Home Care Inquiry: Are there any people who have actually seen the effects of LED masks while thinking about purchasing them?

I've been seeing LED masks advertised frequently lately, so I'm considering buying one. The price is quite high, so I'm hesitant to make the purchase. I'm curious to hear honest reviews from those who have actually used them. I'm not sure if there's a dramatic difference in elasticity or whitening, or if it's more cost-effective to just get another dermatologist treatment. Some people say that daily use helps improve skin texture, but I'd love to hear some real-life advice from actual users.

The biggest advantage is that it can be easily managed at home, but I'm quite lazy, so I'm worried it might just end up being just a decoration. I'm also curious about whether the hassle of applying a special gel is worth it, and whether it has a proven eye protection function so it won't affect my vision. If you know of any cost-effective, proven effective products from specific brands, please recommend them. Also, if you could share how much smoother my skin texture becomes after using it consistently for over a month, that would be incredibly helpful in making a purchasing decision.
