Sensitive skin terminology
Some of the terminology used when talking about sensitive skin, products and ingredients can be very confusing. So here’s a little break down of all the key terms to help you makes sense of sensitive skin.
Dermis - The dermis is a layer of skin below the epidermis and consists of connective tissue and cushions the body from stress and strain.
Sensitivity – this is a result of a reaction to something.
pH balanced –Human skin has a pH of 5.5. Pure water has a pH very close to 7. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. pH balanced means that the formulation has been carefully produced to ensure it’s suitable for skin.
Allergen - An allergen is any substance that can cause an allergy.
Irritant – something (e.g. an ingredient) which causes skin to become inflamed or painful.
Rash - A rash is a change of the skin which affects its colour, appearance or texture. A rash may be localised in one part of the body or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell and may be painful.
Hypoallergenic – a cosmetic or product which has been formulated specifically for skin which tends to be sensitive to reduce the chance of reaction.
Dermatology - the branch of medicine dealing specifically with skin and its diseases. A doctor who specialises in this area is called a Dermatologist.
Dermatologically tested – this means a product has been tested by a qualified dermatologist to ensure it is safe for use on skin. All Simple products are dermatologically tested.
