Skin Types - What type of skin do you have?

To create perfect skin you have to treat each individual cell within it perfectly. You need to know if the cell needs more water, less oil - or just leaving alone to calm down and stop getting hot and bothered.

The only way you're going to do this is to know your skin type. Now, you may think you know this already, but many of us are wrong.

For starters, skin types change with age, so oily skin in your teens doesn't mean oily skin in your twenties, thirties or forties.

Skin types can also change with the seasons, as temperatures affect the levels of oil and water in the skin; they can change with your diet, and even according to the time of the month.

So to truly know your skin type, you have to reassess it regularly. Doing so is easy - just answer the following questions and see which letter you choose most often.
