Actually, regulation of bioelectricity and release of anions is about the same on both types of products. Since FIR benefits are localized, if you wear a bracelet, the effects will benefit your wrist. If you wear the necklace, it will emit FIR localized around your neck.
Q3 Bracelet or necklace, which one offers better effects?
Yes.
Q2 Can the product be worn in the shower, swimming pool, in the sauna or while sleeping?
The user must remember never to wear the product in natural hot springs. Due to the high sulfur content in hot springs (even silver which is a very stable element will turn black in hot springs), the natural minerals consistent in AERO Technology will change and cause the benefits of Artificer products to be depleted.
Q1 What should I be aware of in order to ensure the longevity of Artificer product use?
