It might sound incredibly complex but there is an easy way to find out your skin type. Cleanse your skin with a basic cleanser or face wash, gently pat dry and then leave it for about 30 minutes to an hour. Try not to touch your skin as you want to see how it has reacted to being cleansed in order to determine your skin type.
How your skin looks and feels after this time will determine its type. For example; if your skin looks greasy then your skin type is oily but if it looks blotchy and feels sore or irritated then you have sensitive skin.
