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.

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.

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.

Dioic Acid

Octadecenedioic Acid

Dioic acid is a naturally-occurring acid found in plant and animal fats/oils. It is used in skincare for its ability to regulate sebum production in the skin, as well as its antibacterial action against acne-causing C. Acnes bacteria. It has also been shown to visibly reduce hyperpigmentation, with results being comparable to that of hydroquinone (the gold standard prescription for treating hyperpigmentation).

Polyhydroxy Acids

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.

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.

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.

Spent Grain Wax

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.

Acetyl Glucosamine

Acetyl Glucosamine

Acetyl Glucosamine is an amino acid sugar. It increases hyaluronic acid production in the skin, repairs sun damage, improves skin tone & hydration, and reduces the appearance of wrinkles. Amino acids are a class of ingredients. They can also be found on ingredients lists as acetyl tyrosinamide, alanine, arginine, arginine hcl, arginine pca, glycine, histidine, isoleucine, lysine, phenylalanine, proline, serine, taurine, threonine and valine and yeast amino acids.

Willow Herb Extract

Willow Herb Extract

A botanical extract used for its antioxidant and skin-soothing abilities.

Lactic Acid

Lactic acid is an alpha hydroxy acid (AHA), which occurs naturally in the body, as well as being found in dairy products, but is typically derived synthetically for cosmetics today. 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. it is a family of ingredients also seen on ingredients lists as potassium lactate.

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.

Tasmanian Pepperberry Extract

Tasmanian Pepperberry Extract

This natural berry is high in antioxidants, to help protect against free radical damage, and also has anti-inflammatory properties to soothe and calm.

Vitamin E

Vitamin E is a fat-soluble Vitamin contained in many plant oils, or can also be produced synthetically. Vitamin E is found naturally in our own skin, and its main benefit is to offer powerful antioxidant protection against pollution and free radical damage. It also helps to support our skin’s natural lipid barrier, which in turn improves the hydration levels within the epidermis, as water loss through the skin is minimised. Vitamin E is a family of ingredients also known as alpha tocopherol, tocopherol acetate, tocopheryl (vitamin e) acetate, tocopheryl glucoside or tocopheryl linoleate/oleate.

Glycerin

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.

Centella Asiatica

Centella Asiatica

Centella asiatica promotes wound healing and skin repair, helping to accelerate the recovery process. It exhibits anti-inflammatory effects, reducing redness, irritation, and inflammation and provides soothing and calming benefits, making it beneficial for sensitive or compromised skin.
