Ingredients in Skincare

Explore breakdowns of the skincare ingredients featured in our personalised Renude routines. Learn their benefits, functions, and who they're suitable for.

Sesame Seed Oil

Sesame Seed Oil

Sesame Oil is a vegetable oil derived from sesame seeds (Sesamum indicum). In skincare, it is used for its moisturizing, antioxidant, and skin-nourishing properties.

Mandelic Acid

Mandelic Acid

Mandelic acid is an alpha hydroxy acid (AHA), derived from bitter almonds. 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. Mandelic acid has a larger molecular weight vs. other acids in the AHA category. It is twice the molecular weight of glycolic acid for example (the smallest AHA on the market), so it tends to be better tolerated than smaller AHAs, which penetrate the skin much faster. Research also shows that mandelic acid is particularly effective at improving some forms of pigmentation, compared with other AHAs.

Glyceryl Glucoside

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.

Prebiotics

Prebiotics, can be classed as a food source that encourages the growth of good bacteria on the skin. The microbiome (the ecosystem of bacteria on the skin) is a relatively new discovery and we are learning that this is linked to many different aspects of our health, mood and appearance. Prebiotics are a class of ingredients which can be found on ingredients lists as alpha-glucan oligosaccharide, fructooligosaccharides, lactobacillus extract filtrate, rhamnose and saccharomyces cerevisiae (yeast) extract.

Bisabolol

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.

Thiamidol

Thiamidol

An anti-pigment active discovered by Eucerin after researching the effect of 50,000 different compounds on their ability to inhibit human tyrosinase (which is involved in producing melanin, our skin’s pigment). Clinically proven to visibly reduce hyperpigmentation with just 2 weeks of use.

Tea Tree Oil

Melaleuca Alternifolia (Tea Tree) Leaf Oil

Tea tree oil is an essential oil extracted from the Melaleuca alternifolia plant, native to Australia. Tea tree leaf oil is known to have antibacterial qualities, the mechanism for this is not completely understood, but research shows that it could be due to an ability to damage the bacterial cell wall. It also has anti-inflammatory effects, due to its content of terpen-4-ol, which studies have shown reduces inflammation in the skin when applied topically. These functions make it a great ingredient for the use in acne treatments, both to kill C. acnes bacteria, but also reduce the associated inflammation.

Ceramides

Ceramides

Ceramides are a class of ingredients, which includes ceramide ap, ceramide 3, ceramide eop, ceramide eos, ceramide ng, ceramide np, ceramide ns and ceramide 6-ll. Their function 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. Applying ceramides topically can increase the levels of ceramides in the epidermis, and therefore supports the natural healthy functioning of the skin.

Soybean Extract

Bacillus/Folic Acid/Soybean Ferment Extract

Soybean extract is used in skincare for its powerful antioxidant potential. It is able to protect the skin from free radical damage. Research has also shown this extract to be able to visibly even out skin tone, and reduce the visible signs of ageing.

Natural Moisturising Factors

They are a substance produced by the body, made up of minerals, lactate, urea, amino acids & humectants, which coats the surface skin cells to keep them moisturised. NMF increases the skin’s ability to retain moisture, which results in more hydrated, plump, smoother skin. Natural moisturising factor (NMF) are a class of ingredients that can also be known by sodium lactate, sodium pca and trehalose.

Glycolic Acid

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.

Mushroom Extract

Mushroom extracts are derived from various types of mushrooms, such as shiitake, reishi, and chaga. In skincare, they are used for their potential anti-inflammatory, antioxidant, and skin-soothing properties. Studies have shown that compounds from specific mushroom types can inhibit tyrosinase activity (an enzyme involved in melanin synthesis), which in turn visibly minimises areas of hyperpigmentation. Mushroom extract is a class of ingredients also known by fomes officinalis (mushroom) extract, fomes officinalis (mushroom) extract and polyporus umbellatus (mushroom) extract.

Squalane

Squalane

Squalane is a natural substance usually derived from olives. It is structurally very similar to our skin’s own sebum, so is a great ingredient to support our own natural skin processes. In drier skin, which is naturally lacking in natural sebum, it helps to support the skin barrier to prevent water loss, which results in more hydrated, smooth and plump skin. Due to its sebum-mimicking structure, it is non-comedogenic, meaning it won't cause breakouts, so is also suitable for oily and acne-prone skin. It can be a great option to reduce any over-stimulation of the sebaceous glands, which can occur with excess cleansing (and make breakouts worse). It also works to support the skin barrier to combat any drying effects caused by ingredients commonly associated with acne treatment, so is a great ingredient for all skin types.

Green Tea

Camellia Sinensis Leaf Extract

Green Tea is a natural plant extract, rich in polyphenols, also known as catechins. Green Tea is particularly high in the catechin Epigallocatechin-3-gallate (EGCG), which is a powerful antioxidant, meaning it can neutralise free radicals to prevent them causing damage within the skin.

Apple Stem Cells

Malus Domestica Fruit Cell Culture Extract

Apple stem cells, also known as malus domestica fruit cell culture extract, occur naturally within plants to help regenerate cells after stress or injury, and studies show this can encourage similar regenerating mechanisms in human skin. Apple stem cells have been shown to increase synthesis of collagen & elastin to achieve visible anti-ageing results in the skin.
