Which technological advancement is NOT typically associated with modern skincare practices?

The application of cold cream is not typically associated with modern skincare practices, as it is a more traditional method of skincare that predates many technological advancements. Cold cream has been used for decades as a moisturizer and cleanser, but it doesn't involve the use of sophisticated technology or contemporary techniques that characterize modern skincare.

In contrast, galvanic currents, high-frequency machines, and laser technology are all recognized advancements that leverage electrical and laser technologies for skincare treatments. Galvanic currents are used to enhance product penetration and facilitate deep cleaning, while high-frequency machines are employed for their antibacterial and healing properties. Laser technology is at the forefront of skincare innovation, utilized for various applications including skin rejuvenation, hair removal, and treatment of skin conditions. These methods are integral to today's skincare routines, focusing on efficacy and targeted treatment strategies, making the choice of cold cream application seem outdated in comparison.
