A common question for those integrating light therapy into their evening routine is how it interacts with potent "actives" like Retinol or Vitamin C. While light therapy is non-invasive, timing is the key to safety and efficacy.
Because certain skincare ingredients can increase the skin's photosensitivity, a "Light First, Active Second" protocol is generally recommended. By using an LED device on clean, dry skin, the light can penetrate directly without interference from heavy creams or barriers. Once the session is complete, you can apply your serums or Retinol. This sequence ensures you receive the benefits of the light while minimizing the risk of irritation. Consistency is the most important factor: using your device daily as part of a structured ritual is the most effective way to see cumulative results over time.
