Explore breakdowns of the skincare ingredients featured in our personalised Renude routines. Learn their benefits, functions, and who they're suitable for.
Tartaric Acid
Tartaric acid is an alpha hydroxy acid (AHA) which works to exfoliate the top layer of the skin. This helps to remove dead skin cells which might be blocking the pores, which in turn reduces the instances of blemishes and breakouts.
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.
Spent Grain Wax
Spent Grain Wax is a natural wax derived from the spent grains of malted barley, typically leftover from the brewing process in beer production. In skincare, it is used for its potential emollient, moisturizing, and skin-conditioning properties.
Apple Polyphenols
Apple (like most plants), contains polyphenols, which are compounds with strong antioxidant properties, meaning they are able to protect skin from free radical damage.
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.
Helianthus Annuus
Sunflower oil is a rich natural source of Vitamin E, a skin-moisturising antioxidant. This oil is also rich in linoleic acid (Omega 6), an essential fatty acid which works to nourish the skin, support the natural barrier, and provide some anti-inflammatory benefits.
Arginine
Arginine is an amino acid that can be found in food sources such as almonds and chocolate. Arginine is an essential amino acid that the body cannot produce on its own. It is often referred to as the ‘master amino acid’ and has a number of benefits to skin health. 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, glycine, histidine, isoleucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.
Copper PCA
A skin-conditioning agent which is also thought to help firm the skin and stimulate collagen synthesis.
Avene Thermal Water
Avene thermal spring water is sourced from a natural spring in France. It spends 50 years travelling to this spring through mountainous rock, and contains the minerals calcium, magnesium and silica, which are particularly good for sensitive skin due to their soothing properties.
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.
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.
Palmitoyl Glycine
A key amino acid in the formation of collagen, this ingredient works to increase microcirculation, improving oxygen flow to the skin, as well as reducing inflammation to result in firmer skin and reduced wrinkle visibility.
Zinc
It is known to regulate sebum production, as well as inhibit the growth of the C. Acnes bacteria to improve acne symptoms. Zinc is a family of ingredients also known as zinc gluconate, zinc pca, zinc sulfate and zinc sulphate.
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.
Rosemary Leaf Extract
Rosemary Leaf Extract is derived from the leaves of the rosemary plant (Rosmarinus officinalis). In skincare, it is used for its antioxidant, anti-inflammatory, and soothing properties.
