Why is it important to know a client's skin type before treatment?

Understanding a client's skin type is crucial for customizing treatments effectively because different skin types have varied needs and responses to various products and techniques. For instance, oily skin may require oil-free products and different types of treatments than dry skin, which may benefit from more hydrating options. Knowing the skin type allows the esthetician to tailor their approach, ensuring that the techniques used and products applied will be suitable and effective for that specific individual's skin characteristics. This customization not only enhances the overall effectiveness of the treatment but also helps in avoiding potential adverse reactions that could arise from using inappropriate products or methods on a client's skin type. Consequently, this tailored approach fosters client satisfaction and trust, leading to better long-term relationships between the esthetician and their clients.
