The reason is that everyone's skin condition is different, and even if you use the same instrument, the effect will be different from person to person. Moreover, some of the videos on Jitterbug may have been retouched or processed with special effects, and the results are not real. In addition, the use of instruments to remove spots also has certain risks, because incorrect use may lead to skin damage or allergic reactions.
Therefore, consumers are advised to understand their own skin conditions and usage methods before considering the use of an instrument to remove blemishes, preferably by consulting with a professional dermatologist. In addition, it is also important to choose reputable brands and channels when shopping for instruments to avoid purchasing fake or shoddy products. It is best to operate in a medical institution or beauty salon so that you can get safer and more effective results.
