Learn more about lipids with Professor Thomas M. Terry. Fats or triglycerides are formed by three fatty acids each bonded by an ester linkage to glycerol. 1  Twist and turn the lipid below to see how kinky fatty acids are.
Superficial peels are the mildest type of chemical peel. They can be used on all skin types. In most cases, they use liquid containing a mild (dilute) acid, most often glycolic acid. Dry ice (solid carbon dioxide) is sometimes used. Medium peels soak deeper into the skin than superficial peels do.
The chemical peel is a procedure where a chemical solution is applied to the skin that makes the top layers of skin âblisterâ and peel away, revealing newer skin underneath. A chemical peel usually involves approximately 5 to 7 days for recovery time. The results may last for at least a year or more and with continued sun protection far longer. The results last depending upon how deeply the skin was treated.
