Final answer:
The two skin types that have similar levels of hydration are normal and combination. Occlusives create a barrier on the skin's surface to prevent water loss, and humectants attract water to the skin and help retain moisture.
Step-by-step explanation:
The two skin types that have similar levels of hydration are Normal and combination. Oily and dry skin types have different levels of hydration. Sensitive and mature skin types may have different levels of hydration as well.
Occlusives are moisturizers that create a barrier on the skin's surface to prevent water loss. They trap moisture in the skin by forming a thin film. Examples of occlusives include petroleum jelly and mineral oil.
Humectants are moisturizers that attract water to the skin and help to retain moisture. They work by drawing water from the environment or from deeper layers of the skin. Examples of humectants include hyaluronic acid and glycerin.
