Cool modifiers are those which contain a significant amount of cool yellow or green. They are typically used to cool an existing colour or to correct a brow that is too warm.

Tips for using Cool Modifiers: 

• Cool modifiers are very strong, very little is required
• When unsure if you should use a cool modifier, it is safer to add a cool colour instead 
• Adding a dot of modifier on a toothpick controls the amount added better than a drop from the bottle
• Light-handed work will rarely require a modifier when the correct colour is selected to begin with
• Microblading aged/thin skin (though not the best technique for this skin type) will likely require a warm modifier
• Microblading ruddy/red skin (though not the best technique for this skin type) will likely require a warm modifier
