Explore breakdowns of the skincare ingredients featured in our personalised Renude routines. Learn their benefits, functions, and who they're suitable for.
Phytic Acid
Phytic acid is technically an alpha-hydroxy acid (AHA), although its exfoliating effects are very mild compared to other acids in the AHA family. It does work to remove dead skin cell build up from the pores, and in turn reducing occurrences of breakouts, but this is not its main skin benefit. It is predominantly used for its high antioxidant potential, meaning it can neutralise damaging free radicals before they can cause any damage to the skin.
Phytosphingosine
Phytosphingosine (PS) is a lipid which naturally occurs in the stratum corneum (the top, visible layer of our epidermis). This acts as a precursor for ceramide synthesis, meaning it encourages the skin to produce ceramides naturally. Studies have also shown PS to offer anti-acne benefits, it is believed by reinforcing the protective barrier, and therefore reducing specific abnormalities in the skin functioning that lead to acne (invading inflammatory bacteria, increased keratinization, increased sebaceous gland activity). It is in the same class of essential lipids that include caprooyl phytosphingosine, caprooyl sphingosine, cholesterol, glycolipids, glycoproteins, glycosphingolipids, lecithin, linoleic acid, linolenic acid, and phospholipids.
Plankton Extract
Plankton Extract has nourishing and hydrating properties which can benefit those with dry skin, and its gentle nature makes it a fitting choice for individuals with 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, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, macrocystis pyrifera (kelp) extract, marine extract, parachlorella beijerinckii exopolysaccharides, parachlorella beijerinckii exopolysaccharides, porphyridium cruentum extract, pseudoalteromonas exopolysaccharides, tripleurospermum maritimum extract, vibrio alginolyticus ferment filtrate, chlorella protothecoides oil
Polyhydroxy acids (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 and with repeated use this can have an overall anti-ageing effect on 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. Polyhydroxy acids (PHAs) are a class of ingredients also known by gluconolactone, lactobionic acid, lactobionic acid (pha) and maltobionic acid.
Polyporus umbellatus (mushroom) extract is a type of medicinal mushroom used in skincare for its antioxidant and skin brightening properties.
Porphyridium Cruentum Extract
A type of red algae rich in polysaccharides, which helps to retain moisture and hydrate the skin. This ingredient has a smoothing effect and is very well tolerated by all skin types. The extract of red algae helps to enhance skin elasticity, which results in a reduction of lines and wrinkles. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, macrocystis pyrifera (kelp) extract, marine extract, parachlorella beijerinckii exopolysaccharides, parachlorella beijerinckii exopolysaccharides, plankton extract, pseudoalteromonas exopolysaccharides, tripleurospermum maritimum extract, vibrio alginolyticus ferment filtrate, chlorella protothecoides oil
Potassium Azeloyl Diglycinate
Potassium Azeloyl Diglycinate (PAD) is a water-soluble derivative of azelaic acid which conveys many of the same benefits as pure azelaic acid. It is a gentle anti-inflammatory so is suitable for sensitive skin, and is able to improve rosacea and acne symptoms, as well as fading pigmentation left from acne.
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.
Prickly Pear Extract
Prickly pear is a cactus native to Mexico, and is used in skincare for its soothing and hydrating properties. It is also known as hydrolyzed opuntia ficus indica flower extract and opuntia ficus-indica fruit 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.
Proline
A non-essential amino acid (meaning that our body can produce it) that's also one of the major building blocks of collagen. It is thought to be able to improve wrinkles when combined with other amino acids, glycine and leucine. 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, phenylalanine, serine, taurine, threonine and valine and yeast amino acids.
Pseudoalteromonas Exopolysaccharides
Pseudoalteromonas Exopolysaccharides are biotechnological marine alternatives to famous IT-moisturiser and humectant hyaluronic acid (HA). It is obtained by the fermentation of a marine bacterial strain. It is in the class of Algae Extract which also include ahnfeltia concinna extract, alaria esculenta extract, algae exopolysaccharides, algin, alteromonas ferment extract, ascophyllum nodosum extract, asparagopsis armata extract, chlorella protothecoides, chlorella vulgaris extract, dunaliella salina (green algae) extract, hydrolyzed f-fucoidan, laminaria ochroleuca (kelp) extract, macrocystis pyrifera (kelp) extract, marine extract, parachlorella beijerinckii exopolysaccharides, plankton extract, porphyridium cruentum extract, padina pavonica thallus extract, tripleurospermum maritimum extract, vibrio alginolyticus ferment filtrate, chlorella protothecoides oil
Quercetin
Quercetin is a naturally occurring bioflavonoid found in fruits and vegetables such as kale, onion, tomatoes and berries. It is used in skincare for its antioxidant abilities, meaning it can neutralise free radicals before they cause any damage to the skin. Studies also show Quercetin to have anti-inflammatory effects, and an ability to protect the skin against aggressors such as UV, histamine and toxic chemicals. It is also believed to support the skin barrier functioning, reducing water-loss via the skin to improve hydration levels in the epidermis.
Red Algae
Algae is an incredibly interesting natural ingredient source. It is essentially an underwater plant, designed to get its food from sunlight, much like any other plants, although from much more challenging conditions. There are many types of algae (kelp, laminaria, microalgae), but in general in all its forms it acts as a powerful antioxidant, protecting from free radical damage, as well as being able to hydrate the skin and deliver naturally-occurring vitamins into the skin.
Vitis Vinifera
Resveratrol is a family of ingredients also known as vitis vinifera (organic, cold pressed concord grape) seed oil, vitis vinifera (grape) flower cell extract, vitis vinifera (grape) fruit extract, vitis vinifera (grape) seed extract, vitis vinifera seed extract or vitis vinifera (organic). Most famously found in the skin of red grapes, but also occurring naturally in peanuts and certain fruits such as blueberries and cranberries. It is included in skincare for its powerful antioxidant abilities. Research shows it can protect against free radicals, as well as oxidative damage caused by UV.
