothing properties.
