Which factor can affect the laser treatment absorption in skin?

The hydration level of the skin is a significant factor that can affect laser treatment absorption. Water present in the skin plays a crucial role in determining how effectively the laser energy is absorbed by the tissue. When skin is properly hydrated, it maintains optimal moisture levels that enhance the absorption of laser energy, leading to more effective treatment outcomes. Conversely, dehydrated skin may exhibit reduced absorption rates, potentially diminishing the efficacy of the laser treatment.

Understanding the skin's hydration status is vital for practitioners, as it influences not only the absorption of the laser light but also the reaction of the skin to the treatment. Proper pre-treatment protocols often include recommendations for skin hydration to ensure better results during procedures. While other factors such as temperature, oiliness, and thickness can also influence absorption to an extent, hydration is particularly important because it directly affects the interaction between the laser and the skin tissue at a cellular level.
