Gua Sha and galvanic devices, which are widely used for home care these days

There are many types of devices there, etc.

I bought a galvanic device a while ago and tried it out.

I didn't use it for very long, but I wasn't really sure if it had any effect.

I also tried using the mask device my sister-in-law gave me because she wasn't using it anymore.

I'm not really sure, haha.

I want to try using Gua Sha too, but there are so many types and I don't know how to use it, so I don't think I'll use it much.

I keep debating whether to buy it or not.

I'm curious to know what the effects are like for those using the recently released devices.

Q&A

Are home care devices and gua sha effective?
