Creating individualized treatment plans are important because no two clients are alike, it also enables you to measure the progress and outcomes to ensure you attained the goals discussed in the initial consultation.
In my experience I found combining treatments and modalities provided the best outcome for clients. Both approaches complement each other. For example, Botox may smooth fine lines but combined with laser or IPL you are also improving the skin by addressing (pigment and/or vascular lesions) as well as skin texture.
Often our clients will come in focused on a particular concern not realizing a holistic approach offers healthier looking skin.
