LED light should be applied slowly around each of the six zones for how long?

• A. 30 seconds
• B. 2 minutes
• C. 5 minutes
• D. 90 seconds

Answer: (B)

In LED facial treatments, each zone is given a precise amount of time to deliver a consistent, safe energy dose across the entire face. Treating every one of the six zones for a specific duration helps ensure the tissues receive enough photon energy to stimulate cellular responses without overheating. Two minutes per zone is the best choice because it provides a sufficient exposure to achieve the desired effects while keeping temperature and comfort within safe limits. Shorter times, like thirty seconds to a minute, may not deliver enough energy to be effective. A longer duration, such as five minutes per zone, increases the risk of overheating, irritation, or unnecessary energy exposure. One hundred ninety seconds is still typically less than the standard protocol, so two minutes per zone balances efficacy and safety. For context, this approach also means a total session length around twelve minutes for six zones, assuming even timing across zones, which helps maintain a uniform treatment effect.
