I've already bought Medicube Booster Pro. Is there an effective routine?

I made a big decision to use it for home care. I purchased the Medicube Booster Pro as a beauty device...

Lately, I've been concerned about skin elasticity, and since going to a beauty salon is a burden in terms of time and cost, I bought this to take consistent care of my skin at home. However, now that I've actually bought it, I'm really struggling to figure out how to use it to get the full benefits of this beauty device.

I'm wondering if I just need to follow the instructions, or if there's a specific usage frequency or a combination of cosmetics that works well with it. Some people say the high-frequency mode is good, while others say using it every day might actually cause irritation, so I'm worried I might be missing out on the full benefits of the beauty device...

I'm only using Booster Mode and EMS Mode, but I feel like it's such a waste of money... This price for these features...? 🥹

I can feel something, but unless I look right up close in the mirror, I don't see any difference... T_T

If anyone is actually using the Medicube Booster Pro, please give me some advice on how long you used it to feel the effects of the beauty device and what kind of routine I should incorporate. Since I've already bought it, I want to make the most of it so I don't regret it!!
