What do occlusives do?

Explanation:
Occlusives work by forming a barrier on the skin that blocks water from escaping. This barrier reduces trans-epidermal water loss, keeping the skin hydrated, which is why preventing moisture evaporation is the best description. They don’t primarily absorb water (that’s the role of humectants), and while the film they form can improve the feel and may help with friction in some cases, their main function is to prevent evaporation.
