What factor can affect the efficacy of laser treatments?

The efficacy of laser treatments can be significantly influenced by the skin hydration level of the patient. Proper skin hydration is crucial because it affects how the skin interacts with the laser light. Well-hydrated skin tends to absorb laser energy more effectively, which can enhance the treatment's outcomes. Hydration can also influence the skin's elasticity and permeability, which are important factors in how the laser penetrates and affects the underlying tissues.

When the skin is dehydrated, it may result in less effective absorption of the laser energy, potentially leading to suboptimal results or requiring additional treatment sessions. Therefore, maintaining proper hydration can maximize the effectiveness of laser treatments and is an essential consideration for practitioners when planning and administering laser therapies.
