LED Light Therapy + Mask Q&A

Hi, I've purchased an at-home LED mask with the intention of using the red light function to improve skin laxity and texture (approx 630nm). However, I've read some alarming journal articles that suggest that exposure to red light can actually accelerate aging long-term. Interested to hear some professional opinions. Thank you

I am looking into buying an at home LED treatment mask. I have heard of these at-home masks you can buy and leave on for 20 minutes with Blue, Green and Red LED lights. I really enjoyed the results I had from my first treatment with a doctor and I would like to do them more regularly. I have recently been scaring really badly with acne and am not sure if it is due to changing skin as I get older. (I am only 22)

I'm really wanna purchase a at home LED light mask. But there are so many different brands out there. Is there a specific type of LED ? Or all the LED lights are same. I'm confused. Please help me

Was wondering what doctor's opinions are about at home LED light therapy masks are and if they're safe? How often should they be used and are they safe following a face lift. Thanks!

For at home LED light masks, have you seen whether LED red light and near infrared light masks produce hyperpigmentation or melasma in skin of color eg Asian skin? Can you use retin A and use an LED and NIR mask?
