Encapsulation

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Encapsulation — a formulation technique in which an active ingredient is enclosed within a protective carrier or shell before being added to a product. This can help stabilize sensitive ingredients, control how and when they are released into the skin, and in some cases improve their delivery.

Key points

  • Encapsulation surrounds an active with a protective material such as liposomes or other carrier systems.
  • It can help shield ingredients that are prone to breaking down from light, air, or water.
  • Controlled or gradual release can reduce irritation from potent actives like retinoids.
  • The technique may also improve how well certain ingredients are delivered into the skin's upper layers.

Frequently asked

Why are skincare ingredients encapsulated?

Encapsulation can protect unstable ingredients from breaking down and allow them to be released gradually into the skin. This may improve stability and reduce irritation from stronger actives.

Does encapsulation make ingredients more effective?

It can improve stability and delivery for certain ingredients, and gradual release may reduce irritation. Actual results depend on the specific ingredient and formulation.
