   Fast Absorption
   New in 2015
  Fast Absorption
  means “Skin Care
Compatible with my skin”
 
     
 
   “Fast Absorbing”
 
 
Fast absorption is one of
important desirable
features of skin care
 
 
   
Fast Absorbing Hand Cream instantly absorbs into
skin and leaves behind only the comfort of perfectly
soft, supple, smooth hands.
Non-greasy  
Lightweight  
Fast-absorbing  
Dermatologist developed  
 
Vaseline® Men Healing Moisture Fast
Absorbing lotion is specifically engineered
to moisturize and help protect even the
most sensitive, dry skin from the elements.

Made with micro-droplets of Vaseline®
Jelly and powerful moisturizers that
absorb deeply to moisturize and heal your
skin from within.*

Fast acting, non-greasy healing moisture
for healthy resilient skin.

 
 
 
     
 
 
Absorption Ratings of Carrier Oils
 
These common carrier oils are used in cosmetics, bath and body
products. It is nice to know how these ingredients rate for
absorption, especially if you are planning to include them in
homemade products. If you are not a wildcrafter, it’s still a
good way to educate yourself about the ingredients found in the
products you buy and use. This is by no means a
comprehensive list but some that we were most interested in
here.
 
The oils are rated using the folowing scale.
 
1 - Very Fast Absorption Rate
Considered a “drying oil” - quickly absorbed by the skin and
does not leave an oily feel.
 
 
2 - Fast Absorption Rate
Feels light and absorbs into the skin readily. Leaves a silky,
smooth finish.
   
3 - Average Absorption Rate
Leaves a satiny finish on skin.
 
   
 
4 - Slow Absorption Rate
May feel sticky or waxy before warming at body temperature.
Leaves a slight oily residue on the skin.
 
 
5 - Very Slow Absorption Rate
May need to be heated for application. Feels heavy and leaves
an oily, protective barrier on the skin.
