Moisturizers
- Purpose: restore and maintain skin in a good-looking, fully moisturized condition
- Maintained by hydrating with water, followed by occlusives and humectants
- Occlusivity: reducing trans-epidermal water loss (TEWL) by slowing moisture vapor transmission rate (MVTR)
- Humectancy: materials that attract and bind water to the skin
- Typical humectants: glycerin, sorbitol, sodium lactate, and sodium pyrrolidone carboxylate
Types of Moisturizers
- Semi-solid emulsions (creams)
- Flowable emulsions (lotions)
- Five types of moisturizing products:
- All-purpose creams
- Hand and body lotions
- Hand and body creams
- Facial moisturizing lotions
- Facial night creams
All-Purpose Creams
- W/O emulsions or high-oil content O/W emulsions
- Heavy consistency, significant drag on rub-out
- Oil phase: 30-70%
- Characteristics: protective, treatment products, and resist wash-off
Hand and Body Lotions
- O/W emulsions
- Oil phase: 10-15%
- Humectant phase: 5-10%
- Water phase: 75-85%
- Characteristics:
- Easy flow and pumpability
- Fast rub-in
- Lack of stickiness after rub-in
- Instantly hydrate the skin
- Relieve dry skin symptoms
- Reduce MVTR
- Prolonged skin improvement
Hand and Body Creams

Facial Moisturizer Lotions
- Lower concentrations of occlusive agents and humectants than hand and body lotions
- Quick-breaking, instant-absorbing products with a matte finish
- Characteristics:
- Good moisturizing capability
- Reduce MVTR rates
- Immediate and short-duration effect on superficial facial lines
Facial Moisturizer Creams (Night Creams)
- Higher levels of occlusive and humectant materials than facial moisturizer lotions
- Lighter emollients, quick-breaking emulsions, and controlled levels of humectant materials
