Normal skin is characterized by neither feeling dry nor oily, but rather soft, supple and resilient. Normal skin has small pores and is rarely affected by pimples or other skin conditions. However, by treating your skin in the wrong way, perfectly normal skin can transform into dry, sensitive or irritated skin so be nice to your biggest organ and treat it gently.

Dry skin is characterized by a lack of the appropriate amount of water in the most superficial layer of the skin, the epidermis. The skin tends to get dryer with age and environmental factors, such as humidity and temperature, have a profound effect on the dryness of the skin. Dry skin has a greater need for help than normal skin does and can become sensitive and perceived as tight and irritated.

Oily skin is a common skin type which can affect both women and men from puberty up to the age of sixty. The texture of the skin is the result of excessive sebum production, which can make it look greasy and shiny with oversized pores as a result. Oily skin can sometimes cause blackheads or pimples. According to research, higher oil content in the skin results in fewer wrinkles, so don't worry about your oily, glossy skin!

A combination skin type is a mixture of normal/dry skin and oily skin. Often, people with combination skin feel oily in the area between the forehead, nose, and chin (T-zone), while the skin on the cheeks is dry or normal. A person with combination skin can benefit both from products for oily skin as well as dry skin.

There is no standard definition for sensitive skin. The typical description of the experience is that the skin itches, burns or stings. It could also be that you “feel your skin” all the time, which may then be a sign of sensitivity. Other symptoms of sensitive skin are that the skin reacts to certain ingredients that may be found in cosmetic or skincare products. It can become flammable, scaly and irritated.
