Moisturising

Moisturisers are emulsions containing oil and water. These two ingredients do not mix. So, manufactures add emusifiers to stabilize them. There are basically two types of moisturisers:

  • Water-based moisturiser
  • Oil-based moisturisers

Two phases exist in emulsions- a continuous phase and a disperse phase. Water-based moisturisers (sometimes called oil-free moisturisers) are oil-in-water emulsions, which contain mostly water (the continuous phase) and some oil (disperse phase). Oil-based moisturisers, on the other hand have more oil (the continuous phase) and some water (the disperse phase).

Most moisturisers meant for the face are water-based because oil-based moisturisers tend to leave a greasy film on the skin. Water-binding ingredients such as urea, glycerin and sorbitol are often added to improve the water binding properties of water-based moisturisers. The consistency of the moisturiser often depends on its content of oil and glycerin. Light moisturisers (day cream) contain less and rich moisturisers (night cream) more. Light moisturisers soak quickly into skin and are usually applied during the day. Choosing the right moisturiser is keeping skin smooth while not clogging pores.

  • Day creams - these contain more water than oil and act to protect skin; they particularly suitable for oily skin
  • Night cream- these are richer and more oil, to feed sensitive and/or dry skin.
  • Lotion-these tend to be oil free and particularly suit combination skin types.

Sunscreen agents are sometimes added to moisturisers to protect the skin against sun damage. However, there is no reason why you should not use a sunscreen meant for the face as a day moituriser since most sunscreen contain moisturisers.
