What is a moisturiser?
No matter if you have oily, dry, normal or combination skin your skin needs moisturiser.
There are three main types of moisturisers formulations:
Humectant
These compounds work to attract water from the dermis and rehydrate the epidermis. In environments with humidity higher than 70% they can also attract water from the environment to rehydrate the skin.
Emollient
Work to fill the crevices between exfoliating skin cells. They traditionally contain fatty ingredients to provide a protective blanket over the skin.
Occlusive Agent
An occlusive agent acts to prevent evaporation and water loss by the skin. To do so it forms a hydrophobic barrier. Occlusive agents are often very greasy and less favourable when applied to the skin.
A moisturiser should be applied accordingly to your skin type and condition. If you are a little drier your skin might suck in the moisturiser versus someone who is an oily skin type may only require a pea-sized amount.
What to avoid when choosing a moisturiser?
- Colouring and perfumes: these can contribute to irritation
- Antimicrobials: unnecessary additions of anti-microbials can strip the skin from naturally occurring oils and can be too harsh for the skin.
- Body moisturiser: tend to be more occlusive and can cause a breakout or flare of acne symptoms.
- Acid overload: using too many products which contain acids can lead to skin irritation and excessive dryness.
- Alcohol: can have a drying effect on the skin.
