Helps to form a protective barrier on the skin and soothe skin irritation.

Benefits

Helps protect skin: Zinc oxide form a protective barrier on the skin and helps mitigate the effects of bacteria and other irritants on the skin.

Helps soothe skin irritation: Zinc oxide is also used to help prevent dry flaky skin. The antibacterial properties make it a common ingredient in antiseptic ointments to help relieve itchiness, and to help protect irritated skin.

Products that contain Zinc Oxide

A silicone that helps to protect the skin by forming a water-repellent barrier against water soluble irritants.

Benefits

Helps protect skin: Its thick, viscous nature, makes for an excellent barrier on the skin to help prevent chaffing, nappy rash and other forms of skin irritation caused by friction and exposure to water-soluble irritants.

Occlusive and moisturising: The ability of Dimethicone to form a barrier on the skin also makes it effective for use as an occlusive. Occlusives help prevent moisture in the skin from evaporating.

Products that contain Dimethicone

A humectant, helping to draw and hold water to the skin to maintain hydration.

Benefits

Excellent skin moisturiser and conditioner: Moisturisers containing glycerin can produce long-lasting moisturisation by minimising water loss5.

Helps protect against irritation: 10% Glycerine in a topical emulsion can help prevent the irritation and dehydration effects of washing the skin, including when Sodium Lauryl Sulphate is used as the detergent6.

Helps to retain moisture in the skin: At high humidity, Glycerine acts as a humectant, while at low humidity it acts as a skin moisturiser and conditioner by inhibiting lipid phase transition6.

A mild exfoliant that helps to remove dead, outer skin while improving skin moisture.

Benefits

Increases skin exfoliation: Lactic Acid has been shown to increase skin exfoliation in conjunction with its skin renewal activity7. It has been hypothesized that this is the result of the dissolution of the protein linkages between the skin cells7. Once the cells are detached from the body of the skin they are sloughed off.

Decreases the formation of dry skin: AHAs in general increase plasticization and decrease the formation of dry, flaky scales on the skin’s surface8.

Moisturising: AHAs have been shown to reduce transepidermal water loss9 improving the water content of the skin. AHAs have also been found to improve skin texture, improve skin brightness, improve firmness and decrease wrinkling8.

Otherwise known as Nicotinamide or Vitamin B3, helps maintain normal skin barrier function and reduce sensitivity, as well as moisturising dry skin.

Benefits

Helps maintain normal skin barrier function and reduces skin sensitivity: Topical application of 2% Nicotinamide has shown to improve the barrier properties of the skin and reduce skin sensitivity10.

Helps to moisturise dry skin11: The topical application of 2% Nicotinamide is shown to significantly reduce transepidermal water loss.

Helps to improve the appearance of skin tone and texture12: Topical application of 5% Nicotinamide was shown to improve the appearance of aged and photodamaged skin and a reduction in hyperpigmentation12.

Also known as Pro Vitamin B5, helps to improve skin hydration and reduce water-loss to maintain softness and elasticity.

Benefits

Penetrating: When Panthenol is applied to our skin, it results in a conversion to Pantothenic Acid. This acid penetrates into the epidermis, because it is readily absorbed by the skin13.

Protecting: Penetrates the stratum corneum to promote lipid synthesis and improves the barrier function of the skin14. Panthenol helps relieve systemic itching, whilst also helping to soothe dry and irritated skin14.

Hydrating: Pantothenic Acid works as a humectant, by attracting the moisture via absorption and retaining that moisture deep within the skin14.

An emollient that helps to reduce moisture loss from the outermost layer of the skin to maintain hydration.

Benefits

Safe for prolonged use: Critical analysis of studies into the toxicity of mineral oils such as Paraffinum Liquidum has shown that it is safe for prolonged use15.

Rarely causes allergic reactions: Allergic reactions to Paraffinum Liquidum are infrequent considering its widespread use in topical products16.

Non-comedogenic: Highly refined and purified mineral oils, such as Paraffinum Liquidum found in cosmetic and skincare products are non-comedogenic17 (does not clog pores).

Highly efficacious moisturising ingredient: Paraffinum liquidum keeps the skin moist and supple by providing a protective film and controlling the passage of water into and out of the skin18.

A highly effective emollient, used to promote both short- and long-term skin rehydration.

Benefits

Contributes to skin barrier properties: It penetrates the uppermost stratum corneum layers, passing into the intercellular phase. Rather than integrating with the natural intercellular layer, it is distributed throughout the stratum corneum as a separate phase, thus contributing to the skin’s natural barrier properties19.

Reduces transepidermal water loss: The application of petroleum jelly to the skin in vivo can immediately reduce transepidermal water loss by 40-50%20.

Low irritancy rating: Widely recognised as being innocuous and non-allergenic21. Only rarely are sensitisation reactions reported22 and petrolatum presents few, if any, safety or toxicological problems23.

Promotes skin hydration and skin suppleness, as well as supporting skin barrier function.

Benefits

Moisturising: Safflower Oil is an occludent moisturiser24 which assists in reducing the effect of moisture loss25.

Anti-inflammatory: Chemically induced irritant and allergic contact dermatitis has been shown to be relieved by the topical application of Linoleic Acid26.

Skin renewal: The topical application of Linoleic Acid has been shown to promote skin renewal by increasing the turnover of the stratum corneum27. The topical application of Linoleic Acid has also been found to correct excessive DNA synthesis, and the related excessive thickening of the skin (acanthosis, hypergranulosis, hyperkeratosis), thus returning the skin to its normal condition28.

Anti-acne: It has been found that the topical application of a 2.5% Linoleic Acid gel to mild acne, reduced the size of follicular casts and microcomedones, with an overall size reduction of 25% achieved in a 1 month period29.

A fast-soluble vitamin and antioxidant that helps to repair, protect and smoothe sensitive skin.

Benefits

Helps repair, protect and smoothe skin: Vitamin E has been found to help protect from UV-induced erythema36-37 and roughness38, improve the appearance of age spots, increase elasticity and skin barrier function39, and smooth fine lines and wrinkles41.

Anti-pruritic: Topical Vitamin E has also been found to reduce irritation related itch38.

Antioxidant: Vitamin E has been shown to be beneficial in preventing UV-induced free radical formation, protecting endogenous epidermal antioxidants and preventing lipid peroxidation40-41. In addition, studies have shown that Vitamin E can reduce UVB induced erythema41, and wrinkling42-43.
