Perfecting Illumination is an organic emulsion that should be shaken before each use.
The first few pumps from a new bottle of Perfecting Illumination might be more liquid. After those initial pumps, remember to shake the bottle before each use to maintain a consistent texture.
If you have a sample of Perfecting Illumination, gently massage the sachet with your thumbs for 1-2 minutes to ensure even ingredient distribution.
