Start with the model, not a generic device category
A microcurrent, ultrasound or multi-mode device can have different preparation, modes and companion-product requirements. For example, the official product pages for the medicube devices and Quadthera Titan describe model-specific use and accessories. Open the exact product page before using it in a routine.
Keep device pairing product-specific
Do not assume a serum, mask or active step works the same way with every device. Follow the model’s instructions for gel, skincare pairing, intensity, time and frequency. If a product page does not answer a pairing question, keep that step separate until you can check the manufacturer guidance.
Choose skincare after the device instructions are clear
Once you know the device’s required sequence, use the product library to compare cleanser, hydration and moisturizer formats. The library helps you find products by function; it does not certify compatibility with a particular device.
A few useful answers
Can I use any serum with a beauty device?
Do not assume so. Read the official guide for the exact device and follow any companion-product or pairing instructions from its manufacturer.
Do all beauty devices need conductive gel?
No universal rule applies. Some device routines use a companion gel and some have different directions, so check the specific model’s official page.
